OBJECTIVES

Yoga based lifestyle modifications have been earlier shown to be beneficial in coronary artery disease in a small number of patients. We evaluated the role of lifestyle modification based on Yoga techniques, stress management and dietary modifications in retardation of coronary artery disease.

 METHODS:

This prospective, controlled, open trial included angiographically proven coronary artery disease patients (71 patients in study group and 42 patients in control group). They were assessed clinically, by biochemical parameters, stress myocardial perfusion and function studies and coronary angiography and on psychological parameters. The study group patients were given a family based Yoga Programme which included, control of risk factors, dietary modifications and stress management for a period of one year. The patients were assessed at baseline, at frequent intervals and at the end of one year.

RESULTS:

 At the end of one year of yoga training, statistical significant changes (P<0.05) were found in serum total cholesterol (reduction by 23.3% in study group patients as compared to 4.4% in controls); serum LDL cholesterol (reduction of 26% in study group patients as compared to 2.6% in the control group), regression of disease (43.7% of study group patients v/s 31% control group on MPI and 70.4% of study group v/s 28% of control group on angiography) arrest of progression (46.5% study group v/s 33.3% control group on MPI) and progression (9.9% of study group vs 35.7% of controls on MPI, 29.6% of study group v/s 60.0% of controls on angiography). At the end of the study improvement in anxiety scores was concordant with the improvement seen in the MPI. No untoward effects of the therapy were observed.

CONCLUSION:

Yoga based lifestyle modifications help in regression of coronary lesions and in improving myocardial perfusion. This is translated into clinical benefits and symptomatic improvement.

Adult asthmatics, ranging from 19 to 52 years from an asthma and allergy clinic in a university setting volunteered to participate in the study. The 17 students were randomly divided into yoga (9 subjects) and nonyoga control (8 subjects) groups. The yoga group was taught a set of breathing and relaxation techniques including breath slowing exercises (pranayama), physical postures (yogasanas), and meditation. Yoga techniques were taught at the university health center, three times a week for 16 weeks. All the subjects in both groups maintained daily symptom and medication diaries, collected A.M. and P.M. peak flow readings, and completed weekly questionnaires. Spirometry was performed on each subject every week.

Analysis of the data showed that the subjects in the yoga group reported a significant degree of relaxation, positive attitude, and better yoga exercise tolerance. There was also a tendency toward lesser usage of beta adrenergic inhalers. The pulmonary functions did not vary significantly between yoga and control groups. Yoga techniques seem beneficial as an adjunct to the medical management of asthma.

BACKGROUND:

Chronic low back pain is a common problem that has only modestly effective treatment options.

OBJECTIVE:

To determine whether yoga is more effective than conventional therapeutic exercise or a self-care book for patients with chronic low back pain.

DESIGN:

Randomized, controlled trial.

SETTING:

A nonprofit, integrated health care system.

 PATIENTS:

 101 adults with chronic low back pain.

INTERVENTION:

12-week sessions of yoga or conventional therapeutic exercise classes or a self-care book.

MEASUREMENTS:

Primary outcomes were back-related functional status (modified 24-point Roland Disability Scale) and “bothersomeness” of pain (11-point numerical scale). The primary time point was 12 weeks. Clinically significant change was considered to be 2.5 points on the functional status scale and 1.5 points on the bothersomeness scale. Secondary outcomes were days of restricted activity, general health status, and medication use.

RESULTS:

After adjustment for baseline values, back-related function in the yoga group was superior to the book and exercise groups at 12 weeks (yoga vs. book: mean difference, -3.4 [95% CI, -5.1 to – 1.6] [P < 0.001]; yoga vs. exercise: mean difference, -1.8 [CI, -3.5 to – 0.1] [P = 0.034]). No significant differences in symptom bothersomeness were found between any 2 groups at 12 weeks; at 26 weeks, the yoga group was superior to the book group with respect to this measure (mean difference, -2.2 [CI, -3.2 to – 1.2]; P < 0.001). At 26 weeks, back-related function in the yoga group was superior to the book group (mean difference, -3.6 [CI, -5.4 to – 1.8]; P < 0.001).

LIMITATIONS:

Participants in this study were followed for only 26 weeks after randomization. Only 1 instructor delivered each intervention.

CONCLUSIONS:

Yoga was more effective than a self-care book for improving function and reducing chronic low back pain, and the benefits persisted for at least several months.

Forty six young asthmatics with a history of childhood asthma were admitted for yoga training. Effects of training on resting pulmonary functions, exercise capacity, and exercise-induced bronchial lability index were measured. Yoga training resulted in a significant increase in pulmonary function and exercise capacity. A follow-up study spanning two years showed a good response with reduced symptom score and drug requirements in these subjects. It is concluded that yoga training is beneficial for young asthmatics.
