Muscular and Functional Capacity in Subjects Under Treatment for Knee Osteoarthritis: Role of Physical Activity Status.

: The purpose of this study was to assess the role of physical activity (PA) in muscular and functional capacity in subjects under treatment for knee osteoarthritis submitted to an interdisciplinary educational program emphasizing the regular practice of PA and exercises. : Subjects under treatment for primary knee osteoarthritis (N = 136; age = 66 [3]) were allocated in sedentary to sedentary (SED-SED, sedentary or insufficiently active at pre and post), active to sedentary (ACT-SED, active or very active at pre and sedentary or insufficiently active at post), sedentary to active (SED-ACT, sedentary or insufficiently active at pre and active or very active at post), and active to active (ACT-ACT, active or very active at pre and post) groups. Muscular capacity (isokinetic test), functional capacity (timed up and down stairs test, timed up and go test, and 5 times sit to stand test), and daily living PA (International PA Questionnaire short version) were assessed before and after (12 mo) the follow-up.

Educational program promoting regular physical exercise improves functional capacity and daily living physical activity in subjects with knee osteoarthritis.

Background: Physical exercise and educational programs promote several benefits for patients with knee osteoarthritis (OA). However, little is known about the effects of educational programs promoting the regular practice of physical exercise. The purpose of the present study was to assess the effect of an interdisciplinary educational program, emphasizing the recommendation for regular practice of physical exercise, on functional capacity and daily living physical activity in individuals with knee OA.

Effects of Motor Learning on Clinical Isokinetic Test Performance in Knee Osteoarthritis Patients.

Objectives:: To analyze the effects of motor learning on knee extension-flexion isokinetic performance in knee osteoarthritis patients.

Methods:: One hundred and thirty-six middle-aged and older sedentary individuals (111 women, 64.3±9.
