Study: NCT05745025

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Repeated Transcranial Magnetic Stimulation
Description: rTMS will be delivered using a commercially available magnetic stimulator (Rapid2, Magstim Inc., Eden Prairie, MN) with a figure-of-8 Air Film coil at 10 Hz. Coil orientation will be optimized for stimulation of the abductor pollicis brevis. Stimulation targeting will be identified using motor-evoked potentials (MEP) of the first dorsal interossei that will be monitored using electromyography (EMG) (Motion Lab Systems Inc., Baton Rouge, LA). The motor threshold (MT) of the muscle will then be identified by systematically adjusting the pulse intensity. The MT will be considered the lowest stimulation intensity at which 5 out of 10 MEPs have a peak-to-peak amplitude of at least 50 microvolts. rTMS will be performed at the identified optimal location at 10Hz using an intensity that is 80% of the MT. Pulse trains will be delivered for 10 seconds, with a 30-second rest for 20 repetitions.

Intervention type: DEVICE
Group type: SHAM_COMPARATOR
Intervention: Sham Repeated Transcranial Magnetic Stimulation
Description: Sham rTMS will be performed using the same methods as the active group, but a sham Air Film coil (Magstim Inc., Eden Prairie, MN) will be used. This coil looks and sounds like the active coil, but it does not deliver magnetic pulses.

Intervention type: OTHER
Group type: SHAM_COMPARATOR
Intervention: Rehabilitation
Description: Rehabilitation will consist of education, value-based goal setting, Graded Motor Imagery (GMI) (3 components described below), and graded activity. Subjects will complete activities at treatment sessions and be asked to perform certain treatment activities at home.~Week 1: Pain education, functional value-based goal setting, laterality training (first component of GMI), one task for graded activity (task-based on patient goals)~Week 2: Continue week 1 activity, add graded motor imagery (second component of GMI), progress 1st graded activity, and initiate 2nd graded activity exercise.~Week 3- Mirror therapy (third component of GMI), assess knowledge and update education as needed, progress graded activity 1 and 2, and add 3rd graded activity if appropriate based on patient goals.~Week 4- Continue with week 3 activities. Discuss experience with meditation and progress graded activity as tolerated
