To evaluate the reliability of maximal static strength measurements of five arm muscle groups and of strength ratios (paretic/non-paretic) in subjects with poststroke hemiparesis.
The generalizability theory was used to estimate the reliability coefficients and standard errors of measurement of maximal strength for various combinations of trials and sessions and of the strength ratios for one and two sessions. Grip maximal voluntary force and/or maximal voluntary torques exerted by flexor and extensor muscles at both the elbow and shoulder joints were measured in 17 subjects with poststroke hemiparesis. Multiple trials were performed by subjects during two sessions.
Rehabilitation centre.
A convenience sample of 17 subjects with poststroke hemiparesis.
The reliability coefficients for the strength measurements were in the range of 0.81-0.97 with standard errors of measurement accounting for 4% to 20% of the group means. For the strength ratios, the coefficients of generalizability ranged from 0.76 to 0.95 with standard errors of measurement equal to 6% to 19% of the group means.
The maximal strength measurements of the arms in subjects with hemiparesis are reliable. The strength ratios are also reliable and can be used to quantify strength impairment.
评估中风后偏瘫患者五个手臂肌肉群最大静态力量测量值及力量比值（患侧/健侧）的可靠性。
采用概化理论来估计不同试验和测试组合下最大力量测量值的可靠性系数和测量标准误，以及一至两个测试阶段力量比值的可靠性系数和测量标准误。对17名中风后偏瘫患者测量了握力最大随意力和/或屈肌与伸肌在肘关节和肩关节处施加的最大随意扭矩。受试者在两个测试阶段进行了多次试验。
康复中心。
17名中风后偏瘫患者的便利样本。
力量测量的可靠性系数在0.81至0.97之间，测量标准误占组均值的4%至20%。对于力量比值，概化系数在0.76至0.95之间，测量标准误等于组均值的6%至19%。
偏瘫患者手臂的最大力量测量是可靠的。力量比值也可靠，可用于量化力量损伤。
