Incorporation of Photobiomodulation Therapy in an Exercise Program With Blood Flow Restriction for Knee Osteoarthritis

29. ledna 2020 aktualizováno: Cid André Fidelis de Paula Gomes, University of Nove de Julho
Knee osteoarthritis (OA) is one of the most common musculoskeletal disorders in the world. The aim of this project is to evaluate the additional effect of photobiomodulation therapy on the quadriceps muscle and knee joint in a blood flow restriction exercise program for individuals with knee OA. To this end, volunteers will be selected at random, aged between 40 and 65 years with pain in one knee, at least in the last 6 months, diagnosed with unilateral knee OA based on the criteria established by the American College of Rheumatology and radiographic confirmation for grades 2 or 3 of the Kellgren-Lawrence Classification, will be randomized into the following groups: (Exercises with blood flow restriction, n = 20), (Exercises with blood flow restriction + photobiomodulation, n = 20) and Exercises with blood flow restriction + placebo photobiomodulation (n = 20). 12 consecutive weeks of treatment will be carried out, with the volunteers being evaluated before and after, using the following instruments: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), sit and stand test, Timed up and Go (TUG), numerical scale pain assessment (END), pain-to-pressure threshold (LDP), skin temperature: quadriceps musculature, knee joint and maximum voluntary isometric contraction (MVIC) of the muscles: quadriceps, middle gluteus. For data analysis, normality test will be used to verify the data distribution and statistical test consistent with the appropriate comparisons within and between groups, thus, two factors are considered in the comparisons, time and group. A significance level of 5% will be adopted.

Aktivní komparátor: Exercises with blood flow restriction
Exercise: 10 minutes of heating on a treadmill without changing the inclination and adopting a standardized speed; Supine bridge, Supine unilateral bridge, Flexion of the hip with the knee extended, Knee extension, volunteer in sedation; Prone knee flexion; Squat on the wall associated with isometric contraction; Abduction of the hip, lateral rotation and knee extension in lateral decubitus associated with isometric contraction; Abduction, lateral rotation of the hip, slight knee and hip flexion performing abduction with the feet together: associated with isometric contraction; Abduction of the hip in orthostatic associated with isometric contraction.Device: The blood flow restriction in mmHg will be performed using a vascular occlusion training manometer, positioned in the thigh inguinal region and inflated to the point where the auscultatory pulse of the tibial artery is interrupted.
Occlusion training is an exercise approach whereby resistance exercise or aerobic exercise is performed whilst an occlusion cuff is applied to proximal aspect of the muscle.
Experimentální: Exercises with blood flow restriction + photobiomodulation
Exercise: 10 minutes of heating on a treadmill without changing the inclination and adopting a standardized speed; Supine bridge, Supine unilateral bridge, Flexion of the hip with the knee extended, Knee extension, volunteer in sedation; Prone knee flexion; Squat on the wall associated with isometric contraction; Abduction of the hip, lateral rotation and knee extension in lateral decubitus associated with isometric contraction; Abduction, lateral rotation of the hip, slight knee and hip flexion performing abduction with the feet together: associated with isometric contraction; Abduction of the hip in orthostatic associated with isometric contraction.Devices: The blood flow restriction in mmHg will be performed using a vascular occlusion training manometer, positioned in the thigh inguinal region and inflated to the point where the auscultatory pulse of the tibial artery is interrupted.Photobiomodulation a mesh composed of multiple diodes containing 50 Infrared LEDs.
Occlusion training is an exercise approach whereby resistance exercise or aerobic exercise is performed whilst an occlusion cuff is applied to proximal aspect of the muscle.
Photobiomodulation therapy is defined as the utilization of non-ionizing electromagnetic energy to trigger photochemical changes within cellular structures that are receptive to photons.
