Dosing and Deployment Trial: A Home-based Optokinetic Treatment
Sponsor: Duke University
Summary
Several interventions exist for remediation of spatial neglect, but they have mixed evidence. Optokinetic stimulation is a bottom-up intervention; in other words, it is a stimulus-driven process, with Level A (strongest) evidence, and is recommended in clinical practice guidelines such as the American Heart Association's stroke guidelines. The studies currently published all use varing doses (number of sessions a week), did not assess the impact on mobility and risk of falls, and have not been implemented in the home setting. It is imperative to understand how to successfully implement this intervention at home, and learn how it will impact mobility in order to better support a large population of individuals living with chronic spatial neglect and who face barriers to accessing care because they require caregiver support to leave the home. This will be done using both qualitative and quantitative methods.

Optokinetic stimulation
Visual scanning (repeated eye movements) from one side of the computer to the neglected side of space. The target is 30 to 70 dots, randomly displayed (of all colors, size: 2- 4 cm) on a dark background on a computer screen.
