Preliminary reference data and analysis of visual scanning programs using the bioness integrated therapy system

Abstract

Introduction:

Deficits in visual scanning can result from various neurological or sensory conditions, disrupting the ability to gather and interpret visual information. The Bioness Integrated Therapy System offers a promising tool for screening and improving functional vision. The study aimed to provide preliminary reference data for visual scanning performance using user-paced and time-paced Bioness Integrated Therapy System programs.

Method:

Descriptive study conducted at the University of Alabama at Birmingham, Center for Low Vision Rehabilitation. Eighty healthy adults aged 19–29 and 50–59 years were included. Participants were randomly assigned to one of two age categories and completed four sets of both programs. Each session included four sets of visual scanning tasks, with familiarization and actual trials for each program. Accuracy, reaction time, and number of hits were collected following each actual trial.

Results:

Preliminary reference data were established for each program and dependent variables. Reaction time showed significant main effects for central fixation in young adults (F = 213.671, α < 0.001, η² = 0.846) and middle-aged adults (F = 225.853, α < 0.001, η² = 0.853), respectively.

Conclusions:

This study offers preliminary reference benchmarks for visual scanning using Bioness Integrated Therapy System, supporting its utility in occupational therapy for assessing and addressing scanning deficits.
