The evolution of patient-reported outcome measures after a first lateral ankle sprain: A prospective study.

Purpose: A lateral ankle sprain is the most common musculoskeletal injury in the physically active population. However, it is unclear how the clinical condition evolves during the period after the injury and what proportion of patients develops chronic symptoms. Therefore, the purpose of this study is to assess the evolution of patient-reported outcome measures after a first time lateral ankle sprain.

A Novel Saccadic Strategy Revealed by Suppression Head Impulse Testing of Patients with Bilateral Vestibular Loss.

Objective: We examined the eye movement response patterns of a group of patients with bilateral vestibular loss (BVL) during suppression head impulse testing. Some showed a new saccadic strategy that may have potential for explaining how patients use saccades to recover from vestibular loss.

Methods: Eight patients with severe BVL [vestibulo-ocular reflex (VOR) gains less than 0.

Sustained and Transient Vestibular Systems: A Physiological Basis for Interpreting Vestibular Function.

Otolithic afferents with regular resting discharge respond to gravity or low-frequency linear accelerations, and we term these the static or sustained otolithic system. However, in the otolithic sense organs, there is anatomical differentiation across the maculae and corresponding physiological differentiation. A specialized band of receptors called the striola consists of mainly type I receptors whose hair bundles are weakly tethered to the overlying otolithic membrane.

Balance in Virtual Reality: Effect of Age and Bilateral Vestibular Loss.

Background: Quantitative balance measurement is used in clinical practice to prevent falls. The conditions of the test were limited to eyes open, eyes closed, and sway-referenced vision. We developed a new visual perturbation to challenge balance using virtual reality (VR), measuring postural stability by a Wii Balance Board (WBB).

An Attempt of Early Detection of Poor Outcome after Whiplash.

The main concern with whiplash is that a large proportion of whiplash patients experience disabling symptoms or whiplash-associated disorders (WAD) for months if not years following the accident. Therefore, identifying early prognostic factors of WAD development is important as WAD have widespread clinical and economic consequences. In order to tackle that question, our study was specifically aimed at combining several methods of investigation in the same WAD patients at the acute stage and 6 months later.
