This study examined the effects of whole-body vibration (WBV) on walking function in individuals with spinal cord injury (SCI). Seventeen individuals with chronic, motor-incomplete SCI participated in...
KEY FINDING: Walking speed increased significantly after the WBV intervention.

The SMARTWheel has helped to provide the foundation for more thorough analyses of the biomechanics of wheelchair propulsion, to wheelchair ergonomics, and to understanding the mechanisms of repetitive...
KEY FINDING: The SMARTWheel transformed the nascent field of wheelchair propulsion biomechanics by allowing researchers to identify and analyze characteristics such as push-angle, peak forces and moments, and center-of-pressure.

This study investigated the impact of four different BWSLT approaches on gait quality in individuals with chronic motor-incomplete SCI. The approaches included treadmill with manual assistance (TM), t...
KEY FINDING: All BWSLT approaches improved gait quality in subjects with SCI, increasing cadence, step length, and stride length.
JOURNAL OF NEUROTRAUMA, 2009 • November 1, 2009
The study aimed to characterize a motor-driven treadmill device in conjunction with the TreadScan software system for gait analysis in mice with spinal cord injuries. The results indicated that increa...
KEY FINDING: The TreadScan software successfully differentiates sham animals from injured animals on a number of gait characteristics, including hindlimb swing time, stride length, toe spread, and track width.

The study focuses on the development and application of robotic lower limb exoskeletons, particularly those controlled by proportional myoelectric control. This control method uses the wearer's muscle...
KEY FINDING: Healthy humans can quickly adjust to walking with robotic ankle exoskeletons, ultimately using less energy.
J Biomech, 2010 • April 19, 2010
This study optimized and evaluated proportional derivative (PD) controllers for stimulating arm muscles to achieve accurate and robust reaching movements in a computational arm model. The controllers ...
KEY FINDING: Optimized PD controllers can generate accurate and efficient arm movements in a biomechanical model.

Neonatal spinalized rats can achieve autonomous weight-supported locomotion, unlike adult spinalized rats, suggesting greater plasticity in the developing nervous system. Trunk control, influenced by ...
KEY FINDING: Neonatal spinalized rats can develop autonomous weight-supported stepping, unlike adult spinalized rats.
Journal of NeuroEngineering and Rehabilitation, 2010 • August 20, 2010
This study aimed to compare kinematic data of upper limb movements during a drinking task among individuals with C6 tetraplegia, C7 tetraplegia, and a control group. The results indicated that individ...
KEY FINDING: Subjects with C6 tetraplegia performed the drinking task at a slower velocity and with more prolonged phases compared to the control group.
Spinal Cord, 2011 • March 1, 2011
The study assessed arm movement during treadmill stepping in 30 individuals with motor incomplete SCI (iSCI) before and after locomotor training (LT). The results showed that arm swing was absent in a...
KEY FINDING: Arm swing was absent during treadmill-based stepping in 60% of the individuals with iSCI
