Influence of Using Physical Therapy Resources for Knee Osteoarthritis (osteoarthritis)

February 15, 2018 updated by: Cid André Fidelis de Paula Gomes, University of Nove de Julho
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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: exercise group
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.
Other: exercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
Placebo Comparator: exercise group + Ultrasound therapy
Apart from intervening in the exercise group, an ultrasound device is used .
Other: exercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
Device: Ultrasound 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.
Experimental: exercise group + interferential current
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.
Other: exercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
Device: interferential 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
Experimental: exercise group + short-wave diathermy
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.
Other: exercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
Device: short-wave diathermy
Is a modality that produces deep heating via conversion of electromagnetic energy to thermal energy
Experimental: exercise group + Low level laser therapy
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.
Other: exercise
exercises designed with the objective of strengthening the musculature: flexor and extensor of the knee; extensor, abductor, lateral rotator of the hip.
Device: Low 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.
