The groups were divided between 1 and 2, which was group 1 with patients who presented osteoarthritis in the knees, without specific complaints of hand, but with radiographic findings and group 2 was characterized by patients with radiographic signs and symptoms of hands that presented larger functional limitations in the daily routine or that were eligible for rehabilitation treatment using orthosis models such as resting hand volar splints, thumb stabilization splints or finger volar splints with nocturnal support, aiming at the relief of the pain, stabilization of the affected joints and the prevention of the appearance/aggravation of deformities. Exercise guidelines for maintenance of muscle strength for thumb and fingers were performed in patients who presented significant improvement of pain.
