Knee Osteoarthritis
Conditions
Brief summary
Forty six patients with knee osteoarthritis will be randomly allocated into two groups: water-based exercises and land-based exercises. Both of them will receive a strengthening exercise protocol for lower limb muscles. A blind investigator will assess the patients before and immediately after, 3 months and 6 months following the interventions. The main outcomes will be pain, function and strength.
