About

Osteoarthritis is a chronic, multifactorial characterization, which changes in bone alignment, cartilage and structures that provide joint stability appear to be strongly correlated with the origin of this disease.This project will aim to verify the effectiveness of interferential current, short wave and low level laser therapy on an exercise program for mobility and pain in knee osteoarthritis. Blind randomized, placebo controlled. Five groups: exercise group, exercise group + Ultrasound therapy, exercise group + interferential current, exercise group + short-wave diathermy, exercise group + Low level laser therapy. Before and after the trial protocol by the following instruments: Western Ontario and McMaster Universities osteoarthritis index (WOMAC), numerical scale of pain assessment (END), Visual Analogue Scale Fatigue (VAS-F), issue F2.2 Instrument assessment of quality of life of the World Health Organization (WHOQOL-100) test sitting and standing + numerical rating pain scale, algometry. This project hypothesizes that the inclusion of photothermal and electrical agents in an exercise program will provide an improvement in pain, mobility and knee function in individuals diagnosed with knee osteoarthritis.

Enrollment: 100 patients

Sex: All

Ages: 40 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• knee pain to at least six months and minimum of 4 points in pain scale
• Diagnosed with osteoarthritis in unilateral knee according to the criteria established by the American College of Rheumatology and confirmed by radiographic examination for identification Kellgren-Lawrence grade 2 or 3 (Kellgren & Lawrence, 1957).

Exclusion criteria

• Any type of physical therapy
• therapy with intra-articular corticosteroids or therapeutic chondroprotective drugs last year, before the start of the study.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

100 participants in 5 patient groups, including a placebo group

exercise group

Active Comparator group

Description:

An exercise protocol drawn up with the objective will be held to strengthen the musculature: flexor and extensor of the knee; extension, abduction, hip side rotator, using the weight and the elastic band.

Treatment:

Other: exercise

exercise group + Ultrasound therapy

Placebo Comparator group

Description:

Apart from intervening in the exercise group, an ultrasound device is used .

Treatment:

Other: exercise

Device: Ultrasound therapy

exercise group + interferential current

Experimental group

Description:

Besides the intervention of the exercise group after the exercises will be applied to interferential current through the device. Will be positioned 4 electrodes (8x5 cm), two upper and two lower (forming a square) around the center of the knee.

Treatment:

Device: interferential current

Other: exercise

exercise group + short-wave diathermy

Experimental group

Description:

Besides the intervention of the exercise group after the exercises will be applied diathermies short wave in continuous mode. For that will be used apparatus, 27.12 megahertz, by means of vulcanized rubber electrodes (12x17 cm) with gentle warming for 30 minutes.

Treatment:

Other: exercise

Device: short-wave diathermy

exercise group + Low level laser therapy

Experimental group

Description:

Apart from intervening in the exercise group, will be applied to Low level laser therapy, through the laser unit, Class 3b, gallium-aluminum-arsenide, continuous mode, wavelength: 830 nanometer, power: 30 watts.

Treatment:

Other: exercise

Device: Low level laser therapy
