Abstract

A new technique using a pre-calibrated magnetometer has been used to investigate the stability of the human body. Transducer coils were attached to a belt which was worn by the subject. Sway was measured over 30 s periods with eyes open and eyes closed. For 10 normal subjects, the mean sway speed was 3.6 +/- 0.9 mm/s with eyes open, and 5.3 +/- 1.5 mm/s with eyes closed. The mean ratio for eyes open to eyes closed was 0.68 +/- 0.10. The test was simple to perform and gave reproducible results.

摘要

一种使用预校准磁力计的新技术已被用于研究人体的稳定性。换能器线圈附着在受试者佩戴的腰带上。在受试者睁眼和闭眼的情况下，测量其30秒内的摇摆情况。对于10名正常受试者，睁眼时的平均摇摆速度为3.6±0.9毫米/秒，闭眼时为5.3±1.5毫米/秒。睁眼与闭眼的平均比值为0.68±0.10。该测试操作简单，结果具有可重复性。
