Limits of Stability, Dynamic Balance, and Gait Parameters Pre/Post Intervention of Idiopathic Toe Walking Children

Sticky post

From Fall 2019 to Spring 2020, undergraduate student researchers, Nate Addonizio and Lexi Nehls, assisted with the Idiopathic Toe-Walking in children project. They had hands-on experience of assisting both the clinical team (Dr. Marybeth Grant-Beuttler and DPTs) and engineering team… Continue Reading →

Spring 2020 – Quantifying muscle fatigue and gait asymmetry of college athletes using motor units

Sticky post

This past spring 2020, student researchers (Shannon Toy, Tiffany Lubrino, Armond Gray, CJ De Leon, Amir Memarian, and Mimi Manatad) explored the effects of single leg fatigue on gait and balance in an original research project. Despite COVID-19 ending the… Continue Reading →

Engineering Therapy to assist Toe-Walkers

Sticky post

Toe walking is a style of walking in which a child walks on the balls of his/her feet without heels touching the ground.  In our lab, we are designing an intervention technique that promotes plantar extension in children. In the… Continue Reading →

Fall Risk Assessment in Stroke Patients

Here we have Christopher Hoang and Kenna Dougherty working with stroke patients in a study designed to accurately assess fall risk using functional analysis of gait and postural stability parameters. Our stroke patients are affected by varying degrees of hemiparesis,… Continue Reading →

Wearable Sensors-based Fall Risk Assessment in Older Adults

Christopher Hoang presents the research from “Gait Rehab Lab” at the Orange Research Expo for Undergraduates, Chapman University. The lab designs and fabricates the sensors and their housing, ranging from bed sore sensor applications to therapy shoes to correct idiopathic toe-walking… Continue Reading →

Fall Risk Assessment in the Elderly using GRAIL-based Sensory Perturbation

Harbir Bhatti presents his research involving Gait Real-Time Analysis Interactive Lab (GRAIL) and fall risk assessment in elderly people. Using sensory perturbations and gait parameters analysis, Harbir creates a model assessing fall risk.

Wearable Sensor-based Gait Classification in Idiopathic Toe Walking Adolescents

Here is Sharon Kim presenting her work with machine learning/deep learning algorithms and idiopathic toe-walking in adolescents. Sharon used these tools to classify toe-toe walking vs. heel-toe walking and build an accurate model.
