Effectiveness of ultrasonography and nerve conduction studies in the diagnosing of carpal tunnel syndrome: clinical trial on accuracy

Abstract: BackgroundThe aim of this study was to evaluate the effectiveness of two diagnostic tests routinely used for diagnosing carpal tunnel syndrome (CTS)—ultrasonography (US) and nerve conduction studies (NCS)—by comparing their accuracy based on surgical results, with the remission of paresthesia as the reference standard.MethodsWe enrolled 115 patients, all of the female gender with a high probability of a clinical diagnosis of CTS. All patients underwent US and NCS for a diagnosis and subsequent surgical treatme… Show more

“…This study follows the research line on CTS from our institution and originated from a clinical accuracy trial based on ultrasound and nerve conduction studies effectiveness for CTS diagnosis. 16 Carpal tunnel anatomical variations were classified by Singer and Asworth 17 as type I, intrinsic, or intra-carpal tunnel, when found inside the carpal tunnel, and type II, extrinsic, or extra-carpal tunnel, when lying over the transverse carpal ligament. In our study, both intra- and extra-carpal tunnel anatomy, whether associated or not, were directly related to a probable clinical diagnosis of CTS.…”

“…However, ultrasound is the cheapest and the fastest diagnostic method of CTS. It is worth noting that, the above studies allow to find additional factors and changes within the wrist [6,26,30]. They enable the diagnosis of tendon sheathitis, ganglia, degenerative changes of the bones and necrosis of blood vessels.…”

“…10 Clinical assessments by physicians 11 are often supported by investigations that include nerve conduction studies (NCS), 12 to evaluate the nerve functionally, and an ultrasound assessment to identify if morphological alterations are evident. 13 However, both are typically undertaken in the specialist setting, and might not be available to all clinicians or patients. It has also been proposed that NCS can be used as a tool for predicting the development of CTS in the future, 14 but due to the cost and invasive nature of this investigation, it remains an impractical proposition.…”
