Osteoarthritis, Physical Therapy Modalities
Conditions
Brief summary
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.
Interventions
OTHERexercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
DEVICEinterferential current
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
DEVICEshort-wave diathermy
Is a modality that produces deep heating via conversion of electromagnetic energy to thermal energy
DEVICELow level laser therapy
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.
DEVICEUltrasound therapy
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.

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. * history of trauma on his knees, cognitive disorder or psychological disorder, * neurological (sensory or motor) * cancer * diabetes, * or any state of adverse acute health osteoarthritis signs of hip * cardiopulmonary disease that prevents the conducting exercises * require auxiliary device for performing gait. * Yet who undertake physical activity in the last two months. Physical activity is defined as strength training and / or more than 20 minutes of aerobic activity twice a week.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| pain | Change from Baseline in The Western Ontario and McMaster Universities Arthritis Index at 8 weeks | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation Knee Osteoarthritis. |
| stiffness | Change from Baseline in The Western Ontario and McMaster Universities Arthritis Index at 8 weeks | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation Knee Osteoarthritis. |
| physical functional | Change from Baseline in The Western Ontario and McMaster Universities Arthritis Index at 8 weeks | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation Knee Osteoarthritis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| intensity of pain | Change from Baseline in The Numerical rating pain scale at 8 weeks | The Numerical rating pain scale, a simple, easily administered scale evaluates the perceived intensity of pain, using an 11-point scale from 0, representing 'no pain', to 10, which is the 'worst possible pain'. |
| level of pressure pain | Change from Baseline in ThePressure Pain Threshold at 8 weeks | Pressure Pain Threshold in the knee with algometer dynamometer. |
| Self-perceived fatigue | Change from Baseline in the self-perceived fatigue at 8 weeks | a visual analog scale (VAS-F). |
| Functional capacity for sitting and standing | Change from Baseline in The Functional capacity for sitting and standing at 8 weeks | sitting-rising test |
