Provided is a spasticity measurement device making it possible to readily measure the degree of spasticity. A spasticity measurement device (10) is provided with a leg attachment tool (12) to which a lower leg attachment part (24) and a foot-accepting part (20) are linked so as to enable relative rotation. When the lower leg attachment part (24) and the foot-accepting part (20) are rotated in a relative fashion, the rotation is prohibited by a rotation prohibition device comprising a projection (88), an engagement recess (86), a helical compression spring (94), and other components, and the muscle contraction force acting in the direction of rotation thereof in this state is measured by a muscle contraction force measurement device constituted of a strain gauge (78), a data processing device (82), and other components. For this reason, rotating the foot-accepting part (20) and the lower leg attachment part (24) in a relative fashion causes rhythmic and repeated contraction in a test subject in whom spasticity of the lower leg (16) has been induced, while the lower leg flexor muscles remain fixed in a stretched state thus, using the muscle contraction force measurement device to measure the muscle contraction force acting in the direction of rotation of the foot-accepting part makes it possible to easily and quantitatively measure spasticity.本發明係提供一種可輕易測定攣縮度之痙攣性測定裝置。本發明之痙攣性測定裝置包含將小腿裝設部與腳部支承部連結成可相對旋轉之腳部裝設具,並可在該等小腿裝設部與腳部支承部已相對旋轉後,藉突起、卡合凹部、壓縮螺旋彈簧等所構成之旋轉禁止裝置而禁止其之旋轉,再藉應變測量計、資料處理裝置等所構成之肌肉收縮力測定裝置,在上述狀態下測定朝其旋轉方向作用之肌肉收縮力。因此,使腳部支承部與小腿裝設部相對旋轉而引發下肢之攣縮後之受測者可在固定於小腿屈肌肌群之長度已伸長之狀態下,被動進行節律之反覆收縮,故可藉肌肉收縮力測定裝置測定使腳部支承部朝旋轉方向作用之肌肉收縮力,而輕易且定量地測定攣縮度。10‧‧‧痙攣性測定裝置12‧‧‧腳部裝設具14‧‧‧腳部裝設具支持台16‧‧‧下肢18‧‧‧腳部20‧‧‧腳部支承部22‧‧‧小腿部24‧‧‧小腿裝設部26‧‧‧板狀構件28‧‧‧腳跟支承部30、32‧‧‧繫帶34‧‧‧固定側支持構件36‧‧‧旋動側支持構件38‧‧‧下肢上部固定具40‧‧‧基台42‧‧‧腳前端支持台44‧‧‧腳跟支持台46‧‧‧腳部支承部支持板48‧‧‧台部50‧‧‧軸承52‧‧‧突片54‧‧‧旋轉軸56‧‧‧旋臂支持部58‧‧‧滑輪支持部60‧‧‧第1旋臂62‧‧‧旋動軸64‧‧‧第2旋臂66‧‧‧旋轉軸68‧‧‧鋼線70‧‧‧轉輥72‧‧‧滑輪74‧‧‧手柄
