摘要
目的研究表面肌电联合等速测试评定肌痉挛的作用。方法16例脑卒中患者(观察组)和16例正常人(对照组)参加本项研究,采用表面肌电测试训练系统联合等速测试训练仪,进行踝关节等速被动运动时腓肠肌表面肌电的动态测试。患者痉挛下肢改良Ashworth评分≧1+级,设定踝关节被动运动时测试角速度分别为10°/s、30°/s,每一角速度下重复关节屈伸动作5次,组间休息1min。分别测定两组踝关节被动活动过程中腓肠肌表面肌电均方根值(RMS)、峰阻矩(PT)和峰阻矩/体重比(PT/BW),并进行重复测试,二次测试间休息3min。结果前后两次测试数据的差异无显著性(P>0.05)。角速度为分别10°/s、30°/s时,比较观察组与对照组的RMS、PT,、PT/BW指标,除30°/s时的RMS值组间比较无显著性差异外(P>0.05),其余均差异有显著性(P<0.05﹚。10°/s、30°/s两种角速度下观察组间及对照组间比较,除对照组组间PT,、PT/BW比较差异无显著性外(P>0.05),其余数据各组间比较均有显著差异(P<0.05)。结论表面肌电、等速测试评定肌痉挛有良好的信度,稳定性较好,可联合应用作为评定肌痉挛的量化指标。
【Objective】To assess the spasticity of muscle in stroke patients with the surface electromyography （sEMG） and isokinetic assessment. 【Methods】In this study 16 stroke patients and 16 health persons were involved. All subjects took continuous passive motion of ankle at the angular velocity at 10°/s and 30°/s for 5 repeated times,after 3 minutes＇rest, the same procedure was repeated. The affected limb of the patients and the same side of the health persons were taken for the test. The RMS （root mean square） value of gastrocnemius surface electromyographic signal, peak torque and peak torque/body weight of isokinetic assessment were recorded. 【Results】No significant differences were found in all subjects＇data between the first test and the second test （P 0.05）. At the angular velocity of 30°/s, the RMS value of gastrocnemius showed no significant difference between the observation group and the control group （P 0.05）, while all the remaining data of the two groups showed significant difference （P 0.05）. 【Conclusion】Surface electromyography and isokinetic assessment can be used to estimate muscle spasticity of stroke patients in clinic, and both are reliable.
