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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| exercise group | Active Comparator | 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. |
|
| exercise group + Ultrasound therapy | Placebo Comparator | Apart from intervening in the exercise group, an ultrasound device is used . |
|
| exercise group + interferential current | Experimental | 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. |
|
| exercise group + short-wave diathermy | Experimental | 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. |

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. |
|
| interferential current | Device | The basic principle of Interferential Therapy (IFT) is to utilise the significant physiological effects of low frequency (<250pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low frequency stimulation |
|
| short-wave diathermy | Device | Is a modality that produces deep heating via conversion of electromagnetic energy to thermal energy |
|
| Low level laser therapy | Device | Laser treatment in which the energy output is low enough so that the temperature of the treated tissue does not rise above 98.6°F (36.5° C) or normal body temperature. |
|
| Ultrasound therapy | Device | Ultrasound (US) is a form of mechanical energy, not electrical energy and therefore strictly speaking, not really electrotherapy at all but does fall into the Electro Physical Agents grouping. |
