The Feasibility of Using an HCU System for Investigating Ergonomic Injury Among Autoworkers

  Abstract
A preexperimental case study was conducted to determine the feasibility of imaging musculoskeletal changes in the anatomy of the elbow, which might be attributed to the use of a tool, commonly blamed for ergonomic injury among autoworkers. The aim of the feasibility study was to determine if a hand-carried ultrasound (HCU) system could be used to document any physiologic changes. An HCU system with a 12-MHz linear probe was taken portably to image a patient’s elbow before and after use of the tool. Increased vascular flow within the muscle tissue was noted, but no changes to the musculature were noted with sonography 1, 12, and 24 hours after prolonged use. The preexperimentally designed case study provided evidence that it was possible to document the elbow and forearm anatomy before and after tool use. Higher level evidence is needed on the ability to use an HCU system to detect musculoskeletal injury at the job site. The portability and high-resolution imaging provided by the specific HCU system used have potential for this innovative clinical application.
