1. The Use of Personal Assistance and Environmental Supports for Persons with a Spinal Cord Injury Melissa S. Dappen, BA, OTS Washington University School of Medicine Program in Occupational Therapy April 6, 2006

2. Introduction Nearly 250,000 people in the U.S. have a spinal cord injury (SCI) Nearly 250,000 people in the U.S. have a spinal cord injury (SCI) Most people who sustain an SCI will use a wheelchair Most people who sustain an SCI will use a wheelchair Enabling device: assists people who have difficulty ambulating to move around their environment Enabling device: assists people who have difficulty ambulating to move around their environment Disabling device: can be rendered useless by barriers in the environment and within the user Disabling device: can be rendered useless by barriers in the environment and within the user (Agree, Freedman, & Sengupta, 2004; National Spinal Cord Injury Statistical Center, 2005)

3. Types of Wheelchairs Manual Manual Who: People with enough strength in their upper extremities to propel themselves Who: People with enough strength in their upper extremities to propel themselves Power Power Who: People who cannot propel themselves or fatigue easily Who: People who cannot propel themselves or fatigue easily (Buning, Angelo, & Schmeler, 2001; Chaves, Boninger, Cooper, Fitzgerald, Gray, & Cooper, 2004; Kittel, DeMarco,& Stewart, 2003; Mann, Ottenbacher, & Fraas, 1999; Scherer & Glueckhauf, 2005; Tomita, Mann, Fraas, & Stanton, 2004) Considerations: Overuse symptoms (repetitive use disorders), fatigue, disease progression/age may result in the need to switch to power chair Considerations: Heavier, require wider spaces, transportation needs, battery concerns

4. Policy Americans with Disabilities Act (1990) gives people with disabilities equal access to the public environment (in theory)… Americans with Disabilities Act (1990) gives people with disabilities equal access to the public environment (in theory)… BUT barriers remain: BUT barriers remain: Natural environment Natural environment Transportation Transportation Policies Policies Services and assistance Services and assistance Attitudes and support Attitudes and support Work and school Work and school (Gray, Gould, & Bickenbach, 2003; Richards, Bombardier, Tate, Dijkers, Gordon, Shewchuk, & DeVivo, 1999; Whiteneck, Meade, Dijkers, Tate, Bushnik, & Forchheimer, 2004)

5. Theoretical Model/Classification Framework International Classification of Functioning, Disability and Health (ICF) International Classification of Functioning, Disability and Health (ICF) Classification that describes how people live with their health condition based on body functions and structures, activities, participation, and environment Classification that describes how people live with their health condition based on body functions and structures, activities, participation, and environment Environmental factors include: Environmental factors include: Natural environment and human-made changes to environment Natural environment and human-made changes to environment Support and relationships Support and relationships Attitudes Attitudes Services, systems, and policies Services, systems, and policies Products and technology Products and technology (Gray & Hendershot, 1999; Perenboom & Chorus, 2003)

6. Relationships between Types of Support Two types of support: Personal and Environmental Two types of support: Personal and Environmental Personal support: paid vs. unpaid Personal support: paid vs. unpaid Environmental support Environmental support Environmental modification Environmental modification Assistive technology Assistive technology Can environmental support substitute for personal assistance??? Can environmental support substitute for personal assistance??? Yes Yes Mann et al report positive results Mann et al report positive results of environmental intervention Hoenig et al report use of assistive Hoenig et al report use of assistive equipment is associated with fewer hours of help for ADLs (Agree & Freedman, 2000; Agree & Freedman, 2005; Cook & Hussey, 2002; Hoenig, Taylor, & Sloan, 2003; Mann, Ottenbacjer, Fraas, Tomita, and Granger, 1999) No No Agree et al find, in a number of Agree et al find, in a number of studies, that the greater the studies, that the greater the number of severe limitations, the number of severe limitations, the more likely a person is to use a more likely a person is to use a combination of personal care and combination of personal care and equipment equipment

7. Research Proposal - Aims Determine the relationship between the amount of assistance provided by persons and the amount provided by environmental support needed by manual wheelchair users with spinal cord injury. Determine the relationship between the amount of assistance provided by persons and the amount provided by environmental support needed by manual wheelchair users with spinal cord injury. Determine the relationship between the amount of assistance provided by persons and the amount provided by environmental support needed by power wheelchair users with spinal cord injury. Determine the relationship between the amount of assistance provided by persons and the amount provided by environmental support needed by power wheelchair users with spinal cord injury. Compare the amount of person-provided assistance and environmental support used by manual wheelchair users to the amount used by power wheelchair users. Compare the amount of person-provided assistance and environmental support used by manual wheelchair users to the amount used by power wheelchair users.

19. Discussion Correlations between ES & PA Correlations between ES & PA High correlations in PWC users, not MWC users High correlations in PWC users, not MWC users People with more severe impairments are likely to use both types of support at high levels (resulting in high correlations) People with more severe impairments are likely to use both types of support at high levels (resulting in high correlations) People with less severe impairments may pick one type of support alone in order to participate (resulting in low correlations) People with less severe impairments may pick one type of support alone in order to participate (resulting in low correlations) Comparison of ES between device groups Comparison of ES between device groups Higher use by PWC users in self-care and mobility domains Higher use by PWC users in self-care and mobility domains Modifications may be used often when at home, but not as much in the community Modifications may be used often when at home, but not as much in the community MWC users may be using less ES in home if some lower extremity strength remains MWC users may be using less ES in home if some lower extremity strength remains Comparison of PA between device groups Comparison of PA between device groups PWC users report more PA use in all domains PWC users report more PA use in all domains May be due to greater impairment, impairments of upper extremities, lack of appropriate ES May be due to greater impairment, impairments of upper extremities, lack of appropriate ES

20. Implications for Occupational Therapy OTs have a unique understanding of the interrelations between components of participation OTs have a unique understanding of the interrelations between components of participation The therapist for a person with a spinal cord must take into consideration: The therapist for a person with a spinal cord must take into consideration: The type of wheelchair being prescribed The type of wheelchair being prescribed The need and use of personal assistance and environmental support The need and use of personal assistance and environmental support How to best educate the client and loved ones How to best educate the client and loved ones What the person wants to achieve every day What the person wants to achieve every day
