Ongoing Research Projects

Exploring the relationship between trip and slip and brain activity in different population groups

The primary goal is to evaluate gait stability, recovery, and the degree to which the brain’s pre-frontal lobe is engaged in online processing during an induced fall (trip and slip) with and without biofeedback cueing in healthy young, healthy old, and individuals with Parkinson’s disease.

Smarter Balance System (SBS)

The overarching goals are to 1) develop the SBS that supports multimodal biofeedback (visual and vibrotactile (touch) biofeedback) and provides real-time error magnitudes with the continuous coding scheme, 2) assess the impacts on long-term rehabilitative training for people with Parkinson’s disease who receive in-home balance exercises with assistive guidance via the SBS, and 3) quantitatively and qualitatively analyze the carry-over effects of long-term rehabilitative training with the SBS on balance performance, daily physical activities, and confidence in less fear of falling.

The effects of rehabilitation training combined with assistive technologies for individuals with post stroke

The major objective of this project is to assess short and long-term effects of exercise training combined with assistive technologies on spasticity, balance, and gait performance in individuals with post stroke.

A new fall-inducing technology platform

The primary goals of this project are to 1) develop a novel platform consisting of a split-belt treadmill to induce trip and slip perturbations and a real-time gait phase detection algorithm, 2) quantitatively assess fall recovery performance in response to unexpected trips and slips, and 3) explore the effects of an advanced alert cueing on fall recovery performance.

Development of accurate and reliable algorithms for evaluating Parkinsonian tremor

The research objectives are to 1) develop accurate and reliable algorithms for measuring tremor amplitudes and frequencies using an inertial measurement unit and 2) assess algorithms’ performance in different tremor characteristics.

Effect of resistance exercise on tremor and hand dexterity in Parkinson’s disease

The goal of this project is to evaluate the effect of progressive resistance exercise of hand and arm on hand dexterity and tremor in people with Parkinson’s disease.
