Description: Employers introduced video display terminals (VDTs) into the work setting to increase the productivity of workers and to increase control over the production process. Little consideration seemed to be given to the impact on workers' health. Published research regarding interventions for the health problems of VDT operators was lacking. The purpose of this study was to determine if VDT operators who participate in a computer-assisted intervention on proper posture and exercises will have (a) fewer complaints of musculoskeletal discomfort; (b) greater trunk and neck flexibility; (c) greater abdominal and scapula muscle strength; and (d) higher job satisfaction than VDT operators who did not participate in the intervention. Neuman's Systems Model was used to guide the study.

A quasi-experimental design was used with 31 operators in the intervention group and 28 operators in the control group. Intervention group subjects completed a 5-week, 50 session computer-assisted intervention program.

Data collection for physical characteristics and the dependent variables of musculoskeletal discomfort, trunk and neck flexibility, abdominal and scapula muscle strength, and job satisfaction was conducted through work-site visits. Flexibility and muscle strength were obtained by clinical measures. Musculoskeletal discomfort and job satisfaction were measured with self-report questionnaires.

Operators participating in the computer-assisted intervention had significantly higher trunk and neck flexibility and scapula muscle strength than the control group. No statistically significant differences between groups were found for musculoskeletal discomfort, job satisfaction, and abdominal muscle strength.

Implications for nursing practice and education included: use of CAI exercises for VDT operators needs to be promoted and supported by occupational health professionals and because computers are utilized extensively today, nursing curricula at the undergraduate and graduate levels should include information about the musculoskeletal complaints of VDT users and the effectiveness of the exercises for improving trunk and neck flexibility and scapula muscle strength.
