Upper Limb Spasticity Evaluation Based on Stretch Reflex Threshold:Method, Device, Validity and Reliability
摘要
Abstract
Clinical methods for spasticity evaluation are criticized as subjective,and their validity and reliability remain to improve. This study is to present a new evaluation method for accurate and reliable evaluation of spasticity based on a stretch reflex threshold which is obtained from the acceleration and angle data. A corresponding device is designed to test the validity and reliability of the stretch reflex threshold in spasticity assessment, and further study is conducted to discuss the validity and reliability of acceleration mean variance(AMV).Spasticity is evaluated in 22 subjects with upper limb spasticity using the constructed portable device and the modified Ashworth scale (MAS) by four evaluators. The results of correlation analysis show that there is a strong negative correlation (r=?0.831 ～ ?0.953, P <0.05) between MAS and the stretch reflex threshold. Also,the correlation coefficient between the MAS and AMV is(r=0.665～0.900, P < 0.05). Their test-retest reliabilities are (r = 0.890 ～ 0.962, P < 0.05) and (r = 0.632 ～ 0.928, P < 0.05). These results demonstrate that the method and device may provide a quantitative and practical way for spasticity measurement.关键词
