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.
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。
