Revised Strain Index: Date: Task: Company: Supervisor: Dept: Evaluator

The Revised Strain Index is a tool for assessing upper extremity exposure to risk factors in the workplace. It includes measurements of exertion intensity, hand/wrist posture, and duration of tasks to evaluate safety levels. A score below 10 indicates a probably safe job, while a score above 10 suggests potential hazards.
