Effects of Baduanjin exercise on patients with chronic nonspecific low back pain and surface electromyography signs of erector spinal muscle: A randomized controlled trial

Chronic nonspecific low back pain (CNLBP) is a common disease usually with lower back muscle fatigue and injuries that may contribute to lumbar muscle imbalance and pain recurrence. This study aimed to examine the effectiveness of Baduanjin exercise on patients of CNLBP and to assess its impact on the surface electromyographic signals of the lumbar erector spinae muscle.
