Particle repositioning, using either bedside techniques or whole-body manipulation devices, has been used effectively to treat benign positional vertigo (BPV). We assessed the efficacy of particle repositioning using a device designed and built specifically to treat BPV that rotated patients 360 degrees heels-over-head in their sagittal body plane while their heads were turned to align the posterior semicircular canal with the plane of rotation. Eye movements were monitored during the maneuver by an infrared video recording system that allowed subsequent review of the induced nystagmus. Our results indicate that 1) heels-over-head rotation is an extremely efficacious procedure for treating patients with BPV and 2) the pattern of nystagmus during repositioning is consistent with the theory that free-floating debris is highly likely to account for BPV.
使用床边技术或全身操纵设备进行颗粒复位，已被有效用于治疗良性阵发性位置性眩晕（BPV）。我们评估了一种专门设计和制造用于治疗BPV的设备进行颗粒复位的疗效，该设备可使患者在矢状身体平面内头朝下旋转360度，同时头部转动以使后半规管与旋转平面对齐。在操作过程中，通过红外视频记录系统监测眼球运动，以便后续查看诱发的眼球震颤。我们的结果表明：1）头朝下旋转是治疗BPV患者的一种极其有效的方法；2）复位过程中眼球震颤的模式与以下理论一致，即自由漂浮的碎片很可能是BPV的病因。
