The present invention provides a measuring instrument for fall risk assessment comprising a muscle strength measuring platform, a sensor and a muscle force data calculating device. The muscle strength measurement platform is used to carry the test subjects to perform the fall risk assessment. The sensor is set on the muscle strength measurement platform to measure the strength of the measured muscle strength. The force data computing device is an electrical connection sensor and has a processing unit, a storage unit and an operation unit. The processing unit receives one of the operating units to control the sensor and then evaluates the risk of the person to be tested by the strength of the muscle strength and stores the strength of the muscle strength to the storage unit.本發明係提供一種跌倒風險評估系統,包含了肌力量測平台、感測器以及肌力數據運算裝置。肌力量測平台用以承載待測者,以執行跌倒風險評估量測。感測器係設置於肌力量測平台上,以量測待測者之肌力穩健度數值。肌力數據運算裝置係電性連接感測器,並具有處理單元、儲存單元和操作單元,處理單元係接受操作單元之一指令控制感測器,再透由肌力穩健度數值,評估待測者之跌倒風險,並儲存肌力穩健度數值至儲存單元。1‧‧‧跌倒風險評估系統1a‧‧‧待測者10‧‧‧肌力量測平台20‧‧‧感測器30‧‧‧肌力數據運算裝置303a‧‧‧螢幕303b‧‧‧鍵盤
