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 • 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%.

This study used musculoskeletal models to simulate patient lifts and estimate caregiver spinal compression with and without FNS. The results suggest that FNS can reduce the force required from caregiv...
KEY FINDING: Simulation without muscle activation predicted caregiver spinal compression approximately 1.3x the NIOSH recommended ‘Action Limit’.

This study developed a dynamic rigid body musculoskeletal model of the pelvis and pelvic limbs in a healthy chondrodystrophic dog evaluated with kinematics and kinetics during gait. The musculoskeleta...
KEY FINDING: The musculoskeletal computer model accurately replicated experimental canine angular kinematics associated with gait.
Gait Posture, 2020 • January 1, 2020
This study reports on impaired interlimb coordination during overground walking in persons with iSCI. Results from this study demonstrate that spatial and temporal interlimb coordination are impaired ...
KEY FINDING: Participants with iSCI demonstrated greater spatial and temporal asymmetry, as well as, reduced gap and phase interlimb coordination as compared to age-matched controls.
J Physiol, 2021 • August 1, 2021
Passive skeletal muscle mechanical properties of whole muscle are not as well understood as muscle’s active mechanical properties. Future studies defining the specific load bearing structures and thei...
KEY FINDING: Titin bears the majority of passive load within the single muscle cell.
The Journal of Spinal Cord Medicine, 2020 • January 1, 2020
This study compared shoulder biomechanics during forward and reverse wheelchair propulsion in people with paraplegia. The study found that reverse propulsion reduced posterior and superior shoulder jo...
KEY FINDING: Free propulsion velocity, cycle distance and cadence were similar during RW, rSW and fSW.
Front. Neurorobot., 2019 • December 2, 2019
This review discusses the potential of integrating real-time neuromusculoskeletal (NMS) models with assistive devices for spinal cord injury (SCI) rehabilitation to promote neural restoration. The uti...
KEY FINDING: Neuromusculoskeletal models can optimize muscle stimulation patterns, track functional improvement, monitor safety, and provide augmented feedback during exercise-based rehabilitation.
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, 2020 • November 4, 2020
This paper proposes a solution including customized motion capture and data elaboration with the aim of supporting medical personnel in the assessment of spinal cord-injured (SCI) patients using a whe...
KEY FINDING: The measurements computed by the SCI-APP show a good reliability for analyzing the movements of SCI patients’ propulsion wheelchair.
