Examination of the flexion relaxation phenomenon in erector spinae muscles during short duration slumped sitting.
The purpose of this study was to examine the myoelectric activity of the erector spinae muscles of the back in order to determine if the flexion relaxation phenomenon occurs in seated forward flexion or slumped postures. ⋯ Examination of flexion relaxation during seated postures may provide insight into the association between low back pain and seated work.
