A study of interpolation method in diagnosis of carpal tunnel syndrome Alireza Ashraf1,2, Abbas Daghaghzadeh1,3, Mahshid Naseri1,2, Aref Nasiri1,2, Maryam Fakheri1,2 Department of 1Physical Medicine and Rehabilitation, 2Burn Research Center, 3Geriatric Research Center, Shiraz University of Medical Sciences, Shiraz, Iran Abstract Context: The low correlation between the patients’ signs and symptoms of carpal tunnel syndrome (CTS) and results of electrodiagnostic tests makes the diagnosis challenging in mild cases. Interpolation is a mathematical method for finding median nerve conduction velocity (NCV) exactly at carpal tunnel site. Therefore, it may be helpful in diagnosis of CTS in patients with equivocal test results. Aim: The aim of this study is to evaluate interpolation method as a CTS diagnostic test. Settings and Design: Patients with two or more clinical symptoms and signs of CTS in a median nerve territory with 3.5 ms  ≤  distal median sensory latency

Test-retest reliability of transcarpal sensory NCV method for diagnosis of carpal tunnel syndrome.
Carpal Tunnel Syndrome (CTS) is the most frequent entrapment neuropathy affecting the upper extremity. There are a variety of electrodiagnostic methods available for documenting median neuropathy in CTS. In some studies, determining the sensory NCV a

Pathophysiology of carpal tunnel syndrome.
Carpal tunnel syndrome (CTS) is the most common median nerve neuropathy, accounting for 90% of all neuropathies. Carpal tunnel syndrome presents in 3.8% of the general population, with a higher prevalence among women. There are several risk factors a

Carpal tunnel syndrome.
Carpal tunnel syndrome is the commonest entrapment neuropathy and is due to combined compression and traction on the median nerve at the wrist. It is often idiopathic. Although spontaneous resolution is possible, the usual natural evolution is slow p

Carpal Tunnel Syndrome in Hypothyroidism.
Carpal Tunnel Syndrome (CTS) is an entrapment neuropathy that occurs due to compression of median nerve in the carpal tunnel and hypothyroidism is one of the important causes of CTS.
