Clinical Trial Summary

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.

Description:

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.

Intervention

Other:
• Exercise Without Rest Break
Participants in the exercise group will receive 'Exercise Breaks', of 10 minutes, twice a day during the work hours, in addition to the two 'Conventional Rest Breaks' of 15 minutes, twice a day during the work hours. Exercises include shoulder shrugs, neck tilts, wrist and forearm stretch, back and hip stretch, upper body stretch, hamstring stretch, upper back stretch, hand/finger stretch. Side stretch and neck stretch. Follow up 3 times a week for 5 weeks.
• Exercise With Rest Break
Participants in the exercise with rest break group will receive 'Exercise Breaks', of 10 minutes, twice a day during the work hours, in addition to the two 'Conventional Rest Breaks' of 15 minutes, twice a day during the work hours. Participants will also receive 'Supplemental Micro Breaks', of 30 seconds after every 15 minutes of working on a static computer workstation Follow up 3 times a week for 5 weeks.
• Rest Break
Participants in the rest breaks group will receive 'Supplemental Micro Breaks', of 30 seconds after every 15 minutes of working on a static computer workstation in addition to the two 'Conventional Rest Breaks' of 15 minutes twice a day during the work hours. Follow up 3 times a week for 5 weeks. During the rest breaks, participants will not perform any exercises.
