Frontiers in Bioengineering and Biotechnology, 2015 • September 10, 2015
This study provides a unique characterization of joint dynamics and clinical outcomes during pediatric manual wheelchair propulsion, start, and stop tasks. Propulsion, starting, and stopping tasks dur...
KEY FINDING: Joint demands differ significantly among functional tasks, with the starting task placing the greatest demands on the shoulder.
Front. Bioeng. Biotechnol., 2015 • September 17, 2015
This study describes techniques and factors influencing car transfer and WC loading for individuals with paraplegia driving their own vehicles and using their personal WCs. Vehicle height influenced l...
KEY FINDING: Vehicle height influences hand placement during car transfers, with drivers of higher profile vehicles more likely to place their hand on the driver's seat.
Frontiers in Bioengineering and Biotechnology, 2015 • October 26, 2015
The study aimed to determine how manual wheelchair users modify propulsion mechanics with self-selected increases in speed to accommodate expected increases in reaction forces. Results indicated that ...
KEY FINDING: Increased propulsion speed was accompanied by increases in reaction force magnitude and shoulder net joint moment, along with decreased pushrim contact duration.
Front. Bioeng. Biotechnol., 2015 • November 20, 2015
This study compared scapulothoracic and glenohumeral kinematics during wheelchair propulsion, weight relief, and scapular plane abduction in manual wheelchair users with shoulder pain. The results ind...
KEY FINDING: Weight relief resulted in more internal rotation of the glenohumeral joint compared to propulsion and scapular plane abduction.
Top Spinal Cord Inj Rehabil, 2015 • January 1, 2015
This study explored the feasibility of using 3D ultrasound to assess dynamic scapular movement, comparing manual wheelchair users (MWUs) with able-bodied controls (ABs). The results showed incremental...
KEY FINDING: The study found that as the arm goes up, the shoulder blade moves in specific ways, like turning outward, rotating upward, and tilting backward.
Top Spinal Cord Inj Rehabil, 2015 • January 1, 2015
This study examined the relationship between hand contact angle, pushrim forces, and shoulder kinetics during self-selected manual wheelchair propulsion by individuals with paraplegia. The results ind...
KEY FINDING: Increased push arc was associated with greater velocity and cycle distance, and reduced cadence.
J Biomech, 2017 • February 28, 2017
This study assessed the kinematics and kinetics of FES-rowing and able-bodied rowing in relation to aerobic work performed. The FES stroke is characterized by a handle pull that precedes leg extension...
KEY FINDING: With increasing exercise intensity, able-bodied rowing increased stroke rate by decreasing recovery time, while FES-rowing maintained a constant stroke rate, with no change in drive or recovery times.
PLoS ONE, 2016 • April 26, 2016
This study explores the use of EEG to decode the attentional demands of gait in healthy individuals and patients with spinal cord injuries. The research identifies gamma band features as being signifi...
KEY FINDING: Gamma band frequencies in EEG signals are related to selective attention mechanisms during gait.
Applied Bionics and Biomechanics, 2016 • April 26, 2016
This paper introduces a hybrid approach to estimate, in real-time, the GH joint angles. This hybrid system is composed of a low-cost marker-based vision system and the rehabilitation robot, overcoming...
KEY FINDING: The results show that, even with significant errors in the marker position estimation, method accuracy is adequate for RAR.
Frontiers in Bioengineering and Biotechnology, 2016 • June 28, 2016
This editorial highlights the importance of understanding the mechanical demands and performance techniques associated with manual wheelchair (MWC) use to gain insight into upper extremity loading con...
KEY FINDING: Acute changes to the shoulder's soft tissues occur after manual wheelchair propulsion under different workload settings, impacting shoulder joint kinetics.
