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.
