Summary

Lumbar pain, or low back pain, may be defined as pain or discomfort located from the lower portion of the costal margin to the gluteal folds, with or without referred pain in the legs. This pain is classified as non-specific lumbar pain when its cause is unknown, as well as chronic when it persists for longer than three months with the appearance of disabilities for activities of daily life. Treatments for low back pain are usually pharmacological, focusing on analgesics, muscle relaxants and anti-inflammatories. Although protective factors, such as exercise, healthy diet and functional training may mitigate the evolution of pain, physical disability due to pain and functional loss reduce quality of life. Photobiomodulation (PBM) can be defined as the therapeutic use of light sources to reduce inflammation and relief pain. In this context, the objectives of this study are to develop and evaluate the effectiveness of an application protocol of an LED cluster for the treatment of chronic low back pain in a randomized, double-blind clinical trial that will be conducted in the outpatient facility of Universidade Nove de Julho (Uninove). Patients with chronic nonspecific low back pain, who signs the Informed Consent Form approved by the Uninove Institutional Review Board will be included in the study. Treatment sessions will be performed with a LED cluster three times a week for 4 weeks (totaling 12 sessions) in the lumbar region, and the outcomes will be measured with the following evaluations: VAS - Visual Analog Scale; Roland-Morris Disability Questionnaire (RMDQ); Schöber test; Modified Oswestry Disability Questionnaire and Algometry.

Conditions

  • Low Back Pain

Interventions

RADIATION

LED Photobiomodulation

A total of twelve laser applications (3 sessions per week) will be provided to the patients as treatment. A LED board with wavelengths of 660nm and 850nm at 5mW of power will be used for 30 minutes, resulting in a total energy of 3J per point in each session. The application site will be the lumbar region, in contact with the skin. The LED cluster (light-emitting diodes) has 72 LEDs.

OTHER

Placebo LED Photobiomodulation

For the placebo group, the procedures will be the same, however the LED equipment will remain off.
