Summary

This study will investigate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) and a sensorimotor training task to treat symptoms of pain in patients with complex regional pain syndrome (CRPS). rTMS is a non-invasive technique that involves delivering magnetic pulses in rapid succession over the area of the brain that controls movement. The sensorimotor training task involves non-invasive nerve stimulation used to cue a participant to complete motor actions. The purpose of this study is to determine whether recruitment is feasible in this patient population and patients maintain adherence to the intervention. In addition, the investigators want to determine whether rTMS combined with sensorimotor training is an effective intervention to alleviate symptoms of pain in patients with CRPS.

Interventions

DEVICE

Repetitive transcranial magnetic stimulation

Repetitive transcranial magnetic stimulation (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. 2000 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 \~ 11.5 minutes in total.

OTHER

Sensorimotor training

Sensorimotor training is a non-invasive, non-painful procedure using nerve stimulation to cue motor action. Nerve stimulation is applied the second through the fifth digit and the median nerve at the wrist. This stimulation is used to cue a motor action. The number of stimulations will indicate the amount of movements. For example, two pulses of stimulations to the index finger would require two flexion and extension actions with the index finger. Once the stimulation occurs, the participant will flex and extend the corresponding area where the nerve stimulation was felt. This will take \~ 30 minutes to complete.
