Yoga versus non-standard care for schizophrenia

Area of Science:

• Psychiatry and Mental Health
• Complementary and Alternative Medicine
• Clinical Trials and Evidence Synthesis

Background:

• Yoga, originating in India, is recognized globally as a practice for relaxation and exercise.
• Its potential as an alternative or adjunctive treatment for schizophrenia has garnered interest.
• This review systematically evaluates yoga's efficacy in schizophrenia management.

Purpose of the Study:

• To systematically assess the effects of yoga compared to non-standard care for individuals with schizophrenia.
• To synthesize evidence from randomized controlled trials (RCTs) on yoga's impact on schizophrenia outcomes.

Main Methods:

• A comprehensive search of specialized trials registers and databases (e.g., MEDLINE, PubMed) was conducted.
• Six randomized controlled trials (RCTs) involving 586 participants with schizophrenia were included.
• Data analysis involved calculating risk ratios and mean differences, with assessment of heterogeneity and risk of bias.

Main Results:

• Yoga demonstrated a statistically significant reduction in participants leaving the study early (medium quality evidence).
• No significant differences were observed between yoga and non-standard care (primarily aerobic exercise) for mental state, social functioning, or quality of life.
• Limited data on adverse effects showed no events in either group; many outcomes, including relapse and cognition, were not reported.

Conclusions:

• Current evidence suggests minimal differences between yoga and non-standard exercise comparators for schizophrenia.
• The available evidence is of low to moderate quality, based on limited sample sizes and short-term follow-up.
• The findings are insufficient to conclude that yoga is superior or inferior to non-standard care for managing schizophrenia.
