Comparing Ultrasound and Landmark Techniques for Nerve Location
This study is comparing two ways to find the ulnar nerve (in your arm, near your elbow) and posterior tibial nerve (in your leg, near your ankle): using ultrasound or using measurements from specific body landmarks. The goal is to see if a simple measurement of your wrist width can help doctors accurately place stimulating electrodes over the ulnar nerve, which is important for testing how well your hand muscles work. We are looking for 40 English-speaking adults, aged 18 and older, who have not had ulnar nerve problems or surgery in that area. The main things we'll be looking at are your wrist width and how reliably that measurement helps locate the ulnar nerve.
- Study design
- This is an observational study involving 40 participants. It does not specify a phase.
- What's involved
- You would have measurements taken of your hands and feet/ankles, including photos and ultrasound measurements. The record does not specify the duration of participation.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary endpoints, wrist width and reliability of wrist width to locate the ulnar nerve, are measured at Baseline. No further follow-up is specified.

What this trial measures
- Wrist widthBaseline
Width of wrist will be measured with calipers and reported in inches
- Reliability of wrist width to locate ulnar nerveBaseline
Total number of times that the ulnar nerve, as identified with ultrasound, falls between 5-15% of the wrist width distance as measured from the ulnar side of the wrist
