To better understand VS mechanisms and characteristics in humans, we analyzed retrospectively functional measures of gait, electrophysiological measures of vestibular function,\n and imaging studies in an attempt to determine clinical, electrophysiological, and anatomical correlates of abnormalities in VS.Two cohorts of patients referred to our Risk of Falls Assessment Clinic participated in this investigation. Group 1 (control) patients demonstrated normal caloric\n and rotary chair tests. Group 2 patients with impaired velocity storage (experimentals) differed clinically from Group 1 only by demonstrating abnormal multifrequency vestibulocular reflex phase measures on rotational testing.Results showed that Group 2 patients had greater impairments in\n postural stability and gait than Group 1 patients. Additionally, 80% of patients in Group 2 and none in Group 1 showed pontine hyperintense lesions on MRI.

Para entender mejor los mecanismos y caracter\u00edsticas de la VS en humanos, analizamos retrospectivamente medidas funcionales de la marcha, medidas electrofisiol\u00f3gicas de funci\u00f3n vestibular, y estudios de im\u00e1genes, en un intento de determinar correlaciones\n cl\u00ednicas, electrofisiol\u00f3gicas y anat\u00f3micas en las anormalidades de la VS.Dos cohortes de pacientes referidos a nuestra Cl\u00ednica de Evaluaci\u00f3n de Riesgo de Ca\u00eddas participaron en esta investigaci\u00f3n. Los pacientes del Grupo 1 (control) demostraron\n normalidad en las pruebas cal\u00f3ricas y de silla rotatoria. Los pacientes del Grupo 2 con velocidad de almacenamiento alterada (experimentales) fueron diferentes de aquellos del Grupo 1 s\u00f3lo por demostrar medidas anormales en la fase de reflejo vest\u00edbulo-ocular multifrecuencial,\n en pruebas de rotaci\u00f3n.Los resultados mostraron que los pacientes del Grupo 2 ten\u00edan mayor alteraci\u00f3n en la estabilidad postural y la marcha, que los pacientes del Grupo 1.
