Repetitive exertions have been shown to be positively associated with the prevalence of work-related musculoskeletal disorders. However, there is not agreement on acceptable levels of repetition, partly due to the absence of objective methods for quantifying repetition in diverse types of hand work. Previous studies have attempted to quantify repetition based on production standard data, i.e. cycle time and parts produced. However, such methods are difficult to apply to certain tasks. In this tudy, three methods of quantifying repetition were compared: traditional time study, electromyography (EMG), and a newly-developed observational rating system.
