Osteoarthritis, Knee, Quadriceps Muscle Atrophy
Conditions
Brief summary
Introduction: Osteoarthritis (OA) of the knee is a musculoskeletal disorder and is associated with significant implications related to public health and socioeconomic factors resulting in leave from work. Currently, there are several types of conservative treatment for this pathology, such as medications and mainly muscle strengthening, recommended by international guidelines. It can be associated with neuromuscular electrostimulation (NMES) as with the Aussie Current, for example, which aims to increase strength and function earlier. Objective: To determine whether the effectiveness of adding NMES to the Aussie Current in patients with knee OA who receive treatment based on the principles of conventional physiotherapy, in relation to pain relief, improvement of functional disability and muscle strength. Materials and Method: Forty individuals will be randomly distributed in two groups, with group 1 (G1) exercises and placebo application of electrostimulation and group 2 (G2) exercises and application of NMES with the Aussie current in the quadriceps femoris muscle. In the treatment, 24 sessions will be carried out in a period of 12 weeks based on the gold standard for the treatment of knee OA. Clinical outcomes of pain intensity, functional disability and muscle strength will be measured at baseline, immediately after 12-week treatment and after 24-week follow-up by a single blinded evaluator at all stages. All statistical procedures will be carried out following the principles of intention to treat and the comparison between groups will be carried out through the test of Mixed Linear Models. Expected Results: It is expected that there will be improvement in the variables: pain, functional capacity and strength in both the groups, however in the group that carried out the application of the Aussie Current, the gains would be more precocious, when compared to the group that did not carry out the NMES.
