Correlation of the Scratch Collapse Test (SCT) with Electromyography (EMG) and Nerve Conduction Study (NCS) in Evaluation of Upper Extremity Nerve Compression Syndrome

IRB Number


Trial Status

Open for Enrollment
Phase 1

Why is this study being done?

This study is being done to determine the clinical relevance of a non-invasive clinical exam (Scratch Collapse Test) with respect to electromyography (EMG) and nerve conduction studies (NCS) when diagnosing upper extremity nerve compression syndromes.

Who is eligible to participate?

New adult patients, males and females over the age of 18, who have been referred to the SIU Plastic Surgery Clinic for upper extremity nerve compression syndrome and, in the last 2 years, have had or are willing to have an EMG/NCS performed on one or both upper extremities.

What is involved?

Participants will be asked to complete a questionnaire and will be evaluated independently by 3 researchers (hand therapist, resident, and attending physician) using the Scratch Collapse Test. Previous EMG/NCS results will also be collected for comparison.

How long is the study?

The study will take place during the participant’s first clinic visit.
