Cerebral palsy (CP) is the most common children and adults movement disorder that is associated with life-long disability and multiple impairments. Children with CP demonstrate poor fine and gross motor function due to psychomotor disturbances. Early rehabilitation programs are essential for children with CP and should be appropriate for the age and functional condition of the patients. Robot-assisted...
Higher specific absorption rate (SAR) values have been found in children when exposed to RF sources. It is worth noting that mass densities of each of the tissues is always used as of that of an adult person, despite the evident difference of tissue dielectric values due to the difference of water contents in each development stage. Some researchers have reported that children may exhibit higher SAR...
Electrocardiogram (ECG) represents, with the electroencephalogram (EEG), the principal bio-vital signals, providing information on the human physical condition. Although surface electromyogram (sEMG) is not classified as bio-vital, it is frequently used to integrate and increase information obtained from ECG and EEG, making these three signals the main electric-biological signals. The sEMG is widely...
Augmented reality (AR) designers have great potential to enrich children's lives through AR experiences in education and entertainment. A significant difficulty in designing for children is that tremendous physical and cognitive development occurs across the first 10 years of life, and the changes in children's capabilities and limitations impact how these users respond to AR designs. Currently, little...
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...
The aim of this study was to extract quantifiable indices characterising the ultrasound propagation and scattering in skeletal muscle, using a real-time linear array scanner in regular diagnostic use in a paediatric muscle clinic. The work attempts to quantify earlier observations, based on conventional imaging, that muscle echogenicity was increased in children with muscle disease, and that this...
A simple online system for collecting EMG data from surface recording electrodes and force data has been developed to study muscular weakness in multiple sclerosis (MS) patients and children. The parameters of force, integrated EMG, peak positive and negative amplitudes and zero-crossing frequencies are simultaneously recorded. Leg measurements show clear quantifiable differences between normal muscles...
