A Study to Examine Short Segmental Electrical Stimulation "inching" of the Ulnar Sensory Nerve in Detecting Mild Ulnar Neuropathies at the Elbow
Overview
Tab Title Description
Study type
ObservationalDescribes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
This study specifically aims to examine whether a technique of ulnar sensory “inching” nerve conduction study may be useful in localizing the site of compression in mild ulnar neuropathies, where standard conduction studies are unable to precisely localize the lesion.
Participation eligibility
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Inclusion Criteria:
- Clinical history compatible with ulnar neuropathy, including numbness in the medial hand and/or 4th and 5th digit
- No history of other upper extremity mononeuropathy (e.g. carpal tunnel syndrome) or cervical radiculopathy
- No history of surgery involving the ulnar nerve (e.g. nerve transposition)
- Normal ulnar motor and sensory amplitude at distal sites of stimulation(distal ulnar motor amplitude >6.0 mV, distal ulnar sensory (antidromic technique) amplitude > 10 uV)
- Age > 18 years
Exclusion Criteria:
- Prior history of CTS, brachial plexopathy, or C8-T1 cervical radiculopathy
- Findings of other neuromuscular process on EMG (median neuropathy, brachial plexopathy, C8-T1 radiculopathy, etc.)
- Previous ulnar nerve surgery
- Low ulnar motor or sensory amplitudes at distal site of stimulation
- Bilateral symptoms of ulnar neuropathy
