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.

痉挛是指由于中枢神经系统功能障碍如血管意外等引起的高张力状态。痉挛状态会影响进食、步态等日常生活活动，导致自主运动障碍，临床上主要根据检查者对被动牵拉的抵抗力特点，通过主观印象来评价痉挛状态。然而，这种痉挛状态的临床评估方法有一些局限性，如定性和可靠性差。此外，有关痉挛的实质特征和康复干预效果的科学证据尚不清楚，本研究旨在开发一种使用手持测量设备的痉挛临床评估方法。手持式测量装置由带压力传感器的压板、皮带和模拟输出组成。在被动伸展期间，通过检测附在检查者手掌侧的手持式测量设备的模拟信号来测量痉挛。手持测量装置的模拟信号以1 kHz的采样频率转换为数字信号。通过使用生物信息分析软件（Kissei-comtec，BIMUTAS II）分析转换的数字信号。从幅度和波形方面分析了痉挛的特征，通过上述初步研究，认为该手持式测量装置是一种有用的痉挛测量临床工具。
