The postural stability of 30 normal subjects in the age range 15 to 64 years was measured on five separate occasions, using the sway magnetometry technique, to determine the day-to-day repeatability of this measurement technique. On each occasion the pathlength and area enclosed by movement of the hips in a horizontal plane were measured over two 30 s periods with eyes open and eyes closed, with subjects standing on a firm base. Day-to-day repeatability had a standard deviation of 14% for pathlength and 42% for area. Neither the age nor the sex of the subject had any demonstrable effect on the results.
为了确定摇摆磁力测量技术测量结果的每日可重复性，使用该技术在五个不同时间点测量了30名年龄在15至64岁之间的正常受试者的姿势稳定性。每次测量时，受试者站在坚实的基础上，在睁眼和闭眼状态下，分别在两个30秒时间段内测量其在水平面内臀部运动所围成的路径长度和面积。路径长度的每日可重复性标准差为14%，面积的每日可重复性标准差为42%。受试者的年龄和性别对结果均无明显影响。
