Terminal latency index, residual latency and median ulnar F latency difference in carpal tunnel syndrome are specific parameters for the diagnosis

Carpal tunnel syndrome is the most common compression neuropathy. This study was performed to determine the value of terminal latency index, residual latency and median ulnar F latency difference to investigate their sensitivity and specificity in the diagnosis of this syndrome.

We retrospectively determined the 160 patients. We evaluated the nerve conduction studies of patient and healthy arms. We recorded all nerve conduction study values.

Inclusion Criteria:

• Patients who had gone to electrodiagnostic study and diagnosed as carpal tunnel syndrome

Exclusion Criteria:

• any history of hereditary polyneuropathies
• acquired polyneuropathies
• surgery or local steroid injections for upper limbs or effect the study
• any history of fracture at the sites of stimulation or recording
