The aim of this cross-sectional study is to evaluate muscle strength in female patients with carpal tunnel syndrome (CTS) who have only sensory involvement detected on electromyography. Muscle strength will be assessed using the "Lafayette Manual Muscle Tester®".
The main questions of the study are:
1. Is there a difference in muscle strength between healthy individuals and female patients with carpal tunnel syndrome? 2. Is there a difference in muscle strength between female patients with carpal tunnel syndrome who have only sensory involvement and those who have both sensory and motor involvement? 3. Are there differences in the strength of thumb palmar abduction and adduction, radial adduction and abduction, thumb flexion, extension and opposition, and flexion of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints of the fingers between these groups?
The investigators will measure the muscle strength associated with these movements using the "Lafayette Manual Muscle Tester®" in order to objectively evaluate motor involvement in female patients with carpal tunnel syndrome and to compare muscle strength between healthy individuals and patients with different degrees of electrophysiological involvement.

Case-control
Cross-sectional
Not listed
Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ)
A questionnaire consisting of 11 questions assessing symptom severity and 8 questions assessing functional status. Higher scores indicate greater disease severity. The Turkish version of the questionnaire has demonstrated validity and reliability. Numerical Rating Scale (NRS), A scale in which patients rate their pain on a numerical scale from 0 to 10. Higher scores indicate greater pain intensity.
Phalen Test
The patient is asked to flex both wrists and hold the dorsal surfaces of the hands together for 60 seconds. The test is considered positive if pain or paresthesia occurs in the areas innervated by the median nerve, including the thumb, second and third fingers, the radial half of the fourth finger, or the forearm.
Durkan Test
The patient's forearm is placed in supination, and pressure is applied over the median nerve between the thenar and hypothenar eminences for 30 seconds. The test is considered positive if paresthesia or pain is experienced.
Tinel Test
In the symptomatic hand, the distal portion of the palmaris longus tendon near the palmar aspect of the wrist is gently percussed with a neurological reflex hammer. The test is considered positive if paresthesia or pain is experienced.
