Parkinson Disease (PD) Clinical Trial
Official title:
CODY (Co-design for You): An Immersive Technology Tool for Experiencing and Assessing Home Alterations for Veterans With Movement Disabilities and Disorders
CODY (co-design for you) is a Virtual Reality (VR) tool and Application Programming Interface (API) which uses an immersive, interactive environment for using, experiencing and co-designing home alterations. The aim of this research is to assess the efficacy of using CODY to aid and enhance the ability of adults with Parkinson's disease (PD) to experience and choose appropriate home modifications.
Accessible housing is a widespread need in this country. This is particularly true among
those persons with mobility impairments and movement disorders. While design and construction
guidebooks exist for modifying homes for people with disabilities, there are also many
documented instances where a standard, "by-the-book" alteration or assistive technology did
not support the need or condition of the particular individual it was intended for. Just as
occupational therapists recognize that a critical component of successful rehabilitation
assistance is a person-centered plan that facilitates individualized solutions, likewise
diverse design (or home alterations/modification, referred here as HM) approaches which
approximate a person-centered plan also provide a more effective fit for persons with
disabilities. A "one-size-fits-all" approach is not comprehensive for the diverse disability
community.
This research entails the design and development of CODY (co-design for you), a Virtual
Reality (VR) tool and Application Programming Interface (API), which uses an immersive,
interactive environment for using, experiencing and co-designing home alterations. The
'co-design' nature of CODY denotes that persons with movement disorders, such as Parkinson's
disease can: virtually interact with and experience a home alteration/modification (HM) in a
virtual, simulated environment; have multiple variations of a HM that the user can choose
from; and is able to assess and manipulate the HM for appropriateness to one's need and
circumstances before actually installing devices or making modifications to one's own home.
As such, CODY is a new assistive technology that aids and enhances the ability of individuals
with disabilities to live in adapted homes that supports their needs.
This study focuses on movement disorders faced by persons with Parkinson's disease (PD) to
demonstrate how effective CODY may be for those with major movement challenges, characterized
by tremor, bradykinesia, postural instability, and freezing of gait (FoG). Collectively,
these symptoms increase fall risk, fear of falling and impact the quality of life when
compared to other age-matched non-PD adults. While clinical observations suggest that
attributes of the physical interior environment may make daily activities easier or harder
for persons with PD, few studies have actually examined the impact of specific changes in
interior design on an individual's performance. One research study revealed that FoG, one of
the major contributors to falls, was induced by doorways. Another study similarly revealed a
significant increase in doorway-provoked FoG indicators by decreasing doorway width.
The aims of this research are: (1) To develop the Virtual Reality-based CODY tool and
corresponding API; and (2) To assess the efficacy of using CODY to aid and enhance the
ability of persons with PD to experience and choose appropriate home modifications. The
underlying purpose of CODY is to provide opportunities for the growing population of persons
with movement disabilities and disorders to actively engage in decisions affecting their
living environment. Although VR games have been used for rehabilitation and therapy purposes,
no research studies exist that demonstrate the use or effectiveness of integrated VT
simulations in allowing persons with disabilities to interactively design residential
alterations. The study team's expectation is that CODY will not only be successful in this
short-term pilot study, but will lead to further refinement, development and, potentially, a
commercial product. The investigators envision CODY's integrated, immersive, and interactive
simulation will be used by neurologists, rehabilitation specialists, and occupational
therapists for working with consumers to assess and determine optimal home modifications for
those with ambulatory and other movement impairments.
