Balance evaluation device

Abstract

The invention discloses a balance evaluation device. The device comprises a base, force measuring pedals, a pedal linear motion mechanism and a pedal rotary motion mechanism, wherein the pedal linearmotion mechanism is located above the base; the pedal rotary motion mechanism is located above the pedal linear motion mechanism; the force measuring pedals are located above the pedal rotary motion mechanism; the pedal linear motion mechanism is movably connected with the base through a sliding pair; and the pedal rotary motion mechanism is rotationally connected with the pedal linear motion mechanism through a revolute pair. According to the invention, the included angle of the distance between the left force measuring pedal and the right force measuring pedal can be quantitatively adjusted,so that the stress conditions of the human body in different standing postures are measured, and the balance capacity of the human body is evaluated; and under the standing posture, when the human body regularly changes relative to the base, the response generated by the human body to maintain the balance state when the environment changes can be tested. By the device, the balance ability of thehuman body can be comprehensively evaluated under different postures and different environments.

Description

Technical field: [0001] The invention relates to a balance evaluation device, which belongs to the field of rehabilitation and training equipment. Background technique: [0002] The balance ability of the human body means that people perceive the center of gravity of the body when they are active, and then control the center of gravity of the body within the support surface through the movement of various parts such as limbs. It is an indispensable physiological function of the human body. Maintain certain postures while living activities. Studying the stability and control of human balance function is of great significance to sports, disease rehabilitation and elderly care. Studies have shown that patients with stroke, hemiplegia, diabetes, traumatic brain injury, osteoporosis, cervical spondylosis, Parkinson's disease, cervical vertigo, etc. all have partial or complete loss of balance function, and partial or complete loss of balance function And the increased risk of f...

AI Technical Summary

Problems solved by technology

Existing balance assessment devices use a force plate to sense changes in the center of gravity of the body. When users step on the same force plate during use, it is difficult to change the position and orientation of their feet quantitatively. Objective and quantitative evaluation of the balance ability of the human body, and at the same time, in the standing posture, the regular changes of the human body relative to the support surface cannot be realized, so as to test the human body's response to maintain a balanced state when the environment changes
