Frontiers in Bioengineering and Biotechnology, 2020 • August 18, 2020
This study examined the influence of fatigue on antagonistic muscle coupling in limbs with spasticity after stroke by comparing sEMG activation and coherence between antagonist muscles during a sustai...
KEY FINDING: Maximal torque decreased significantly after the fatiguing contraction in both stroke and healthy groups, indicating muscle fatigue.
Gait Posture, 2021 • January 1, 2021
The study compared the effects of real-time biofeedback targeting propulsive force (AGRF) and trailing limb angle (TLA) on gait biomechanics in able-bodied individuals. Both AGRF and TLA biofeedback l...
KEY FINDING: Both AGRF and TLA biofeedback induced significant increases in targeted leg peak AGRF and TLA compared to baseline walking.
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.
Scientific Reports, 2020 • November 1, 2020
This study aimed to identify the principal postural and gait impairments associated with falls in patients with various neurological disorders. The strongest fall-related functional impairment was a r...
KEY FINDING: Reduced step length at slow walking speed is the best single determinant of falls in neurological patients.
Sensors, 2020 • December 16, 2020
This paper introduces a gait planning algorithm for lower limb exoskeletons that uses crutches, focusing on balance control based on the combined Center of Pressure (CoP). The algorithm determines the...
KEY FINDING: The gait planning algorithm effectively processes sensory information to determine suitable landing points for balanced walking.
Frontiers in Neurorobotics, 2020 • December 11, 2020
This study assessed the metabolic energy consumption of walking with the external components of a “Muscle-First” Motor Assisted Hybrid Neuroprosthesis (MAHNP), which combines implanted neuromuscular s...
KEY FINDING: Friction compensation reduced metabolic consumption while walking in the exoskeleton.
J Biomech, 2021 • February 12, 2021
This study aimed to determine if hand patterns during fast wheelchair propulsion correlate with shoulder pain development and if shoulder adductor weakness is linked to specific hand patterns. The res...
KEY FINDING: The hand pattern used during fast wheelchair propulsion is not significantly correlated with shoulder pain development.
Front. Bioeng. Biotechnol., 2021 • January 13, 2021
This study investigated how modifications in the display of a computer trace under user control of grasp forces can co-modulate agency (perception of control) and performance of grasp on rigid and com...
KEY FINDING: A positive correlation was observed between implicit agency (measured by time-interval estimation) and grasp performance (measured by force-tracking error) across varying control modes for each surface type.
Sensors, 2021 • February 2, 2021
This study investigated the validity and responsiveness of using a single IMU to measure the Shank-to-Vertical Angle (SVA) in individuals with incomplete spinal cord injury (iSCI) wearing an ankle-foo...
KEY FINDING: The study found that the SVA measured by the IMU is valid, meaning it accurately reflects the SVA when compared to the gold standard 3D gait analysis.
J NeuroEngineering Rehabil, 2021 • February 17, 2021
This study investigates how individuals with and without incomplete spinal cord injury (iSCI) adapt their stepping strategies under varied stability conditions during walking maneuvers using lateral f...
KEY FINDING: Persons with iSCI generally adapted to amplified and attenuated force fields with increased stability compared to persons without iSCI, particularly using increased step width and reduced center of mass excursion on maneuver initiation.
