Outcomes of an Assistive Technology Intervention Among Wheeled Mobility Users

2007 , Harris, Frances , Sprigle, Stephen

This paper reports the outcomes of an assistive technology (AT) intervention among seating and mobility clients at an acute rehabilitation hospital between 2002 and 2004. Three instruments, OTFACT, PIADS, and the ATOM, were administered during baseline and assessments made at 1 and 12 months post-intervention. Results showed that the measures were not significantly correlated at baseline, post 1 and post 12 months, indicating the intervention had a dissimilar impact on their respective constructs. Results are discussed in terms of methodological implications for future outcomes studies.

A Case Study Comparing Activity and Participation Measurement in Two Subjects

2007 , Harris, Frances , Sonenblum, Sharon Eve , Sprigle, Stephen

This case study compares the differences between complementary methodologies that measure activity and participation in two subjects who use wheeled mobility devices. Data collection consisted of 1) a self-report participation measure for people with mobility disabilities - the Community Participation and Perceived Receptivity Survey (CPPRS) - and 2) a passive instrumentation data-gathering methodology that includes a global positioning system (GPS) data logger, followed by a prompted recall interview (PRI) to confirm GPS data location and query activity purpose. Many of the destination types (e.g., grocery stores) named in the CPPRS were confirmed by GPS/PRI data. Issues affecting subject responses in both methods included ambiguous categories and researcher assumptions about the nature of activity. Differences between self-report and instrumentation data are discussed as they impact understanding activity and community participation among wheeled mobility users and the development of self-report participation instruments.

Multispectral Image Analysis of Bruise Age

2007 , Sprigle, Stephen , Yi, Dingrong , Caspall, Jayme , Linden, Maureen , Kong, Linghua

The detection and aging of bruises is important within clinical and forensic environments. Traditionally, visual and photographic assessment of bruise color is used to determine age, but this qualitative technique has been shown to be inaccurate and unreliable. Spectroscopy and multi-spectral imaging have demonstrated objectivity in identifying age-dependent features. However these devices are not well suited for clinical environments. The purpose of this study was to develop a technique to spectrally-age bruises that minimizes the filtering and hardware requirements while achieving acceptable accuracy. This approach will then be incorporated into a handheld, point-of-care technology that is clinically-viable and affordable. Sixteen bruises from elder residents of a long term care facility were imaged over time. A multi-spectral system collected images at 11 wavelengths ranging between 370-970 nm that corresponded to skin and blood chromophores. Normalized bruise reflectance (NBR)- defined as the ratio of optical reflectance coefficient of bruised skin over that of normal skin- was calculated for all bruises at all wavelengths. The smallest mean NBR, regardless of bruise age, was found at wavelength between 555 & 577nm suggesting that contrast in bruises are from the hemoglobin chromophores, and that they linger for a long duration. A contrast metric, based on the NBR at 460nm and 650nm, was found to be sensitive to age and requires further investigation. Overall, the study identified four key wavelengths that have promise to characterize bruise age. However, the high variability across bruises complicates the development of a handheld detection system until additional data is available.
