Effect of Phototherapy Incorporated Into an Exercise Program on Osteoarthritis of the Knee

December 2, 2015 updated by: Cid André Fidelis de Paula Gomes, University of Nove de Julho
The aim of the proposed study is to analyze the effect of the incorporation of phototherapy into a therapeutic exercise program on pain, functional capacity, range of motion, muscle strength in individuals with osteoarthritis of the knees. The participants will be allocated to different groups through a randomization process using opaque envelopes containing cards stipulating one of the three following groups: Group A (exercise protocol); Group B (exercise protocol + phototherapy protocol); and Group C (exercise protocol + placebo phototherapy protocol). Phototherapy will be performed on the knees diagnosed with osteoarthritis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.
Experimental: exercise group
An exercise program will be performed to increase range of motion, improve motor learning and strengthen the muscles of the lower limb. The program will include exercises 2 times a week for four weeks. The first week the exercises will be performed with 2 sets of 15 repetitions and the remaining weeks 3 sets of 15 repetitions for each exercise. To exercise will be performed with the resistance of cinnamon, It will be recommended weight by 70% of one repetition maximum painless assigned individually per patient.
Other: exercise
Experimental: phototherapy group
And, Phototherapy will be administered with a portable nine-diode cluster. The portable nine-diode cluster will be used overlapping three quadrants of the knee in random sequence: medial quadrant, lateral quadrant and posterior quadrant.with one 905-nm diode (mean power: 1 milliwatt ; peak power: 10 megawatt; spot size: 0.44 cm2), four 875-nm diodes (mean power of each diode: 17.5 milliwatt; spot size: 1 cm2) and four 670-nm diodes (mean power of each diode: 15 mW; spot size: 1 cm2); frequency: 1000 Hz; 300-second irradiation time in each quadrant; total energy: 39.3 Joules per quadrant. Phototherapy will be included in the exercises group.
Other: exercise
Other: Phototherapy
Placebo Comparator: Phototherapy placebo
Phototherapy will be administered with a portable nine-diode cluster. The portable nine-diode cluster will be used overlapping three quadrants of the knee in random sequence: medial quadrant, lateral quadrant and posterior quadrant), with one 905-nm diode (mean power: 0 milliwatt; peak power: 0 watt; spot size: 0.44 cm2), four 875-nm diodes (mean power of each diode: 0 milliwatt; spot size: 1 cm2) and four 670-nm diodes (mean power of each diode: 0 milliwatt; spot size: 1 cm2); frequency: 0 Hz; 300-second irradiation time in each quadrant; total energy: 0 Joules per quadrant. Phototherapy will be included in the exercises group.
Other: exercise

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
physical function
Time Frame: 9 months

9 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame
Maximum voluntary isometric contraction
Time Frame: 9 months
A portable dynamometer will be used to assess muscle contraction.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
