ABSTRACT

PURPOSE: This study aimed to compare the effects of pain level, lower back pain dysfunction level, psychosocial level, hip abductor strength (HAS), number of positive lumbar instability tests, and dynamic balance (DB) by applying lumbar stabilization exercises according to the presence or absence of gluteus medius muscle weakness in chronic lower back pain (CLBP) patients with lumbar instability. METHODS: Thirty-five CLBP patients with lumbar instability were divided into the gluteus medius weakness (n = 18) and gluteus medius non-weakened (n = 17) groups using the gluteus medius manual muscle test. Intervention applied conservative physical therapy and lumbar stabilization exercises to both groups that lasted three times a week for four weeks. To compare the intervention effects, the quadruple visual analog scale (QVAS), the Korean version of the Oswestry disability index (K-ODI), fear-avoidance beliefs questionnaire (FABQ), HAS, lumbar instability tests positive response counter (LIC), and DB were measured. RESULTS: Significant differences were shown for QVAS, K-ODI, FABQ, HAS, LIC, and DB for both groups pre- and post-intervention (p < .05). Compared to the gluteus medius weakness group, the gluteus medius non-weakened group showed a significant difference (p < .05) in the changes in QVAS, K-ODI, FABQ-W, FABQ-total, and HAS. CONCLUSION: In CLBP patients with lumbar instability, having gluteus medius weakness was less effective in improving lumbar stabilization exercise than gluteus medius non-weakness regarding pain level, lower back pain dysfunction level, psychosocial level excluding physical activity, and hip abductor strength. Therefore, additional gluteus medius strengthening exercises are necessary for patients with lumbar instability and gluteus medius muscle weakness.
