This paper assesses the Extended Inverse Kinematics Posture Estimation (EIKPE) method for estimating upper limb joint angles during compound movements in exoskeleton-assisted rehabilitation. The study...
KEY FINDING: EIKPE renders a good numerical approximation of the actual posture during compound movement execution, especially for the shoulder joint angles.

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.
J Biomech, 2017 • April 11, 2017
This study aimed to quantify anthropometric parameters in individuals with SCI and examine the effects of injury duration and obesity. The results indicate that mass distribution and tissue compositio...
KEY FINDING: Chronic SCI is associated with a shift in mass proportion from lower limbs to the trunk and upper arms, and decreased lean mass proportion, especially in the trunk.
Arch Phys Med Rehabil, 2017 • October 1, 2017
The study quantified and compared spinal curvature and scapulothoracic and glenohumeral kinematics throughout the MWC propulsion cycle while individuals with SCI were seated at 2 different seat dump a...
KEY FINDING: Participants had significantly less lordosis in the 14° condition for all propulsion events.

The study investigates the impact of body weight support (BWS) on gait patterns in healthy individuals during overground walking using a cable-based robotic system (FLOAT). Results indicate that parti...
KEY FINDING: Healthy individuals maintain consistent walking kinematics even when unloaded by half their body weight, suggesting the support system permits physiological gait.
Clin Biomech (Bristol, Avon), 2004 • March 1, 2004
The purpose of this study was to estimate the loading environment for the distal femur during a novel standing exercise paradigm for people with spinal cord injury. A static, 2-D model was developed t...
KEY FINDING: Active-resistive stance resulted in maximal distal femur compression estimates of ~240% of body weight.
Journal of NeuroEngineering and Rehabilitation, 2005 • May 31, 2005
This study systematically compares a traditional linear muscle model and two contemporary nonlinear models using sensitivity analysis to examine how each model's parameters influence select simulated ...
KEY FINDING: The linear model parameters clearly influence either simulated force magnitude or speed properties, consistent with previous parameter definitions.
Eur Spine J, 2006 • January 1, 2006
The study used a biofidelic whole cervical spine model to simulate frontal impacts at varying severities (4, 6, 8, and 10 g) to quantify canal pinch diameter (CPD) narrowing. Dynamic impact CPD narrow...
KEY FINDING: Frontal impact caused significant dynamic CPD narrowing at C0-dens, C2-C3, and C6-C7 intervertebral levels.
J Appl Physiol, 2006 • March 1, 2006
This study evaluated three mathematical models for predicting the force of electrically stimulated paralyzed muscles in individuals with chronic spinal cord injury (SCI). The models included a linear ...
KEY FINDING: Nonlinear models more accurately predicted paralyzed muscle force-time profiles than the linear model.
Journal of NeuroEngineering and Rehabilitation, 2006 • February 28, 2006
This study examined the effects of powered ankle-foot orthoses on the walking patterns of individuals with incomplete spinal cord injury. The orthoses provided plantar flexion assistance, and the stud...
KEY FINDING: Powered ankle-foot orthoses increased ankle angle at stance push-off compared to passive orthoses.
