Benign paroxysmal positional vertigo clinical, oculographic and postural features

Benign paroxysmal positional vertigo [BPPV] is the most common cause of vertigo of peripheral origin. Clinical, oclulographic and postural features in 212 patients with BPPV were reported. For all participants, history taking, Frenzel glass visualization of nystagmus, electronystagmograph [ENC] and sensory organization test [SOT] were performed. Females outnumbered males. The peak of incidence occurs in the six decade of age. The majority of cases belong to the idiopathic group. Abnormaities in calric testing were found in 42% of participants. Only 2 patients had central ENG results. SOT quantifies the patient's ability to maintain balance when visual and/or somatosensory cues are either absent or inappropriate

Efficacy of Epley maneuver for treatment of posterior canal benign paroxysmal positional vertigo

Presently, the treatment of choice for benign paroxysmal positional vertigo [BPPV] resulting from posterior canalithiasis [PC-BPPV] is the Epley maneuver. The aim of this work was t evaluate the short and long-term results of the Epley canalith maneuver as a treatment modality for PC-BPPV. Sixty-two patients with acute untreated PC-BPPV were recruited. They were divided into two groups. The first group [n=31] were treated by Epley maneuver. The second [n=31] received placebo treatment in the form of sugar capsules. For 32 subjects with posture and gait complaint, sensory organization test [SOT] was performed. All were followed up for one year. The results indicated that the Epley maneuver recovery rate was 87%. Three cases had deterioration of symptoms [one converted to later canal and two to anterior canal BPPV]. Out of the 31 patients [group, 2] 13 had spontaneous recovery and four remained symptomatic till the end of the year follow up. Regarding SOT results, out of the 25 participants with initial positive results, 15 [60%] had total improvement. On the other hand, four and six patients had partial and on improvement respectively and they required a further appropriate vestibular rehabilitation program
