Abstract

Electromyography (EMG) is an essential tool for assessing muscle performance in human locomotion. The aim of this research is to utilize EMG for assessing the habituation processes of normal adults during treadmill walking compared to floor walking. In this research, EMG activity is presented in linear envelope (LE) form to meet physiological meanings and parameter estimation. The EMG LE is generated from the raw EMG signal through band-pass filtering, rectifying, integration, and normalization procedures. The ensemble averaging of EMG LEs is used to demonstrate the pooled data of six normal subjects. The variance ratio (VR) of the EMG LE is applied to analyze the repeatability of EMG activity and thus to quantify the habituation process of normal adults walking on a treadmill. The habituation results indicated that no pretibial group reached a steady state during 12 minutes of treadmill walking. However the majority of calf groups habituated after 2 minutes of treadmill walking. In addition, changes in EMG phasic activities could be observed for both pretibial and calf groups during treadmill walking.
