Yoga for chronic non-specific low back pain.

Area of Science:

• Evidence-based medicine
• Complementary and alternative medicine
• Musculoskeletal health

Background:

• Non-specific low back pain is a prevalent, disabling condition.
• Current guidelines advocate exercise therapy for chronic low back pain.
• Yoga, a mind-body exercise, is explored for its efficacy in managing this condition.

Purpose of the Study:

• To assess the benefits and harms of yoga for chronic non-specific low back pain.
• Comparisons include sham yoga, no treatment, minimal intervention, or active treatments.
• Outcomes focus on pain, function, quality of life, and adverse events.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials.
• Searched Cochrane databases without language or publication restrictions up to August 31, 2021.
• Included 21 trials involving 2223 participants, assessing various yoga styles against different control groups.

Main Results:

• Low-certainty evidence suggests yoga provides small, clinically unimportant improvements in back-specific function and pain compared to no exercise.
• Moderate-certainty evidence indicates probable small improvements in physical and mental quality of life.
• Yoga was associated with an increased risk of adverse events, primarily increased back pain, compared to no exercise.

Conclusions:

• Yoga yields small, clinically unimportant improvements in back pain and function compared to no exercise.
• Effectiveness of yoga versus other back-focused exercises for function, pain, and quality of life remains uncertain.
• Increased adverse events are noted with yoga compared to no exercise; risk is similar to other exercises.
