To examine the reliability of clinical techniques for testing hip abductor and adductor muscle performance.
Repeated measures.
Academic laboratory.
A sample of 21 healthy subjects (12 men, 9 women) between 22 and 31 years of age.
Not applicable.
Reliability of repeated measures was estimated by calculating intraclass correlation coefficients. Torque production capability was calculated by multiplying force output obtained with a hand-held dynamometer by the length of the resistance lever arm.
The reliability of abduction testing was greatest in the long-lever condition. Adduction test reliability was greatest in the long-lever condition with bench stabilization. The maximal hip abduction torque tested in the long-lever position was significantly greater (t(20)=9.21, P<.001) than that in the short-lever position. The maximal hip adduction torque occurred using a long lever for resistance application and a bench to stabilize the nontest leg (F(1,20)=15.64, P=.001).
Muscle performance testing of hip abductors and adductors with a hand-held dynamometer can be performed with good to excellent intratester and intertester reliability. Hip abduction testing is best performed with a long lever. Hip adduction is best performed with a long lever and a bench to stabilize the nontest extremity.
检验用于测试髋外展肌和内收肌性能的临床技术的可靠性。
重复测量。
学术实验室。
21名年龄在22至31岁之间的健康受试者样本（12名男性，9名女性）。
不适用。
通过计算组内相关系数来估计重复测量的可靠性。扭矩产生能力通过将手持式测力计获得的力输出乘以阻力杠杆臂的长度来计算。
在外展测试中，长杠杆条件下的可靠性最高。在内收测试中，使用长杠杆并借助长椅稳定身体时可靠性最高。长杠杆位置测试的最大髋外展扭矩显著大于短杠杆位置（t(20)=9.21，P<.001）。使用长杠杆施加阻力并借助长椅稳定非测试腿时出现最大髋内收扭矩（F(1,20)=15.64，P=.001）。
使用手持式测力计对髋外展肌和内收肌进行肌肉性能测试，测试者内和测试者间的可靠性良好至优秀。髋外展测试最好使用长杠杆进行。髋内收测试最好使用长杠杆并借助长椅稳定非测试肢体进行。
