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.

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.
Journal of NeuroEngineering and Rehabilitation, 2012 • May 6, 2012
This study compared the effectiveness of joint kinematics and center of mass (COM) acceleration feedback for controlling standing balance using functional neuromuscular stimulation (FNS) in individual...
KEY FINDING: Compared to constant stimulation, feedback control systems using joint kinematics, COM acceleration, or a combination reduced the need for upper extremity support by 51%, 43%, and 56%, respectively.
The Journal of Spinal Cord Medicine, 2017 • April 1, 2017
This study explored the impact of neurological injury level on walking performance with different un-powered exoskeletons, focusing on trunk muscle activity and motion patterns. The main findings reve...
KEY FINDING: The patient with the T8 injury used their trunk muscles more when walking with all the exoskeletons, indicating higher effort for stability.
J Biomech, 2007 • January 1, 2007
This study compared three mathematical muscle models (linear, 2nd order nonlinear, and Hill Huxley type nonlinear) for predicting force properties in trained and untrained paralyzed soleus muscles of ...
KEY FINDING: Nonlinear models, especially the Hill Huxley type, predict paralyzed muscle force properties more accurately than linear models.
Clin Neurophysiol, 2007 • June 1, 2007
This study investigated how stimulation frequency and muscle fatigue affect the relationship between force output and stimulation intensity in human quadriceps muscles during FES. The key finding was ...
KEY FINDING: The relationship between muscle force and stimulation intensity is exponential.
Br J Sports Med, 2007 • April 30, 2007
This study investigated the shoulder joint kinetics of elite wheelchair tennis players during flat and kick serves, comparing them to able-bodied players to assess injury risk and inform coaching prac...
KEY FINDING: Wheelchair players generate similar pre-impact absolute racquet velocities in both flat and kick serves, but with different horizontal and lateral components.
Journal of NeuroEngineering and Rehabilitation, 2008 • April 26, 2008
The study aimed to investigate the biomechanics of the hip, knee, and ankle during progressive resistance cycling in SCI subjects to detect and measure muscle fatigue, hypothesizing that knee power ou...
KEY FINDING: Ankle and knee power outputs decreased with increasing resistance, while hip power output increased.
IEEE Trans Neural Syst Rehabil Eng., 2008 • June 1, 2008
This study used a musculoskeletal model to simulate the effects of FES on shoulder and elbow function in individuals with C5 SCI. The model helped identify a set of three 'essential' muscles (serratus...
KEY FINDING: A muscle set consisting of the serratus anterior, infraspinatus and triceps would enable the greatest range of relevant movements.
Am J Phys Med Rehabil, 2008 • December 1, 2008
The study evaluated manual wheelchair propulsion across different level ground conditions to understand the impact of terrain on propulsion biomechanics. The results showed that propulsion forces and ...
KEY FINDING: Propulsion frequency was significantly greater during both concrete conditions than either tile or carpet ground conditions.
