Objective: The purpose of this study was to validate the effectiveness of the newly designed (new) ultrasound device by comparing it with conventional (old) device through electromyography (EMG) signals, grip force and task time. Background: The prevalence rate of work-related musculoskeletal disorders (WMSDs) among sonographers is approximately four times higher that that of normal people. The awkward posture and over-exertion of upper extremities are the main risk factors for WMSDs. To reduce these risk factors, ergonomic designs such as adjustable control panels and transducer stations have been introduced for new ultrasound device. Method: A total of 10 obstetricians were participated in this study. To compare the scan stress between two devices (old and new), two types of experiments were performed: (1) Scanning task was carried out to measure muscle activity and grip force during scanning operations. (2) Positioning task was performed to quantify the load while obstetricians were moving the devices. Results: The new device showed significantly less muscle activities and grip forces than old device in scanning task. The task time of the new device was significantly shorter than that of the old one. Conclusion: Overall, the performance of the new device was evaluated more positive than that of old device. Application: Methods and findings of this study could be used to evaluate existing and newly developed ultrasound devices.
