    Assessment of the ISO Impact Damping Test
    (Georgia Institute of Technology, 2012) Sprigle, Stephen ; Chung, Bummo ; Meyer, Tobias
    The ISO impact damping test characterizes wheelchair cushion abilities to reduce impact loading on issues and to help maintain postural stability, reporting the number of rebounds greater than 10% of the peak impact acceleration and the ratio of the 2nd to 1st rebound. Based upon our analysis, 3 critical issues have been identified. 1) Impact magnitude should be part of the analysis. 2) Impact should be used instead rebound accelerations. 3) Oscillation from impact is not a simple 2nd order damped harmonic, instead several natural frequencies are embedded in the damped oscillation. In conclusion, ISO should utilize impact accelerations and more complex analysis to characterize the damping properties of wheelchair cushions.

    Mobility Metrics for Manual Wheelchair Use in Everyday Life
    (Georgia Institute of Technology, 2010-06) Lopez, Ricardo A. ; Sonenblum, Sharon Eve ; Sprigle, Stephen
    In this study, a method for the robust detection of manual wheelchair movement with accelerometer-based data logging is used to obtain metrics of wheelchair mobility that complement mean- and total-distance-only based measurements. It is found that these metrics, that include distance, time and number of activity bouts, provide better understanding of everyday use of manual wheelchairs by shedding more light into how users operate their wheelchairs in their daily lives.

    Anatomical Model Propulsion System: Measuring Manual Wheelchair Efficiency
    (Georgia Institute of Technology, 2010) Dao, Phuc ; Sprigle, Stephen ; Caspall, Jayme ; Ferri, Aldo A. ; Eicholtz, Matthew ; Wang, Stan
    The goal of this project was to produce a test device and methodology capable of measuring the mechanical efficiency of manual wheelchairs. The result would provide an objective measure of wheelchair performance that are required to effectively prescribe wheelchairs and to code wheelchairs properly for reimbursement.

    iMachine: Measuring Manual Wheelchair Mass Properties
    (Georgia Institute of Technology, 2010) Eicholtz, Matthew ; Sprigle, Stephen ; Ferri, Al ; Caspall, Jayme ; Dao, Phuc ; Wang, Stan
    Mass properties are important parameters in dynamic systems analysis, but may be difficult to estimate for irregularly-shaped objects. Specifically, the iMachine is designed to analyze manual wheelchairs in an effort to determine the propulsion efficiency using the Anatomical Model Propulsion System (AMPS).

    Analysis of Temperature and Relative Humidity Variation in Wheelchair Cushion Monitoring Tests
    (Georgia Institute of Technology, 2009) Eicholtz, Matthew ; Sprigle, Stephen
    Clinicians need to prescribe wheelchair equipment that is tailored to the needs of the individual. Relative humidity affects friction and skin's ability to withstand loads. Increased tissue temperature increases metabolic demand and may affect tissue integrity. Need to develop ISO standards for cushion testing.
