  • Knee Osteoarthritis


The investigators assessed overall physical activity and sleep quality in subjects with knee osteoarthritis(OA) at baseline, and at four and 12 weeks following initiation of physical therapy. Subjects received a course of manual physical therapy with interventions targeted to relevant impairments in the lower quarter.
