Key parameters and sensitivity analysis of lower limb muscle strength in young men with different gait patterns.

ABSTRACT:

Objective

To explore the functional characteristics and principal component differences of electromyography in different phases of the gait cycle, to provide key parameters for identifying a complete gait, and to provide a reference for joint moment solving in the lower limb.

Methods

Twenty young men were selected to measure the natural gait EMG of 14 muscles of the lower limb using VICON and NORAXON devices. Gait was classified into two categories according to the Niyogi S A classification, integral EMG differences were compared, and principal component analysis was performed on the differing muscles to calculate Cohen's d values for significant differences and ΔIEMG values for non-significant differences.

Results

(1) Significant differences existed in the integral E
