ABSTRACT

Purpose: The purpose of this study was to provide clinical information by comparing abdominal muscle activity and lumbopelvic rotation angle according to proprioceptive neuromuscular facilitation (PNF) lower pattern with pressure biofeedback unit or PNF lower pattern without pressure biofeedback unit in patients with chronic back pain. Methods: In this study, 20 patients with low back pain were instructed to perform PNF lower pattern with biofeedback unit and PNF lower pattern without biofeedback unit. Surface electromyography data were collected from the ipsilateral internal oblique (IIO), contralateral external oblique (CEO), ipsilateral rectus abdominal (IRA) muscles, and lumbopelvic rotation angle were measured using the motion analysis device. Results: The activation of all abdominal muscles was found greater in PNF lower pattern with biofeedback unit than that PNF lower pattern without biofeedback unit. The degree of lumbopelvic rotation angle in PNF lower pattern with biofeedback unit was found lower than that PNF lower pattern without biofeedback unit(p<0.05). Conclusion: The results of this study suggest that PNF lower pattern with biofeedback unit is effective in increasing abdominal muscle activity and decreasing unwanted lumbopelvic rotation in patients with chronic low back pain. Therefore, if you want to apply the PNF lower pattern to patients with chronic low back pain, it is considered effective to control the pelvis using the biofeedback unit.
