A kind of lower limb muscles spasm measuring device includes a pedestal unit, a power sensing element and a speed sensitive element. The pedestal unit has the pedestal of contact what patient's lower limb and one opposite what base motions and can provide the force seat that a clinical staff exerts a force. The power sensing element is between the sandwiched what pedestal and the force seat, and when what clinical staff operation drawing muscle, the oppressive force that induction clinical staff force and patient's sole resistance are formed between force seat and pedestal. The speed sensitive element is on setting what pedestal. The present invention forms the oppressive force between the what force seat and the pedestal by the power sensing element measurement, then measures angular speed caused by the pedestal stress Hou by the speed sensitive element, and then provide the quantized data of resistance, draw rate and angle limited degree.一種下肢肌肉痙攣測量裝置，包含一座體單元、一力感測元件，及一速度感測元件。該座體單元具有一頂抵於該患者下肢的底座，及一可相對於該底座運動並提供一臨床人員施力的施力座。該力感測元件是夾設於該底座及該施力座之間，並於該臨床人員操作牽拉肌肉時，感應臨床人員施力與病人腳掌阻力在施力座及底座之間形成的壓迫力。該速度感測元件是設置於該底座上。本發明藉由該力感測元件測量形成於該施力座及該底座之間的壓迫力，再藉由該速度感測元件測量該底座受力後所產生的角速度，進而提供阻力、牽拉速度，及角度受限程度的量化數據。
