An ergonomic case study for computer related tasks. Workers had to perform repetitive, computer-related tasks.

Task Prior to Abatement (Method Which Identified Hazard)

Increasing medical incidence rates of CTDs.

Up to 25 percent of employees were reported to have CTD problems.

Ergonomic Risk Factor for Computer Related Tasks (Posture)

Awkward posture was required to perform the task.

Ergonomic Solution (Administrative Controls)

  1. A proactive pilot program was developed to address worker needs and provide creative solutions.
  2. Ergonomics training courses were provided.

Ergonomic Solution (Engineering Controls)

  1. Ergonomically designed chairs were provided.
  2. Articulated keyboard and mouse writing surfaces were installed.
  3. Document holders were provided.
  4. Anti-glare screens were installed.
  5. Adjustable foot-nests were installed.
  6. Hand-free telephone headsets were provided.

Ergonomic Solution (Benefits)

  • All workers that perform the task now have reduced exposure to CTDs.
  • Reduction in workers’ compensation costs.

Ergonomic Solution (Cost)

Workstation modifications cost about $ 915 per worker.

Ergonomic Solution (Method Which Verified Effectiveness)

CTD related cases were decreased.


Having an immediate and positive response, the pilot program is being expanded to other departments.
