The goal of this observational study is to test the new kind of ultrasound-based measurements in patients with carpal tunnel syndrome. The main questions it aims to answer are:
- Do the measurements of the size of the median nerve at the point where it is maximally compressed accurately diagnose carpal tunnel syndrome?
- May these measurements accurately tell how severe is the carpal tunnel syndrome?
Participants will be asked to:
- Undergo conduction studies of median and ulnar nerve.
- Undergo ultrasound of the median nerve.
- Fill out the Boston carpal tunnel questionnaire and a demographic questionnaire.
Researchers will compare the group of patients with carpal tunnel syndrome with healthy volunteers to see if respective measurements differ significantly between groups.

Patients with CTS
Patients referred to the Electromyographic Laboratory of the Department of Neurology at the Jagiellonian University Medical College, Cracow, Poland with symptoms suggestive of CTS (numbness of the hand, present or accentuated in the night, reduced hand dexterity) with CTS confirmed in NCS or US.
|
Diagnostic Test: Nerve conduction study
Nerve conduction study of median and ulnar nerve together with sensory comparative methods on the affected side (sides). Diagnostic Test: Ultrasound Ultrasound of the median nerve on the affected side (sides). |
Healthy controls
Subjects referred to the Electromyographic Laboratory of the Department of Neurology at the Jagiellonian University Medical College, Cracow, Poland for investigation towards tetany, with no or only weak signs of tetany in electromyography.
|
Diagnostic Test: Nerve conduction study
Nerve conduction study of median and ulnar nerve together with sensory comparative methods on the affected side (sides). Diagnostic Test: Ultrasound Ultrasound of the median nerve on the affected side (sides). |
