Abstract

IMPORTANCE: There is limited evidence supporting use of physical therapy for hip osteoarthritis. OBJECTIVE: To determine efficacy of physical therapy on pain and physical function in patients with hip osteoarthritis. DESIGN, SETTING, AND PARTICIPANTS: Randomized, placebo-controlled, participant- and assessor-blinded trial involving 102 community volunteers with hip pain levels of 40 or higher on a visual analog scale of 100 mm (range, 0-100 mm; 100 indicates worst pain possible) and hip osteoarthritis confirmed by radiograph. Forty-nine patients in the active group and 53 in the sham group underwent 12 weeks of intervention and 24 weeks of follow-up (May 2010-February 2013) INTERVENTIONS: Pa..
