Upper extremity work related musculoskeletal disorders such as tendinitis and carpal tunnel syndrome are rampant in many industries. Evaluation of workstation ergonomics is a valuable tool in addressing this problem. The StrainAnalysis program, based on the "strain index equation", a mathematical model for prediction of job risk, simplifies this process.

Small or medium sized companies that do not have professional ergonomics or industrial hygiene staff may find this program very useful for performing initial surveys of their workstations. It is designed to be usable with little formal training. The "Help" system includes detailed information, and prompts within the program help the user enter the appropriate data. The results of the strain index calculation provide not only the strain index itself, but also "multipliers" that point to specific job characteristics which need to be addressed in ergonomic remediation. (This system does not address vibration related issues, or problems occurring above the elbow.)
