There are few studies of the therapeutic effects of long-term corset wearing in patients with chronic low back pain. The aim of this study was to evaluate the effects of long-term corset wearing on chronic low back pain and to examine the myoelectrical activities of the paravertebral muscles. Forty subjects with chronic low back pain were enrolled and randomly divided into two groups: a group wearing corsets for 6 months (CW) group and a group not wearing corsets (NW). The treatment effects were measured using the Japanese Orthopaedic Association (JOA) score. Muscle endurance was evaluated during the Biering-Sorensen test (S-test), and the degree of muscle fatigue was evaluated by the change in percent mean power frequency (%MPF) of the paravertebral muscles. Corset treatment for chronic low back pain improved low back pain and increased muscle endurance for a short period of time. Paravertebral muscle fatigue was not increased by long-term corset wearing for chronic low back pain, and weakening of the paravertebral muscles was not observed up to 6 months after the start of corset wearing.
关于长期佩戴束腹带对慢性下腰痛患者治疗效果的研究较少。本研究的目的是评估长期佩戴束腹带对慢性下腰痛的影响，并检测椎旁肌的肌电活动。招募了40名慢性下腰痛患者，随机分为两组：佩戴束腹带6个月的组（CW组）和不佩戴束腹带的组（NW组）。使用日本矫形外科学会（JOA）评分来衡量治疗效果。在 Biering-Sorensen 试验（S 试验）期间评估肌肉耐力，并通过椎旁肌平均功率频率百分比（%MPF）的变化来评估肌肉疲劳程度。束腹带治疗慢性下腰痛可在短时间内改善下腰痛并提高肌肉耐力。长期佩戴束腹带治疗慢性下腰痛不会增加椎旁肌疲劳，并且在开始佩戴束腹带后6个月内未观察到椎旁肌减弱。
