Conditions

Gonarthrosis

Interventions

Therapeutic exercises: a supervised progressive resistance exercise. The session includes warm-up (10 min)
resistance exercise training with additional load (elastic band and free weights) and weight-bearing exercises (40 min)
and cool-down with static stretching of the muscles (10 min). Low-Level Laser Therapy (LLLT) - complementary intervention: performed immediately after exercise. Laser 808 nm, output power of 100 mW,

Age
40 Years to 75 Years

Inclusion criteria

Inclusion criteria: Present OA diagnosis at least in one knee compartment (tibiofemoral and/or patellofemoral); present grade 2 or 3 in the radiographic examination of OA; present a minimum pain intensity of 4 cm in the visual analogue scale (total of 10 cm) at the most affected knee

Exclusion criteria

Exclusion criteria: Body mass index (BMI) greater than or equal to 35 kg/m2; physical therapy in the 3 months prior to recruitment; intra-articular therapy with steroid anti-inflammatory drugs in the knees 6 months prior to recruitment; ankle, knee or hip surgery of both limbs; and present any medical condition that could affect the participation in the study (cardiorespiratory, neurological and/or musculoskeletal diseases)

Design outcomes

Primary

MeasureTime frame
Pain intensity on the knee, assessed by a 10-cm visual analog scale (VAS), at baseline and post-intervention (right after treatment and at 12 and 24-week follow-up period)—

Secondary

MeasureTime frame
Pain, stiffness and physical function, assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire - global scale ;Physical function, assessed by performance-based tests - 30s Chair Stand Test, 40m Fast-paced Walk Test, and Stair Climb Test;Quality of life, assessed by the SF-36 questionnaire ;Perceived global change after intervention, assessed by a 15-point scale (-7 to +7) of global rating of change—
