    • Dynamic Response of Wheelchair Cushions to the ISO Impact Damping Test 

      Chung, B. M. (Georgia Institute of Technology, 2009)
      The International Organization for Standardization defines tests that characterize the properties of wheelchair cushions (ISO 16840-2). The impact damping test (IDT) characterizes cushions' abilities to reduce impact loading ...
    • Handheld, Non-Contact Wound Measurement Device 

      Sprigle, Stephen; Patel, Nirmal; Joshi, Aditya; Starner, Thad (Georgia Institute of Technology, 2006)
      Repeatable and accurate wound measurement forms an important part in the assessment and treatment of chronic wounds and pressure ulcers. Current wound measurement methods span a continuum, from the ruler method which is ...
    • Impact of Tilt-in-Space Power Wheelchairs on Health, Activity, and Participation 

      Harris, Frances; Sonenblum, Sharon Eve; Sprigle, Stephen; Maurer, Christine L. (Georgia Institute of Technology, 2008)
      This paper reports the results of a pre-post outcomes study on the impact of tilt-in-space power wheelchairs on the health, activity, and participation of 5 subjects. Using a methodology which combines traditional self-reports ...
    • Introducing Asymmetry to Wheelchair Design 

      Kong, Linghua (Georgia Institute of Technology, 2005)
      This paper reports the use of asymmetry in designing the chassis of a power wheelchair. The innovative design uses and tests two kinds of power wheels and a new suspension structure. This design carefully considers features ...
    • Inventor-Driven Product Development 

      Sprigle, Stephen; Maurer, Chris; Kong, Linghua (Georgia Institute of Technology, 2010)
      Inventors of assistive technology often lack resources to support product development and this may hinder their ability to develop useful and commercially viable devices. The purpose of this on‐going project is to support ...
    • Investigation of the Lifespan for Wheelchair Cushions used on a Daily Basis 

      Rivard, David M.; Sprigle, Stephen; Linden, Maureen (Georgia Institute of Technology, 2008)
      Wheelchair cushions function to mediate seating pressures and provide postural stability. For the majority of cushions used on average 12 hours daily, the cover and interior components degrade at varying rates while ...
