Crouch gait, one of the most common gait pathologies among cerebral palsy (CP) is characterized by excessive knee flexion during stance phase that worsens over time and decreasing walking efficiency. CP patients in jump-knee gait have similar features to the individuals in crouch gait but exhibit a normal knee moment during midstance. Oxygen cost is the most reliable oxygen expenditure measurement...
We have developed a vector Doppler ultrasound imaging method to directly quantify the magnitude and direction of muscle and tendon velocities during movement. The goal of this study was to evaluate the feasibility of using vector Tissue Doppler Imaging (vTDI) for estimating the tibialis anterior tendon velocities during dorsiflexion in children with cerebral palsy who have foot drop. Our preliminary...
While society is partly responsible for a feeling of isolation among children with learning disabilities, this isolation is exacerbated by the child's inability to adjust psychosocially. The authors hypothesize that social inclusion will be a natural outcome if technology can restore or assist the ability of basic self-expression and self-growth. One of the most promising methods of expression for...
Idiopathic toe walkers are children whose heels do not touch the ground during walking, but who do not have any neurological deficit to explain this. The stretch reflexes for these children are normal, so that the toe walking appears to be voluntary. These children often suffer social problems. Many of these children who are not treated and some during treatment, are likely to develop a dasiaBouncy...
