Carpal tunnel syndrome (CTS) impairs sensation of a subset of digits. Although the effects of CTS on manipulation performed with CTS-affected digits have been studied using precision grip tasks, the extent to which CTS affects multi-digit force coordination has only recently been studied. Whole-hand manipulation studies have shown that CTS patients retain the ability to modulate multi-digit for...

OBJECTIVE To evaluate the incidence of carpal tunnel syndrome (CTS) in pregnancy through a validated and multiperspective assessment of CTS and to assess the course of carpal tunnel syndrome after pregnancy. METHODS During 2000-2001, the Italian CTS study group in 7 Italian centers studied the occurrence of CTS in women during the last period of pregnancy. The group enrolled and followed-up (...

OBJECTIVE To investigate the correlation of the ultrasonographic wrist-to-forearm median nerve area ratio (WFR) and cross sectional area of median nerve at the wrist (CSA-W) to the electrophysiologic severity in patients with carpal tunnel syndrome (CTS). METHOD One hundred and ten wrists electrophysiologically graded as mild, moderate, and severe CTS and 38 healthy controls underwent ultraso...

To determine the role of personal variables as risk factors for carpal tunnel syndrome (CTS) and their relationship to severity of nerve conduction abnormality, we studied 210 consecutive symptomatic CTS patients and 320 controls subjects without CTS symptomatology or known systemic disorders. The CTS group was classified according to the severity of nerve conduction changes. The risk factors f...

BACKGROUND Patients with carpal tunnel syndrome (CTS) sometimes report sensory symptoms outside the median nerve distribution. This study was designed to provide a more detailed assessment of these symptoms. METHODS Patients with clinical suspicion of upper limb neuromuscular lesions were divided into those with electrodiagnostic (EDX) evidence of CTS, and those without. CTS patients with sup...

Median nerve compression is a well-known cause of carpal tunnel syndrome (CTS). Yet, reasons why the most common idiopathic form of CTS develops in certain individuals are not well understood. To further understand the compressive mechanisms at work in CTS development, the authors used ultrasonographic imaging of the median nerve to evaluate 2 patients with CTS. Findings were compared to those ...

Objectives: This study aims to determine the bifid median nerve (BMN) frequency in patients with carpal tunnel syndrome (CTS) and to investigate the possible association between CTS and BMN in this patient population. Patients and methods: A total of 194 wrists of 131 patients in whom CTS was diagnosed clinically and electrophysiolog...

Objective: To determine prevalence of carpal tunnel syndrome (CTS) among poultry processing employees while taking into account non-occupational factors and assess any association between CTS prevalence and exposure groups. Methods:Performed a crosssectional survey to assess CTS (n = 318). A CTS case was defined as an employee with self-reported CTS symptoms, an abnormal hand symptom diagram, a...
