Local Effects of Acupuncture and Nerve Conduction Studies

United States60 participantsStarted 2015-10

Plain-language summary

Thus study aims to characterize the local, nerve-specific effects of acupuncture on the median and ulnar nerves in the forearm, using nerve conduction studies and quantitative sensory testing. All participant will have carpal tunnel syndrome and the affected median nerve will be compared to the healthy ulnar nerve. Additionally, we aim to compare the local, nerve-specific effect of manual acupuncture to that of low-frequency electroacupuncture and of high-frequency electroacupuncture.
