Study Design: Prospective study of 35 cases of BPPV. Materials and Method: 35 patients of BPPV presenting at vertigo clinic of ENT department at Civil Hospital Ahmedabad were treated with canalolith repositioning procedure and improvement in nystagmus was studied and confirmed by VNG. Observation: 31 patients out of 35 patients were improved with 1st CRP, 2 out of 3 patients improved with 2nd CRP and 1 patient improved with 3rd CRP. This improvement is confirmed using VNG. Conclusion: Videonystagmography is a very useful tool for ensuring the otolith repositioning by the canalith repositioning manouver. It is a confirmatory adjunct to visual analysis.展开更多

Although the canalith repositioning maneuver (CRM) is the standard of care, the most effective method to deliver it in the ED hasbeen poorly studied.Objective: To compare two protocols of the Epley maneuver for the treatment of PC-BPPV.Patients and methods: We prospectively recruited 101 patients with unilateral PC-BPPV on physical examination, randomizing them to either a single Epley maneuver (EM) (n ¼ 46) or multiple maneuvers(n ¼ 55) on the same visit. Measured outcomes included presence/absence of positional nystagmus,resolution of vertigo, and score on the dizziness handicap inventory (DHI) at follow-up evaluations. TheDHI was stratified into mild ( 30) and moderate-severe (>30).Results: Normalization of the Dix-Hallpike maneuver at day 5 was observed in 38% of the single EMgroup and 44.4% in the multiple EM group (p ¼ 0.62). The DHI showed reduction from 42.2 (SD 18.4) to31.9 (SD 23.7) in the single EM group and from 43.7 (SD 22.9) to 33.5 (SD 21.5) in the multiple EM group(p ¼ 0.06). A higher number of patients improved from moderate-severe to mild DHI (p ¼ 0.03) in thesingle EM group compared to the multi-EM group (p ¼ 0.23).Conclusion: There was no statistically significant difference between performing a single EM versusmultiple EMs for treatment of PC-BPPV in the emergency department. The single EM approach isassociated with shorter physical contact between patients and examiner, which is logically safer in apandemic context.展开更多

Firstly, ...This paper is mainly concerned with the coupling dynamic analysis of a complex spacecraft consisting of one main rigid platform, multiple liquid-filled cylindrical tanks, and a number of flexible appendages. Firstly, the carrier potential function equations of liquid in the tanks are deduced according to the wall boundary conditions. Through employ- ing the Fourier-Bessel series expansion method, the dynamic boundaries conditions on a curved free-surface under a low-gravity environment are transformed to general simple differential equations and the rigid-liquid coupled sloshing dynamic state equations of liquid in tanks are obtained. The state vectors of rigid-liquid coupled equations are composed with the modal coordinates of the relative potential func- tion and the modal coordinates of wave height. Based on the B ernoulli-Euler beam theory and the D＇Alembert＇s prin- ciple, the rigid-flexible coupled dynamic state equations of flexible appendages are directly derived, and the coordi- nate transform matrixes of maneuvering flexible appendages are precisely computed as time-varying. Then, the cou- pling dynamics state equations of the overall system of the spacecraft are modularly built by means of the Lagrange＇s equations in terms of quasi-coordinates. Lastly, the cou-piing dynamic performances of a typical complex spacecraft are studied. The availability and reliability of the presented method are also confirmed.展开更多
