J NeuroEngineering Rehabil, 2021 • September 8, 2021
This study aimed to determine which kinematic variables obtained during a drinking task were associated with three clinical assessments of upper extremity functioning (ARAT, SHFT, ISCI-Hand) in people...
KEY FINDING: Wrist angle combined with movement time or smoothness explained a large portion of the variance in ARAT and SHFT scores.
The Journal of Spinal Cord Medicine, 2023 • January 1, 2023
This study validated the use of accelerometers to assess trunk control (TC) in individuals with spinal cord injury (SCI). The researchers found that specific accelerometer parameters are reliable and ...
KEY FINDING: Reliable IMU data were obtained in people with SCI and without SCI, of all accelerometer axes, metrics, and tested items of the CTCT.
Sensors, 2021 • November 6, 2021
This study introduces a sensor-based gait analysis algorithm designed specifically for SCI patients, utilizing shank-mounted inertial sensors and personalized thresholds for step and gait event detect...
KEY FINDING: The sensor-based algorithm performs similarly well for both SCI patients and healthy controls.
Sensors, 2021 • October 22, 2021
The study compares manual wheelchair (MWC) and pushrim-activated power-assisted wheelchair (PAPAW) propulsion during common over-ground maneuvers. Findings indicate that PAPAWs reduce propulsion effor...
KEY FINDING: Using PAPAWs significantly reduces propulsion effort (RMS torque) and push frequency compared to manual wheelchairs.
Scientific Reports, 2021 • October 1, 2021
This is a publisher correction for an article on ankle muscle co-contraction and postural instability in individuals with incomplete spinal cord injury (iSCI). The correction addresses errors in Figur...
KEY FINDING: The error in Figure 6(a) involved mislabeling of simulated groups in the EO and EC conditions.
Journal of Healthcare Engineering, 2021 • December 1, 2021
This study aimed to investigate the influence of subcutaneous fat thickness on the interface pressure and load distribution of buttock of seated humans. Four buttock FE models with different subcutane...
KEY FINDING: Fat tissue in the buttock could reduce the contact pressure when sitting on the rigid seat.
Frontiers in Bioengineering and Biotechnology, 2021 • November 29, 2021
This study explored the relationship between adipose characteristics and pressure injury (PrI) history in full-time wheelchair users using MRI scans to examine subcutaneous and intramuscular fat. The ...
KEY FINDING: Participants with a history of PrIs had significantly darker adipose under the ischium than surrounding the ischium compared to participants without a history of PrIs.
Journal of Orthopaedic Surgery and Research, 2021 • December 14, 2021
The study investigates the biomechanical and kinematic effects of cervical rotatory manipulation (CRM) on the spinal cord using a finite element model. The model simulated CRM in flexion, extension, a...
KEY FINDING: Lower von Mises stress was observed on the spinal cord after CRM in the flexion position, indicating reduced stress.
PLoS ONE, 2022 • January 27, 2022
This study investigated the biomechanical differences between able-bodied and SCI individuals walking in a ReWalkTM exoskeleton. The results indicated that SCI individuals exhibited reduced step lengt...
KEY FINDING: SCI group exhibited reduced step length and cadence compared to able-bodied individuals, leading to slower walking speeds within the exoskeleton.
Frontiers in Physiology, 2022 • January 5, 2022
The study presents a new gait analysis system (OMGait) that uses a smartphone camera and the OpenPose algorithm to measure gait kinematics. OMGait was found to be accurate in measuring hip, knee, and ...
KEY FINDING: OMGait can measure hip, knee, and ankle joint kinematics with relatively good accuracy using a common mobile phone camera and a personal computer using OpenPose.
