Surface Electromyogram for Gait Analysis of Low Back Pain subjects

This paper describes surface electromyogram (sEMG) recordings of the lumbar muscles during walking. The intent of these pilot trials was to evaluate the usefulness of the sEMG in differentiating between two groups of subjects: healthy subjects and those with lower back pain. An analysis of the features of the sEMG was performed for clearly defined walking activities for both subject groups. The results showed no significant variance of amplitude between the subject groups. It is proposed to extend the same methodology to running in order to expose any underlying difference.
