Transcranial Magnetic Stimulation for Chronic Scrotal Content Pain

Resting motor threshold will be established by first finding the area of the motor cortex associated with visible twitch of the right abductor pollicis brevis (APB). Parameter Estimation by Sequential Testing (PEST) will be conducted to quantify resting motor threshold using visible APB twitch. The left dorsolateral prefrontal cortex (DLPFC) will be located using the Beam F3 method and marked with a felt-tipped marker on the scalp. TMS will be delivered over left DLPFC at 110% of resting motor threshold at 10Hz (5-seconds-on; 10-seconds-off) for 15 minutes per session (3000 pulses), 3 sessions each day (30-minute rest in-between sessions), for 3 days (within 5 consecutive days; a total of 27,000 pulses).
