A second NSF Convergence Accelerator focused on increasing access and inclusion. The LIBERATE workshop is focused on Living Better through Rehabilitation & Assistive Technology.
As an NSF Convergence Accelerator, participants will seek to identify pathways that could be pursued by multidisciplinary teams to get solutions at least to a prototype stage in 3-5 years. The long-term goal from this workshop is to kickstart the next wave of technologies that will empower people with disabilities.
Dr. Steele will be participating and presenting some kernels of ideas for inclusion, especially highlighting recent work from CREATE.
The goals for this workshop are to identify pathways for technology to solve or mitigate accessibility and inclusion challenges in current and emerging workplaces. As an NSF Convergence Accelerator, participants will seek to identify pathways that could be pursued by multidisciplinary teams to get solutions at least to a prototype stage in 3-5 years. The long-term goals from this workshop are to set in motion paradigm shifts that brings the percentage of individuals with disabilities participating in the workforce closer to the general population.
Dr. Steele will be presenting some ideas on inclusion in the workplace – from work environments to transportation to workforce development.
Journal Article in Prosthetics & Orthotics International
Assessments of human movement are clinically important. However, accurate measurements are often unavailable due to the need for expensive equipment or intensive processing. For orthotists and therapists, shank-to-vertical angle (SVA) is one critical measure used to assess gait and guide prescriptions. Smartphone-based sensors may provide a widely-available platform to expand access to quantitative assessments.
Assess accuracy and repeatability of smartphone-based measurement of SVA compared to marker-based 3D motion analysis.
Four licensed clinicians (two physical therapists and two orthotists) measured SVA during gait with a smartphone attached to the anterior or lateral shank surface of unimpaired adults. We compared SVA calculated from the smartphone’s inertial measurement unit to marker-based measurements. Each clinician completed three sessions/day on two days with each participant to assess repeatability.
Average absolute differences in SVA measured with a smartphone versus marker-based 3D motion analysis during gait were 0.67 ± 0.25° and 4.89 ± 0.72°, with anterior or lateral smartphone positions, respectively. The inter- and intra-day repeatability of SVA were within 2° for both smartphone positions.
Smartphone sensors can be used to measure SVA with high accuracy and repeatability during unimpaired gait, providing a widely-available tool for quantitative gait assessments.
