ItemAssessment of the ISO Impact Damping Test(Georgia Institute of Technology, 2012) Sprigle, Stephen ; Chung, Bummo ; Meyer, TobiasThe 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.

ItemMobility Metrics for Manual Wheelchair Use in Everyday Life(Georgia Institute of Technology, 2010-06) Lopez, Ricardo A. ; Sonenblum, Sharon Eve ; Sprigle, StephenIn 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.

ItemAnatomical Model Propulsion System: Measuring Manual Wheelchair Efficiency(Georgia Institute of Technology, 2010) Dao, Phuc ; Sprigle, Stephen ; Caspall, Jayme ; Ferri, Aldo A. ; Eicholtz, Matthew ; Wang, StanThe 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.

ItemiMachine: Measuring Manual Wheelchair Mass Properties(Georgia Institute of Technology, 2010) Eicholtz, Matthew ; Sprigle, Stephen ; Ferri, Al ; Caspall, Jayme ; Dao, Phuc ; Wang, StanMass 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).
