Sonographic Examination of Median Nerve Variations

Patients' general pain will be assessed with Visual Analog Scale (Global Pain), symptom severity and functional status will be assessed with Boston Carpal Tunnel Questionnaire, hand grip strength will be measured with dynamometer. Patient hand diagram will be marked according to patient's sensory symptoms. Median nerve cross-sectional area measurement at pisiform level with ultrasound, distal motor latency and sensory nerve conduction velocity with emg will be performed and recorded. Median nerve stiffness will be assessed with real-time elastography.
