Brief Summary

The Bioness Integrated Therapy System (BITS) (Bioness Inc. Valencia, CA) Touch Screen is an FDA approved device comprised of an interactive touchscreen and diverse program options to challenge patients through the use of visual motor activities, visual and auditory processing, cognitive skills, and endurance training. The purpose of this study is to enroll a small group of adults currently undergoing inpatient rehabilitation, who were admitted for an acute neurological event and present with an acute neurological visual field impairment. The primary objective is to compare any increase in visual field awareness using a prescribed regimen consisting of conventional vision exercises compared with a regimen using BITS touch screen technology. Participants will be alternately assigned into "A" and "B" groups upon enrollment. The control group "A" will be prescribed conventional (table top, pen and paper) vision interventions provided by an occupational therapist and will receive pre- and post- assessment of visual field awareness. Treatment group "B" will include a prescribed regimen with use of BITS touch screen technology. Group B participants will receive the same pre- and post- assessment of visual field awareness as Group A participants. The hypothesis is that incorporation of the BITS touch screen technology, being more interactive, will result in better outcomes for visual field awareness. This is an unblinded quasi-randomized control trial that will determine best treatment intervention for visual field impairment. Safety will be measured by the number of reported adverse events. The study period will include 6 sessions per participant, conducted at one site, with the objective of enrolling at least 30 participants to have 15 participants in each study group.

Outcome Measures

Primary Outcomes (3)

  • Bells Test

    Used to determine initial visual field awareness. The participant is presented with a standardized pen and paper assessment that includes pictures of bells and other objects. The participant has to locate and circle as many bells as they can without circling any distractors. The participant is scored on the time that it takes to complete the assessment, the number of bells that are located on both the left and right side of the page, and the number of distractors that are located. The Bells test scored on a scale of 0 through 35; the higher the score the better.

    Pre and post tests will be collected within 1 week following enrollment and within 1 week prior to discharge, approximately 1 month from baseline.

  • Kinetic Field Assessment - Field of View

    Neuro-Optometrist delivered test. Measures the density or presence of field deficits, or blind-spots, in participants using moving objects with a fixed luminance and color. Each participant has both eyes assessed (n = 2). Measured in degrees from 0-360, typical values for healthy adults are 170-200 degrees.

    Pre and post tests will be collected within 1 week following enrollment and within 1 week prior to discharge.

  • Kinetic Field Testing - Visual Field Index

    Neuro-Optometrist delivered test. Measures the density or presence of field deficits, or blind-spots, in participants using moving objects with a fixed luminance and color. Each participant has both eyes assessed (n = 2). Visual Field Index is a percentage from 0-100%, with 100% being a normal field and 0% being a perimetrically blind field.

    Pre and post tests will be collected within 1 week following enrollment and within 1 week prior to discharge.
