项目摘要

Spasticity is defined as hypertonicity due to dysfunction of central nervous system such as cerebro-vascular accident. Activities of daily living such as eating and gait are affected by spasticity, resulting in disorders of voluntary movement.In clinical field, spasticity has been evaluated by subjective impression of the examiner based on the characteristics of resistance to passive stretching. However, this clinical evaluation method for spasticity has several limitations, such as being qualitative and poor reliability. Furthermore, the scientific evidence regarding the substantial characteristics of spasticity and the effects of intervention in rehabilitation is not clear.This study aimed to develop a clinical evaluation method for spasticity using a handheld measurement device. The handheld measurement device consisted of a palmer plate with pressure sensor, belt, and an analogue output. Spasticity was measured through the detection of the analogue signals from the handheld measurement device attached to the palmer aspect of examiner during passive stretch. Analogue signals from handheld measurement device were converted to digital signals at 1kHz sampling frequency. The converted digital signals were analyzed by using a bio-information analyzing software (Kissei-comtec, BIMUTAS II). The characteristics of spasticity were analyzed based on the amplitude and waveform.From the above pilot study, it was thought that this handheld measurement device was a useful clinical tool for the measurement of spasticity.

痉挛定义为由于中枢神经系统功能障碍（例如脑血管事故）引起的高渗性。饮食和步态等日常生活的活动受到痉挛的影响，导致自愿运动的疾病。在临床领域，已经根据对被动拉伸的抗性的特征来评估检查者的主观印象。但是，这种痉挛的临床评估方法具有多种局限性，例如定性和可靠性差。此外，尚不清楚有关痉挛的实质特征和干预措施的影响的科学证据。这项研究旨在使用手持式测量设备开发一种临床评估方法来痉挛。手持式测量设备由带压力传感器，皮带和模拟输出的Palmer板组成。通过在被动拉伸期间从检查者帕尔默（Palmer）方面附着的手持测量设备中检测模拟信号来测量痉挛。以1KHz采样频率将手持测量设备的模拟信号转换为数字信号。使用生物信息分析软件（Kissei-Comtec，Bimutas II）分析了转换后的数字信号。根据上述试验研究，认为该手持式测量装置是测量痉挛的有用临床工具，对痉挛的特征进行了分析。
