Although visual feedback dominates over proprioception during voluntary movements, we do not know how the control of contact forces is affected by either sensory system. We asked subjects to perform a planar reaching task while adapting to a visuomotor rotation which induced a conflict between visio...
Active workstation use has been shown to decrease sedentary behavior in the workplace. However, a dual-task environment creates a division of focus increasing the risk of an adverse gait-related event. The current study examined lower extremity (LE) tripping descriptors during a difficult precision ...
Fatigue appears to be task dependant, as there is conflicting evidence regarding the influence of fatigue on an athletes’ lower limb agility technique. This between-study disparity may reflect the different laboratory-based or game simulation fatigue protocols employed as surrogates for game play....
In this work, we developed 2D and 3D cell-based in vitro experimental models to visualize how cellular motions and stresses are correlated during aggregation and dissemination of cellular clusters. For quantitative analyses, we utilized particle image velocimetry (PIV), traction force microscopy (TF...
The accuracy of wearable sensors for measuring kinematics during return-to-play testing has not been established. This study compared a commercially available wearable sensor system to video motion analysis for six different activities. There was generally good agreement between the two systems, wit...
Non-invasive brain stimulation techniques are typically applied at rest, but may be more effective or representative of neural changes when applied during a range of voluntary effort. We investigated the effect of voluntary drive on intracortical facilitation (ICF), short-interval intracortical inhi...
Falls are common in people with multiple sclerosis (PwMS) and important predictors of experiencing a fall include fatigue and balance. While fatigue fluctuates, clinicians rely on self-report measures administered at discrete time points to assess fatigue and by extension, fall risk. Wearable inerti...
