About

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.

Enrollment: 20 patients

Sex: All

Ages: 40 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Diagnosis of osteoarthritis of the knee (unilateral) according to criteria of the American College of Rheumatology
• age between 40 and 80 years
• either gender
• knee pain and functional disability for at least six months confirmed by historical medical.

Exclusion criteria

• Dementia
• neurological disorder (sensory or motor)
• cancer
• diabetes
• acute adverse health condition
• symptoms of osteoarthritis of the hip
• cardiopulmonary disease that impedes walking
• need for wheelchair or gait-assistance device
• and having received steroids through intra-articular injection or orally in the previous six months

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

20 participants in 3 patient groups, including a placebo group

exercise group

Experimental group

Description:

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.

Treatment:

Other: exercise

phototherapy group

Experimental group

Description:

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: Phototherapy

Other: exercise

Phototherapy placebo

Placebo Comparator group

Description:

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.
