Description
Summary:Abstract Objective To examine the effects of high-intensity laser therapy (HILT) on pain sensitivity and motor performance in patients with thumb carpometacarpal (CMC) osteoarthritis (OA). Design Prospective, triple-blinded, randomized, placebo-controlled trial. Setting Private practice, Malaga, Spain. Subjects Forty-three patients (mean ± SD age = 71 ± 12 years) with a diagnosis of thumb CMC OA grade 1–2 were randomized to the control group (N = 21) or experimental group (N = 22). Methods The experimental group (ExpG) received high-intensity laser therapy (HILT), and the control group (ConG) received a placebo treatment. The outcome measures were pain intensity (visual analog scale) and key pinch strength measurements (dynamometer). All outcome measures were collected at baseline, immediately following the intervention, at four weeks, and at 12 weeks following the intervention. Results Analysis of variance revealed a group × time interaction (F = 40.8, P
