简要总结
Knee Osteoarthritis is a degenerative disease associated with muscle weakness, arthralgia, rigidity and postural instability. Therapeutic exercise can reduce pain and improve muscle strength and postural balance, however benefits from association with pompage is not known. This study aims to evaluate the effects of therapeutic exercise on pain, muscle strength and postural balance in elderly women with knee osteoarthritis. Methodology: Almost randomized controlled trial, in which were included elderly between 60 and 80 years diagnosed with knee osteoarthritis, randomized into two groups with 11 participants each. Intervention group held strengthening exercises for flexors and knee extensors, balance training, and manual knee pompage for 12 weeks. Control Group received educational lectures. Arthralgia was estimated by pain subscale of the questionnaire Western Ontario McMaster Universities Osteoarthritis Index and (WOMAC); muscle strength was assessed by the isokinetic dynamometer HUMAC® NORM Testing & Rehabilitation System and the postural balance by the Biodex Balance SD postural stability protocol (Biodex Medical Systems, Inc. New York, USA). The Student t test was used for statistical analysis.

结局指标
主要结局
The concentric muscular peak torque of the knee extensors
时间窗: 3 months
By isokinetic dynamometer HUMAC® NORM Testing \& Rehabilitation System. It was rated the peak concentric muscle torque of knee extensors of both lower limbs at the speed of 120º/s. Patients were instructed to perform the knee extension at maximum amplitude pain-free permitted, then the maximum pain-free range in flexion. Movements of extension and flexion were performed five times for the participants to familiarize themselves with the procedure before the test. Then, five replicates were performed, and the highest amount recorded as peak muscle torque. All data were corrected by gravity. The values recorded in Newton-meters (Nm) were adjusted for body weight (kg) and presented as a percentage. For better analysis of peak concentric muscle torque of the knee extensors, the more symptomatic knee was assessed using the Visual Analogue Scale (VAS).
Postural stability
时间窗: 3 months
We used the Postural Stability Protocol, bipedal evaluation, eyes open eight resistance level and three repetitions of 20s with 10s rest. To mark the position of the feet, was adopted as the reference line of the heel and toe of the average tendon. The patient is positioned in front of a monitor containing a target and a cursor and Postural Stability protocol information. The therapist effected verbal command for the patient to keep a point at the center of the target, in which a lowest score (least deviation from the center) was desirable. The hand support or withdrawal of the platform legs was not allowed. Before the test, a simulation of the procedure was performed.
