Brief Summary

Fibromyalgia (FM) syndrome is defined by the American College of Rheumatology (ACR), as a chronic widespread pain and tenderness in at least eleven of eighteen specific tender points. Despite the increased understanding about FM, there is currently no cure for this syndrome and the treatment aims to provide symptomatic relief and improvement of physical capacities to perform daily tasks and quality of life. Evidence has suggest that photobiomodulation therapy (PBMT) can be used as monotherapy or as a supplementary treatment to other therapeutic procedures in patients with FM. However, the lack of consensus regarding therapeutic protocols hinders multicenter comparisons of the many clinical trials published. Further studies are needed to establish ideal parameters of PBMT to be used as a therapeutic tool in the management of fibromyalgia. Therefore, the aim of this project is to investigate the effectiveness of PBMT combined with static magnetic fields (sMF) in pain relief in patients with fibromyalgia.

Outcome Measures

Primary Outcomes (1)

  • Degree of pain rating - change of TCP (tender point count)

    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 Outcomes (3)

  • Pain intensity - VAS

    3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.

  • Patient satisfaction - Likert Scale

    3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.

  • Adverse events

    3 weeks (end of treatment) and 4 weeks after the conclusion of the treatment.

Study Arms (2)

Active PBMT

ACTIVE COMPARATOR

Active PBMT applied three times a week (interval of 48 hours approximately), for three consecutive weeks, totalling nine treatment sessions.

Device: Active PBMT

Placebo PBMT

PLACEBO COMPARATOR

Placebo PBMT applied three times a week (interval of 48 hours approximately), for three consecutive weeks, totalling nine treatment sessions.

Device: Placebo PBMT

Interventions

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.

Active PBMT

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).

Masking Details
A researcher will program the device (placebo or PMBT) and will be instructed not to inform the patients or other researchers as to the type of treatment (PMBT or placebo). Therefore, the researcher responsible for the treatment, the investigator and the outcome assessor will be blinded to the type of treatment being administered to the patients. 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 (placebo or PBMT).
