有人认为，由于其解剖连接，紧腘绳肌可能是一种代偿机制，为臀肌无力和骶髂关节功能障碍患者提供骶髂关节（SI）稳定性。本研究的目的是确定骶髂关节功能障碍受试者的腘绳肌长度和臀肌力量之间的关系。共有159名年龄在20至65岁之间的患有和不患有腰痛（LBP）的受试者参加了这项研究。受试者被分为三组：LBP没有SIJ参与（n=53）; SIJ功能障碍的背痛（n=53）;和没有腰痛（n=53）。测量所有受试者的腘绳肌长度和臀肌力量。SI关节功能障碍受试者（66%）中臀肌无力的人数显著（P=0.02）高于无SI关节功能障碍的LBP受试者（34%）。在汇总数据中，SI关节功能障碍受试者和无SI受累的背痛受试者之间的腘绳肌长度无显著差异（P=0.31）。然而，在SI关节功能障碍的受试者中，与没有臀肌无力的个体（平均值= 165 +/- 10度）相比，臀肌无力的受试者的腘绳肌长度（平均值= 158 +/-11度）显著缩短（P=0.02）。其他各组中有无臀肌无力个体的腘绳肌长度差异无统计学意义（P>0.05）。总之，SI关节功能障碍受试者的腘绳肌紧绷可能与臀肌无力有关。本研究中发现的腘绳肌长度的轻微差异，尽管具有统计学意义，但不足以得出任何明确的结论。腘绳肌在骶髂关节稳定性中的作用有待进一步研究。
It has been suggested that tight hamstring muscle, due to its anatomical connections, could be a compensatory mechanism for providing sacroiliac (SI) joint stability in patients with gluteal muscle weakness and SIJ dysfunction. The purpose of this study was to determine the relationship between hamstring muscle length and gluteal muscle strength in subjects with sacroiliac joint dysfunction. A total of 159 subjects with and without low back pain (LBP) between the ages of 20 and 65 years participate in the study. Subjects were categorized into three groups: LBP without SIJ involvement (n=53); back pain with SIJ dysfunction (n=53); and no low back pain (n=53). Hamstring muscle length and gluteal muscle strength were measured in all subjects. The number of individuals with gluteal weakness was significantly (P=0.02) higher in subjects with SI joint dysfunction (66%) compared to those with LBP without SI joint dysfunctions (34%). In pooled data, there was no significant difference (P=0.31) in hamstring muscle length between subjects with SI joint dysfunction and those with back pain without SI involvement. In subjects with SI joint dysfunction, however, those with gluteal muscle weakness had significantly (P=0.02) shorter hamstring muscle length (mean= 158 +/- 11 degrees) compared to individuals without gluteal weakness (mean= 165 +/- 10 degrees). There was no statistically significant difference (P>0.05) in hamstring muscle length between individuals with and without gluteal muscle weakness in other groups. In conclusion, hamstring tightness in subjects with SI joint dysfunction could be related to gluteal muscle weakness. The slight difference in hamstring muscle length found in this study, although statistically significant, was not sufficient for making any definite conclusions. Further studies are needed to establish the role of hamstring muscle in SI joint stability.
