Dozza M，基亚里L，Horak FB.听觉生物反馈改善双侧前庭功能丧失患者的平衡。Arch Phys Med Rehabil 2005;86：1401- 3.目的：评价听觉生物反馈（ABF）系统改善双侧前庭丧失（BVL）患者平衡的有效性。设计：前后试验。设置：大学平衡障碍实验室。参与者：9名BVL受试者和9名未受影响的受试者作为对照。干预：闭着眼睛站在泡沫上时躯干加速ABF。主要结果测量：根据以下参数评估平衡稳定性：（1）压力中心（COP）位移和（2）躯干加速度的均方根; COP带宽;参与者在基线COP位置+/- 1度阈值内所花费的时间;和躯干的平均加速度，而参与者是摇摆以外的1度thresholds.Results：参与者与BVL有显着更大的姿势摇摆比未受影响的参与者。BVL患者在使用ABF时，摇摆面积减少了23% +/-4.9%，躯干加速度减少了46% +/-9.9%，在+/- 1度摇摆阈值内花费的时间增加了195% +/-34.6%。结论：ABF通过增加姿势矫正量来改善BVL患者的站立稳定性。(c)2005年由美国康复医学大会和美国物理医学与康复学院。
Dozza M, Chiari L, Horak FB. Audio-biofeedback improves balance in patients with bilateral vestibular loss. Arch Phys Med Rehabil 2005;86:1401-3.Objective: To evaluate the effectiveness of an audio-biofeedback (ABF) system for improving balance in patients with bilateral vestibular loss (BVL).Design: Before-after trial.Setting: University balance disorders laboratory.Participants: Nine subjects with BVL and 9 unaffected subjects as controls.Intervention: Trunk acceleration ABF while standing on foam with eyes closed.Main Outcome Measure: Balance stability was evaluated according to the following parameters: the root mean square of (1) the center of pressure (COP) displacements and of (2) the trunk accelerations; the COP bandwidth; the time spent by the participant within +/- 1 degrees threshold from their baseline COP position; and the mean accelerations of the trunk while the participant was swaying outside this 1 degrees threshold.Results: Participants with BVL had significantly larger postural sway than did unaffected participants. Those with BVL, while using ABF, decreased sway area by 23% +/- 4.9%, decreased trunk accelerations by 46% +/- 9.9%, and increased time spent within +/- 1 degrees sway threshold by 195% +/- 34.6%.Conclusions: ABF improved stance stability of participants with BVL by increasing the amount of postural corrections.
