To investigate the efficacy of posturography with inclinometer and platform with global bottom to make the subjects contact the ground almost at one point in the evaluation of body balance function.
The body balance function of 100 normal persons, 50 males and 50 females, aged 21 approximately 50, and 87 patients with peripheral vertigo due to semicircular canal palsy, aged 20 approximately 60, was measured with a new type of posturograph with inclinometer and platform with global bottom developed by the authors. The subjects with an inclination-sensor being fixed at the waist were asked to adopt four postures during the measurement: standing on the ground with eyes opened (test 1), standing on the ground with the eyes closed (test 2), standing on the platform with the eyes opened (test 3), and standing on the platform with the eyes closed (test 4).
The measurement of the normal persons showed the average values of body sway angle velocity were 0.57 +/- 0.24 d/s in test 1, 0.70 +/- 0.18 d/s in test 2, 1.16 +/- 0.32 d/s in test 3, and 2.67 +/- 0.70 d/s in test 4. Sixty-two out of the 87 patients (71.26%) showed abnormality in one or more than one of the 4 tests with a value more than x +/- 2s of the normal value, among them 7 showed abnormal value in test 1, 14 in test 2, 16 in test 16, and 56 in test 4. Two weeks after the onset of vertigo, 55 out of the 87 patients showed abnormal values by this examination.
Posturography with inclinometer and platform with global bottom is effective on evaluation of balance function, In particular, the test of standing on the platform with the eyes closed effectively reflects the vestibulospinal reflex.
探讨使用带有倾角计和全底面平台的姿势描记法，使受试者在评估身体平衡功能时几乎在一点与地面接触的效果。
使用作者研制的新型带有倾角计和全底面平台的姿势描记仪，对100名年龄在21至50岁之间的正常受试者（男性50名，女性50名）以及87名年龄在20至60岁之间的因半规管麻痹导致周围性眩晕的患者的身体平衡功能进行测量。测量时，将倾斜传感器固定在受试者腰部，要求他们采取四种姿势：睁眼站立在地面上（测试1）、闭眼站立在地面上（测试2）、睁眼站立在平台上（测试3）、闭眼站立在平台上（测试4）。
正常受试者的测量结果显示，身体摆动角速度的平均值在测试1中为0.57±0.24°/秒，测试2中为0.70±0.18°/秒，测试3中为1.16±0.32°/秒，测试4中为2.67±0.70°/秒。87名患者中有62名（71.26%）在4项测试中的一项或多项出现异常，其值超过正常均值x±2s，其中测试1中有7名异常，测试2中有14名，测试3中有16名，测试4中有56名。眩晕发作两周后，87名患者中有55名通过此项检查显示异常值。
带有倾角计和全底面平台的姿势描记法在平衡功能评估中有效，特别是闭眼站立在平台上的测试能有效反映前庭脊髓反射。
