Use of GPS and Sensor-based Instrumentation as a Supplement to Self-Report in Studies of Activity and Participation
(Georgia Institute of Technology, 2005)To obtain more accurate quantitative results when monitoring people’s daily activities we have developed a passive data monitoring system. This Wheelchair Activity Monitoring Instrument known as the WhAMI uses odometers, ... -
Kinematics of Lateral Transfers: A Pilot Study
(Georgia Institute of Technology, 2005)People with spinal cord injuries (SCI) must transfer many times daily. Despite the importance of proper transfers, researchers have not completely described the kinematics of lateral transfers. In this study, 19 male adults ... -
Non-Invasive Erythema Detection Using Spectral Imaging
(Georgia Institute of Technology, 2005)Erythema, or skin redness, seen after prolonged pressure application is a precursor to pressure ulcers. These occur in people with limited mobility and sensation including the elderly and people with SCI. Erythema is masked ... -
Introducing Asymmetry to Wheelchair Design
(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 ... -
Kinematics of Lateral Transfers: A Pilot Study
(Georgia Institute of Technology, 2005)People with spinal cord injuries (SCI) must transfer many times daily. Despite the importance of proper transfers, researchers have not completely described the kinematics of lateral transfers. Nyland et al identified ... -
Portable Gage for Pressure Ulcer Detection
(Georgia Institute of Technology, 2006)A hand held instrument has been developed and tested that can detect subtle changes in the skin properties by measuring its biomechanical response.The portable and handheld design makes it suitable for the detection of ... -
A method for identifying human-generated forces during an extensor thrust
(Georgia Institute of TechnologySpringer, 2006)Background. Involuntary extensor thrust experienced by wheelchair users with neurological disorders may cause injuries via impact with the wheelchair, lead to the occupant sliding out of the seat, and also damage the ... -
Measuring Activity and Participation in Outcomes Research
(Georgia Institute of Technology, 2006) -
Monitoring Power Upright and Tilt-In-Space Wheelchair Use
(Georgia Institute of Technology, 2006)This study examines the use of power upright and power tilt-in-space (TIS) wheelchairs. An occupancy detector, wheel revolution counter, and position sensor comprise the Wheelchair Activity Monitoring Instrument as used ... -
Methods for Analysis of Daily Wheelchair Activity Data
(Georgia Institute of Technology, 2006) -
Emerging Measures of Participation in Assistive Technology
(Georgia Institute of Technology, 2006) -
The When of user engagement
(Georgia Institute of Technology, 2006)One of the most important components in the design of new products is the inclusion of input from the end users and a large body of literature exists that describes how to identify and engage relevant stakeholders. Many ... -
Daily Mobility Patterns in Power Wheelchair Users: What Complexity Measures Can be Used to Describe Mobility Patterns?
(Georgia Institute of Technology, 2006) -
Handheld, Non-Contact Wound Measurement Device
(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 ... -
Wheelchair Cushions-The Science Behind Seating
(Georgia Institute of Technology, 2006) -
Determination of Optimal Technique to Monitor Bed Occupancy and Body Position

Multispectral Image Analysis of Bruise Age
(Georgia Institute of Technology, 2007)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 ... -
Development of Handheld Erythema and Bruise Detectors
(Georgia Institute of Technology, 2007) -
A Case Study Comparing Activity and Participation Measurement in Two Subjects
(Georgia Institute of Technology, 2007)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 ...
