针对第一种可能,Roll试验表现为双侧定向性水平眼震的LC-BPPV实质上是单侧前臂型管石症,在变位试验开始时我们应首先注意观察患者低头-仰头试验(bow and lean test)或坐位-仰卧位试验(lying down test)眼震。文献报道,约有76%的LC-BPPV...
水平半规管BPPV 诊断 ➤ 水平半规管管耳石:Roll test检查诱发水平向地性眼震(可略带扭转成分),持续时间<1 min,则可判定为漂浮于外半规管后臂内的管石症。 ➤ 水平半规管嵴帽耳石:Roll test检查诱发水平离地性眼震,持续时间≥1 min,且与...
A positive Supine-Roll test consists of a burst of horizontal nystagmus (jumping of the eyes). In lateral canal BPPV, the eyes jump sideways, to opposite directions depending on the side that is down (this is called "direction changing"). As the eyes can either always jump down, or up ...

and alternative positional tests, such as head-shaking test (HST), seated supine positioning test (SSPT), bow and lean test (BLT), and rapid axial roll test (RART) in determining the affected semicircular canal of horizontal semicircular canal benign paroxysmal positional verti...
the efficiency of the supine roll test (SRT) and alternative positional tests (APTs) including the bow and lean test (BLT), pseudo-spontaneous nystagmus (PSN), and lying down nystagmus (LDN) to identify the affected side in horizontal canal benign paroxysmal positional vertigo (HC-BPPV). ...
For whatever reason, the simple procedure of repeating the DH maneuver after the horizontal maneuver has increased positivity.12 In this study, we aimed to investigate the diagnostic value of repeated Dix-Hallpike and Roll maneuvers in BPPV. Methods We prospectively evaluated 207 patients (52.67 ±...
The influence of additional roll test on the repositioning procedure by SRM-vertigo diagnosis system for horizontal canal benign paroxysmal positional vertigo. Journal of Clinical Otorhinolaryngology Head and Neck Surgery, 2023, 37(4): 268-268. doi: 10.13201/j.issn.2096-7993.2023.04.006 [2] ZHANG...
(BPPV) is characteristically brief, transient and adapts to repeated tests. Presence of bi-directional, horizontal positional nystagmus (geotropic or apogeotropic) during head-roll maneuver indicates lateral canal benign paroxysmal positional vertigo (BPPV). Affected side is confirmed with respect to the...
Objectives: The purpose of this systematic review was to determine which current roll and side-lying maneuvers are most effective while treating individuals with geotropic horizontal canal BPPV. Methods: CINAHL Complete, PubMed, and Web of Science were the databases accessed from inception through ...
