本研究的目的是明确单位面积基因座长度（总基因座长度/摆动面积，L/A）作为稳定性测量参数的意义。我们检查了100名6至73岁的健康受试者。受试者站在一个稳定计上，眼睛睁开或闭上，记录身体重心的摆动一分钟。记录摆动模式和面积、轨迹总长度、L/A、Romberg系数和功率谱，并将L/A与其他参数进行关联。1) 20岁以下闭眼的L/A较低，20 ~ 50岁的L/A较高。60岁以后，这是一些个体差异。2)闭眼时的L/A值与睁眼时相似。3) L/A与摇摆面积和均方根呈负相关。4)L/A与基因座总长度和Romberg系数不相关。5) L/ a高的受试者在2 ~ 5 Hz范围内具有较高的密度功率谱。这些结果表明，L/A是本体感觉反射对站立姿势精细控制的一个参数。信用证在检查站立姿势的规则时是有用的。
The purpose of this study is to make clear the significance of locus length per unit area (total locus length/ area of sway, L/A) as a parameter of stabilometry. We examined 100 healthy subjects aged 6 to 73 years. The subject stands on a stabilometer with eyes open or closed, and the sway of the center of gravity of the body is recorded for one minute. The pattern and area of sway, total locus length, L/A, Romberg's coefficient and power spectrum are recorded, and the L/A and other parameters are correlated.1) The L/A with eyes closed was low in those less than 20 years of age, higher at age 20 to 50. After age 60, these were some individual differences.2) The values of L/A with eyes closed were similar to those with eyes open.3) The L/A showed a negative correlation with the area of sway and the RMS.4) The L/A was not related to total locus length or Romberg's coefficient.5) Subjects with a high L/A had a high density power spectrum at 2-5 Hz.These findings show that L/A is a parameter of the fine control of standing posture by proprioceptive reflexes. The L/A is useful in the examination of the regulation of stan-ding posture.
