Abstract Introduction: To assess the impact of powered stretchers in comparison to manual stretchers on both patient comfort and psychological benefits. Methods: A simulation study with 41 participants compared powered and manual stretchers. Sensors on participants collected X, Y, and Z-axis acceleration data during simulated patient movements. Participants experienced lifting/lowering and loading/unloading. Post-experiment surveys used a 7-point scale to rate comfort during stretcher movements. Results: The powered stretcher outperformed the manual stretcher in most lifting/lowering and loading/unloading movements, showing significantly lower RMS values, maximum accelerations, and minimum acceleration on each axis. In the Z-axis (vertical direction) acceleration, the powered stretcher demonstrated lower RMS (0.29 m/s² vs. 0.73 m/s², p Conclusion: Powered stretchers demonstrate significant advantages in reducing patient discomfort and vibrations compared to manual stretchers.
