Physical therapy, 2015

Abstract

Efficient approaches are needed for delivering non-pharmacological interventions for knee osteoarthritis (OA). This trial compared group-based vs. individual physical therapy (PT) interventions for knee OA. 320 patients with knee OA at the VA Medical Center in Durham, NC (mean age = 60 years, 88% male; 58% non-white) were randomized to either the group intervention (GPT; six one-hour sessions, typically eight participants / group) or the individual intervention (IPT; two one-hour sessions). Both programs included instruction in home exercise, joint protection techniques and individual physical therapist evaluation. The primary outcome was the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC; range 0-96, higher scores indicate worse symptoms), measured at baseline, 12 weeks and 24 weeks. The secondary outcome was the Short Performance Physical Battery (SPPB; range 0-12, higher scores indicate better performance), measured at baseline and 12 weeks. Linear mixed m...
