Lumbar flexion-relaxation is a well-known phenomenon that can reliably be seen in normal participants, but not in most chronic low back pain (CLBP) participants. No earlier studies have investigated any specific clinical intervention designed to correct abnormal flexion-relaxation. The objective of this study was to evaluate the contribution of a surface EMG-assisted stretching (SEMGAS) biofeedback training protocol, within a functional restoration treatment program, on flexion range of motion (ROM) and erector spinae surface EMG (SEMG) during maximum voluntary flexion (MVF).
