To develop and test a completely new dynamic visual device for the home treatment of benign paroxysmal positional vertigo (BPPV).
Randomized, controlled, prospective trial.
Tertiary care hospital.
We designed and manufactured a new device (the DizzyFix) to assist in the performance of the particle repositioning manoeuvre (PRM). Fifty healthy volunteers were taught the PRM, half using the new device. At 1 week, we compared the PRM performance between the device and nondevice user groups.
Performance of the PRM as graded on an 11-point scale.
DizzyFix users in phase I scored significantly higher on their PRM performance compared with controls (p = .0001).
The use of this new device enables volunteers to conduct a correct PRM on their own. This is a significant improvement from written instructions or in-office training.
研发并测试一种全新的用于家庭治疗良性阵发性位置性眩晕（BPPV）的动态视觉设备。
随机、对照、前瞻性试验。
三级护理医院。
我们设计并制造了一种新设备（DizzyFix），以协助进行颗粒复位手法（PRM）。50名健康志愿者学习了PRM，其中一半使用新设备。在1周时，我们比较了使用设备组和未使用设备组之间的PRM操作情况。
PRM操作情况，采用11分制评分。
第一阶段中，使用DizzyFix的用户在PRM操作表现上得分显著高于对照组（p = 0.0001）。
使用这种新设备能使志愿者自行正确进行PRM。与书面说明或门诊培训相比，这是一项显著的进步。
