Accurate positioning method of rehabilitation FES signal for stroke patients

Abstract

The invention relates to the fields of biomedical engineering, computer technology and communication, and specifically discloses an accurate positioning method of a rehabilitation FES signal for stroke patients. The method comprises the steps of wearing a dynamic exoskeleton, defining sensor parameters, performing healthy joint movement, recording exercise data of a healthy joint and the myoelectric signal data of adjacent limbs, and calculating the corresponding motion data of an affected joint and the action time and action point of the FES. The accurate positioning method determines a functional electrical stimulation site and a timing of the affected joint through the healthy joint motion of the patients, instead of determining by the experience of a rehabilitation engineer, by using the principle of time-lapse mirroring, each patient can find electrical stimulation time and action positions suitable for own physical conditions, the FES stimulation on the patients makes the actionof the patient affected joint closer to the action of normal limbs, which can better improve the activation of the brain mirror neurons and promote the rehabilitation of the patients, and the method can help the stroke patients to correct gait during the rehabilitation process to a certain extent.

AI Technical Summary

Benefits of technology

This technology helps people who have suffered from strokes recover more effectively when they receive an electric shock that activates specific parts within them called nerve cells involved with muscle control functions. By accurately placing electrodes on these areas, this treatment improves blood flow around those regions where there was no damage caused due to lack of oxygen or other factors like drugs used later after surgery. It also allows cerebral cortex activity to be restored faster than if done without any interference from external sources such as lightning strikes.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the accuracy and speed of locating neuronal targets during physical rehraining sessions that require electrostimulations to help recovery from neurological disorders such as strokes caused by injury. Current methods involve manually adjustment of electric current intensity over time based solely upon visual observation alone without any objective measurement tools like sensors attached directly onto the body being treated. This process takes too long and causes unnecessary repetitive stress injuries to both individuals involved and caregivers who must work together to achieve effective results.
