A new design of therapeutic traction modality with closed loop traction force control based on EMG signals from selected muscle is developed for rehabilitation. This modality includes main traction controller, a high signal-to-noise ratio EMG scanning and processing units, A/D and D/A computer interface hardware, on-line self-adjusted traction force actuating unit, biofeedback control software, and audio/visual alarms. This new traction modality provide a breakthrough milestone for the open loop control architecture of conventional motorized traction machine. The kernel of this invented modality is to adaptively adjusting traction force based on real time detected EMG signals to ensure the safety, comfort, and effectiveness of traction therapy.
