Abstract

The invention discloses a three-dimensional gait analysis system and method based on an inertial sensor. The three-dimensional gait analysis system comprises wearable equipment, a data acquisition client, a server platform and a gait display client, according to the invention, on the basis of the inertial sensor with low price, the three-dimensional gait motion can be effectively reproduced only by using the acceleration and angular velocity data of the key part in the gait motion process, and related gait parameters are calculated.

Description

technical field [0001] The invention belongs to the technical field of inertial perception and gait rehabilitation monitoring, and in particular relates to a three-dimensional gait analysis system and method based on inertial sensors. Background technique [0002] In today's medical system, the monitoring mode of gait rehabilitation training still adopts the method of real-time supervision and guidance of medical staff - medical staff first analyze the patient's gait, that is, according to the patient's walking posture, walking speed, joint and muscle Activities, balance coordination control and other factors are checked and analyzed to determine the characteristics and causes of the current gait, so as to help patients choose assistive devices and formulate corresponding training programs in a timely and effective manner. In this process, medical staff generally record the patient's training data by experience, and direct guidance through visual observation. [0003] Altho...
