Abstract

The present invention provides an intelligent interactive-rhythmic neuromuscular rehabilitation system, comprising: a surface electromyography sensor configured to collect a user'"'"'s electromyographic signal; a signal transmitter configured to receive and transmit the electromyographic signal; a rhythmic interaction module configured to generate and provide a specific rhythm to the user and receive the electromyographic signal, such that when the electromyographic signal matches the specific rhythm, a positive feedback is provided; otherwise, a negative feedback is provided. The intelligent interactive-rhythmic neuromuscular rehabilitation system enables a user to constantly strengthen a target muscle or muscle group by a rhythmic interaction module, and to be familiar with the voluntary control of target muscle by motor nerve control and suppressing improper muscle contraction, thereby achieving muscle balance; The system is characterized by its high interactivity, intelligence, and entertainment. It enhances the user'"'"'s adherence to the long-term treatment, and makes user'"'"'s self-treatment possible.
