Dysfunction of spinal stability seems to be one of the causes of low back pain (LBP). It is thought that a large number of muscles have a role in spinal stability including the pelvic floor muscle (PFM). The purpose of this study was to investigate the effect of PFM exercise in the treatment of chronic LBP. After ethical approval, a randomized controlled clinical trial was carried out on 20 women with chronic LBP. Patients were randomly allocated into two groups: an experimental and a control group. The control group was given routine treatment including electrotherapy and general exercises; and the experimental group received routine treatment and additional PFM exercise. Pain intensity, functional disability and PFM strength and endurance were measured before, immediately after intervention and at 3 months follow-up. In both groups pain and functional disability were significantly reduced following treatment (p<0.01), but no significant difference was found between the two groups (p>0.05). All measurements were improved in both groups (p<0.01) although patients in the experimental group showed greater improvement in PFM strength and endurance (p<0.01). It seems that the PFM exercise combined with routine treatment was not superior to routine treatment alone in patients with chronic LBP.
脊柱稳定性功能障碍似乎是腰痛（LBP）的病因之一。人们认为大量肌肉对脊柱稳定性发挥作用，其中包括盆底肌（PFM）。本研究旨在探讨盆底肌锻炼对慢性腰痛治疗的效果。经伦理批准后，对20名慢性腰痛女性患者进行了一项随机对照临床试验。患者被随机分为两组：实验组和对照组。对照组接受包括电疗和一般锻炼的常规治疗；实验组接受常规治疗并额外进行盆底肌锻炼。在干预前、干预后即刻以及随访3个月时测量疼痛强度、功能障碍以及盆底肌力量和耐力。两组治疗后疼痛和功能障碍均显著减轻（p<0.01），但两组之间无显著差异（p>0.05）。两组的所有测量指标均有改善（p<0.01），尽管实验组患者的盆底肌力量和耐力改善更大（p<0.01）。对于慢性腰痛患者，盆底肌锻炼联合常规治疗似乎并不优于单纯常规治疗。
