Brief Summary

The purpose of this study is to assess the effects of tDCS in combination with TUS for the treatment of pain in subjects with Carpal Tunnel Syndrome. The investigators hypothesize that there will be a decrease in pain levels with active stimulation, when compared to sham stimulation.

Eligibility Criteria

Inclusion Criteria: 1. Able to provide informed consent to participate in the study 2. Subjects between 18 to 80 years old 3. Having symptomatic CTS spreading within or beyond the median nerve distribution (demonstrating 'extra-median spread'), involving at least 1 wrist, with chronic pain as defined by International Association for the Study of Pain (existing pain for at least 6 months and having pain on at least half the days in the past 6 months with an average of at least a 3 on a 0-10 VAS scale). 4. Pain resistant to first line therapies of chronic pain (pain still present at lower levels most of the time following therapy) 5. Must have the ability to feel pain as self-reported. Exclusion Criteria: 1. Subject is pregnant 2. Contraindications to tDCS+TUS: 1. intracranial metal implant 2. implanted brain medical devices 3. History of alcohol or drug abuse within the past 6 months as self-reported 4. Use of carbamazepine within the past 6 months as self-reported 5. Suffering from major depression (with a PHQ-9 score of ≥20) 6. History of neurological disorders involving stroke, brain tumors, or epilepsy with residual neurological symptoms as self-reported (note patients will also be evaluated via EEG at baseline about 1 week prior to stimulation and any patient showing abnormal EEG activity will be removed)) 7.
