The Polhemus Fastrak short-range miniature transmitter and mini-receivers allow wrist motion to be measured continually in three dimensions, registering patterns of motion, which until now were difficult to quantify. The current study aimed to determine the applicability and repeatability of the Fastrak system when assessing wrist movements during a set protocol of activities. The device was found to be easy to use and repeatable; the Fastrak system showed a mean error of up to 3 degrees in all movements tested. Its assessment of range of motion correlated with the results in the literature. The Fastrakv system was suitable for continuous registration of movements during the performance of set tasks in either of the wrists. It has the potential to be used for documentation of wrist motion in clinics for various pathologies and for assessing outcomes in wrist surgeries.
Polhemus Fastrak短程微型发射器和微型接收器能够持续测量手腕在三维空间中的运动，记录运动模式，而这些运动模式至今仍难以量化。本研究旨在确定Fastrak系统在评估一组特定活动中的手腕运动时的适用性和可重复性。结果发现该设备易于使用且具有可重复性；在所有测试运动中，Fastrak系统的平均误差高达3度。其对运动范围的评估与文献中的结果相关。Fastrak系统适用于在执行特定任务时对任一手腕的运动进行连续记录。它有潜力用于记录各种手腕病变在临床中的运动情况，并评估手腕手术的结果。
