Detailed Description
To achieve the proposed objectives it will be performed a randomized, triple-blind, placebo-controlled trial, with voluntary patients with fibromyalgia. Ninety patients will be randomly allocated to two treatment groups: 1. Active PBMT (MR5™ ACTIV PRO LaserShower) or Placebo PBMT (MR5™ ACTIV PRO LaserShower). The patients will be treated by a blinded therapist.
The patients randomly allocated to the different groups will be subjected to treatment 3 times a week, total of 9 sessions (with approximately 48 hours between each session), a total of 3 weeks of treatment.
The clinical outcomes will be obtained at the stabilization phase, baseline, end of treatment and 30 days after the conclusion of treatment.
The data will be collected by a blinded assessor.
Statistical analyzis:
- The primary statistical method to analyze the primary endpoint will be Fisher's Exact Test to compare the proportion of success between the test (Active PBMT) and the control procedure (Placebo PBMT) groups, considering that randomization has been diligently conducted and important covariates between the two groups are well balanced. Statistical significance is set at p < 0.05.
- Unpaired T test will be applied to analyze pain intensity through EVA. Mean and individual subject changes in VAS ratings across and between all study evaluation time-points, within and between procedure groups considering that randomization has been diligently conducted and important covariates between the two groups are well balanced. Statistical significance is set at p<0.05.
- For patient satisfaction, measured through a Likert Scale, the data will be reduced to the nominal level by combining all agree and disagree responses into two categories of "accept" and "reject". Differences in satisfaction with Study Outcome Ratings between procedure groups at both evaluated time-points, and any change between. The chi-square, will be used after this transformation. Statistical significance is set at p<0.05.
The investigators will analyze: degree of pain rating (tender point count), pain intensity, patient satisfaction and adverse events

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Active PBMT
Active PBMT applied three times a week (interval of 48 hours approximately), for three consecutive weeks, totalling nine treatment sessions.
|
The Active PBMT will be applied using MR5™ ACTIV PRO LaserShower Laser Therapy System, manufactured by Multi Radiance Medical (Solon, OH, USA) will be used.
The ACTIV PRO emits 30mW of 905nm, 300mW of 850nm, 200mW of 660nm and 0mW of 455nm light via an electric diode energy source.
PBMT will be applied using the direct contact method with light pressure on the skin.
The PBMT application time will be 120 seconds per region and the total time will vary according to the number of regions to be treated.
Only the painful regions on that day will be treated (according widespread pain index [WPI] ), which can comprise a minimum of 3 and a maximum of 18 regions in total.
The dose used for applications during the treatment will be 60 Joules (J) per region.
The total dose might vary between patients and each session.
|
Placebo Comparator: Placebo PBMT
Placebo PBMT applied three times a week (interval of 48 hours approximately), for three consecutive weeks, totalling nine treatment sessions.
|
The placebo PBMT will be applied using MR5™ ACTIV PRO LaserShower Laser Therapy System, manufactured by Multi Radiance Medical (Solon, OH, USA).
The ACTIV PRO emits 905nm, and 850nm via an electric diode energy source with outputs to 0%.
The 660nm light via an electric diode energy source with outputs to >1% to appear like the active comparator.
PBMT will be applied using the direct contact method with light pressure on the skin.
The placebo PBMT application time will be 115 seconds per region and the total time will vary according to the number of regions to be treated.
Only the painful regions on that day will be treated (according WPI), which can comprise a minimum of 3 and a maximum of 18 regions in total.
The dose used for applications during the treatment will be 0 Joules (J) per region.
The sounds and signals emitted from the device as well as the information displayed on the screen will be identical, regardless of the type of treatment (active or placebo).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Degree of pain rating - change of TCP (tender point count)
Time Frame: 3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Reduction of the tender point count (TCP) where they have experienced pain as reported on Fibromyalgia Impact Questionnaire (FIQ).
|
3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain intensity - VAS
Time Frame: 3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Pain intensity will be measured by 0-100 standardized Visual Analog Scale (VAS).
|
3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Patient satisfaction - Likert Scale
Time Frame: 3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Patient satisfaction will be measured by 1-item Likert Scale.
The scale uses the following responses: very satisfied = 4; somewhat satisfied = 3; not very satisfied = 2; not at all satisfied =1.
Highest scores indicates better satisfaction.
|
3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Adverse events
Time Frame: 3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
|
Adverse events will be measured by report.
|
3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.
