The Journal of Spinal Cord Medicine, 2012 • May 1, 2012
This study mathematically compared compression and shear forces at the distal femur during quadriceps stimulation in standing, supine, and seated positions to inform exercise recommendations for indiv...
KEY FINDING: Standing generates the highest compressive force (240% body weight) and lowest shear force (24% body weight) at the distal femur compared to supine and seated positions.
Journal of Athletic Training, 2012 • October 1, 2012
This study developed a cadaveric neck model to simulate head-first impacts in sports and investigate biomechanical responses and failure mechanisms. The research found that local compression force pea...
KEY FINDING: The first compression force peaks at the impact barrier, occipital condyles, and neck occur earlier than global compression peaks.
PLoS ONE, 2013 • February 28, 2013
The aim of this study is to evaluate if the energy cost of walking (CW) in a mixed group of patients with neurological diseases, almost 6 months after discharge from rehabilitation wards, can predict ...
KEY FINDING: The study found that the energy cost of walking (CW) is a predictor of walking performance in the community, as measured by the Walking Handicap Scale (WHS).
The Journal of Spinal Cord Medicine, 2013 • January 1, 2013
The study adapted a computerized posturography system to assess seated balance in individuals with spinal cord injury (SCI) and compared it with traditional clinical balance tests. The results indicat...
KEY FINDING: Seated posturography showed a stronger correlation with the neurological level of the spinal cord lesion compared to the routinely used clinical tests.
The Journal of Spinal Cord Medicine, 2013 • January 1, 2013
This study assessed the effects of external cues on the walking ability of independent ambulatory participants with spinal cord injury (SCI). The results showed that external cues, particularly visuot...
KEY FINDING: Participants showed a significant increase in walking speed, stride length, and cadence when using external cues, especially visuotemporal cues, compared to the uncued condition.
J Neurosci Methods, 2014 • January 30, 2014
This paper details the construction, surgical implantation, and validation of a pelvic orthosis in rats, designed to facilitate direct force application for brain-machine interface and rehabilitation ...
KEY FINDING: The pelvic implant orthosis can be constructed from readily available standard machine parts.
J Biomech, 2014 • January 3, 2014
This study introduces a custom biomechanical model to quantify upper extremity joint dynamics in pediatric manual wheelchair users (MWU). The model was used to evaluate a 17-year-old male with SCI, re...
KEY FINDING: The subject exhibited wrist extension angles up to 60°, indicating a high degree of wrist strain during wheelchair propulsion.
Bone, 2014 • March 1, 2014
This study investigated the mechanical consequences of bone loss and simulated bone recovery in the proximal tibia of individuals with acute spinal cord injury (SCI). The results indicated that SCI-re...
KEY FINDING: Subjects lost 8.3% of their bone mineral density during the acute period of SCI.
PLoS ONE, 2014 • March 10, 2014
This pilot study investigated the relationship between shoulder pain and kinematic spatial variability during the recovery phase of manual wheelchair propulsion in individuals using a semi-circular pa...
KEY FINDING: Spatial variability was highest at the start and end of the recovery phase and lowest during the middle of the recovery path.
PLoS ONE, 2014 • May 1, 2014
This study evaluated the relationship and redundancy between gait speeds measured by the 10MWT and 6MWT after motor incomplete spinal cord injury (iSCI). While the speeds were correlated between the 6...
KEY FINDING: Walking speeds from the 10MWT and 6MWT were highly correlated, but the 10MWT speeds were generally faster.
