To develop a method for assessment of spasticity, in which the whole range of motion (ROM) at a wide variation of speeds is applied.
Cross-sectional design to study construct validity.
Research department affiliated with a rehabilitation hospital in The Netherlands.
Nine patients with complete spinal cord injury recruited from the rehabilitation hospital.
Not applicable.
Thirty to 45 stretches over the whole ROM were applied to the triceps surae muscle at varying velocities measuring from 30 degrees to 150 degrees/s. Electromyographic responses were measured in order to assess reflex excitability. The torque over the ankle joint was measured during the whole stretch. The angle and velocity at which the reflex was initiated was also determined.
The electromyographic responses increased significantly at increasing stretch velocities (P<.001). The applied maximum angles are reproducible (intraclass correlation coefficient, .81) and provide representative torque responses.
The assessment method of spasticity using full range passive movements provides objective outcomes. The angular velocity is responsible for an exponential increase in amplitude of the electromyographic response.
开发一种评估痉挛的方法，该方法适用于在广泛变化的速度下的全关节活动范围（ROM）。
采用横断面设计来研究结构效度。
荷兰一家康复医院附属的研究部门。
从康复医院招募的9名完全性脊髓损伤患者。
不适用。
在30度至150度/秒的不同速度下，对腓肠肌进行30至45次全ROM拉伸。测量肌电图反应以评估反射兴奋性。在整个拉伸过程中测量踝关节的扭矩。还确定了反射开始时的角度和速度。
随着拉伸速度的增加，肌电图反应显著增加（P<.001）。应用的最大角度具有可重复性（组内相关系数，.81），并提供代表性的扭矩反应。
使用全范围被动运动评估痉挛的方法可提供客观结果。角速度导致肌电图反应幅度呈指数增加。
