Error-enhanced Learning & Recovery in 2 & 3 Dimensions
Shirley Ryan AbilityLab
Summary
This study is being done to see how errors lead to improvement. Specifically, we are evaluating the errors stroke participants make during an upper extremity exercise program when reaching for a target using their affected arm. Once we understand the participant's reaching errors, we plan to create a customized reaching exercise according to the individual's specific error tendencies which will lead to better performance on movement ability after training.
Description
The neuroplasticity of motor re-learning is a key pathway for recovery in neurorehabilitation. One critical challenge to devising treatment plans for motor recovery is the wide variation that exists between individuals, across movement repetitions, and even within movements. Development of a learning model that looks at these factors would better relate diagnoses to treatments, providing personalization and efficiency to therapy. This proposal aims to advance rehabilitation by building a modeling framework that explores the trends and exploits a fundamental learning process - error. Our goal i…
