Effects of Photobiomodulation Therapy Combined With Static Magnetic Fields in Patients With Fibromyalgia

2020-03-31 04:03:51 | BioPortfolio

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.

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

A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, HEADACHES, and occasionally DEPRESSION. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (FATIGUE SYNDROME, CHRONIC). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (From Adams et al., Principles of Neurology, 6th ed, p1494-95)
