Med Biol Eng Comput, 2020 • April 1, 2020
This study addresses the underestimation of maximum isometric force (MIF) in musculoskeletal models for individuals with spinal cord injury (SCI) using functional neuromuscular stimulation (FNS). A sy...
KEY FINDING: Experiments indicate that an MIF of the 50% able-bodied values commonly used is significantly lower than the identified estimates in 33 of 44 muscle groups tested.
IEEE Trans Neural Syst Rehabil Eng, 2022 • February 15, 2022
This study investigates methods to enhance reinforcement learning (RL) controllers for functional electrical stimulation (FES) of a human arm model, focusing on improving learning rates, accuracies, a...
KEY FINDING: Curriculum learning improved the number of small targets acquired by as much as 50%.
J Hand Ther, 2020 • July 1, 2020
This study established normative values for intrinsic hand strength in adults aged 21+, stratified by age and gender. These values were obtained using the Rotterdam Intrinsic Hand Myometer (RIHM). The...
KEY FINDING: Intrinsic hand strength generally declines with age, similar to grip dynamometry trends.
IEEE Trans Neural Syst Rehabil Eng, 2021 • January 1, 2021
The paper introduces an FES controller that works across a wide repertoire of movements by using methods of training that are quick and automatic. The controller takes, as inputs, the goal state of th...
KEY FINDING: Controllers trained using HER are more likely to learn to control the arm model within the specified training time.
Sensors, 2021 • April 13, 2021
This article presents a systematic review of wearable sensors and techniques used in real-time gait analysis, and their application to pathological gait. We found that heel strike and toe off are the ...
KEY FINDING: Heel strike and toe off are the most widely identified gait events, irrespective of the type of sensor used.
Clin Biomech (Bristol, Avon), 2020 • January 1, 2020
This study investigated mechanical impingement risk in manual wheelchair users with spinal cord injury during various tasks using biplane fluoroscopy and computed tomography. The findings revealed tha...
KEY FINDING: Mechanical impingement was observed during scapular plane elevation and propulsion, but not during pressure relief maneuvers in most participants.
Gait Posture, 2012 • May 1, 2012
This preliminary study characterized arm and leg coordination during treadmill walking in individuals with motor incomplete spinal cord injury (iSCI). Outcomes in individuals with iSCI selecting fast ...
KEY FINDING: Individuals with iSCI showed a 1:1 arm:leg frequency ratio, regardless of walking speed, unlike controls who varied their ratio with speed.
Journal of NeuroEngineering and Rehabilitation, 2014 • August 16, 2014
The study aimed to investigate the joints and muscles responsible for power generation and the role of antagonist co-contractions during SCI FES cycling to understand the reasons for low power output....
KEY FINDING: The primary power sources were the knee extensors of the quadriceps and the knee flexors of the hamstrings.
The Journal of Spinal Cord Medicine, 2015 • July 1, 2015
The study compared three wheelchair transfer techniques (HH-A, HH-I, and TU) to assess their impact on upper extremity joint kinetics in individuals with spinal cord injury. The HH-I technique, which ...
KEY FINDING: Hand placement is a key factor influencing upper extremity joint kinetics during wheelchair transfers.
PLoS ONE, 2014 • October 27, 2014
This study investigates the use of human walking data to control the gait of a bipedal robot, RunBot II, by establishing a causal relationship between foot contact and muscle activity. Adaptive filter...
KEY FINDING: There is a causal relationship between ground contact information from the heel and EMG, which allows the creation of a minimal, linear, analogue control system for controlling walking.
