Summary

This study is designed to examine the true impact inner-ear dysfunction has on patient head movement kinematics, activity levels, and participation, and (2) to explore the efficacy of rehabilitation on laboratory, clinical, and community-based outcomes in people following surgical removal of a schwannoma from the inner-ear nerve.

Description

In this project we will focus on characterizing deficits in community-based performance (i.e., head and trunk control during simulated community activities, short term community mobility, and patient reported participation) and relating these deficits to laboratory (i.e., video head impulse testing and corrective postural responses) and clinical (i.e., MiniBEST and dynamic visual acuity, and visual spatial cognition) measures of gaze and postural stability in individuals with varied forms of vestibulopathy (unilateral vestibular neuritis, bilateral vestibular loss, migraine related vestibulopathy, concussion, BPPV, Multiple Sclerosis). Additionally, we will examine the longitudinal change of laboratory, and community-based measures of gaze and postural in two cohorts of people with a specific form of unilateral vestibular loss (Vestibular Schwannoma resection); one group of these individuals will receive 6 weeks of vestibular rehabilitation during the acute onset of symptoms and the other one will begin intervention 6 weeks post onset. This portion of the proposed project will test my global hypothesis that changes in community-based performance of head and trunk control impair recovery following the onset of VH.

Aim 1: In individuals with vestibulopathy, characterize and compare laboratory and clinical measures of body structure, function, and performance to community-based, activity levels, performance, and patient reported participation. Hypothesis 1: The severity of laboratory and clinically measured gaze and postural stability function deficits will not strongly correlate with head and trunk control during community-based performance or patient reported participation. Hypothesis 2: The nature and severity of laboratory and clinically measured gaze and postural stability function deficits will differ between varied diagnostic groups.

Aim 2: In individuals with unilateral vestibular hypofunction following unilateral vestibular schwannoma resection, examine the longitudinal trajectories of laboratory and clinical measures of body structure, function and performance, and community-based performance, activity levels, and patient reported participation during periods of spontaneous and rehabilitation driven recovery. Hypothesis: Recovery of laboratory and clinical measures will follow different trajectories than measures of community-based performance and patient reported participation during both periods of spontaneous and rehabilitation driven recovery.
