摘　　要：目的:研究等速被动测试指标与改良Ashworth法在进行肌痉挛评定中的相关性。方法:对20例脑损伤后肌痉挛患者进行肌张力研究。使用改良Ashworth评定量表进行肌张力评定,然后采用Biodex System-3型等速测试仪,对痉挛下肢进行等速被动测试,设定膝关节测试运动角速度分别为30°/s,120°/s,180°/s,测定峰阻矩(peak torque,PT)和峰阻矩/体重比(peak torque/body weight,PT/BW)两个指标。采用Spearman法对上述两组结果进行相关分析。结果:所测两个指标分别与改良Ashworth评分进行相关分析,相关系数在0.633—0.962(P<0.01)。结论:在肌痉挛评定中,Ashworth法与等速测试法所得结果高度相关,在反映肌痉挛方面具有一致性。Objective：To study the correlation between isokinetic parameters and modified Ashworth scores in spasticity assessment. Method： Twenty patients of spasticity after hemiplegia were studied, The muscle tone were assessed with modified Ashworth spasticity scale（mASS） at first. Then the isokinetic dynamometer （Biodex System-3） was used to measure the resistance torque of knee joint at 30°/s,120°/s and 180°/s. Two parameters： peak torque （PT） and peak torque/body weight （PT/BW） were recorded. The Spearman correlation analysis was studied between two tests. Result： The correlation coefficient was 0.633-0.962 among mASS and PT and PT/BW during isokinetic tests（P〈0.01）. Conclusion： The isokinetic parameters were closely related with mASS. Both of them could represent the extent of spastieity.
