An upper limb rehabilitation training system for stroke patients

Abstract

The invention discloses an upper limb rehabilitation training system for stroke patients. The patient wears an immersive virtual reality head-mounted device and experiences the training scene from a first-person perspective in a virtual environment. At the same time, there is a virtual spherical rehabilitation device in the scene. The patient passes through the hemiplegic side The hand controls the arm movements in the virtual scene in real time to interact with the spherical instrument. The patient pushes the ball forward and the healthy side on the virtual training plane to drive the affected side forward. This repetitive training activity can not only promote the forward shift of the center of gravity, enhance the patient's upper limb control ability, but also inhibit the affected side spasm; Pushing the ball to the affected side is used to promote the automatic weight-bearing of the affected limb, improve muscle strength and control ability; hold the ball to perform forearm supination, inhibit pronator muscle spasm and improve forearm control ability.

Description

Technical field [0001] The present invention belongs to the field of medical rehabilitation of brain injury, specifically relates to a stroke patient upper limb rehabilitation training system. Background [0002] Stroke patients with hemiplegia upper limb rehabilitation training is one of the key and difficult research directions in the field of rehabilitation medicine, conventional upper limb rehabilitation training is complete, but the training process is monotonous, the content is boring, the patient's interest in long-term repeated training is reduced, and the self-confidence of recovery is reduced. On the other hand, the occupational therapist's labor intensity is high, and it is often necessary to assist patients in training and verbal counseling, which is prone to fatigue and leads to inefficient training with patients. [0003] Virtual Reality (VR) technology has the characteristics of immersion, interactivity and imagination, and has been widely used in rehabilitation re...

AI Technical Summary

Problems solved by technology

Existing projects that combine VR technology with rehabilitation training lack force-tactile interaction with users. Patients have positive emotions and a high willingness to participate in training in the virtual world, but pure virtual exercises lack real-feeling feedback. Although they can mobilize patients’ emotional stimulation, However, it cannot meet the requirements of traditional rehabilitation training to promote the main points of neural remodeling
