J023014 Analysis of biarticular muscle motion for identifying the pathogenesis of intermittent claudication

Abstract

Intermittent claudication is a gait disorder due to peripheral arterial disease (PAD) and lumber spinal canal stenosis (LSS). The purpose of this study is to identify the pathogenesis of intermittent claudication with a simple and minimally invasive measurement system, for the purpose disease-specific factors are extracted. However, the obtained results are limited since only uni-angle was considered. This paper estimates the length of the biarticular muscle to derive new factors for differentiation. We will create a two-dimensional muscle model from anatomical model and drawings, length data of biarticular muscle was calculated by substituting the time series of measurement data to this. We were able to find a significant difference in maximally expanded and maximally relaxed muscle length and motion range which was calculated from the measured data.
