To evaluate the use of two alternative picture archiving and communication systems (PACS) interface devices (a graphics tablet and a handheld controller) in clinical practice and on task-oriented exercises.
Eleven senior radiologists were prospectively evaluated. The participants used the two tested interface devices for 10 working periods each and answered a questionnaire to evaluate the ergonomics of this experience. The prevalence of work-related musculoskeletal discomfort with the standard PACS interface set (mouse-keyboard-recording device) and these two devices was assessed. Exercises evaluating image scrolling and selection, image zooming and panning, image windowing, performing measurements, and reporting were performed with the standard PACS interface set and with the two tested devices. The sitting posture and hand position were evaluated.
The general appreciation of the two alternative interface devices was considered to be similar to that of the standard interface set. The ergonomics of the handheld controller was considered to be slightly better than that of the standard interface set. The prevalence of musculoskeletal discomfort was 81%, 45%, and 18% for the standard interface set, graphics tablet, and handheld controller, respectively. With the graphics tablet and the handheld controller in 45% and 60%, respectively, there was a working posture change with respect to the standard interface set. The mean total exercise completion times of both tested devices were 27% higher than that of the standard interface set.
Despite the increase in completion time of the task-oriented exercises, the tested devices were well accepted and considered to be more comfortable than the standard set.
• Alternative PACS interface devices can be used as a substitute for the standard mouse-keyboard-recording device set with a potential improvement in work ergonomics and a reduction in work-related musculoskeletal discomfort.
评估两种替代的医学影像存档与传输系统（PACS）接口设备（图形输入板和手持控制器）在临床实践和面向任务的练习中的使用情况。
对 11 名资深放射科医生进行了前瞻性评估。参与者各使用两种测试接口设备 10 个工作周期，并回答一份问卷以评估该体验的人机工程学。评估了与标准 PACS 接口设置（鼠标-键盘-记录设备）和这两种设备相关的工作相关肌肉骨骼不适的患病率。使用标准 PACS 接口集和两种测试设备进行了评估图像滚动和选择、图像缩放和平移、图像窗口化、进行测量和报告的练习。评估了坐姿和手的位置。
两种替代接口设备的总体评价被认为与标准接口集相似。手持控制器的人体工程学被认为略优于标准接口集。肌肉骨骼不适的患病率分别为标准接口集 81%、图形输入板 45%和手持控制器 18%。与图形输入板和手持控制器相比，标准接口集分别有 45%和 60%的工作姿势发生变化。两种测试设备的平均总练习完成时间均比标准接口集高出 27%。
尽管面向任务的练习完成时间增加，但测试设备得到了很好的接受，并且被认为比标准设备更舒适。
•替代 PACS 接口设备可以替代标准的鼠标-键盘-记录设备组，从而有可能改善工作人体工程学并减少与工作相关的肌肉骨骼不适。
