Altered Trunk Muscles May Cause Back Pain.

Using electromyography (EMG), researchers measured trunk muscle activity during lifting among 25 patients with recurrent low back pain (but without current back pain) and 20 asymptomatic individuals. The data show differences in the activity of several trunk muscles (transversus abdominis/internal abdominal oblique and multifidus) during lifting between the two groups. This suggests that patients with a history of back pain may benefit from specific rehabilitation exercises to address these issues. Journal of Electromyography and Kinesiology, February 2018
