The aim of this study was to investigate the relationship between different ultrasonographic indices used in patients with carpal tunnel syndrome and the level of tactile sensation.
The primary questions the study aimed to answer are:
• To what extent are the ultrasonographic parameters used in the diagnosis of carpal tunnel syndrome related to the level of sensory complaints in the patient?
Electrodiagnostic diagnosis of carpal tunnel syndrome with pain, numbness, burning, and tingling consistent with the median nerve dermatomal area lasting at least 6 weeks.

Patients with diagnosed CTS
Case-only
Cross-sectional
Nerve conduction studies
Diagnostic testUpper extremity nerve conduction studies including median-ulnar sensory and motor responses
Median nerve ultrasonography
Diagnostic testMedian nerve sonographic cross-sectional area and echogenicity measurements
Sensory testing
Diagnostic testtactile sensory tests
median nerve ultrasound
Median nerve maximum cross-sectional area measurement at the level of the carpal tunnel (mm²)
Pointed - blunt discrimination test
The patient is asked to distinguish between a pointed and a blunt tip by touching the median nerve dermatome.
Moved two point discrimination
The patient's finger is touched, starting from the distal tip and moving proximally, and the patient is asked to distinguish between one and two dots. The distance between the last pair of dots the patient can distinguish is noted in mm.
Fixed Two Point Discrimination Test
The patient's finger is touched starting from the distal tip and working proximally, and the patient is asked to distinguish between one and two dots. The distance between the last pair of dots the patient can distinguish is noted in millimeters.
Boston Carpal Tunnel Syndrome Questionnaire
The scale consists of an 11-question Likert-style symptom severity scale and an 8-question functional status scale. The total score is divided by the number of questions to calculate the score. Higher scores are associated with increased symptom severity and poorer functional status.
S-LANSS
A score of 12 or more out of 24 on a 7-question scale is considered in favor of neuropathic pain.
SF-12 (Short Form-12)
The SF-12 is a practical test consisting of seven questions that examine the life limits of the patient. The questionnaire includes questions aimed at understanding the physical and psychiatric effects. The results of the survey are calculated using two score calculation tools: physical (PCS-12) and mental (MCS-12). The highest score for the PCS-12 is 56.6, while the highest score for the MCS-12 is 60.7. Higher scores are comparable to a state of resilience and recovery, which can be compared to quality of life.
