Brief summary
The aim of the study is to evaluate the prevalence of bifid median nerve in patients diagnosed with carpal tunnel syndrome (CTS) and whether it has a higher prevalence in CTS patients than in asymptomatic individuals, and to evaluate the characteristics of the bifid median nerve found and whether median nerve variations are predisposing factors in the development of CTS.
Detailed description
Patients diagnosed with carpal tunnel syndrome electrophysiologically who applied to Etlik City Hospital physical therapy outpatient clinic will be included in the study.There are no sensitive groups.The research period was determined as 1 year.The sample size was done using G Power 3.1.9.4 statistical power analysis program for Windows.Based on the study conducted by Walker FO et al., the number of patients that would provide a significant difference (with a margin of error of 5% Type 1 and 20% Type 2, a study power of 80% and a confidence interval of 95%) was found to be 129 patients in total.Demographic and clinical characteristics of patients who meet the inclusion criteria and fill out the Informed Consent Forum will be recorded.General pain of the patients will be evaluated with the Visual Analogue Scale (Global Pain), symptom severity and functional status will be evaluated with the Boston Carpal Tunnel Questionnaire, and hand grip strength measurement will be evaluated with a dynamometer.The patient hand diagram will be marked according to the patient's sensory symptoms.Median nerve cross-sectional area will be measured at the pisiform level with ultrasound, and distal motor latency and sensory nerve conduction velocity will be measured with EMG and recorded.Median nerve stiffness will be evaluated by real-time elastography.
Interventions
DIAGNOSTIC_TESTelastography,usg
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale(VAS) | This evaluation will be made and recorded at the beginning | The VAS used for pain assessment consists of a line drawn in the form of a ruler,and numbers from 0 to 10(with 0 as ''no pain'' and 10 as ''unbearable pain'') were asked to score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Boston Carpal Tunnel Questionnaire | This evaluation will be made and recorded at the beginning. | symptom severity and functional status scale |
| Dynamometer | This evaluation will be made and recorded at the beginning. | Hand grip strength measurement test |
| Ultrasound | This evaluation will be made and recorded at the beginning. | Median nerve cross-sectional area measurement at the pisiform level. |
| Real-time elastography. | This evaluation will be made and recorded at the beginning. | Median nerve stiffness will be evaluated by real-time strain/sheer elastography. |
