1.1 The purpose of this practice is to discuss the potential benefits and risks of exoskeletons when used by workers during the Return to Work (RTW) process following an injury or illness, and to provide guidance to anyone considering their use during the modified/transitional duty period. The primary objectives of any exoskeleton used in a RTW capacity are to facilitate the natural healing process, prevent an exacerbation of an existing injury or illness, prevent further injuries or illnesses from developing, reduce the number of modified/transitional duty days, reduce the number of visits to healthcare providers for medical treatments, and assist the worker with return to full duty without restrictions. The exoskeleton must not aggravate the original injury or illness, nor cause a secondary injury or illness. Successful RTW constitutes an injured worker''s ability to tolerate all of the demands of his/her job without reinjury, perform essential job functions, or return to work as per the decisions and directions of the worker''s physician and employer. In some cases, workers may continue to use the exoskeletons after full duty RTW for risk reduction, injury prevention, or to continue to perform essential job functions. Exoskeleton usage that continues beyond full duty RTW for these purposes is beyond the scope of this particular standard practice.
