摘要这项随机对照研究评估了应变反应力(SCS)对髋关节肌肉的压痛点(TP)和力量的影响。方便样本包括49名志愿者(男15人，女34人；肢体98人)，年龄19~38岁，有髋关节无力和相应的TPS。视觉模拟评分用于评估疼痛；数字手持测功机用于评估力量。参与者被随机分为三个干预组：SCS组、运动组(EX)和SCS+EX组。所有的干预都在两周内进行了两次；在干预开始之前和之后，都测量了三次疼痛和力量。SCS组和SCS+EX组表现出更强的强度(p<；.001，双尾t检验)，当用单因素方差分析和Scheffé后置检验分析时，这一点显著大于EX组(p<；.001)。所有组在干预后2-4周疼痛减轻，力量增强(p<；.001)。结果支持SCS可减轻TP疼痛的假说，并证明SCS对力量有正向影响。
Abstract This randomized, controlled study assessed the effect of Strain Counterstrain (SCS) on tender points (TP) and strength of hip musculature. The convenience sample included 49 volunteers (15 men, 34 women; 98 limbs), aged 19-38 years, with hip weakness and corresponding TPs. A visual analog scale was used to assess pain; a digital handheld dynamometer was used to assess strength. Participants were randomly assigned to three intervention groups: SCS, Exercise (EX), and SCS+EX. All interventions were performed twice over two weeks; pain and strength were measured three times, both before and after intervention began. The SCS and SCS+EX groups demonstrated increased strength (p<.001, 2-tailed t-tests), which when analyzed with one-way ANOVA and Scheffé post-hoc tests was significantly greater than in the EX group (p<.001). All groups reported reduced pain and increased strength 2-4 weeks after intervention (p<.001). The results supported the hypothesis that SCS reduces TP pain and demonstrated that SCS positively affects strength.
