Traveling obstacle avoidance capacity testing device

Abstract

The invention discloses a traveling obstacle avoidance capacity testing device. When a person walks on a pressure detection step pad, a photoelectric virtual obstacle generation device is arranged on the pressure detection step pad; a pressure scanning matrix device in the pressure detection step pad is connected with a control device through a signal acqusition device; the photoelectric virtual obstacle generation device is connected with the control device; a computer is connected with the control device through a communication device; the pressure detection step pad is formed by pressing and fixing a hard base pad, a pressure scanning matrix device and a buffer soft pad; the photoelectric virtual obstacle generation device comprises a plurality of LED (Light Emitting Diode) light strips which are uniformly spaced from one another in parallel; each LED light strip consists of LED lamps which are uniformly spaced from one another along a straight line; the direction of the LED light strips is perpendicular to the walking direction. The device is rational in design; compared with the existing method, the device has the advantages that a state the same as normal walking can be established, a gait parameter is directly measured, the device is safe and reliable, the risk of falling of a tested person is avoided, and the device can be used for testing risks such as falling of old people and the like.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for walking obstacle avoidance ability. Background technique [0002] The degeneration of motor ability is common in the elderly population, and falls are one of the most common consequences of weakened motor ability, which can lead to clinical symptoms such as fractures, trauma and stroke, damage the health of the relevant population, and cause personal and family injuries. Reduced quality of life. Currently, more than half of falls in the elderly population occur when walking over obstacles. [0003] By testing the ability of the elderly and related groups to avoid obstacles while walking, the risk of falls can be assessed, early warning can be given with the help of the assessment results, and suggestions such as the use of walking aids and family companions can be put forward to prevent injuries caused by falls. Therefore, many institutions in the world have researched technol...

AI Technical Summary

Problems solved by technology

However, such technology has the following defects. First, the test is carried out on a running treadmill, and the subjects usually have poor exercise ability and balance ability. There is a hidden danger of subjects, especially the elderly, falling and causing injuries during the test. The second is that the subject is passively walking on the treadmill, and the speed and pace are very different from normal active walking; the third is that the board as an obstacle suddenly falls from the air, which is different from the situation of ground obstacles in daily life Larger, it will also cause psychological impact on the subjects

These deficiencies make the above techniques difficult to be applied in practice
