Description

A rehabilitation exercise device and guidance system based on body position perception

technical field

The invention belongs to the field of auxiliary rehabilitation training, and in particular relates to a rehabilitation exercise device and a guidance system based on body position perception.

Background technique

Distraction refers to diverting the patient's attention away from the pain itself, and is a common way in pain management. Research on the analgesic effect of distraction is currently focused on experimentally induced pain in healthy subjects or pain induced during acute procedures (eg, needle prick pain). Although these studies have failed to fully demonstrate the analgesic effect of distraction, most studies have shown that distraction does reduce pain in patients to varying degrees. Various hypotheses have been proposed to explain the lack of analgesic effects of distraction in patients with chronic pain. The more common view is that higher levels of pain often produce the emotion of fear. Research has demonstrated that immersive virtual reality (VR) games are a rehabilitation tool for training patients with chronic nonspecific low back pain, distracting patients through motivating properties. Motivation and goal pursuit are considered to be important factors influencing pain attention.

At present, when immersive virtual reality (virtual reality, VR) often uses Pico Neo 2Lite interactive game console (Beijing Xiaoniao Kankan Technology Co., Ltd.) for postural rehabilitation training, there are the following defects:

1. When patients with non-specific low back pain use the Pico Neo 2Lite interactive game console for limb rehabilitation training, the patients will train individually according to medically specific movements, and the rehabilitation training effect will be extremely low because they cannot meet the standards.

2. When patients with non-specific low back pain use Pico Neo 2Lite for limb rehabilitation training, because there is no feedback to the patient based on the patient's limb movement, the training movement is readjusted, resulting in the patient repeatedly performing wrong movements for training, which will not only cause The recovery speed of patients with non-specific low back pain is extremely slow, which may cause limb ligament strain during training.
