Abstract

The scientific literature shows that people with chronic low back pain have altered muscle coordination. This is an interesting marker for evaluating a rehabilitation program because a return to normal could indicate that the injured structures have been repaired. The aim of this study was to implement and evaluate the potential of new electromyographic (EMG) signal analyses in order to quantify the muscle coordination of low back pain subjects. It used an existing database to estimate the metric characteristics and physiological content of these methods in relation to dorsolumbar muscle coordination. While its outcome does not determine the relevance of the processes considered, the good metric qualities of the variables retained and the positive results of the multivariate analyses suggest that these variables are useful for determining the action mechanisms of different conditions of rehabilitation programs for chronic low back pain subjects.
