Comments on an article by Stetson et. al., entitled Observational Analysis of the Hand an Wrist: A Pilot Study (Applied Occupational and Environmental Hygiene, Vol. 6, No. 11, pages 927-937; see NIOSHTIC record NIOSH-00203124) were presented. Stetson et. al. had implied that relying on videotape analysis when performing an ergonomic analysis of risk factors for hand and wrist injuries was inappropriate because a camera could not adequately capture the complete range of hand and wrist postures used by workers when performing a job task. The authors state that they had successfully used videotaping for documenting biomechanical stressors in the workplace in more than 40 ergonomic hazard evaluations. A videotape provides a permanent record of work activities and conditions and can be considered to be generally equivalent to raw data collected by other techniques. Recording work activities on tape allows analysts to review the data at a later time. Videotape data can be easily reanalyzed, and offer the advantage of slow motion or real time playback. The authors disagree with Stetson et. al's. statement that a camera cannot adequately capture all hand and wrist postures during a work task, because modern video cameras are extremely light and portable and can be moved around to get clear views of hand and wrist positions.
