Brief Summary

Fibromyalgia is a common disorder affecting approximately 2% of the Canadian population. Patients diagnosed with fibromyalgia commonly present with chronic, widespread pain as well as fatigue, depression, mood disturbances, and cognitive symptoms. As a result, fibromyalgia has a negative impact on the patient's quality of life, and a negative financial impact for them, society, and the healthcare system, through lost wages and delayed diagnosis. Therefore a more direct and conclusive method of diagnosis is needed. Recently, fibromyalgia diagnosis has been based on the modified American College of Rheumatology Preliminary Diagnostic Criteria for fibromyalgia. To assist with diagnosis, recent evidence shows that compared to healthy people, people with fibromyalgia present with differences on functional MRI (fMRI) whole brain scans, as well as differences in a functional blood biomarker challenge test, known as fm/a. The fm/a determines the function of the immune system in response to a stimulus, and has been used previously to show that people with fibromyalgia have a severely blunted immune response. Despite the number of treatment options available, interventions for chronic pain remain largely ineffective. In light of its demonstrated effectiveness, safety, and ease of use in previous studies, radial shockwave therapy (RSWT) has been selected for inclusion in the present study. The main objective of this study is to determine the efficacy and effect of RSWT compared to placebo on the symptoms frequently reported in association with fibromyalgia. In addition, the fm/a and brain activity associated with pain patterns (fMRI) may assist in early diagnosis and prediction of treatment success in patients with fibromyalgia.

Outcome Measures

Primary Outcomes (1)

  • Change in Visual Analog Scale (VAS) Pain Score from Baseline to 6 Weeks

    Subject pain will be rated using a VAS by the participant for the 3 most painful regions.

    Measured pre-treatment (baseline) and post-treatment (at 6 weeks)

Secondary Outcomes (4)

  • Focus Group Qualitative Themes Identified from Transcripted Survey Responses

    Post-treatment (at 6 weeks)

  • Change in Pressure Pain Threshold from Baseline to 6 Weeks

    Measured pre-treatment (baseline) and post-treatment (at 6 weeks)

  • Change in Blood Biomarker fMA Test from Baseline to 6 Weeks

    Measured pre-treatment (baseline) and post-treatment (at 6 weeks)

  • Change in Functional Magnetic Resonance Imaging from Baseline to 6 Weeks

    Measured pre-treatment (baseline) and post-treatment (at 6 weeks)

Study Arms (2)

Group 1 - Radial Shockwave Therapy Group

EXPERIMENTAL

Participants in Group 1 will receive RSWT to the most painful spot within each of the 3 most painful regions as described by the participant. Treatments will be spaced one week apart over a 5 week period of time. 5 weekly sessions with treatment to the painful areas will be undertaken with 500 shocks (1.5 bar, 15 Hz), then 1000 shocks (2 bar, 8 Hz), and finally 500 shocks (1.5 bar, 15 Hz) to the most painful spot.

Device: Radial Shockwave Therapy

Group 2 - Placebo Group

PLACEBO COMPARATOR

Participants in Group 2 will receive a placebo treatment with a soft rubber cap applied to the applicator, leaving air between the transmitter and the cap and the participant's skin so that no shockwave will be generated nor applied to the participant's skin. Treatments will be spaced one week apart over a 5 week period of time. 5 weekly sessions with placebo treatment to the painful areas will be undertaken with 2000 placebo shocks (15 Hz) producing an audible sound but no therapeutic dosage to the most painful spot. Upon completion of the placebo treatment, participant's will be offered the experimental treatment but this data will not be used for comparison and analysis.

Other: Placebo Comparator: Group 2 - Placebo Group

Interventions

5 treatments in total scheduled weekly; RSWT to the painful areas will be undertaken with 500 shocks (1.5 bar, 15 Hz), then 1000 shocks (2 bar, 8 Hz), and finally 500 shocks (1.5 bar, 15 Hz) to the most painful spot within each of the 3 most painful regions as described by the participant.

Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Men and women aged 18-60 years
  • diagnosed with FM by a physician based on ARC Diagnostic Criteria\\
