Posted By Kieran J Duignan Roger Suitability of training aids you choose depends on your training objectives. Presumably, a model workstation can be used to convey something about biomechanics Other audio-visual aids may be enlisted to convey more challenging messages, e.g. a. people with irreparable musculo-skeletal injuries caused by failure to control RSI risks b. people with experience as expert witnesses to relate their experiences of how employees whose claims they have investigated have fared in claims c. research reports on patterns of outcomes of claims for RSI to indicate how the courts in the UK respond to claims of negligence by employee and/or employer While the use of such aids may be more complex than a mute, immobile workstation, they may have impact. How much the impact aligns with what you wish to convey is related largely to the quality of your managment of risks and to the alertness of trainees.
