Abstract：
Mobility limitation of the cervical spine compromises the adequate execution of the canalith repositioning maneuver (CRM) in cases of posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV-GEO). Thus, novel therapeutic options are required for such individuals.
This study describes the effects of a change in the biomechanical position for the execution of the CRM on symptoms of dizziness and mobility limitation regarding flexion-extension of the cervical spine in older people with unilateral PSC-BPPV-GEO.
A quasi-experimental viability study was conducted with 15 older adults (11 women; mean age: 72.2 ± 8.1 years). Treatment consisted of a hybrid CRM. The participants were evaluated before and after the intervention using the modified Dix & Hallpike test, Dizziness Handicap Inventory (DHI) and a visual analog scale (VAS) for vertigo.
The modified Dix & Hallpike test was negative in all cases after the execution of the hybrid CRM. A significant reduction was found for dizziness measured using the DHI (mean difference: -39.3 ± 9.4, p < 0.001) and VAS (mean difference: -2.9 ± 0.8, p = 0.04) after the intervention.
The hybrid CRM proved executable and satisfactory for resolving symptoms of dizziness in older adults with PSC-BPPV. The present findings are promising and randomized controlled clinical trials should be conducted to evaluate the effectiveness of the hybrid CRM in this population.

摘要：
背景：在后半规管良性阵发性位置性眩晕（PSC-BPPV-GEO）的情况下，颈椎的活动限制会损害耳石复位动作（CRM）的适当执行。因此，这些个体需要新的治疗选择。
目的：本研究描述了执行CRM的生物力学位置变化对单侧PSC-BPPV-GEO老年人颈椎屈伸性头晕和活动受限症状的影响。
方法：对15名老年人（11名女性；平均年龄：72.2±8.1岁）进行了一项准实验性生存能力研究。治疗包括混合CRM。参与者在干预前后使用改良的Dix&Hallpike测试进行评估，眩晕障碍量表(DHI)和眩晕视觉模拟量表(VAS)。
结果：在执行混合CRM后的所有情况下，改良的Dix＆Hallpike测试均为阴性。在干预后，使用DHI（平均差：-39.3±9.4，p<0.001）和VAS（平均差：-2.9±0.8，p=0.04）测量的头晕显着降低。
结论：混合CRM被证明可用于解决患有PSC-BPPV的老年人的头晕症状，并且令人满意。目前的发现是有希望的，应该进行随机对照临床试验来评估混合CRM在该人群中的有效性。
