Distal pain and carpal tunnel syndrome diagnosis among cashiers: a longitudinal study.

Objective: To estimate in a longitudinal study the yearly incidence of carpal tunnel syndrome (CTS) in a cohort of women working as cashiers.

Method: A total of 198 cashiers, belonging to a cohort investigated in 2011-2012 for arm pain, were screened for re-assessment in 2015 (at least 40 months from the first examination), and 156 women had complete demographic, personal and working data allowing to be included in this study. On the basis of self- and clinician-administered questionnaires investigating the presence of CTS, all symptomatic patients underwent clinical and neurophysiological [nerve conduction studies (NCS) of median and ulnar nerves] assessments.

Ambulatory phonation monitoring in a sample of 92 call center operators.

Objectives: The voice is a primary work tool for call center operators, but the main risk factors for voice disorders in this category have not yet been clarified. This study aimed to analyze the vocal behavior in call center operators and search for correlations between the daily voice dose and the self-perceived voice-related handicap.

Study Design: Prospective.
