Comparison of digital recruitment strategies for Alzheimer's disease patients.

Objectives: Clinical trials studying Alzheimer's Disease (AD) face the challenge of recruiting participants with significant barriers to entering research studies. The objective of this study is to compare digital recruitment strategies' ability to recruit older adults with cognitive impairment (CI).

Methods: Older adults with CI were recruited for a clinical trial studying vestibular therapy in reducing falls and improving balance and cognition in older adults with CI.

Local spatial navigation or "steering" in patients with vestibular loss in a virtual reality environment.

Background: Patients with vestibular loss have reduced wayfinding ability, but the association between vestibular loss and impaired steering spatial navigation is unclear.

Objective: To evaluate whether vestibular loss is associated with reduced steering navigation performance in a virtual reality (VR) environment containing obstacles.

Methods: 17 ambulatory adults with vestibular loss were age/sex-matched to healthy controls.

Quantitative vestibular assessment: The development and validation of a novel, remote video head impulse test against in-clinic measurements.

Objectives: To develop a novel remote head impulse test (rHIT), and to provide preliminary data validating the rHIT vestibular-ocular reflex (VOR) gains against the in-clinic vHIT.

Methods: A convenience sample of 10 patients referred for vestibular assessment at our institution was recruited. In-clinic vHIT was used to quantify lateral VOR gains.
