Wood Johnson Medical School, 661 Hoes Lane, Piscataway 08854, USA, shiyu@umdnj.edu,
have reviewed (100 references) the implications of lymphocyte apoptosis
for psychoneuroimmunology.
Abstract: Psychological and physical
stress serves as a good example of how the immune and nervous systems
intercommunicate. Stress has been shown to alter susceptibility to various
diseases. While acute stress often enhances immune response, chronic stress
can lead to immunosuppression. Among many parameters commonly examined
upon exposure to chronic stress are the reduction in lymphocyte proliferation
and lymphocyte cellularity. Chronic restraint stress could induce lymphocyte
reduction, and this effect depends on endogenous opioids. The effect of
the endogenous opioids is exerted through increasing the available amount
of a cell death receptor, Fas, and thus an increased sensitivity of lymphocytes
to programmed cell death (apoptosis). Stress-induced lymphocyte reduction
is not affected by adrenalectomy. The review focuses on the role of the
hypothalamic-pituitary-adrenal axis and endogenous opioids and examines
the mechanisms by which chronic stress influences lymphocyte apoptosis.

COE and LUBACH, Department of Psychology, University of Wisconsin,
22 North Charter Street, Madison, WI 53175, USA, ccoe@facstaff.wisc.edu,
write about critical periods of special health relevance for psychoneuroimmunology.
Abstract: Psychological factors have
an influence on immune function at any time in the lifespan of an animal
or human. However there are
critical periods when the implications for health may be greater. Based
on research on nonhuman primates, the authors propose that there are two
such periods: the foetal and neonatal stages of young infants with their
immature immune systems, and also the age-related period of immune senescence
in old people. It is concluded that special attention should be paid in
psychoneuroimmunology to the age of the subjects studied.

ESCH and colleagues, The Mid-Body Medical Institute, Department
of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School,
Boston, MA, USA, tesch@aregroup.harvard.edu,
have reviewed (154 references) the therapeutic use of the relaxation response
in stress-related diseases.
Background: The work aimed at investigating
a possible connection between the relaxation response (RR) and stress-related
diseases, as well as possible common underlying molecular mechanisms and
autoregulatory pathways.
Methods: Peer-reviewed articles only
were analyzed.
Results: The RR has been shown to
be an appropriate therapeutic tool to counteract stress-related disease
processes and certain health restrictions, particularly in immunological,
cardiovascular, and neurodegenerative disorders. Common underlying molecular
mechanisms may exist. Particularly, constitutive or low-output nitric
oxide (NO) production may be involved in a protective or ameliorating
context, whereas inducible, high-output NO release may facilitate detrimental
disease processes. In mild or early disease processes, there is still
a high degree of dynamic balance, and the use of RR may be particularly
relevant here by activating constitutive NO pathways.
Conclusions: RR techniques represent
an important tool to be added to the therapeutic strategies for dealing
with stress-related disease. They may also serve primary or secondary
prevention. Further studies are necessary to elucidate the complex physiology
underlying the RR and its effects on stress-related disease processes.

MAJUMDAR and co-workers, Albert-Ludwigs-University of Freiburg,
Department of Industrial and Organizational Psychology, Freiburg, Germany,
have evaluated the question of whether mindfulness meditation contributes
to health.
Background: This exploratory study
was designed to examine the effects of an 8 week meditation based programme
in mindfulness in a German sample.
Methods: 21 participants with chronic
physical, psychological, or psychosomatic illness were examined in a longitudinal
pre-test and post treatment design with a 3 months follow-up. Emotional
and physical wellbeing, sense of coherence, overall psychological distress,
and satisfaction with life were measured with standardized instruments.
Results: Overall the intervention
led to high levels of adherence to the meditation practice, and satisfaction
with the benefits of the course, as well as lasting and effective reduction
of symptoms. Changes were of moderate to large size, especially in psychological
distress, wellbeing, and quality of life. Positive complementary effects
with psychotherapy were also found.
Conclusions: These findings warrant
controlled studies to evaluate the efficacy and cost effectiveness of
mindfulness-based stress reduction as an intervention for chronic physical
and psychosomatic disorders.

SCHOFIELD, Nursing, University of Sheffield, evaluated Snoezelen [a multiplicity of different activities on the sensory level – light, noises, feelings, smells and taste] for relaxation in chronic pain management.
Background: Snoezelen is a sensory environment purporting to produce relaxation. The study was designed to test Snoezelen against conventional relaxation in the pain clinic setting.
Methods: Pain, anxiety, depression, coping. self-efficacy, and disability were measured. Assessments were carried out at three time intervals.
Results: The experimental group experienced significant reductions in pain (p = 0.002), and an improvement in self-efficacy (p = 0.02), as well as for sickness impact on the following scales: physical (p = 0.009), psychosocial (p = 0.009), recreation (p = 0.001), sleep (p = 0.001) and total sickness impact (p = 0.001). The control group experienced significant improvements in the psychosocial scale (p = 0.05), sleep scale (p = 0.01) and total sickness impact (p = 0.004).
Conclusions: The study suggests that Snoezelen environments are as effective as, if not slightly better than, teaching relaxation in the traditional pain clinic environment for chronic pain patients.

STETTER and KUPPER, Oberbergklinik Extertal for Psychotherapy, psychiatry, and Psuchosomatic Medicine, Brede 29, D-32699 Extertal, Germany, stetter@oberbergkliniken.de, analyze clinical outcome studies of autogenic training.
Background: Autogenic training is a self-relaxation procedure eliciting a psychophysiological relaxation response.
Methods: 73 controlled outcome studies were found published between 1952 and 1999. 60 studies, of which 36 were randomized controlled trials (RCTs), qualified for inclusion in this meta-analysis.
Results: Medium to large effect sizes were found in pre treatment/post treatment comparisons, with the RCTs showing larger effects. When autogenic training was compared to real control conditions, medium effects were found. Comparison of autogenic training to other psychological treatments mostly resulted in no effects or small negative effects. Unspecific autogenic training effects such effects on mood, cognitive performance, quality of life, and physiological variables, tended to be larger than main effects. A separate meta-analysis for different disorders revealed a significant reduction of the heterogeneity of effect sizes.
Conclusions: Positive effects of autogenic training in the meta-analysis of at least 3 studies were found for tension headache/migraine, essential hypertension, coronary heart disease, bronchial asthma, somatoform pain disorder, Raynaud’s disease, anxiety disorders, depression, and functional sleep disorders.
Stetter F, Kupper S. Autogenic training: a meta-analysis of clinical outcome studies. Applied Psychophysiology and Biofeedback 27 (1): 45-98, Mar 2002.
Comments: These are impressive results for a treatment which is probably unknown outside of the cognoscenti in the psychological world. Positive effects of autogenic training for such serious conditions such as hypertension, heart disease, asthma, Raynaud’s disease and depression need to become more widely known in the clinical world, to provide patients with real choice in their treatment.

Southern Station Box 5309, Hattiesburg, MS 39406-5309, USA, E: pawlow@musc.edu,
measured the impact of progressive muscle relaxation on salivary
cortisol.
Background:
The purpose of the study was to examine whether acute relaxation training,
conducted on two separate occasions, would be associated with reliable
reductions in subjective and physiological indices of stress.
Methods:
46 subjects were led through an abbreviated progressive relaxation
training (APRT) during two sessions spaced one week apart.
15 control subjects were asked to sit quietly in the laboratory
for an equal length of time. Heart rate, state anxiety, perceived
stress, and salivary cortisol were measured pre and post treatment.
Results:
Subjects in the experimental group
had significantly lower heart rate, state anxiety, perceived
stress and salivary cortisol than control subjects. They reported
higher levels of relaxation.
Conclusions: The results of this study may have implications
for the use of relaxation training in enhancing immune function.

CURTIS, Marie
Curie Centre, Newcastle-upon-Tyne, UK, reported on an audit of a pilot
hypnotherapy service – provided for patients, carers and staff – at
a specialist palliative care unit in Newcastle-on-Tyne.
Background: Existing
data suggest that hypnotherapy may be useful for patients,
their carers and healthcare professionals in palliative
care settings. All parties may benefit from stress reduction, and
patients may also be able to find ways to cope better with their illness
and the prospect of dying.
Methods: The
investigator assessed the demand for the hypnotherapy service,
practical issues presented by providing the service, and
benefits as perceived by the clients and the hypnotherapist. Qualitative
and quantitative data, covering a period of 5 months and involving
11 clients (4 patients and 7 staff members), were
obtained using questionnaires and other evaluation methods.
Results:
All the clients appeared to benefit from
the service in terms of improved coping and relaxation. 82%
of the clients reported that hypnotherapy had helped to improve the
particular problem for which they had sought the service and 91%
reported a general overall benefit from the therapy.
Discussion:
The author discusses additional issues, including
the therapeutic relationship, non-attendance and the therapy
environment.
Conclusion:
This audit of a pilot hypnotherapy service
indicated that hypnotherapy in the palliative care setting
can benefit both patients and healthcare providers.

JACOBS, Harvard
Medical School and Beth Israel Deaconess Medical Center, Boston, Massachusetts
02215, USA, gjacobs@caregroup.harvard.edu,
reviewed (30 references) evidence for the benefits and cost-effectiveness
of mind-body therapies (incorporating the ‘relaxation response’
and/or cognitive therapy), particularly in relation to stress-related
conditions.
Background:
Over the last 20 years, several valid scientific
studies have been conducted demonstrating that the relaxation response
and mind-body therapies are beneficial in alleviating many stress-related
conditions and conditions that are exacerbated by stress. Furthermore,
in recent years it has emerged that mind-body therapies can improve
the outlook for patients with coronary heart disease
and can bolster the immune system. The mechanism of action is thought
to include reduction of sympathetic nervous system activity
and enhancement of the parasympathetic division of the autonomic
nervous system. The overall effect of this is to restore the natural
homeostatic balance of the body. Studies have also shown that cognitive
therapy may be as effective if not more so than pharmacological
interventions for treating clinical depression.
Discussion:
The author reviews a range of studies
that have demonstrated beneficial effects of mind-body therapies
(involving the relaxation response and/or cognitive therapy) on headaches,
sleep problems and cardiovascular conditions. The evidence
indicates that mind-body therapies are effective and can
reduce the costs of patient treatment. However, mind-body therapies
should not be seen as a ‘cure-all’ and it is recommended
that they be used in an integrated manner alongside conventional
medical treatment.

KJELLGREN and colleagues,
Department of Psychology, Karlstad University, Karlstad, Sweden,
investigated the possible benefits of rest/relaxation in a flotation
tank to patients suffering chronic muscle tension/pain.
Background:
Floating and relaxing in a high-salt content
flotation tank is a form of restricted environmental stimulation
technique (REST) termed ‘flotation-REST’.
Methods:
This randomized, controlled study involved
14 men and 23 women suffering from chronic muscular pain/tension
in the neck and/or back. 17 of the subjects served
as controls, while 20 were given the opportunity to use
the flotation-REST technique in a flotation tank (filled with water
containing a very high salt concentration) up to nine times over
a 3-week period.
Results:
The flotation-REST technique significantly
reduced perceived pain that was of the most severe intensity,
but did not affect perceived pain that was of low intensity. In patients
who undertook flotation-REST, blood levels of 3-methoxy-4-hydroxyethyleneglycol
(a metabolite of noradrenaline) were significantly reduced
following treatment, whereas such levels in controls were unchanged. Flotation-REST
did not significantly affect endorphin levels. However, patients in the
flotation-REST group did report experiencing elevated optimism
and reduced anxiety and depression and were better able to fall
asleep at night compared with controls.
Conclusion: The
results indicate that the flotation-REST technique may offer benefits
for patients suffering from chronic pain.

Comments:
The above research studies show how powerful mind/body therapies are for
a broad spectrum of conditions, from muscular pain, coping with the distress
of dying, headaches, cardiovascular and sleep problems. These techniques
and approaches need to be integrated into medical education, as well as
made available as add-on services to conventional health services.

VEMPATI and TELLES,
Swami Vivekananda Yoga Research Foundation, Chamarajpet, Bangalore, India,
studied the effects of yoga-based guided relaxation compared
with simply lying down and resting on sympathetic nervous system activity
in adult males.
Methods: This
study involved 35 healthy men aged 20-46 years. The subjects underwent
two types of relaxation: 1) yoga-based guided relaxation
and 2) rest lying down. Measures of autonomic nervous system activity
(including heart rate by ECG and skin conductance by galvanic skin response),
oxygen consumption and volume of air breathed were monitored.
Results: Assessments
of autonomic indicators were completed for 15 subjects and those for oxygen
consumption and breath volume for 25 subjects. Oxygen consumption decreased
significantly and breath volume increased significantly after
guided relaxation. The two types of relaxation produced similar
reductions in heart rate and skin conductance. During
guided relaxation, there was a reduction in the power of the
low frequency (LF) component of the heart rate variability spectrum
and an increase in the power of the high frequency (HF) component,
which suggested a reduction in sympathetic nervous system activity.
Further analysis revealed that subjects who had a baseline ratio of LF/HF
greater than 0.5 demonstrated a significant reduction in the ratio
after guided relaxation; whereas, subjects with a baseline
ratio less than or equal to 0.5 did not show this change.
Conclusion: Yoga-based
guided relaxation decreased sympathetic nervous system activity depending
on subjects’ baseline levels.

WEBER and colleagues,
Clinic for Internal Medicine-Psychosomatics, Charite Campus Virchow Clinic,
Medical School of the Humboldt University, Augustenburger Platz 1, 13353,
Berlin, Germany, E: cora.weber@charite.de,
examined the effects of a stress management/relaxation programme
on psychological status and stress-related immune function
in patients suffering from chronic tinnitus.
Background: Tinnitus
can cause severe psychological stress to sufferers. Chronic stress as a
consequence of chronic tinnitus, as with other chronic stressors, is likely
to have long-term effects on physiological parameters of stress including
stress-related immune responses.
Methods: The
study enrolled 45 tinnitus sufferers and 13 non-tinnitus subjects.
The non-tinnitus participants (NTPs) and 26 of the tinnitus
sufferers (TPs) entered a 10-week standardized relaxation programme,
while the remaining 18 tinnitus sufferers were assigned to a waiting
list (controls; TCs). The researchers evaluated subjects’ mood,
perceived stress, global quality of life and tinnitus disturbance at baseline
and after the 10-week treatment period, and they measured indicators
of stress-related immune function changes (blood levels of tumour necrosis
factor-alpha [TNF-alpha], interleukin-6 [IL-6] and IL-10)
at baseline, during treatment and at the end of treatment.
Results: The
TP group experienced significantly less perceived stress, anxious
depression, anger and tinnitus disturbance after the 10-week
relaxation programme and showed reduced levels of TNF-alpha compared
with baseline measurements. Levels of IL-6 and IL-10 remained unchanged.
No relevant changes in psychological parameters or stress-related immune
system indicators occurred in the TC or NTP group.
Conclusion: Sufferers
of chronic tinnitus gained improved stress management skills with
the relaxation programme used in this study and experienced less psychological
distress as a result. The study findings also suggest that TNF-alpha
may be useful as an indicator of psychological stress.

KIECOLT-GLASER and
colleagues, Department of Psychiatry, The Ohio State University College
of Medicine, 1670 Upham Drive, Columbus, Ohio 43210, USA, Kiecolt-Glaser.1@osu.edu,
reviewed (176 references) literature providing evidence that links negative
emotions with the onset and course of a range of illnesses/conditions
that can be influenced by the immune system.
Background: Inflammation
has been associated with a wide range of age-related conditions such as
cardiovascular disease, osteoporosis, arthritis, type 2 diabetes, certain
cancers, Alzheimer’s disease, frailty and functional decline and
periodontal disease. Negative emotions and stress can
directly stimulate production of proinflammatory cytokines, which
influence these and other conditions. Negative emotions can also help
prolong infection and delay wound healing, resulting in
sustained production of proinflammatory mediators.
Discussion:
The authors of this review argue that negative emotions and distress
may contribute to dysregulation of normal immune function,
and that this may be one core mechanism precipitating the appearance
of and/or fuelling the progression of a range of common diseases and
conditions of diminished health. Factors that reduce negative
emotions, such as close personal relationships, may therefore enhance
health partly through their beneficial effects on immune and
hormonal functions.

reviewed (155 references) early and recent research relevant to
the field of psychoneuroimmunology (PNI).
Background: Brain-immune
modulation is now a well-established
phenomenon, with an explosion of research and literature on the subject
appearing over the last decade. The history of the field
goes back much farther, however, largely under the auspices of
studies in psychosomatic medicine. This article reviews that history
and speculates on where PNI may take us in the future.
Methods:Human
PNI studies published since 1939, particularly in the journal Psychosomatic
Medicine, are reviewed here. Studies were grouped according to key
themes, such as: stressor duration and characteristics
(e.g. laboratory stressors, short-term stressors, chronic stress); influences
of psychopathology, personality or interpersonal relationships;
and immune responses to behavioural interventions.
The authors also examined population trends, changes and developments
in immunological assessment methods, health outcomes and
likely future directions in the field of PNI.
Results:The
body of evidence is now sufficient to conclude that psychosocial stressors
or interventions can cause alterations in immune function that
can result in actual changes in health. The strongest evidence
of this is in the areas of infectious diseases and wound healing.
In addition, it is now apparent that the onset and course of a range
of common diseases are significantly influenced by proinflammatory
cytokines; such conditions range from cardiovascular disease
to loss of function and frailty such as those commonly associated
with ageing. Numerous studies have demonstrated that negative emotions
(e.g. anger, depression, despair) and stressful experiences
can directly stimulate production of proinflammatory cytokines;
chronic or recurrent infections are also indirect stimulators
of these agents. Thus, the wide range of health risks associated
with negative emotions may be mediated, in large part, by distress-related
disturbances of normal immune function.
Conclusion:The
facts of PNI have far-reaching implications for basic biological
sciences, academic and clinical medicine and
the effectiveness of healthcare.

Comment:Kiecolt-Glaser
are amongst the giants in the field of psychoneuroimmunology. This review
summarizes the vast research which substantiates how the mind has a powerful
influence upon health, as also discussed in the featured cover
stories. The importance of psychosocial and emotional factors to disease
and general health must now finally be given the emphasis they merit,
starting with the medical school curriculum and finishing up in medical
consultations placing the overall wellbeing of the patient as the supreme
consideration.
REID and colleagues, School of Psychology, Murdoch
University, Perth, Western Australia 6150, Australia, investigated
whether stress management techniques could reduce the incidence
or severity of symptoms of colds and ‘flu in students undergoing
college exams.
Methods: Subjects
were 27 university students. They were assessed in the periods
before and after their exams on the incidence of upper respiratory
tract symptoms, levels of negative affect (low mood) and the
secretion rate of secretory immunoglobulin A (sIgA), an antibody
found in mucosal linings (such as in the respiratory tract) of the body
that often reflects the general immune status of the person. Assessments
were made during 5 weeks prior to the start of treatment, during 4
weeks of treatment (participation in a stress management programme;
SMP) and for 8 weeks after treatment. A further 25 students
who did not participate in the stress management programme served as controls.
Results: Symptoms
decreased in the SMP group, but not
in control students, during and after the exam period. sIgA
secretion increased significantly after individual sessions
of relaxation, but resting levels of secretion did not increase over
the period of the study as a whole. In both groups, mood improved
after the examination period and was not affected by SMP
treatment.
Conclusion:The
number of days of illness due to colds and ‘flu were reduced
by stress management. The effects were independent of low mood
or sIgA secretion rate. The precise aspect of the treatment responsible
for reducing symptoms remains unclear. However, the results indicate that
psychological treatments can be useful for reducing symptoms
of upper respiratory tract infections.

TAKAHASHI and colleagues, Department of Clinical Neuroscience,
Psychiatry, Osaka University Graduate School of Medicine, D3, Suita City,
Osaka 565-0871, Japan, kiyotake@psy.med.osaka-u.ac.jp,
investigated the effects of laughter, including the experiential
aspects of laughter, on a measure of immune function, natural
killer cell activity (NKCA).
Background: Positive emotions
are thought to be beneficial to health and immune status. In previous
studies, the effects of laughter on NKCA were examined, but results were
inconclusive due to methodological limitations of the studies. The researchers
therefore designed and carried out a more rigorous study to investigate
the relationship between laughter and NKCA.
Methods:In
a cross-over design study, NKCA was measured in 21 healthy male subjects
before and after they watched a 75-minute comedy film and
a non-emotive film (control) on different days. Magnitude of
laughter was measured (as an indicator of emotional expression)
by electromyographic recordings (recordings of muscle electrical
activity) from the left major zygomatic muscle of the face during
film-watching. The subjects rated themselves on the pleasantness
of the comedy film using a visual analogue scale (VAS). The researchers
also rated the subjects’ mood state before and after watching the
film using the Profile of Mood States (POMS) scale.
Results: Watching
the comedy film resulted in significant
increases in NKCA (26.5-29.4%). Watching the non-emotive film
had no effect on NKCA (27.1-24.8%). Elevated NKCA was associated
with lowered scores on the negative mood scales of POMS
(suggesting an association with improvement of mood). No associations
were found between NKCA elevation and self-rated pleasantness or magnitude
of laughter. Further analysis of the subjects and data suggested that
subjects with high scores of depression and anger/hostility
had a suppressed NKCA response to laughter (i.e. negative mood
suppressed the NKCA elevation caused by laughter). Subjects’ NKCA levels
before and after watching the comic film seemed to be somewhat related
to the self-rated pleasantness score they assigned the comedy film. NKCA
levels per se were not correlated with magnitude of laughter measures.
Conclusion:The
results indicated that elevations of NKCA and NKCA levels
before and after watching a comedy film are associated with the experiential
aspects of laughter rather than its expressive aspects.

JOHNSEN and LUTGENDORF, Department of Psychology, University
of Iowa, Iowa City 52242, USA, erica-johnsen@uiowa.edu,
examined whether the ability to visualise mental imagery affected
the psychological and physiological responses to stress and relaxation.
Methods: 176 subjects
completed two study sessions. In session 1, subjects completed the Creative
Imagination Scale and were assigned to either a stress or a relaxation
condition based on their imaging scores. In session 2, subjects either
watched a stressful film (‘stress condition’) or listened to a
relaxation tape (‘relaxation condition’). Stress and
mood were assessed before and after the stress/relaxation conditions
and finger temperature was measured during the conditions.
Results:The
stress/relaxation conditions resulted in changes in finger temperature
and self-reported scores of stress and mood, indicating that the experimental
conditions were effective. ‘High imagers’ reported greater stress
after the stressful film and less stress and negative mood
after the relaxation tape compared with ‘low imagers’. Imagery ability
did not predict levels of negative mood following the stress condition
or changes in positive mood or finger temperature during either of the
conditions. In the stress condition, the observed association
between imagery ability and psychological stress was partly
due to expectations of stress. Conversely, in the relaxation condition,
observed responses were unrelated to expectations of relaxation.
Conclusion:Subjects
with higher imagery ability may show greater subjective responses
to both stress and relaxation. In stressful situations,
expectation of stress may contribute to the effects of imagery ability
on psychological stress.

Medical Clinic and the Department of Public Health in San Francisco, CA,
USA, bethroth@snet.net, investigated
whether a programme of mindfulness-based stress reduction (MBSR) could
reduce the usage of primary healthcare services by people
living in an inner city area.
Background: Previous
studies of MBSR have examined its ability to reduce symptoms in
relation to general health problems in ‘middle class’ and ‘working class’
populations.
Methods: The
researchers reviewed medical charts from the Community Health Center,
Meriden, Connecticut, USA. They compared the number of and diagnoses resulting
from health centre visits during the year before and the year
after patients entered an 8-week MBSR programme. The review
covered healthcare utilization by 73 patients who completed the
MBSR programme (54 in Spanish, 19 in English). Analysis focused on 47
of these patients, for whom data were available for a complete year
before and after the programme.
Results: The
number of chronic care visits decreased significantly in the subgroup
of 47 patients. 36 of these 47 completed the MBSR programme in
Spanish – in these, total medical visits and number of
chronic care visits both decreased significantly.
Conclusion: MBSR
may reduce healthcare costs of inner city
patients by decreasing the number of visits to their GPs.

assessed the efficacy of yoga in the treatment of patients with
epilepsy.
Background: Stress
is thought to be an important factor in precipitating seizures.
Yoga can induce relaxation and reduce stress; effects
on the electroencephalogram (EEG) and autonomic nervous system have been
reported. If effective in epilepsy, it would be an attractive therapeutic
option.
Methods: Reports
of controlled trials (search criteria: randomized control trials
and controlled clinical trials) of the treatment of epilepsy with yoga
were obtained by searching the following: the Cochrane Epilepsy Group
trial register; the Cochrane Controlled Trials Register (The Cochrane
Library Issue 4, 1998); MEDLINE for articles published up to the middle
of 1998; and registries of the research council for complementary medicine.
References of all the identified studies were also searched. Members of
the Neurological Society of India, several neurophysiology institutions
and yoga institutes were also contacted to find information about any
ongoing studies or studies published in nonindexed journals or unpublished
studies. The two reviewers extracted the data independently. Any discrepancies
were resolved by discussion. The main outcomes assessed were: percentage
of patients rendered seizure free; number of patients with more than 50%
reduction in seizure frequency or duration; and overall reduction in seizure
frequency. Analyses were on an intention-to-treat basis.
Results: Only one
study met the selection criteria. 32 patients
were recruited: 10 to sahaja yoga, 22 to control treatments.
All patients continued with anti-epileptic medication. Randomisation was
by roll of a dice. 4 patients treated with yoga were seizure
free for 6 months compared with none in the control
groups. The odds ratio (OR) for yoga treatment versus sham yoga was 14.5
and for yoga versus no treatment was 17.3. 9 patients treated with
yoga had more than 50% reduction in seizure frequency
compared with only one among the controls. The OR for yoga versus
sham yoga was 81 and for yoga versus no treatment was 158.3. Yoga-treated
patients had a decrease in the average number of attacks
per month compared to baseline. The weighted mean difference between
yoga versus sham yoga was –2.1 and between yoga versus no treatment was
–1.1. 7 of the 10 patients treated with yoga had a more
than 50% reduction in seizure duration, compared with none
among the 22 controls. The OR for yoga versus sham yoga was 45 and
for yoga versus no treatment was 53.57.
Conclusion: No
reliable conclusions could be drawn regarding
the efficacy of yoga as a treatment for epilepsy. Further
studies are needed.

TAKEICHI and SATO, Department of
Psychiatry, Saga Medical School, Japan examined the possibilities
that ill-health, lifestyle illness and stress-related disease
are a clinical expression of the ‘anxiety-affinitive constitution’.
Background: Previously,
the researchers used visual observation of the sublingual vein (which,
according to Oriental psychosomatic research, can give early indication
of vital energy stagnation and blood stasis) for diagnostic purposes.
They developed the concept of the ‘anxiety-affinitive constitution’,
based on unbalanced Qi, blood and body fluid in ill health, as a causative
factor for stress-related diseases and life-style illnesses.
The present study develops this concept through the diagnosis and treatment
of functional subclinical psychosomatic disorders.
Methods: The
study involved 197 medical school students with a diagnosis of
functional subclinical psychosomatic disorders (ill health).
Results: The
researchers found that the trait ‘anxiety’, forming the core of
the ‘anxiety-affinitive constitution’, was linked to Dr. Lester
Breslow’s 7 good health habits and the manner of respiration.
Treatment of functional subclinical psychosomatic disorders in 8 medical
students with kampo medication and, in particular, relaxation
training (RT) produced lower scores for STAI-trait anxiety and
transformed respiration from a thoracic pattern to a balanced
thoracic and abdominal pattern. A high score for anxiety
trait correlated with the formation of inappropriate health habits
and habituation of inadequate (thoracic pattern) respiration.
Conclusion: The
researchers concluded that individuals with an anxiety-affinitive constitution
will develop lifestyle illness or stress-related diseases
unless their constitution is improved with kampo medication and/or
RT.

SCHEUFELE, Uniformed
Services University of the Health Sciences, Bethesda, Maryland, USA examined
whether effects of individual elements of relaxation could be
measured and whether there were specific effects, or whether relaxation
resulted from a generalized ‘relaxation response’.
Methods: 67
healthy male volunteers were exposed to a stress manipulation condition
and then to a) progressive relaxation, b) music, c) attention
control or d) silence. Measures of attention, relaxation and
stress responses were obtained during each phase of the study.
Results: All four
groups showed a reduction in physiological
arousal following their relaxation or control condition (as shown
by their performances on behavioural measures of attention), as well as
a decreased heart rate. However, progressive relaxation
resulted in the greatest effects on behavioural and self-report
measures of relaxation.
Conclusion: The
findings suggest that cognitive cues provided by stress management
techniques contribute to relaxation.

CRUESS and colleagues, Department of Psychology,
University of Miami, Coral Gables, Florida 33124-2070, USA examined
salivary cortisol and mood during relaxation training
in symptomatic, HIV-positive gay men.
Methods: In
30 symptomatic, HIV-positive gay men participating in a 10-week, group-based,
cognitive-behavioural stress management intervention, cortisol levels
in saliva samples and mood were assessed within the therapy sessions immediately
before and after 45-minute relaxation exercises. Subjects also recorded
their stress levels and compliance with daily home relaxation practice.
Results: Pre-session
salivary cortisol levels decreased over the course of the 10-week period
and were associated with decreases in global measures of total
mood disturbance and anxious mood and with decreases in
self-reported stress level during home practice. Greater reductions
in cortisol levels occurred during the first three therapy sessions and
were associated with more frequent home relaxation practice.
Conclusion: Salivary
cortisol appears to represent an objective
neuroendocrine marker for changes in anxiety and distress
observed during relaxation training in symptomatic, HIV-positive
men.

RIABUS and KOLOSOVA, Eastern Europe, analysed
the efficiency of electromyographic (EMG) biofeedback (BFB) in the treatment
of tension type headache (TTH).
Methods: 50 patients with episodic
and chronic TTH were treated by a standard course of BFB therapy (10 sessions).
Results were compared with data in a comparison group (12 patients receiving
lerivon therapy) and in controls (15 healthy individuals). Outcome measures
include severity index, psychological data, amplitude of EMG of frontal,
temporal, trapezius, and orbicularis oris muscles.
Results: The best results were obtained
in the episodic TTH group 87%. In the chronic TTH group the efficiency
was lower: full effect: 26%; partial: 35%; no effect: 39%. The 6-month
period following treatment showed that BFB effect was more protracted
than that of the pharmacological therapy.

Comments: The results of the above
study indicated that EMB biofeedback treatment of tension headaches had
a more long-lasting effect than drugs. I look forward to the day when
we are all able to use this technique for our headaches.

previously reported that docosahexaenoic acid (DHA) prevented aggression
from increasing during time of mental stress. The authors further studied
whether DHA intake modified stress response in medical students.
Methods: 14 medical students, randomly
assigned, double-blind, to either control or DHA group, participated in
the current study. Students in the control group (4 males and 3 females)
took 10 control capsules/d, each capsule with 280 mg of mixed plant oil;
the DHA group (4 males and 3 females) took 10 DHA capsules/d containing
1.5 g DHA for a period of 9 weeks, during which time subjects underwent
more than 20 stressful final exams. At the outset and end of the study,
plasma catecholamines (epinephrine, norepinephrine (NE) and dopamine)
and cortisol were measured; a 75 g oGTT was also performed.
Results: There were intra- or intergroup
differences in plasma glucose concentrations. NE concentrations were significantly
diminished following DHA administration. The other catecholamines and
cortisol did not change significantly. Plasma ratios of epinephrine to
NE increased in each DHA subject and intergroup differences were significant.
Conclusions: The effects of DHA may
be applied to people under long-lasting psychological stress to prevent
stress-related diseases.

SADIGH, Department of Psychology, good Shepherd
Hospital, Allentown, PA 18103 USA writes that recurrent and frightening
dreams are commonly experienced by patients who suffer from post-traumatic
stress disorder after an automobile accident. These, if left untreated,
may result in severe distress along with physical, emotional and psychophysiological
effects. The author presents a single case study investigating
the effects of the standard autogenic exercises in reducing
frequency and severity of post-traumatic nightmares in a survivor
of a car crash.
Methods: The patient was instructed
in standard autogenic exercises and autogenic abreaction, as well as two
additional organ-specific formulas in order to improve her sleep.
Results: The interventions were
successful in effectively treating the patient's distressing nightmares.
Follow-up data suggested that the treatment effects persisted following
termination of therapy. The author discusses suggestions for future investigations.

BURNS and colleagues, Department of Psychology, University
of South Alabama, Mobile 36688, USA evaluated the effects of listening
to different types of music upon physiological indicators of relaxation.
Methods: Fifty-six undergraduate students,
24 male and 32 female, mean age 21, were randomly assigned to listen either
to classical, hard rock, self-selected relaxing music or no music. Participants'
relaxation level, skin temperature, muscle tension and heart rate were
evaluated prior to and following exposure to a music condition.
Results: Skin temperature decreased
for all conditions; classical, self-selected relaxing music and no
music groups reported significant increases in feelings of relaxation.
Conclusions: These results partially
support the hypothesis that classical and self-selected relaxing music
may increase perceptions of relaxation to a greater degree than listening
to hard rock music. No differences were found between different types
of music upon physiological indicators of arousal. The authors discuss
implications for using music to reduce stress.

studied the effects of using relaxation and loud rhythmic counting
upon the 'freezing' phenomenon in Parkinson's disease (PD).
Background: The 'freezing' phenomenon
was studied in a 77-year old male patient with Parkinson's disease (PD).
Motor blocks occurred several times per day, lasting between 2 and 5 minutes,
which affected mainly walking. Freezing was elicited and intensified by
external factors (limited space and room to move), as well as by negative
cognitions, negative emotions and tension.
Results: The most effective behaviour
to overcome freezing was a combination of relaxation and loud rhythmic
counting. Effectiveness in overcoming freezing correlated positively
with self-rated mobility prior to trials. Relaxation training improved
self-rated mobility.
Conclusions: Relaxation training and
cognitive techniques should be used to reduce tension, negative thoughts
and negative emotions contributing to freezing, and to improve the ability
to cope with freezing.

studied the effects of relaxation training upon fear of snake phobics.
Methods: 20 carefully selected snake
phobics were exposed to a caged snake for 8 trials on a conveyor apparatus.
During the first and eighth trials the subjects brought the snake toward
themselves as closely as tolerable; records were kept of the end-of-trial
distances remaining between the subject and the snake. For the 6 intervening
trials the experimenter placed the snake a standard distance away; records
were kept of the subjects' heart rates and skin-conductance levels prior
to and during the exposures and of their self-reported fear intensities
following the exposures. Half of the subjects had received six sessions
of progressive relaxation training prior to the exposures.
Results: Compared to those subjects
who had received relaxation training, those who had not received relaxation
training had heightened arousal and fear levels in the context of in vivo
exposure. Relaxation worked by lowering arousal throughout the course
of exposure, not by hastening or facilitating arousal decrement during
exposure.
