A three-dimensional gait analyzer

Abstract

The invention discloses a three-dimensional gait analysis meter which comprises a first posture sensor, a second posture sensor, a third posture sensor, a fourth posture sensor, a fifth posture sensor, a sixth posture sensor, a seventh posture sensor and a controller. Compared with the prior art, the three-dimensional gait analysis meter can provide a more intelligent and more integrated analysis scheme, personal errors do not exist, time is shortened, accuracy is high, and a richer training mode is provided.

Description

technical field [0001] The invention relates to the field of gait analysis, in particular to a three-dimensional gait analyzer. Background technique [0002] Human movement is the result of the rhythmic contraction of more than 1,000 muscles controlled by the nervous system and the coordinated movement of more than 200 bones around more than 100 joints. Although life science research has made great progress in recent years, it is still far from simulating the process of brain controlling limb movement. Therefore, researchers in rehabilitation medicine and sports generally use macroscopic movement of human limbs to diagnose human motor function diseases and evaluate human body. Rehabilitation process, guiding physical training and material selection. [0003] The existing methods of measuring and analyzing gait are as follows: [0004] 1. Footprint method: use naked eye observation to make some simple time and space records. Sprinkle lime powder on the ground, let the subj...

Problems solved by technology

There are many obvious defects in this method, such as: long preparation time; it requires a lot of manpower; the analysis is mainly subjective and the accuracy is low; the data obtained is less; clinical reports are filled in manually, which is time-consuming, laborious and error-prone

[0005] 2. Video method: The process of human walking is captured by video equipment (CCD camera), and then the lattice analysis is performed frame by frame. The advantage is that the equipment is simple and the gait of the subjects is relatively natural. Relying on manual work requires relatively high operating requirements and relatively large errors, and only two-dimensional plane analysis can be performed, and the accuracy of three-dimensional spatial analysis cannot be guaranteed

Its advantage is that the equipment price is relatively low, the operation is relatively simple, and the data is relatively accurate; however, ultrasonic waves are easy to reflect, and the interference of surrounding objects must be eliminated, and the requirements for the surrounding environment are high. The number of marker points is limited, and it is only suitable for segmental analysis of human body
