METHODS: Twenty-two patients with BPPV (negative DixHallpike/Roll test results, existing dizziness/balance complaints) were randomly allocated to the study group (SG, n:11 3D-VRT) or Control group (CG n:11, no exercise-rehabilitation) for 8 week. The SG performed 3D-VRT for 45 to 50 min/d, 3 times/wk, and the CG did receive only Canalith Repositioning Maneuver (CRM). CRM was applied in both groups before the study. Outcome measures included 10-Meter-Walk-Test (10-MWT) (with/without head turns), Dynamic Gait Index (DGI), Choice-Stepping-Reaction-Time-ped (CSRT-MAT), Fullerton Advanced Balance Scale (FAB), and Visual Analog Scale (VAS).
RESULTS: The SG showed significantly improvement in 10-MWT without (p5 = 0.00,η2 = 0.49), with horizontal (p5 = 0.00,η2 = 0.57),vertical (p5 = 0.01,η2 = 0.48) head turns, DGI (p5 = 0.00,η2 = 0.74), CSRT-MAT, FAB (p5 = 0.00,η2 = 0.78) and VAS-dizziness (p5 = 0.00,η2 = 0.65), VAS-balance problem (p5 = 0.00,η2 = 0.43), VAS-fear of falling (p5 = 0.00,η2 = 0.42) compared to the CG.
CONCLUSIONS: The 3D-VRT were effective in improving gait, balance, processing speed and resolving the subjective complaints in BPPV. The 3D-VRT method is feasible for patients who suffer from residual dizziness or balance complaints after CRM. Furthermore, the 3D-VRT is more accessible and less expensive than other virtual reality applications, which may facilitate further research or clinical use.
方法:22例BPPV患者(DixHallpike/Roll试验结果阴性,现有的头晕/平衡投诉)随机分配到研究组(SG,n:113D-VRT)或对照组(CGn:11,无运动康复),为期8周。SG执行3D-VRT45至50分钟/天,3次/周,CG确实只收到了Canalith重新定位机动(CRM)。研究前两组均采用CRM。结果测量包括10米步行测试(10-MWT)(有/没有头转弯),动态步态指数(DGI)选择步进反应时间(CSRT-MAT),富勒顿高级平衡秤(FAB),和视觉模拟量表(VAS)。
结果:SG在没有(p5=0.00,η2=0.49)的情况下显示出10-MWT的显着改善,水平(p5=0.00,η2=0.57),垂直(p5=0.01,η2=0.48)头转弯,DGI(p5=0.00,η2=0.74),CSRT-MAT,FAB(p5=0.00,η2=0.78)和VAS-头晕(p5=0.00,η2=0.65),VAS平衡问题(p5=0.00,η2=0.43),VAS-与CG相比对跌倒的恐惧(p5=0.00,η2=0.42)。
结论:3D-VRT可有效改善步态,balance,处理速度和解决BPPV中的主观投诉。3D-VRT方法对于CRM后残留头晕或平衡不适的患者是可行的。此外,3D-VRT比其他虚拟现实应用程序更易于访问且更便宜,这可能有助于进一步的研究或临床使用。
