Positive antidepressant effects of generic yoga in depressive out-patients: A comparative study.

CONTEXT

Therapeutic effects in depression of yoga adopted from different schools have been demonstrated. The efficacy of a generic module of yoga on depressed patients has not yet been tested in the literature.

AIMS

The study was aimed to compare the therapeutic effect of a generic yoga module with antidepressant drugs in non-suicidal out-patients of major depression attending a psychiatric hospital.

SETTINGS AND DESIGN

The study was outpatient-based using an open-labeled design.

MATERIALS AND METHODS

A total of 137 out-patients of depressive disorders received one of the three treatments as they chose - yoga-only, drugs-only or both. The yoga was taught by a trained yoga physician for over a month in spaced sessions totaling at least 12. Patients were assessed before treatment, after 1 and 3 months on depression and Clinical Global Impression Scales. Out of 137, 58 patients completed the study period with all assessments.

RESULTS

Patients in the three arms of treatment were comparable on demographic and clinical variables. Patients in all three arms of treatment obtained a reduction in depression scores as well as clinical severity. However, both yoga groups (with or without drugs) were significantly better than the drugs-only group. Higher proportion of patients remitted in the yoga groups compared with the drugs-only group. No untoward events were spontaneously reported in the yoga-treated patients.

CONCLUSION

Within the limitations of this study, it can be concluded that the findings support a case for prescribing yoga as taught in the study in depressive non-suicidal out-patients.
