Exploring the frontiers of vestibular migraine: A case series.

Introduction: Patients with episodic vestibular syndrome (EVS) whose symptoms resemble those of vestibular migraine (VM) but who do not meet the criteria for it are common.

Objective: To describe those patients suffering from EVS in whom defined etiologies have been ruled out in order to determine if their symptoms can be linked to VM.

Material And Methods: Prospective multicenter study.

Subjective benign paroxysmal positional vertigo in patients with osteoporosis or migraine.

Introduction: Subjective benign paroxysmal positional vertigo is a form of benign paroxysmal positional vertigo in which during the diagnostic positional maneuvers patients only present vertigo symptoms with no nystagmus.

Objective: To study the characteristics of subjects with subjective benign paroxysmal positional vertigo.

Normative data for static balance testing in healthy individuals using open source computerized posturography.

Purpose: Computerized posturography is the gold standard for balance assessment. Because of the great cost and dimensions of commercial equipments, low-cost and portable devices have been developed and validated, such as RombergLab, a software in open source term which works connected with a low-cost force platform. The objective of this study was to obtain normative posturography data using this software.
