Comparison of Ultrasound and Anatomic Landmark Techniques of the Ulnar and Posterior Tibial Nerves

Summary

The purpose of this study is to determine whether placement of stimulating electrodes over the ulnar nerve is important for proper delivery of current leading to stimulation of intrinsic hand muscles.

Detailed Description

Placement of stimulating electrodes over the ulnar nerve is important for proper delivery of current leading to stimulation of intrinsic hand muscles. Accuracy may be improved with a better description of the precise location of the ulnar nerve. There may be a simple fraction of the wrist width that can be utilized to assist the busy practitioner with accurate placement of the stimulating electrodes over the ulnar nerve. It is expected that the ulnar groove, when easily identified, will be an accurate estimate (within 10% of total wrist width) of the ulnar nerve location.
