Relaxation therapy for hypertension: setting-specific effects.
We determined the effect of relaxation therapy for hypertension in patients whose blood pressure remained elevated despite the use of antihypertensive medication. The effect was assessed in multiple settings, including the relaxation therapist's office, the Hypertension Clinic, and the patient's natural environment, the latter using 24-hour automated ambulatory blood pressure measures. Nineteen patients were randomized either to temperature biofeedback-assisted relaxation or to an attention control, "stress education." Antihypertensive medication was kept constant. In the behavioral therapist's office, blood pressure decreased in equivalent amounts with both treatments. Hypertension Clinic nurse blood pressure remained stable or increased with both treatments, but again there was no difference between treatments. Ambulatory blood pressure increased with relaxation therapy and decreased with stress education, the effect being significant for diastolic pressure. The effects on ambulatory blood pressure were limited to the waking hours. The only variable that showed superior effects for relaxation therapy was physician-determined blood pressure. These results call into question the generalizability of the effects of relaxation therapy from one setting to another.
Relaxation therapy in the treatment of hypertension. A review.
The literature on the use of relaxation or relaxation-like procedures (relaxation therapy) in the treatment of hypertension was critically reviewed. Relaxation therapy resulted in greater reduction of blood pressure than placebo or other control procedures. A positive relationship was found between the average blood pressure decrease and the average pretreatment pressure. Relaxation-like therapies shared the features of muscular relaxation, regular practice, mental focusing, and task awareness. Research on the relative contributions of these components indicated that task awareness adds to the treatment effect in the laboratory setting, and that regular practice is necessary for optimal results in the clinical setting. The role of muscular relaxation and mental focusing is unclear. We concluded that relaxation therapy may become a useful adjunct to medication in the clinical management of hypertension, especially for individuals whose blood pressures remain high despite pharmacological treatment.
Relaxation therapy and continuous ambulatory blood pressure in mild hypertension: a controlled study.
OBJECTIVE: To determine the long term effects of relaxation therapy on 24 hour ambulatory intra-arterial blood pressure in patients with mild untreated and uncomplicated hypertension. DESIGN: Four week screening period followed by randomisation to receive either relaxation therapy or non-specific counselling for one year. Ambulatory intra-arterial blood pressure was measured before and after treatment. SETTING: Outpatient clinic in Amsterdam's university hospital. SUBJECTS: 35 Subjects aged 20-60 who were being treated by general practitioners for hypertension but were referred to take part in the study. At three consecutive screening visits all subjects had a diastolic blood pressure without treatment of 95-110 mm Hg. Subjects were excluded if they had damaged target organs, secondary hypertension, diabetes mellitus, a cholesterol concentration greater than 8 mmol/l, or a history of malignant hypertension. INTERVENTIONS: The group allocated to relaxation therapy was trained for eight weeks (one hour a week) in muscle relaxation, yoga exercises, and stress management and continued exercising twice daily for one year with monthly visits to the clinic. The control group had the same attendance schedule but had no training and were requested just to sit and relax twice a day. All subjects were asked not to change their diet or physical activity. MAIN OUTCOME MEASURE: Changes in ambulatory intra-arterial blood pressure after one year of relaxation therapy or non-specific counselling. RESULTS: Mean urinary sodium excretion, serum concentration of cholesterol, and body weight did not change in either group. Diastolic pressures measured by sphygmomanometry were 2 and 3 mm Hg lower in subjects in the relaxation group and control group respectively at the one year follow up compared with initial readings. The mean diastolic ambulatory intra-arterial pressure during the daytime had not changed after one year in either group, but small treatment effects could not be excluded: the mean change for the relaxation group was -1 mm Hg (95% confidence interval -6 to 3.9 mm Hg) and for the control group -0.4 mm Hg (-5.3 to 4.6 mm Hg). Mean ambulatory pressure in the evening also had not changed over the year, and in both groups nighttime pressure was 5 mm Hg higher. The variability in blood pressure was the same at both measurements. CONCLUSIONS: Relaxation therapy was an ineffective method of lowering 24 hour blood pressure, being no more beneficial than non-specific advice, support, and reassurance--themselves ineffective as a treatment for hypertension.
Noradrenergic hyperactivity in primary hypertension; central and peripheral markers of both behavioral pathogenesis and efficacy of sympatholytic and relaxation therapy.
The effects of clonidine or relaxation therapy were determined in two separate groups of patients with primary hypertension. Ten patients were treated with clonidine monotherapy for 3 months. There were concurrent reductions of blood pressure, plasma and CSF norepinephrine, all p less than 0.01. The changes of blood pressure and norepinephrine were correlated, p less than 0.05 and 0.01, respectively. Thirty patients received hygienic instructions, and 17 of them had relaxation training in addition. Relaxation lowered blood pressures, p less than 0.01, the reduction of blood pressure was related to baseline plasma norepinephrine, p less than 0.05, and greater in patients with "raised" plasma norepinephrine, p less than 0.02. Plasma norepinephrine was lowered after hygienic therapy, p less than 0.05, the change was not significant after relaxation training. Arterial pressure elevation appears to be related to raised plasma norepinephrine. This noradrenergic hyperactivity is a marker for blood pressure responsiveness to sympatholytic therapy with clonidine or relaxation techniques.
Relaxation therapy for hypertension. Comparison of effects with concomitant placebo, diuretic, and beta-blocker.
We compared the effects of relaxation therapy in hypertensive patients taking placebo, a beta-blocker (atenolol, 100 mg/d), or a diuretic (chlorthalidone, 50 mg/d), and we also compared the effects of relaxation therapy with the effects of the latter two drugs alone. Blood pressures were measured not only in the relaxation therapists' office and at a hypertension clinic, but also in the patient's environment by means of 24-hour ambulatory blood pressure recordings. The effect of relaxation therapy, while statistically significant, was modest. There was no generalization of effect to ambulatory blood pressure. Atenolol was significantly more effective than relaxation in reducing both systolic and diastolic pressure. Chlorthalidone was significantly more effective than relaxation in reducing systolic but not diastolic pressure in the hypertension clinic only. The long-term effects of relaxation were independent of concomitant drug use, but within the actual relaxation sessions blood pressure dropped further during chlorthalidone than during placebo or atenolol treatment.
Relaxation therapy lowers blood pressure more effectively in hypertensives with raised plasma norepinephrine and blunts pressor response to anger.
The effects of relaxation therapy on blood pressure and neural responses to "social stress"-anger instigation were determined in 30 male patients with mild primary hypertension. "Social stress"-anger induced increases in systolic and diastolic blood pressures (both p less than 0.01) and plasma norepinephrine (p less than 0.05) before therapy. Diastolic blood pressure before and during anger challenge were related to simultaneous plasma norepinephrine (r = 0.56, p less than 0.01 and r = 0.39, p less than 0.05). Relaxation reduced resting diastolic blood pressure (p less than 0.01), the reduction of blood pressure was related to baseline plasma norepinephrine (p less than 0.05). The pressor response of systolic blood pressure to anger challenge (p less than 0.02) was blunted by relaxation therapy. These findings suggested that noradrenergic control of blood pressure was amplified during stress and relaxation therapy was effective in lowering blood pressure and neutralizing the response to "social stress" anger instigation.
Psychic effects of physical training and relaxation therapy after myocardial infarction.
The psychological impact of exercise training and relaxation therapy was investigated in 156 myocardial infarction patients. They were randomly assigned to either exercise plus relaxation and breathing therapy (Treatment A: n = 76) or exercise training only (Treatment B: n = 80). Patients in Treatment A improved on three out of eight psychological measurements (anxiety, well-being, feelings of invalidity). No change was demonstrable in Treatment B. The difference between the treatments was significant for wellbeing (p less than 0.005). Physical outcome, measured by exercise testing was positive in about half of the patients (Treatment A: 55%, Treatment B: 46%). A negative outcome occurred less in Treatment A (p less than 0.05). Training success was not associated with psychic benefit. The association differed for the two treatments. It was concluded that exercise training was effective for some but not for all cardiac patients, and that a psychic effect of exercise could not be demonstrated. Relaxation therapy enhanced physical and psychic outcome of rehabilitation.
[Results of the use of relaxation therapy in hypertension].
To assess the efficiency of relaxation therapy (RT) as part of the treatment for essential hypertension (EH), 100 male EH patients, aged 20 to 55 years, were repeatedly examined at 12 months' intervals, using clinical, psychological and psychophysiologic tests. The patients were divided into 2 groups: the main group received RT as autotraining (AT) or using biologic feedback devices, and the control group was not exposed to mental influences. Patients from the main group showed a more marked resting BP drop as well as a smaller and shorter hypertensive response to emotional stress, improved psychosocial status and psychologic adaptation, and better working capacity. A comparative five-year follow-up study of 90 patients was carried out to assess the value of RT for secondary EH prevention. The use of AT is associated with a slower progress of the disease, as compared to the controls, as evidenced by lower BP values, more limited growth of left-ventricular hypertrophy, and lesser neurotization as well as shorter EH-related temporary disability periods.
Relaxation therapy for essential hypertension: a Veterans Administration Outpatient study.
Twenty-nine patients who had been treated with antihypertensive medication for at least the preceding 6 months were randomly assigned to (1) therapist-conducted, face-to-face progressive, deep-muscle relaxation training for 10 weekly sessions, or (2) progressive deep-muscle relaxation therapy conducted mainly by home use of audio cassettes, or (3) nonspecific individual psychotherapy for 10 weekly sessions. No differences between the groups were found immediately after therapy; however, the therapist-conducted relaxation therapy group showed the greatest changes: -17.8 mm Hg systolic, -9.7 mm Hg diastolic at 6 months follow-up. Some significant trends in results among the three therapists were also found. No correlation existed between blood pressure changes and changes in dopamine-beta-hydroxylase (DbH) levels.
Relaxation therapy for tension headache in the elderly: a prospective study.
We evaluated the effects of an 8-week progressive muscle-relaxation therapy regimen on the headache activity of 10 elderly tension-headache subjects. Posttreatment assessment at 3 months revealed significant decreases in overall headache activity (50% or greater) in 7 subjects. Significant clinical or statistical prepost differences, or both, were also found for the number of headache-free days, peak headache activity, and medication index. This is the first prospective study of tension headache in an elderly population, and, unlike previous retrospective studies, it suggests that relaxation therapy may be an effective intervention in the treatment of such headaches.
Relaxation therapy and high blood pressure.
Thirty-one patients receiving medical treatment for essential hypertension were randomly distributed into three groups: (1) relaxation therapy, (2) nonspecific therapy, and (3) medical treatment only. The nonspecific therapy group spent the same amount of time with the therapists as the relaxation group but was not given a specific therapy. Blood pressures were measured at a different time and in a different place from the behavioral treatments. The relaxation therapy group showed a significant reduction in blood pressure postreatment compared with the nonspecific therapy and medical treatment only groups, even when those patients whose medication was increased were excluded from the data analysis. At follow-up six months post-treatment, the relaxation group showed a slight decrement in treatment effects, while both the nonspecific therapy and medical treatment only groups showed continued improvement; thus, there was not a significant difference between groups.
Effects of relaxation therapy and hypnotizability in chronic urticaria.
The therapeutic results of hypnosis with relaxation therapy were evaluated in 15 patients with chronic urticaria of 7.8 years' average duration. Compared with baseline and control session values, the hypnosis session provided relief of pruritus as measured by three self-report parameters. There was no change in the number of hives. All subjects were given a standard test for hypnotizability. Assuming that the results were not biased by their preceding relaxation sessions, we determined that six subjects were hypnotizable and nine were nonhypnotizable. Subjects in both groups improved symptomatically, but hypnotizable subjects had fewer hives and became more symptomatic during the control (testing and history taking) session. Hypnotizable subjects also more frequently related stress as a causative factor. At a follow-up examination five to 14 months after the completion of the experimental sessions, six patients were free of hives and an additional seven reported improvement.
Cardiac events after myocardial infarction: possible effect of relaxation therapy.
Comprehensive cardiac rehabilitation aims primarily at improving quality of life, but an effect on morbidity and mortality may also be expected, especially when changes in behaviour and life-style are induced. The value of relaxation therapy and exercise training in post myocardial infarction (MI) patients was investigated. A group of 90 post MI patients were randomly assigned to either exercise training plus individual relaxation and breathing therapy (treatment A), or exercise training only (treatment B). The occurrence of cardiac events, consisting of cardiac death and of readmission to hospital for unstable angina pectoris, coronary artery bypass grafting (CABG) or recurrent infarction, differed significantly for the two treatment groups in the 2-3 years after infarction. Seven out of 42 patients in treatment group A (17%) experienced a cardiac event, in contrast to 17 out of 46 (37%) patients in treatment group B, (P = 0.05, two-tailed). The results suggest that a combination of a behavioural treatment such as relaxation therapy with exercise training is more favourable for the long-term outcome after myocardial infarction than is exercise training alone.
Relaxation therapy reduces anxiety in child and adolescent psychiatric patients.
The immediate effects of relaxation therapy (RT) were assessed in 40 hospitalized children and adolescents with diagnoses of adjustment disorder and depression. These effects were assessed using a within subjects pre-test/post-test design and by comparison with a control group of 20 depressed and adjustment disorder patients who watched a 1-h relaxing videotape. The 1-h RT class consisted of yoga exercise, a brief massage and progressive muscle relaxation. Decreases were noted in both self-reported anxiety and in anxious behavior and fidgeting as well as increases in positive affect in the RT but not the video group. In addition, adjustment disorder patients and a third of the depressed patients showed decreases in cortisol levels following RT, while no changes were noted in the video group. Thus, both diagnostic groups appeared to benefit from the RT class.
Ear-acupuncture relaxation therapy in alcoholics. Report on a follow-up survey.
Ninety-five out of 190 alcoholics treated in 1977 by ear-acupuncture relaxation therapy were selected for a follow-up survey. Sixty-two replied to our letters and were interviewed (by C.F.). Sixteen (25.8%) said that they had maintained total sobriety for over 12 months, while 54 (87%) said that their life-style, drinking pattern and physical and mental health had improved. thus, a significant percentage had been helped to improved health and to a changed way of life.
Behavioral and physiological effects of a beta blocker and relaxation therapy on mild hypertensives.
In this industrial-based study we compared the blood pressure (BP)-lowering effectiveness of relaxation, a beta blocker, and the combined use of these two treatments in 47 untreated, mildly hypertensive blue collar steel workers. Using a randomized two by two factorial design, patients received either nadolol or placebo drug daily, and either a relaxation training or an education program, each lasting 8 weeks. A pre-intervention and post-intervention stress test measured response of heart rate and BP to mental and physical tasks. BP assessments were done at baseline, post-intervention, 1 month, and 3 month follow-up. Change in several self-report measures was determined. Results showed that beta blocker was more effective in lowering BP than placebo, but relaxation was not more effective in lowering BP than health education. The combined effect of beta blocker and relaxation was not superior to beta blocker alone. Compliance with relaxation practice was not superior to compliance with medication. We conclude that pharmacologic treatment is superior to the relaxation therapy tested.
Effect of relaxation therapy on post-myocardial infarction patients' rehabilitation.
This research measured the physical and psychosocial effects of the practice of Benson's relaxation technique by male postmyocardial infarction patients enrolled in a cardiac rehabilitation program and determined if the patient's behavioral style (Type A or Type B) was related to the outcomes. Twenty-seven subjects completed the experimental condition; 30, the control condition. Outcome measures included blood pressure, heart rate, aerobic conditioning level (MET level), and psychosocial functioning, as measured by the Sickness Impact Profile. Repeated measures analysis of variance was used to determine if relaxation therapy and/or behavior style had an effect on measures of the effectiveness of cardiac rehabilitation. The practice of relaxation was found to have a significant effect on diastolic blood pressure. Behavior style was unrelated to the outcome measures.
