Intervention / Treatment
Detailed Description
This is a randomized, triple-blinded (therapist, assessor and patient), placebo-controlled trial, with voluntary patients with non-specific chronic low back pain.
Eighteen patients will be randomly allocated to two treatment groups: Placebo or PBMT and one single session of treatment will be provided.
The data will be collected by a blinded assessor and the outcomes of interest it will be levels of inflammatory markers and pain intensity and it will be collected at baseline and 15 minutes after the single session of treatment.
The statistical analysis will follow the intention-to-treat principles. The findings will be tested for their normality using the Shapiro-Wilk test. Parametric data will be expressed as mean and standard deviation and non-parametric data as median and respective upper and lower limits. Parametric data will be analyzed by two-way repeated measures analysis of variance (ANOVA; time versus experimental group) with post-hoc Bonferroni correction. Non-parametric data will be analyzed using the Friedman test and, secondarily, the Wilcoxon signed-rank test.

Exclusion Criteria:
- evidence of nerve root compromise (i.e. one or more of motor, reflex or sensation deficit);
- serious spinal pathology (such as fracture, tumor, inflammatory and infectious diseases);

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Placebo PBMT
Application of PBMT (Photobiomodulation Therapy) without any dose (0 Joule).
|
The PBMT treatments will be performed using the Multi Radiance Medical™ Super Pulsed Laser MR4™console (Solon, OH, USA), with the LS50 (emitter with an area of 20 cm2) and SE25 (emitter with an area of 4 cm2) cluster probes as emitters.
Nine sites will be irradiated at patient's lumbar region: 3 central sites, using the SE25 (without any dose, 0 J); and 6 sites in the same direction, but laterally (both sides, 3 at a side), using the LS50 (without any dose, 0 J).
Patients will be treated in a single session and they will receive a total dose of 0 J.
|
Active Comparator: Active PBMT
Application of PBMT (Photobiomodulation Therapy) active.
|
The PBMT treatments will be performed using the Multi Radiance Medical™ Super Pulsed Laser MR4™ console (Solon, OH, USA), with the LS50 (emitter with an area of 20 cm2) and SE25 (emitter with an area of 4 cm2) cluster probes as emitters.
Nine sites will be irradiated at patient's lumbar region: 3 central sites, using the SE25 (3000 Hz of frequency, 3 minutes of irradiation per site, 24.75 J per site, a totalizing 74.25 J irradiated from SE25); and 6 sites in the same direction, but laterally (both sides, 3 at a side), using the LS50 (1000 Hz of frequency, 3 minutes of irradiation per site, 24.30
J per site, a total of 145.80 J irradiated from LS50).
Patients will be treated in a single session and will receive a total dose of 220.05
J.

Pain Intensity
Time Frame: 15 minutes after the treatment.
