Abstract
Objective To verify the objectivity and reproducibility of a portable video nystagmus visualization device for dizziness screening in primary healthcare settings.Methods A total of 40 participants were enrolled from January 2024 to December 2025 at the Children's Hospital Affiliated to Soochow University and Suzhou Wuzhong People's Hospital,including a vertigo group(n=20 including 8 children,9 males and 11 females,mean age=46.35±10.24 years)and a healthy control group(n=20 including 5 children,10 males and 10 females,mean age=44.80±11.15 years).The two groups were matched in age and gender(t=1.57,P=0.123;χ²=2.88,P=0.087).Nystagmus was simultaneously recorded During the Dix-Hallpike and roll tests using the portable video nystagmus visualization device,smartphone video,and direct visual observation.All video recordings were independently reviewed by two blinded senior clinicians to assess the presence,dominant direction and duration of nystagmus.Results The portable device successfully captured nystagmus videos from both groups without significant motion artifacts,including nystagmus in BPPV involving the posterior canal in 10 cases,multi-canal involvement in 4 cases,and horizontal canal in 4 cases,and provided objective evidence of nystagmus in 2 suspected cases.The nystagmus direction identified by expert interpretation using the device agreed with clinical diagnosis in 38 cases(95%,Kappa=0.90),indicating excellent consistency.This was significantly superior to smartphone recording(82.5%,Kappa=0.65)and naked-eye observation(77.5%,Kappa=0.55).Conclusions The portable video nystagmus visualization device is user-friendly and cost-effective.It effectively improves the objectivity and accuracy of nystagmus observation and is particularly suitable for dizziness screening in primary care settings and in pediatric populations.关键词
