The study aimed to determine if the ML foot placement strategy is impaired in people with iSCI compared to healthy controls, and investigated the relation between ML COM kinematics and ML foot placeme...
KEY FINDING: People with iSCI showed significantly higher foot placement deviation compared to healthy controls, independent of walking speed.
Archives of Rehabilitation Research and Clinical Translation, 2022 • January 1, 2022
The study investigated the association between age at pediatric-onset SCI and years of manual wheelchair use with shoulder complex motions, forces, and moments during wheelchair propulsion. Results sh...
KEY FINDING: Increasing age at SCI onset was associated with a decrease in maximum acromioclavicular upward rotation and an increase in acromioclavicular downward/upward rotation range of motion.
Sensors, 2023 • January 18, 2023
In this study, we aim to estimate the muscle onset activation in SCI people by four strategies on EMG data. Seven complete SCI individuals participated in this study, and they maintained their stabili...
KEY FINDING: The results demonstrated that the TKEO technique could efficiently remove the electrocardiogram (ECG) and motion artifacts compared with the simple classical filtering approach.
Sensors, 2023 • February 1, 2023
This study developed a machine-learning-based methodology to estimate shoulder load in wheelchair-related activities using wearable sensors. The approach involved collecting data from participants per...
KEY FINDING: A subject-specific biLSTM model trained on a sparse sensor setup (upper arm IMU, WC IMUs, and EMG) yielded the most promising results, with a mean correlation coefficient of 0.74 ± 0.14 and a relative root-mean-squared error of 8.93% ± 2.49%.
Clin Neurophysiol, 2014 • October 1, 2014
Persons with iSCI have fewer “building blocks” for constructing muscle activity, limiting the complexity of muscle coordination for overground walking. iSCI modules cannot explain the diversity of mus...
KEY FINDING: Motor module number, composition, and activation were significantly altered in persons with iSCI as compared to AB controls during overground walking at self-selected cadences.
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.
The Journal of Spinal Cord Medicine, 2015 • January 1, 2015
The study measured knee joint stiffness and viscosity in individuals with SCI and healthy controls using the Wartenberg pendulum test. Results showed significantly greater stiffness in SCI patients co...
KEY FINDING: Patients with SCI have significantly greater joint stiffness compared to able-bodied subjects.
