The current study examines the effects of exercise, ergonomic modifications, and rest breaks on fatigue and musculoskeletal discomfort during computer tasks. For the purpose of this project, musculoskeletal discomfort is defined as a constellation of signs and symptoms that include muscle tension, paresthesia, pain, and/or physical strain in soft tissues and bones.
Static workstation workers frequently experience musculoskeletal discomfort which, according to a survey of the literature, may include muscle tension, muscle fatigue, paresthesia, pain, and/or physical strain in soft tissues and bones. The incidence of musculoskeletal discomfort in office workers like computer users is as high as 50%. In various studies on static workstation workers, musculoskeletal discomfort has been reported, either separately or in aggregate, in the neck, shoulders, elbows, wrists, hands, back, legs, buttocks, ankles, feet, and chest.
