Between-group comparison of surface electromyography (EMG) and ground reaction force data of patients with sacroiliac joint (SIJ) pain and controls with and without pelvic belt application.

No significant differences in the muscle activities of SIJ patients and healthy controls were observed. Also, no differences were observed in the center of pressure (COP) data, derived from the pressure distribution data in one-leg stance. Values are given as mean values, standard deviation and p-values.Between-group comparison of surface electromyography (EMG) and ground reaction force data of patients with sacroiliac joint (SIJ) pain and controls with and without pelvic belt application.
