Mobility Metrics for Manual Wheelchair Use in Everyday Life

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.

Clinical Usability of a Wound Measurement Device

2010 , Nemeth, Michelle E. , Sprigle, Stephen , Gajjala, Anita

Monitoring wound size is an integral component to the assessment and treatment of chronic wounds. Conventional methods, such as ruler measures and transparency tracings, for measuring wound size often have low accuracy and reliability. Newer high tech methods, while more reliable and accurate, are often expensive and difficult to use. The objective of the study was to design a wound measurement device (WMD) with the following features: ease of use, low cost, non-contact, time-saving, hand-held, reliable, and battery operated.

Study on Alleviation Pressure Cushion

2010-06 , Kong, Linghua , Sprigle, Stephen , Davis, Kim , Wang, Chao

The alleviation pressure (AP) cushion is a dynamic cushion system with three bladders at the pelvic region. The bladders can be deflated and inflated in a certain sequence to relieve the pressure on the ischial tuberosiites (IT) and coccyx/sacrum. The design of the foam base, bladder and pneumatic and electronic system of the AP cushion is discussed in this paper. And testing is conducted to verify the effectiveness of the AP cushion.

Inventor-Driven Product Development

2010 , Sprigle, Stephen , Maurer, Chris , Kong, Linghua

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 inventor and small company development of promising mobility-­‐related technologies. Specifically, the process includes: 1) an informal brainstorming session addressing technical, market and user issues; 2) formal screening of device potential and RERC capacity to assist in development; 3) invitation to engage inventors/companies with promising technologies; and 4) product testing and/or development of promising technologies. This paper describes the project’s approach and reviews activities over the past year.

Blood Flow and Pressure Changes That Occur With Tilt-in-Space

2010-06 , Sonenblum, Sharon Eve , Sprigle, Stephen

The objective of this study was to evaluate the biomechanical responses to tilt in persons with SCI. Changes in blood flow and loading at the ischial tuberosities (ITs) across different amounts of tilt were measured with Laser Doppler flowmetry and interface pressure. Pressure reduction at the IT was not present at 15°, but did occur with tilts to 30° and greater. Unlike pressure, blood flow increased with all tilts from an upright position. Only 4 of 11 participants had a considerable increase (≥10%) in blood flow at 30° tilt, whereas 9 participants did during maximum tilt (i.e., 45°-60°). Based on the results of this study, tilting for pressure reliefs as far as the seating system permits is recommended to maximize the potential for significant blood flow increases and pressure relief. The use of interim small tilts is also supported, as they also provide some benefit.
