Development of a Pressure Ulcer Prevention Beliefs Instrument for Persons with Spinal Cord Injury. Rehabilitation Institute Research Corporation (H133G010058), led by Rosemarie B. King, PhD, RN. Phillip Beatty, Project Officer.
Abstract: This project develops a measure that clinicians can use to assess the health beliefs of persons with SCI regarding pressure ulcer (PU) prevention. The goals of the study are to: (1) develop an instrument to measure PU-prevention health beliefs that is reliable by collecting qualitative data on perceptions about PU risk and seriousness, barriers to and benefits of preventive skin care, and confidence in performing skin care; (2) develop a health beliefs instrument that is structurally and theoretically valid; and (3) describe the pressure ulcer prevention beliefs of 375 persons with recent or chronic SCI. The project uses qualitative data to develop questionnaire items on perceptions about PU risk and seriousness, barriers to and benefits of predict skin-care, and confidence in performing skin care. The measure is used to describe and predict skin-care behaviors. Statistics used to determine reliability and validity of the measure include internal consistency reliability, exploratory factor analysis, Rasch analysis, and hierarchical multiple regression analyses. Findings facilitate the development of health belief-based interventions that address the multifactorial basis of risk for PU development. The addition of skin care health beliefs to risk prediction instruments should increase the predictive power of such instruments.

A Study of Biophysical and Microvascular Function of Individuals with SCI: Implications for Alternating Pressure Support Surfaces. University of Pittsburgh (H133G040222), led by David M. Brienza, PhD. William Peterson, Project Officer.
Abstract: The specific aims of this research study are to: (1) characterize blood flow control mechanisms (e.g. metabolic, neurogenic, and myogenic controls) via laser Doppler blood flow using Wavelet analysis in individuals with SCI; (2) investigate the use of alternating pressure for enhancing skin blood flow in SCI; (3) compare the effect of neurogenic control of cutaneous microcirculation on the strength of blood flow responses to alternating pressure in SCI with T-6 above and below; and (4) compare the effect of soft tissue properties on the strength of blood flow responses to alternating pressure in SCI with T-6 below and unimpaired subjects. These studies provide insight into mechanisms important to the configurations of optimal parameters for enhancing blood flow in SCI population, and provide a valid method for the evaluation of alternating pressure devices.

Daily Living Context and Pressure Sores in Consumers with Spinal Cord Injury. University of Southern California (H133G000062) led by Florence Clark, PhD, OTR. Kristi E. Wilson, PhD, Project Officer.
Abstract: This project examines the beliefs and practices underlying the activities, habits, and daily routines of 18 ethnically diverse consumers with SCI. The intent is to document how personality, lifestyle patterns and choices, and environmental context mutually interact within the individually constructed lives of consumers to influence the development of pressure sores. The problem of recurrent, medically serious pressure sores represents a key challenge to the ability of individuals with SCI to experience a full and satisfying life. Although prior research has documented that the development of pressure sores is in general linked to psychosocial and environmental variables, there is a need to obtain new, consumer-centered information about how pressure sores can be minimized through personally tailored adaptive strategies that are responsive to the opportunities and difficulties embedded in the unique sets of everyday circumstances that characterize individual lives. A variety of data collection procedures, including participant observation as well as interviews with consumers, their caregivers, and other associated persons, are analyzed to generate results that are comprehensive and trustworthy. These results are used to develop a series of applied products, including: (1) a consumer-oriented self-help manual; (2) a set of guidelines for rehabilitation practice; and (3) a lifestyle-oriented occupational therapy treatment model. Consumer representatives contribute to all aspects of the project to ensure that it is relevant and maximally useful to the target population.

Preliminary findings of the USC-Rancho Los Amigos Pressure Sore study has revealed that pressure wounds are affected by a complex, individualized interplay of protective buffers and liabilities that exist within the everyday lives of adults with spinal cord injury, and that the ability to prevent pressure sores is only as strong as the most vulnerable risk-relevant component in a person’s life. Another key finding is that persons with spinal cord injury live in a precarious balance, such that circumstances beyond their control (e.g., unexpected life events, emergence of comorbidities, or a reduction in financial resources) can eventuate in the development of a pressure sore. Additionally, and of most impact from an occupational point of view, is the discovery that a crucial risk factor is the recurrent tension between the need to achieve a full, active life and the need to constrain one’s activities to prevent pressure sores.

Missouri Model Spinal Cord Injury System. University of Missouri/Columbia (H133N000012), led by Laura H. Schopp, PhD, ABPP. Phillip Beatty, Project Officer.
Abstract: The Missouri Model Spinal Cord Injury System (MOMSCIS) is committed to developing, implementing, and evaluating innovative research promoting independent living and community integration among persons with spinal cord impairment. The study focused on the effect of a consumer-directed personal assistance services training intervention on consumer satisfaction, independent living and community integration. The study developed, implemented and evaluated the in-person Individualized Management of Personal Assistant/Consumer Teams (IMPACT) workshop. Workshop participants received information on preventing and treating secondary medical conditions, including pressure sores, urinary tract infections, bowel and bladder management, autonomic dysreflexia, pain management, chronic fatigue, and thermoregulation, and information on relationship issues, such as hiring and firing, communication styles and strategies, assertiveness, and team building. Study objectives were: 1) to determine the effect of the IMPACT workshop on consumer satisfaction, the incidence of secondary conditions, activity, and participation (as defined by the ICF); 2) to determine the effect of the IMPACT workshop on personal assistants’ job satisfaction, job stress and attrition; and 3) to provide online resources to the disability community, including an online personal assistant training manual for consumers and assistants, and an online resources database. Activity and participation were measured by the PARTicipation Survey for persons with Mobility Limitations (PARTS/M).

Moussavi, R. M., Garza, H. M., Eisele, S. G., Rosriguez, G., Rintala, D. H. (2003) Serum levels of vitamins A, C, and E in persons with chronic spinal cord injury living in the community. Archives of Physical Medicine and Rehabilitation, 84(7), 1061-1067. NARIC Accession Number: J45732.
Produced under grant number: H133B40011
Abstract: This study compares serum levels of vitamins A, C, and E among individuals with spinal cord injury to those levels normally found in the general population and describes their association with demographic and injury-related data, health status, nutritional behaviors, and occurrence of pressure ulcers. A significant number of participants (16 to 37 percent) had serum levels below the norm for each vitamin. Being older or older at onset of injury was associated with higher serum levels of vitamins A and E. Vitamin A was also related to better function and health status and with not having a pressure ulcer with the past 12 months. No relationships were found with vitamin C.

Produced under grant number: H133G10101
Abstract: Describes study conducted to determine the influence of lesion level on shoulder muscle electromyographic activity during a depression raise maneuver in men with spinal cord injury. The depression raise maneuver is commonly performed to relieve skin pressures and avoid skin ulceration. Participants were grouped according to level of injury: C7 tetraplegia, C6 tetraplegia, high paraplegia, and low paraplegia. Results showed that individuals with tetraplegia lacked normal strength of the primary muscles used by those with paraplegia for the depression raise. Alternate methods of pressure relief should be considered for people with tetraplegia.

Produced under grant number: H133N50009
Abstract: Study examined the relationship between alcohol abuse history and (1) depression and acceptance of disability and (2) the occurrence of pressure sores during the first 3 years following spinal cord injury. One hundred seventy-five people completed the Michigan Alcoholism Screening Test (MAST), the Inventory to Diagnose Depression (IDD), and the Acceptance of Disability Scale on admission to an inpatient rehabilitation program. One hundred five participants were evaluated for pressure sores. Results indicate that alcohol abuse was not associated with depression or disability acceptance. Severe alcohol abuse history was associated with pressure sores over the 3 years.

Produced under grant number: H133N000015
Abstract: Study compares the incidence of medical complications secondary to spinal cord injury (SCI) in patients with nontraumatic and traumatic SCI. Prospective data collected included medical complications, injury characteristics, demographics, and rehabilitation outcomes. Individuals with traumatic SCI developed medical complications at a higher frequency in the following areas: deep vein thrombosis, pressure ulcers, autonomic dysreflexia, pneumonia, orthostatic hypotension, and spasticity. Individuals with nontraumatic SCI were more likely to have wound infections during rehabilitation. No significant differences were found between the 2 groups in the incidence of depression, urinary tract infection, heterotopic ossification, pain at admission, and gastrointestinal bleeding.

Abstract: Study examining relations between patterns of turning during sleep and tissue-interface pressures at 10 anatomical points prone to pressure sores. Participants were 20 healthy individuals. Results indicate that turning was related to REM-NREM transitions. The incidence of movement was found to be linked to levels of tissue anoxia. This linkage is modeled as a logarithmic relationship between maximum period of immobility and tissue anoxic level.
