We evaluated a new therapeutic maneuver-Prolonged Position on the healthy side, for Benign Paroxysmal Positional Vertigo (BPPV) of the horizontal semicircular canal. We devised this type of physical treatment in accordance with the "canalolithiasis" theory of BPPV, in order to try to free the horizontal semicircular canal of otoconial debris. We compared the results obtained by Prolonged Position with two other physical therapies by dividing our horizontal canal BPPV patients into three therapeutic groups: 1) 35 patients treated with Prolonged Position; 2) 24 patients treated with head shaking in a supine position; 3) 15 patients for whom therapy was omitted. More than 90% of the patients treated with Prolonged Position recovered within 3 days, although 6 patients out of 35 subsequently developed BPPV of the posterior semicircular canal, which then responded well to a particular repositioning maneuver. The results of Prolonged Position were significantly better than those obtained by performing head shaking or by omitting treatment. Prolonged Position can be applied to patients of all ages and general conditions and does not require hospitalization.
我们评估了一种针对水平半规管良性阵发性位置性眩晕（BPPV）的新治疗手法——健侧卧位延长法。我们依据BPPV的“管结石症”理论设计了这种物理治疗方法，试图清除水平半规管内的耳石碎片。我们将水平半规管BPPV患者分为三个治疗组，比较了健侧卧位延长法与另外两种物理疗法的治疗效果：1）35例采用健侧卧位延长法治疗的患者；2）24例采用仰卧位摇头治疗的患者；3）15例未接受治疗的患者。采用健侧卧位延长法治疗的患者中，超过90%在3天内康复，尽管35例中有6例随后出现后半规管BPPV，但对特定的复位手法反应良好。健侧卧位延长法的治疗效果明显优于仰卧位摇头治疗或不治疗。健侧卧位延长法适用于所有年龄和一般状况的患者，且无需住院治疗。
