This study will include 20 patients aged 18-75 years who have been diagnosed with carpal tunnel syndrome (CTS) based on electrophysiological examinations performed within the last three months, as well as 20 healthy volunteers without a CTS diagnosis. Sociodemographic data such as age, gender, height, weight, and BMI will be recorded. Pinch grip strength will be evaluated using a Jamar pinch meter, and hand grip strength will be assessed using a Jamar dynamometer. Ultrasound will be used to measure the cross-sectional area and thickness of the thenar muscles as well as the cross-sectional area of the median nerve. Additionally, previous electrophysiological examination results will be recorded for the CTS patients.

Inclusion Criteria:

• Patients aged 18-75 years.
• Diagnosed with carpal tunnel syndrome based on electrophysiological examination within the last 3 months.
• Healthy volunteers without a diagnosis of carpal tunnel syndrome.
• Volunteered to participate in the study.
