randomized clinical trial for geotropic horizontal canal benign paroxysmal positional vertigo
Neurology, 2012Co-Authors: Sunyoung Oh, Jihoon Kang, Seonghae Jeong, Kwangdong Choi, I S MoonAbstract:OBJECTIVES: To determine the immediate and long-term therapeutic efficacies of barbecue rotation and Gufoni Maneuvers, a randomized, prospective, and sham-controlled study was conducted in patients with the geotropic type of benign paroxysmal positional vertigo involving the horizontal semicircular canal (HC-BPPV). METHODS: In 10 nationwide dizziness clinics in Korea, 170 consecutive patients (107 women, age range 11-97 years, mean age ± SD 61 ± 15 years, median = 61 years) with geotropic HC-BPPV were randomly assigned to barbecue rotation (n = 56), Gufoni (n = 64), or sham maneuver (n = 50). An immediate response was determined within 1 hour after a maximum of 2 trials of each maneuver on the visit day. We also assessed the cumulative results of each maneuver by following up the patients for 1 month. RESULTS: After a maximum of 2 Maneuvers on the initial visit day, barbecue rotation (38 of 55 [69.1%]) and Gufoni (39 of 64 [60.9%]) Maneuvers showed better responses than the sham maneuver (17 of 48 [35.4%]). The cumulative therapeutic effects were also better with barbecue rotation (p = 0.006) and Gufoni (p = 0.031) Maneuvers than with the sham maneuver. However, therapeutic efficacies did not differ between the barbecue rotation and Gufoni groups in terms of both immediate (p = 0.46) and long-term (p = 0.10) outcomes. CONCLUSION: Using a prospective randomized trial, we demonstrated that barbecue rotation and Gufoni Maneuvers are effective in treating geotropic HC-BPPV. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that barbecue rotation and Gufoni Maneuvers are effective in the treatment of geotropic HC-BPPV.

randomized clinical trial for apogeotropic horizontal canal benign paroxysmal positional vertigo
Neurology, 2012Co-Authors: Sunyoung Oh, I S Moon, Jihoon Kang, Sookhyang Jeong, Kyungun Choi, H J OhAbstract:Objective: To determine the immediate and long-term therapeutic efficacies of Gufoni and head-shaking Maneuvers in apogeotropic type of benign paroxysmal positional vertigo involving the horizontal semicircular canal (HC-BPPV), a randomized, prospective, sham-controlled study was conducted. Methods: In 10 nationwide dizziness clinics in Korea, 157 consecutive patients (95 women, age range: 18–89 years, mean age ± SD = 59.9 ± 13.6) with apogeotropic HC-BPPV were randomized to Gufoni (n = 52), head-shaking (n = 54), or sham maneuver (n = 51). For Gufoni maneuver, patients underwent ipsilesional side-lying and upward head-turn for migration of the debris toward the vestibule. Immediate responses were determined within 1 hour after a maximum of 2 trials of each maneuver and in the following day. The patients also had weekly follow-ups for 1 month after the initial maneuver. Results: After a maximum of 2 Maneuvers on the initial visit day, Gufoni (38/52, 73.1%) and head-shaking (33/53, 62.3%) Maneuvers showed better responses than the sham maneuver (17/49, 34.7%). The cumulative therapeutic effects were also better with Gufoni ( p p = 0.026) Maneuvers compared with the sham maneuver. However, therapeutic efficacies did not differ between the Gufoni and head-shaking groups in terms of both immediate ( p = 0.129) and long-term ( p = 0.239) outcomes. Conclusion: Using a prospective randomized trial, we demonstrated that the Gufoni and head-shaking Maneuvers are effective in treating apogeotropic HC-BPPV. Classification of evidence: This study provides Class II evidence that Gufoni and head-shaking Maneuvers are effective in treating apogeotropic horizontal BPPV up to 1 month after initial treatment. Clinical trial registration: NCT00810641.

Treatment of apogeotropic benign positional vertigo: comparison of therapeutic head-shaking and modified Semont maneuver
Journal of Neurology, 2009Co-Authors: S.y. Oh, S.-h. Jeong, Y.-m. Oh, K. D. Choi, I S MoonAbstract:Several methods of physiotherapy have been advanced for apogeotropic type benign positional vertigo involving the horizontal semicircular canal (HC-BPV). The aim of this study was to determine the therapeutic efficacies of the proposed Maneuvers in apogeotropic HC-BPV. Using a prospective randomized trial involving seven nationwide dizziness clinics in Korea, we compared the immediate efficacies of head-shaking and modified Semont Maneuvers in 103 consecutive patients with apogeotropic HC-BPV. We also determined an additional therapeutic benefit of mastoid oscillation while the patients without response to both Maneuvers were performing the Brandt–Daroff exercise. Successful treatment was defined as resolution of positional vertigo and nystagmus, or as transition into geotropic HC-BPV. Results showed that head shaking was more effective than the modified Semont maneuver (37.3 vs. 17.3%, P = 0.02). However, therapeutic efficacy did not differ between the Maneuvers after the initial non-responders switched over to the other maneuver (23.3 vs. 25.0%, P = 0.861). Mastoid oscillation provided no additional benefit while the patients without response to both Maneuvers were performing the Brandt–Daroff exercise. Most positional vertigos resolved within a week (89.4%) irrespective of the treatment modalities applied and all showed resolution within 28 days. The head-shaking maneuver described here proved more effective than the modified Semont maneuver in treating apogeotropic HC-BPV. Mastoid vibration conferred no additional benefit during the Brandt–Daroff exercise.

Real-time motion planning with a fixed-wing UAV using an agile maneuver space
Autonomous Robots, 2019Co-Authors: Joshua M. Levin, Meyer Nahon, Aditya A. ParanjapeAbstract:Small fixed-wing unmanned aerial vehicles (UAVs) are becoming increasingly capable of flying at low altitudes and in constrained environments. This paper addresses the problem of automating the flight of a fixed-wing UAV through highly constrained environments. The main contribution of this paper is the development of a maneuver space, integrating steady and transient agile Maneuvers for a class of fixed-wing aircraft. The maneuver space is integrated into the rapidly-exploring random trees (RRT) algorithm. The RRT-based motion planner, together with a flight control system, is demonstrated in simulations and flight tests to efficiently generate and execute a motion plan through highly constrained 3D environments in real-time. The flight experiments—which effectively demonstrated the usage of three highly agile Maneuvers—were conducted using only on-board sensing and computing.

success of the modified epley maneuver in treating benign paroxysmal positional vertigo
Laryngoscope, 1999Co-Authors: Jeffrey S. Wolf, Kestutis P Boyev, Brenda J Manokey, Douglas E MattoxAbstract:Objective: Benign paroxysmal positional vertigo (BPFV) is a common condition seen by otolaryngologists. The purpose of this study is to determine the ability of the modified Epley maneuver to treat BPPV. Study Design: Retrospective review. Methods: A retrospective chart review of 107 patients diagnosed with BPPV at our institution between March of 1993 and June of 1995. Each patient was diagnosed with isolated BPPV by history and Hallpike-Dix maneuver. There were no other vestibular symptoms or electronystagmogram abnormalities. Patients diagnosed with BPPV received modified Epley Maneuvers, were instructed to remain upright for 48 hours, and wore a soft collar for a week. Patients were followed up with repeat Hallpike-Dix Maneuvers at 1 to 2 weeks. If symptoms persisted, the maneuver was repeated for up to a maximum of three times, at which point patients were considered to have failed treatment. Results: The average age of patients was 57.8 years old. Thirty percent were male and the right ear was affected in 54%. The posterior semicircular canal was affected in 105 ears. The average patient received 1.23 Epley Maneuvers, with a success rate of 93.4%. No successfully treated patients received mastoid vibration. Seven out of 107 patients failed after three Epley Maneuvers. Two failure patients had a history of temporal bone fracture. Two failure patients were treated with posterior semicircular canal block surgery. Conclusion: The modified Epley maneuver is an excellent treatment for BPPV. Key Words: Vertigo, benign paroxysmal positional vertigo (BPPV), Epley maneuver, semicircular canal.
