Abstract

The invention discloses a gait abnormal degree evaluation method for wearable equipment and the equipment thereof, and the method comprises the steps: calculating and outputting a gait parameter and an abnormal degree comprehensive index of a user by employing angular speed and acceleration data collected by two inertial sensor units. According to the gait abnormal degree evaluation method, gait parameter information of each step when a user walks can be measured and output, the gait parameter information is compared with a gait parameter database of a healthy person, and the abnormal degree comprehensive index of the gait of the user is calculated. The method is convenient to use, is not limited by places, is low in cost, can achieve the high-precision evaluation of the gait of the user,is higher in reliability, and is better in popularization prospect.

Description

technical field [0001] The invention relates to a method for evaluating the degree of abnormal gait used in a wearable device and the device. Background technique [0002] Gait parameters are physical parameters in the process of human walking, which can reflect human movement ability and have great application value. Therefore, many researchers are currently studying the measurement of gait parameters. The equipment for measuring gait parameters in large laboratories, such as optical motion capture systems, force plates, etc., are often used in clinical gait parameter detection and comprehensive abnormality assessment, but they are expensive, limited by space, and inconvenient to use, etc. shortcoming. Wearable sensors include inertial measurement units, ultrasonic sensors, miniature cameras, etc. Compared with large-scale laboratory equipment for measuring gait parameters such as optical motion capture systems, force plates, etc., they are small, cheap, and unaffected. T...
