Outcome Measures
Primary Outcomes (1)
Desires for Drug Questionnaire
This standardized questionnaire measures cravings for opioids. This scale includes a total of 13 items. Scoring is based on a 1-7 likert scale for each item. Specific items are assigned to one of three domains: desire, negative reinforcement, and control. A higher score indicates higher level of cravings. A lower score indicates a lesser level of opioid cravings, which is a better outcome. The primary outcome measure will be measured at various time points throughout the study to assess a change.

Study Arms (2)
rTMS group
EXPERIMENTALActive rTMS treatment will be delivered at 10 Hz, 100% resting motor threshold, 2000 pulses delivered in five seconds per train with 10-second intra-train pause, delivered once daily five days per week, Monday through Friday for 10 days (10 total treatments). This protocol is adapted from Shen and colleagues (2016), who did not report any adverse events. Liu and colleagues (2020) also used the same protocol and only reported mild side effects of dizziness, headache, and insomnia, which resolved by the 30-day follow-up. However, it is unclear whether these side effects resolved sooner than the 30-day follow-up.
Placebo Group
SHAM COMPARATORThe control group will undergo the same seat positioning and comfort measures but will not have a resting motor threshold determination. The coil will be turned 90 degrees counter-clockwise, and the side of the coil will rest on the scalp over the area of the skull corresponding to the motor cortex, so the participant will feel the coil making contact. The same treatment protocol in the active rTMS group will be initiated to mimic the sound of rTMS treatment, though no pulses will be delivered to the participant because of the coil rotation.
