Estimating Ground Reaction Force and Center of Pressure Using Low-Cost Wearable Devices
Ambulatory monitoring of ground reaction force (GRF) and plantar center of pressure (CoP) could improve management of health conditions that impair mobility. This work presents a system consisting of 1) an insole instrumented with six force-sensitive resistors and 2) a string-based knee angle sensor. Supervised machine learning models estimated weight-normalized GRF and shoe size-normalized CoP, which were re-scaled to obtain GRF and CoP. Normalized models accurately estimated GRF and CoP despite deficiencies in force sensor data. Ambulatory use of the proposed system could enable objective, longitudinal monitoring of severity and progression for a variety of health conditions... Read more

Estimating Upper-Limb Impairment Level in Stroke Survivors Using Wearable Inertial Sensors and a Minimally-Burdensome Motor Task
Upper-limb paresis is the most common motor impairment post stroke. Current solutions to automate the assessment of upper-limb impairment impose a number of critical burdens on patients and their caregivers that preclude frequent assessment. In this work, we propose an... Read more
