[Symptoms and upper limb work-related musculo-skeletal disorders among 173 supermarket cashiers].

Background: Cashiers in supermarket chains have long been considered at risk for the development of work related musculo-skeletal disorders of the upper limbs (UL-WMSDs). The aim of this study was to assess the prevalence of UL-WMSDs among workers operating supermarket cash tills and, after clinical tests, their frequency.

Methods: A standardized questionnaire was given to a random group of 173 workers in order to collect information regarding symptoms in the upper limbs (pain and parasthesia).
