Benefits of technology

[0011]The invention is additionally directed to a wearable system for treatment of a neurocognitive impairment, disease or disorder in a patient in need thereof, comprising: eyewear having at least one display screen configured to be visible by at least one eye of a patient and otherwise blocking a portion of the patient's view beyond the eyewear for the at least one eye; at least one camera disposed on the eyewear configured to capture video images in front of the eyewear; and a video processor electrically coupled to the at least one display screen and the at least one camera, the video processor configured to provide video images captured by the camera to the at least one display screen; the video images including a selectable prismatic effect and blocking of substantial portions of arm movement of the patient when worn by the patient.

Problems solved by technology

Individuals with spatial neglect unfortunately have poor outcomes after standard and usual rehabilitative care.
Such cumbersome “box” occluders have the disadvantages of, for example, being stationary, non-moveable during prism adaptation and non-flexible to different individuals' shoulder heights.
Further, patients have to stay very close to the box and sometimes are required to use an uncomfortable chin rest.

Prism Adaptation Treatment Using Embodiments of the Invention

[0044]In this Example, a patient underwent the Kessler Foundation Prism Adaptation Treatment (KF-PAT™) for left-sided spatial neglect (after right-brain damage) using the wearable system of the invention. The same principles and systems apply for treating right-sided spatial neglect.

I. Determination of Patient Eligibility

[0045]Patients with spatial neglect were defined by standardized assessment. To detect the presence and measure the severity of spatial neglect, the Kessler Foundation Neglect Assessment Process (KF-NAP™) was used. But the Catherine Bergego Scale, the Behavioral Inattention Test (BIT), the Bells test, the Apples test or other established tests detecting and measuring spatial neglect can also be used. Patients were not eligible if they had a history of vertigo (a result of a disturbance of the body's balancing mechanism, located in the inner ear).

Results of Prism Adaptation Therapy Session

[0083]Following the therapy session from Example 1, and as shown in FIG. 6, patients with perceptual-attentional “where” bias only (n=7) showed no improvement after KF-PAT™, while those with motor-intentional “aiming” bias only (n=5) or both types of bias (n=12) demonstrated continuous functional recovery. The results suggested that KF-PAT™ using the visual field occluder of the invention may selectively improve function in neglect patients with motor-intentional “aiming” deficits. Goedert, K. M., Chen, P., Boston, R., Foundas, A. L., & Barrett, A. M. (2014). Presence of motor-intentional aiming deficit predicts functional improvement of spatial neglect with prism adaptation.

Abstract

Provided are wearable systems and methods for treatment of a neurocognitive impairment, disease or disorder in a patient in need thereof comprising a visual field occluder useful, for example, in prism adaptation therapy.

Description

FIELD OF THE INVENTION[0001]The instant invention generally relates to a wearable system for treatment of a neurocognitive impairment, disease or disorder in a patient, and specifically to such a system employing a visual field occluder.[0002]All documents cited to or relied upon below are expressly incorporated herein by reference.BACKGROUND OF THE INVENTION[0003]Since Yves Rossetti and colleague's seminal report (Rossetti, et al. “Prism Adaptation to a Rightward Optical Deviation Rehabilitates Left Hemispatial Neglect,”Nature, 395(6698), 166-169 (1998)), many researchers and clinicians have studied prism adaptation for treating the neurocognitive disorder of spatial neglect (also known as hemispatial neglect, unilateral spatial neglect, visual inattention, visuospatial inattention, visuospatial neglect or visual neglect). Spatial neglect is a neurocognitive disorder affecting attentional control, spatial perception and representation, and motor action planning Spatial neglect comm...
