A hydraulically driven, digitally servo-controlled multi-axes rotary chair is described. This device generates motion profiles with the subjects head in the center of rotation mainly in order to adequately stimulate the semicircular canals which are sensitive sensors for angular accelerations. This newly developed apparatus allows for motion stimuli which are below the vestibular threshold up to accelerations of 12 rad/s2 (688 degrees/s2) and is thus suitable for a variety of experiments in the field of vestibular, oculomotor, and intersensory research in 3-dimensional space.

Time to Rehabilitation in Pediatric Concussion Patients Influences Recovery Outcomes.
J Sport Rehabil
December 2024
Children's Health Andrews Institute, Plano, TX, USA.
Context: Targeted and directed rehabilitation with a healthcare provider can be an effective approach in the treatment of concussion, particularly for patients with protracted recovery, high symptom reporting, cervicogenic dysfunction, musculoskeletal involvement, and/or vestibular/oculomotor dysfunction. While many environmental and intrinsic medical history factors may influence concussion recovery, little is known about whether an individual's recovery trajectory can be influenced by the amount of time taken to receive rehabilitation. The purpose of this study was to evaluate recovery trajectories of concussion patients requiring targeted multimodal rehabilitation after a specialty concussion clinic visit within ≤3 days, 4 to 7 days, and >7 days.

Objective: Sport-related concussion (SRC) affects cognitive and oculomotor function. We evaluated recovery from SRC in athletes with cognitive symptoms and/or oculomotor impairments who were prescribed early aerobic exercise treatment.
Design: Secondary exploratory analysis of a randomized controlled trial.

Quantitative Oculomotor and Vestibular Profile in Spinocerebellar Ataxia Type 6 - Systematic Review and Meta-Analysis.
Cerebellum
December 2024
NeuroMetrology Lab, Nuffield Department of Clinical Neurosciences, Clinical Neurology, Medical Sciences Division, University of Oxford, Oxford, OX3 9DU, UK.
Whereas several studies have reported on quantitative oculomotor and vestibular measurements in spinocerebellar ataxia type 6 (SCA6), selecting the most suitable paradigms remains challenging. We aimed to address this knowledge gap through a systematic literature review and providing disease-specific recommendations for a tailored set of eye-movement recordings in SCA6. A literature search (MEDLINE, Embase) was performed focusing on studies reporting on quantitative oculomotor and/or vestibular measurements in SCA6-patients.

Background: Oculomotor and reaction time tests are frequently used assessments of vestibular symptoms, traumatic brain injury (TBI), or other neurological disorders in both clinical and research contexts. When interpreting these tests it is important to have a reference interval (RI) as a comparison for what constitutes a typical/expected response; however, the current body of research has only limited information regarding normative ranges calculated according to established standards or for a military-specific sample.
Purpose: The purpose of the present study was to describe RIs for oculomotor and reaction time tests in a cohort of service members and veterans (SMVs) for use as comparators by clinicians and scientists.
