Details and patient eligibility

About

This study is to quantify changes in muscle activity and pelvic stability during prolonged walking in patients with symptomatic lumbar spinal stenosis (sLSS) and healthy control subjects and to determine their association with the severity of the stenosis and the crosssectional area and fatty atrophy of lumbo-pelvic-hip muscles.

Enrollment: 39 patients

Sex: All

Ages: 30 to 80 years old

Volunteers: Accepts Healthy Volunteers
