Trial Outcomes & Findings for Developing Brain Stimulation as a Treatment for Chronic Pain in Opiate Dependent (NCT NCT03681769)
NCT ID: NCT03681769
Last Updated: 2023-02-10
Results Overview
Based on pilot data, the investigators expect an interaction between treatment (DLPFC or MC rTMS) and time (Before vs. After rTMS) on reported painfulness using a quantitative sensory testing technique that determines thermal pain threshold.

Intermittent Theta Burst Stimulation (iTBS) to the Left dlPFC
For intermittent theta burst stimulation (iTBS) (Aim 1), participants will receive 20 trains of stimulation over the dlPFC (middle frontal gyrus) (F3) (each train: 3 pulse bursts presented at 5 hertz, 15 pulses/sec for 2 sec, 8 sec rest, 200 pulses/train; 110% resting motor threshold, MagPro; 600 pulses total) using a figure 8 coil (Coil Cool-B65 A/P).
iTBS to the left dlPFC: This will be delivered with the Magventure Magpro system; 600 pulses with the active sham coil (double blinded using the Universal Serial Bus (USB) key).

SECONDARY outcome
Timeframe: Patient reported pain/discomfort at 16 weeks.The investigators expect reductions in self reported pain assessment via a numeric pain rating scale when comparing active vs sham. Pain rating values will be assessed and reported through the duration of the study. Numeric Rating Scale (NRS) for pain has a range of 0 to 10 where 0=no pain/discomfort and 10=worst pain/discomfort imaginable. Higher scores mean more pain/discomfort.
