Neurophysiology of Fibromyalgia

rTMS is a non-invasive, non-painful procedure used to relieve chronic pain and promote short-term changes. The abductor pollicis brevis (APB) muscle of the left motor cortex will be targeted using neuronavigation software. 1500 pulses will be delivered at 10 Hz stimulation. Stimulation will be delivered at 80% of the resting motor threshold obtained from the right APB muscle. The delivery of rTMS requires 11 minutes in total.

A sham coil will be utilized for the sham rTMS condition. It is important to note that from the participant perspective, the sham stimulation will feel and sound identical to active. The location and all other parameters of Sham rTMS will be identical to Active rTMS.
