The invention discloses a kind of wisdom movement accessories for the muscle group of forging one user of chain. Corresponding one first muscle of muscle group and one second muscle. Wherein, it is mutually interlocked between the first muscle and the second muscle. It includes one first sensing unit, one second sensing unit and a processing unit that wisdom, which moves accessory,. First sensing unit detects one first myoelectricity signal of the first muscle. Second sensing unit detects one second myoelectricity signal of the second muscle. Processing unit receives the first myoelectricity signal and the second myoelectricity signal and the first myoelectricity signal of analysis and the second myoelectricity signal. Whether the ratio difference that processing unit calculates between the first myoelectricity signal and the second myoelectricity signal is situated between one standard deviation range of what or a standard deviation range, and forging the posture of chain to export user is correct or needs modified control signal.本發明揭露一種智慧運動輔具供鍛鍊一使用者的一肌群。肌群對應一第一肌肉與一第二肌肉。其中,第一肌肉與第二肌肉之間相互連動。智慧運動輔具包含一第一感測單元、一第二感測單元與一處理單元。第一感測單元偵測第一肌肉的一第一肌電訊號。第二感測單元偵測第二肌肉的一第二肌電訊號。處理單元接收第一肌電訊號與第二肌電訊號及分析第一肌電訊號與第二肌電訊號。處理單元計算第一肌電訊號與第二肌電訊號之間的比例差是否介於一標準差範圍或一非標準差範圍,以輸出使用者鍛鍊的姿勢是正確的或是需要修正的一控制訊號。
