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.
Frontiers in Sports and Active Living, 2021 • March 26, 2021
This study used wearable sensors to examine arm use patterns in manual wheelchair users (MWC) and able-bodied controls, focusing on static and dynamic arm movements at different humeral elevation rang...
KEY FINDING: MWC users spent significantly more time dynamic in 60–90◦and 90–120◦on the dominant arm compared to controls.
PLOS ONE, 2021 • April 23, 2021
The study compared the humeral elevation workspace of individuals with SCI who use manual wheelchairs (MWC) to age- and sex-matched able-bodied controls. Individuals with SCI spent significantly more ...
KEY FINDING: Individuals with SCI spent a significantly lower percentage of the day in 0–30˚ of humeral elevation compared to controls.
Journal of NeuroEngineering and Rehabilitation, 2022 • September 8, 2022
This study evaluated the accuracy of a novel algorithm for estimating gait speed in children undergoing rehabilitation using a single ankle-worn inertial sensor. The algorithm showed accurate gait spe...
KEY FINDING: The measurement error of the sensor-based gait speed estimation was low in both standardized (0.01 m/s) and daily life (0.04 m/s) conditions.
Sensors, 2022 • November 1, 2022
This study assessed gait capacity and gait performance in rehabilitation inpatients with stroke or iSCI using IMUs. The IMU-based gait algorithm was found to be valid for gait assessment and gait capa...
KEY FINDING: IMUs can accurately measure walking ability in patients with neurological disorders.
Top Spinal Cord Inj Rehabil, 2022 • October 1, 2022
This study investigates the impact of varying wheelchair axle positions on propulsion kinematics in individuals with C7 tetraplegia, focusing on speed, stroke frequency, acceleration, and shoulder ran...
KEY FINDING: Significant differences in speed were observed between axle position 1 (forward and up) and position 2 (forward and down), and between position 2 and position 4 (backward and up).
Journal of NeuroEngineering and Rehabilitation, 2022 • November 23, 2022
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.
