AI Technical Summary

Technical Problem

Existing CPM rehabilitation devices and electrical stimulation therapies cannot achieve personalized parameter settings when treating disuse muscle atrophy, resulting in limited improvement in muscle activity. Furthermore, continuous electrical stimulation may induce muscle fatigue. Traditional sEMG signal feedback methods cannot be adjusted according to the active movement of human joints.

Method used

The system employs a functional electrical stimulation device based on sEMG feedback combined with a CPM rehabilitation device. Through an electromyography acquisition module and a host computer processing module, data filtering and algorithm processing are performed to adjust the intensity and location of electrical stimulation in real time. Combined with joint angle feedback, it achieves intelligent rehabilitation treatment.

Benefits of technology

It enables personalized electrical stimulation parameter settings, combined with active and passive movements, which improves muscle activity, reduces muscle fatigue, and enhances the effectiveness and accuracy of rehabilitation treatment and assessment.

Abstract

The application discloses a rehabilitation treatment evaluation system of a functional electric stimulation device combined with a CPM rehabilitation device. An electrode module is attached to the surface of a measurement site, an electromyography acquisition module acquires original sEMG signals from the electrode module and sends the signals to an upper computer processing module, the upper computer processing module acquires the sEMG signals from the electromyography acquisition module and filters the signals, data processing is performed to obtain electric stimulation intensity and feedback electric stimulation parameters which are sent to a functional electric stimulation module, a CPM rehabilitation module receives external real-time angle parameters, the functional electric stimulation module receives the electric stimulation intensity real-time feedback to control electric stimulation, receives the feedback electric stimulation parameters and the real-time angle parameters to update a feedback control site. The application intelligently adjusts the parameters and sites of the electric stimulation on the surface of the human body, achieves the effect of adapting to the real-time state of the human body, and combines active movement and passive movement by adding the lower limb joint rehabilitation period CPM, so that the muscle activity of a patient is provided and the problem that muscle fatigue is caused by continuous electric stimulation is reduced.
