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.

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.
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.
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.
