Gait health assessment method and device

Abstract

An embodiment of the invention provides a gait health assessment method and device. The method comprises following steps: acquiring gait pressure signals, and identifying gait phases by adopting fuzzylogic reasoning rules on the basis of the gait pressure signals; recording a phase sequence of the gait phases; calculating the gait phase duration and the total gait cycle according to phase sequence intervals; counting the abnormal gait cycle deviating from standard gait according to medical standard phase duration on the basis of a Perry model standard gait sequence; and obtaining an abnormalcycle ratio on the basis of the abnormal gait cycle and the total gait cycle, and utilizing the abnormal cycle ratio as gait health assessment basis. According to the embodiment of the invention, a fuzzy logic reasoning system is applied to a gait phase detecting process, stable continuous gait phase detection is realized, trapezoidal and triangular membership functions are adopted in output membership functions, a personal gait phase sequence is not preset, internal difference of individual gaits is taken into consideration, and the method and the device are suitable for meeting gait assessment demands of various crowds.

Description

technical field [0001] The invention relates to the technical field of biological feature recognition, in particular to a gait health assessment method and device. Background technique [0002] Walking is one of the most common daily activities. Whether the gait is healthy or not and how healthy it is can reflect the health status of the human body to a certain extent. Gait analysis is the recording and analysis of human kinematics and dynamics information, aiming to quantify and analyze the factors that control the function of the lower limbs during walking. Accurate gait phase recognition is the basis of personal gait analysis. Determining the gait cycle and the phase in the cycle and its duration can effectively reflect the health of the gait. [0003] The existing gait analysis methods include the following: [0004] (1) Qualitative analysis: mainly used in rehabilitation patients, relying on the qualitative analysis of experienced clinicians, the assessment of patient...
