We are recruiting participants aged 18-75 years to take part in a study of fibromyalgia. We'll be examining its potential biomarkers and neural stimulation treatments!


You will be asked to fill out a series of questionnaires, donate a saliva sample, and receive Controllable-Pulse-Parameter Transcranial Magnetic Stimulation (cTMS) pulses to the motor areas of the brain.


Your time participating will involve an orientation session of approximately 3 hours, 1 session for Experiment A of approximately 2 hours, and 10 sessions in Experiment B of approximately 45 minutes over the course of two weeks. In appreciation of your time, you will receive reimbursement of up to $20 per lab visit.

Our Goals:

1) Examine potential biomarkers that can be used to effectively diagnose fibromyalgia.

2) Examine the effectiveness of non-invasive brain stimulation in reducing pain experienced by people with fibromyalgia.

Experiment Breakdown, Compensation, and Timeline:


1 session in 1 day

~2.5 hours total

- TMS Demo 

- Consent

- Questionnaires

- Electroencephalogram (EEG)

Experiment A

1 session in 1 day

~2 hours total

$80 compensation

Saliva sample for genotyping

- Questionnaires

- Sensorimotor tasks

- Transcranial Magnetic Stimulation (TMS)

Experiment B

10 sessions in 2 weeks

~45 minutes per session

$12/visit or parking pass

- Questionnaires

- Sensorimotor tasks

- Controllable-Pulse-Parameter  Transcranial Magnetic Stimulation (cTMS)


Participants can choose to only participate in Experiment A alone, or, can choose to partake in both Experiment A and B. Participants must take part in Experiment A to qualify for Experiment B.

What is cTMS?

Controllable Pulse Parameter Transcranial Magnetic Stimulation (cTMS) is a non-invasive technique used to stimulate certain brain cells from the outside. The cTMS works by generating a magnetic field through it's coils, which induces an electric current stimulating certain brain cells.

How is this study using cTMS?

We believe that there are many potential causes of Fibromyalgia thought to be related to irregularities of neural impulses in the brain. This study aims to use cTMS to change the activity of neurons in the brain, resulting in a reduction of pain!

How our Research and YOUR HELP can help People with Fibromyalgia:

Identifying biomarkers for fibromyalgia can make diagnosing the condition easier and less ambiguous!

If brain stimulation effectively reduces pain, then it can be explored further as a treatment option.

This research is the first of its kind!
