作者对11例外周性前庭损害、17例中枢性前庭损害患者及20例正常人观察了在休息状态及在振动刺激腓肠肌和颈肌本体感受器后的直立姿态下身体晃动情况,体位的稳定性用姿态平均偏斜(ADBP)来评定。实验中,受试者垂直站立,膝关节靠拢,双臂交叉于胸前,脚跟并拢,脚尖分开30°。将振动器川弹性带紧附于双腿腓肠肌,并用一个固定领圈将两个振动器分别固定于双侧第七颈椎水平旁正中位表面的肌肉上。振动频率分别为32、62、100、125和150Hz,波形为正弦曲线,振幅为2.1mm。用以应变原理为基础的压力平台(Bofors,BKF-1-C,Sweden)来测定前后方向压力中心点(CPF)的变化,并将这些变化描记下来。试验前先测定受试者在尽量前倾和后仰而
In 11 cases of peripheral vestibular damage, 17 cases of central vestibular damage and 20 cases of normal subjects were observed at rest and in vibration-induced gastrocnemius and neck muscle proprioceptor posture after the body’s shaking, posture stability Attitude mean skew (ADBP) to assess. In the experiment, the subjects stood vertically with their knees moving closer, arms crossed over their chests, their heels closed and their toes separated by 30 °. The vibrator Chuan elastic belt tightly attached to the gastrocnemius of the legs, and a fixed collar will be two vibrators were fixed to the bilateral mid-seventh cervical horizontal median muscle. The vibration frequencies were 32, 62, 100, 125 and 150 Hz, respectively. The waveform was sinusoidal with an amplitude of 2.1 mm. The changes of the pressure center point (CPF) in the anteroposterior direction and in the posterior direction were measured using a strain gauge based pressure platform (Bofors, BKF-1-C, Sweden) and these changes were recorded. Subjects were determined to lean forward and backwards before testing
