Knee gonarthrosis
Conditions
Interventions
The sensorimotor exercise protocol used in this study was based on randomized controlled trials on the effects of strength, balance and proprioception exercises in patients with knee osteoarthritis. T

| Knee flexor and extensor muscle strength: Subjects performed 3 series of maximal voluntary isometric torque (MVIT) in prone position on a stretcher with the affected joint positioned at approximately 90° to assess knee flexor and extensor muscle strength. For avoiding compensatory movements during the evaluation, the distal segment (ankle) was firmly attached and stabilized by velcro straps connected to an adjustable cuff fixed to the cable [21]. A load cell (Model Miotool, Miotec, Porto Alegre, RS, Brazil) was used to collected force–time traces of most affected member (firmly attached to an adjustable pole that permitted alignment perpendicular to the tested most affected member). To perform the evaluation, subjects were instructed to produce a movement as fast as can and hard as possible, sustaining the contraction for approximately 2–3 s with 1-min rest intervals between efforts. For analysis, one with the highest peak strength (kgF) was used and if value variations were greater than 10% of the mean peak strength, the test was repeated. The peak torque value was calculated by division of value peak strength by body mass value of each subject and multiplied by 100 to normalization. Then, the peak torque percentage was obtained.;Measurement of level of pain: level of pain was assessed using a numeric pain scale. Volunteers were instructed to score their pain in a numeric scale in a range from 0 (absence of pain) to 10 (worst possible pain). ;Measurement of static balance: the static balance was evaluated by Y balance test, which is a reliable and valid tool for quantitative balance assessment. In this evaluation, the subjects are required to reach with one foot in the anterior, posteromedial and posterolateral directions during standing on the affected leg on central markings. Subjects are instructed to reach, being standing in the affected foot, as far as it can and return to the original start position. If the subject failed to maintain unilateral stance, the te | — |

| Evaluation of severity of injury: Knee Injury and Osteoarthritis Outcome Score (KOOS) was used for evaluated the severity of injury. It is constituted by 42 items, with 5 sub-scales, resulting in a score between 0 and 100 (0 representing extreme knee problems and 100 representing no knee problems). The sub-scales assess aspects such as knee pain, function in daily living, function in sport and recreation and quality of life. | — |
