Multi-sensory stimulation hand function rehabilitation system and method based on virtual reality game

Abstract

The invention discloses a multi-sensory stimulation hand function rehabilitation system based on a virtual reality game, relates to the field of rehabilitation engineering and virtual reality, and can provide active and passive collaborative rehabilitation training and increase the participation degree and reality sense of a patient so as to achieve a whole-link rehabilitation effect. The rehabilitation system comprises a data glove, a hand rehabilitation exoskeleton, a hand posture visual monitoring device, a sensory feedback system and a control unit; the hand posture visual monitoring device is used for collecting the position and posture data of the hand on the affected side, mapping the hand on the affected side into the virtual reality game, controlling the virtual hand to move according to the posture data, and collecting the position information of the virtual hand; the sensory feedback system is used for generating at least one sensory feedback; the control unit is configured to receive the position information of the virtual hand and judge whether the position information meets a preset condition or not, and if yes, the sensory feedback system is controlled to act. The invention further provides a rehabilitation method based on the rehabilitation system.

Description

technical field [0001] This application relates to the fields of rehabilitation engineering and virtual reality, and specifically relates to a multi-sensory stimulation hand function rehabilitation system and method based on virtual reality games. Background technique [0002] Stroke is a group of diseases caused by the sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to blood vessel blockage, resulting in brain tissue damage. Severe cases can lead to death, and those who recover will also leave sequelae of varying degrees, such as hand movement on the affected side. limit, which seriously affects the quality of life. The hand is a part that is frequently used in life, has many functions, and has a flexible structure. Its rehabilitation is of great significance for patients to be able to carry out normal life independently. [0003] After a stroke, the nerve center of the patient is damaged, and the motor and sensory function...

AI Technical Summary

Problems solved by technology

Although the existing rehabilitation robots can provide a good standardized rehabilitation program, most of them are passive rehabilitation models, so they cannot promote the patient's active rehabilitation intention well, so they cannot complete the motor neuron reconstruction well

In addition, due to the lack of feedback means in the existing rehabilitation robots, the recovery of the patient's perception cannot be well stimulated.
