To compare pendulum test data obtained using an electrogoniometer with data obtained by videotape. The issue of video digitization error was also addressed.
The study compared pendulum test relaxation indices determined from data simultaneously collected using (1) a video (VID) camera and (2) an electrogonimeter (EG).
A spinal cord injury rehabilitation center.
Three persons with a spinal cord injury (SCI) exhibiting mild, moderate, and severe spasticity, respectively, and a fourth, non-SCI subject.
Relaxation index as a descriptor of lower limb muscle spasticity measured using the pendulum test.
Multiple-digitization of VID data did not affect the reliability of this technique. It was noted that reflective markers located on body landmarks resulted in more reliable data as opposed to markers placed on the EG. Both EG and VID data were accurate and reliable.
In the VID method, using one digitization by a single operator is sufficient. The appropriate placement of light reflector markers are on body points. EG and VID are both reliable, highly correlated, and interchangeable in measuring spasticity using the pendulum test.
比较使用电子测角仪获得的钟摆试验数据与通过录像带获得的数据。还探讨了视频数字化误差问题。
该研究比较了通过（1）摄像机（VID）和（2）电子测角仪（EG）同时收集的数据所确定的钟摆试验松弛指数。
一家脊髓损伤康复中心。
三名分别表现出轻度、中度和重度痉挛的脊髓损伤（SCI）患者，以及第四名非SCI受试者。
使用钟摆试验测量的作为下肢肌肉痉挛描述指标的松弛指数。
VID数据的多次数字化不影响该技术的可靠性。值得注意的是，位于身体标志点上的反光标记比放置在电子测角仪上的标记能产生更可靠的数据。电子测角仪和VID数据均准确可靠。
在VID方法中，由单个操作员进行一次数字化就足够了。光反射标记的合适放置位置是身体部位。在使用钟摆试验测量痉挛时，电子测角仪和VID都是可靠的、高度相关的且可互换的。
