Subjects will be randomized to receive either real or sham rTMS, combined with rehabilitation. Subjects will attend 10 sessions over 4 weeks.~rTMS will be delivered at 10Hz using an intensity of 80% of the motor threshold. Pulse trains will be delivered for 10 seconds, with a 30-second rest for 20 repetitions. This will result in a total of 2,000 pulses of magnetic stimulation and will take approximately 20 minutes. There will be 10 rTMS sessions over the 4 weeks.~Sham rTMS will be delivered using the same method as rTMS, but the intensity will be lower, and the location of stimulation will be different.~Rehabilitation will include graded motor imagery, education, and graded functional activity. There will be 8 rehabilitation sessions over 4 weeks.~Outcomes will include questionnaires asking about pain and function, and either grip strength or leg press strength measurements.
Subjects with complex regional pain syndrome (CRPS) Type 1 will be randomized to receive repeated transcranial magnetic stimulation (rTMS) followed by rehabilitation or sham rTMS followed by rehabilitation. Treatment will last for 4 weeks, with the first week including 4 rTMS treatments and 2 rehabilitation treatments. Subsequent weeks will include 2 rTMS treatments followed by 2 rehabilitation treatments. Outcome measures will include pain ratings, PROMIS questionnaires, global rating of change, and grip strength or 1 repetition maximum leg press.
