This study tested the hypothesis that increasing hip flexion above 90 degrees would improve hand function in seated cerebral-palsied children with extensor spasticity. Hand function was measured objectively at four hip-flexion angles in an experimental group and a control group. The results showed no significant differences in performance. However, seat(More)
To test the hypothesis that the gait pattern of hemiplegic children can be made more symmetrical by a program of biofeedback therapy, 4 hemiplegic cerebral palsied children aged between 7 and 11 years were provided with auditory feedback from load-sensitive insole inserted in the shoe on the hemiparetic side. By providing the child with feedback derived(More)
A simple test rig was developed to measure the capacity of the lead-acid gel-electrolyte batteries used to power wheelchairs. Results of 166 tests revealed a wide scatter of battery life with different users and also showed that, in many cases, the two batteries used in a wheelchair became unequal in charge capacity after some time in use. It is recommended(More)
An Australian Standard for Wheelchair Occupant Restraint Assemblies for Motor Vehicles has been produced. Titled Australian standard 2942-1987, Wheelchair Occupant Restraint Assemblies for Use in Motor Vehicles, it establishes design and performance requirements for these restraints, and includes details of dynamic testing procedures. Under the Standard, a(More)
Consumers of fruits and vegetables are frequently exposed to small amounts of hormonally active pesticides, some of them sharing a common mode of action such as the activation of the human estrogen receptor α (hERα) or β (hERβ). Therefore, it is of particular importance to evaluate risks emanating from chemical mixtures, in which the individual pesticides(More)
This research was undertaken to determine the best wheelchair driving method for clients with cerebral palsy who were experiencing difficulties using displacement joysticks. The hypothesis was that adolescents with cerebral palsy would perform better in a tracking task using an isometric joystick (which has no moving parts) than a displacement joystick of(More)
The Toy Control Program for the Apple IIe microcomputer is a software and hardware package developed for the training of single-switch scanning skills. The specially designed scanning programs provide on screen visual feedback and activate a battery-powered toy to reinforce performance. This study examined whether the training of preschool subjects in(More)
The purpose of this study was to investigate the hypothesis that a lumbar pad producing extension of the lumbar spine is of value in posture support seats for children with Duchenne muscular dystrophy. Our method was to establish whether or not an increase in lumbar lordosis produced any increase in resistance to static lateral curvature of the supine(More)
The conventional wheelchair sling seat provides little or no support to the spine of a child with myopathy or neurogenic muscular weakness. As the spinal muscles become weaker scoliosis may develop with associated deformity, pain and restriction of cardio-respiratory function. If muscle weakness is severe, the resultant fully developed deformity is(More)
