Abstract

Background: This study was to investigate the effects of active stretching and stability exercise on piriformis muscle thickness and low back pain of male patients with chronic low back pain. Design: Randomized Controlled Trial. Methods: 45 male patients participated in this study. All subjects were randomly assigned. Subjects divided into 15 who underwent contract relaxation (CR) of the proprioceptive neuromuscular facilitation (PNF) to their hip joints, 15 who underwent a combination of isotonic (CI) of the PNF, and the rest 15 who underwent the two techniques (CR+CI). Real-time diagnostic ultrasound was used to measure thickness of the piriformis muscles. The visual analogue scale (VAS) was used to measure degrees of low back pain. A two-way repeated measures ANOVA was used to compare the average values. The SPSS 24.0 was used as the statistical program, and the significance level was set at .05. Results: The CR and the CR+CI groups had more decreased thickness of piriformis muscle when compared to the CI group. The CR+CI group had more decreased pain when compared to the CR and the CI groups. Conclusion: These results suggest that combination of stretching and stability exercise was effective on male patients with chronic low back pain showing limited hip medial rotation.
髋关节主动伸展运动和腰椎稳定运动对梨状肌厚度和腰痛的影响
背景:本研究旨在探讨主动拉伸和稳定性运动对男性慢性腰痛患者梨状肌厚度和腰痛的影响。设计:随机对照试验。方法:45例男性患者参与本研究。所有受试者均随机分配。被试分为15人接受髋关节本体感觉神经肌肉促进(PNF)的收缩松弛(CR), 15人接受PNF的等张(CI)组合,其余15人接受两种技术(CR+CI)。实时诊断超声测量梨状肌厚度。采用视觉模拟量表(VAS)评价腰痛程度。采用双向重复测量方差分析比较平均值。采用SPSS 24.0作为统计程序,显著性水平设为0.05。结果:与CI组相比,CR组和CR+CI组梨状肌厚度减少较多。与CR组和CI组相比,CR+CI组疼痛减轻更多。结论:这些结果表明伸展运动和稳定性运动相结合对髋关节内侧旋转受限的男性慢性腰痛患者有效。
