The effect of low-level laser therapy and physical exercise on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis: a blind randomized clinical trial.

To evaluate the effects of individual and combination therapies (low-level laser therapy and physical exercises) on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis (OA). Subjects with knee OA (Grades 1-3) were evaluated and randomized into four groups: Control Group (CG), untreated; Laser Group (LG), treated with laser at 808 nm, 5.6 J; Exercise Group (EG), treated with exercise; and Laser + Exercise Group (LEG), treated with laser and exercises.

Exercise on balance and function for knee osteoarthritis: A randomized controlled trial.

Objectives: To assess balance and function of symptomatic and asymptomatic subjects with knee osteoarthritis (OA) and investigate the influence of physical exercise.

Design: Subjects were divided into three groups: Group 1 (n = 15), symptomatic knee OA; Group 2 (n = 11), asymptomatic knee OA; and Group 3 (n = 16), knee OA and no intervention. History of falls, the WOMAC questionnaire, balance and functionality were assessed.
