脊髓病手功能评测系统的开发及软件实现

Development of Myelopathy-Hand Function Evaluation System and Software Implementation

目的基于数据手套(Date-glove)技术结合计算机编程软件,开发脊髓病手功能评测系统(MFS)。方法分别选取确诊脊髓型颈椎病(CSM)患者及健康成年人各20例作为研究对象,应用Wise Glove数据手套获取10 s手屈伸测试(GRT)掌指关节的活动动态信号,以Visual C++为编程工具编写计算机软件模拟掌指关节的角度变化。结果 CSM组左手10 s GRT平均15.20次/10 s,右手平均15.45次/10 s,健康对照组左手平均23.42次/10 s,右手平均23.63次/10 s,两组同侧10 s GRT测试结果差异有统计学意义(P<0.05),CSM患者存在不同程度的手部功能下降。结论 MFS具有集成度高、无创、定量、可靠、操作简便等特点,并首次采用Date-glove技术对脊髓病手功能进行量化分析。

Objective To develop a MFS （Myelopathy-Hand Function Evaluation System） in combination with computer programming based on the data glove technology. Methods Altogether 20 confirmed CSM （Cervical Spondylotic Myelopathy） patients and 20 healthy volunteers were selected respectively in this study. With deployment of the WiseGlove data glove, motion signals of the metacarpophalangeal joint during 10-s GRT （Grip and Release Test） were acquire dand processed by the computer software based on VC＋＋programming to simulate the angular changes of the metacarpophalangeal joint. Results The average 10-s GRT results of the left and right hands in CSM Group were 15.20 times/10 s and 15.45 times/10 s respectively in contrast with 23.42 times/10 s and 23.63 times/10 s in Control Group. Statistically significant differences existed in the 10-s GRT results of the same-sided hands between two groups （P〈0.05）. Hand functions were deteriorated to various degrees in patients with CSM. Conclusion With the ifrst ever adoption of the data glove technology, MFS had demonstrated its high-integration, noninvasive, quantitative, reliable and easy-to-operate features in quantitative analysis of myelopathy-hand functions.
