Biomechanical analysis

LINC Design investigated the functional and biomechanical benefits of a hand tool design. First a task analysis was conducted by observing the interaction of users with the two types of tools (one standard tool, the other optimized to improve ergonomics and comfort during use). An analysis of the difference in wrist rotation, flexion and elbow abduction was done by placing markers on bony prominences on the arm and wrist and tracking the movement of body-mounted markers during use with the two hand tool types. Digital video and motion tracking software was used to record and analyze the data. Results indicated a significant difference in wrist, elbow, arm and shoulder movement for the two hand tools.

LINC Design was able to confirm that the modified hand tool significantly decreased wrist, elbow, arm and shoulder movement. Based on the study results and an ergonomic assessment of the proposed hand tool design LINC Design was able to make recommendations to further improve the design. A final report was prepared and included test results, conclusions and design recommendations.
