EEG potentials evoked by tactile stimulation of the forearm (tactile-evoked potentials or TEPs) were recorded simultaneously from both cerebral hemispheres in a group of schizophrenics and a group of healthy control subjects. Differences between the groups were found for the early waves of the TEPs: in the control subjects the first two positive waves (P25(More)
In Duchenne dystrophy computed tomography of muscles shows total or partial replacement of normal muscle by low density tissue, presumably representing fat. It was hypothesised that female carriers would have increased fat deposition, and hence lower density readings in certain muscle groups when compared with controls. Three C.T. scans, two through the(More)
To determine whether computerised tomography (CT) offers an accurate means of following the progression of Duchenne muscular dystrophy, CT scans through the thigh and calf were done on two occasions, six months apart, for 13 boys with the disease. The results suggest that CT scans of muscles may be used as an adjunct to other methods in the accurate(More)
Goal attainment scaling (GAS) is a procedure for evaluating the effectiveness of intervention in human service programmes. The theory and procedure of GAS are described, and its strict requirements are discussed. An example application of GAS in a rehabilitation centre for physically disabled children is reported. Problems with the application of GAS as an(More)
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)
Ear differences on a task involving a simple phonetic judgement were investigated in schizophrenic subjects using both healthy normal and depressed patient control groups. A deficit in phonemic differentiation was demonstrated and appeared to be specific to the schizophrenic group. The result is interpreted as supporting the hypothesis of a central(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)
The hypothesis investigated in this study was that the symmetry of gait achieved with biofeedback therapy was maintained at follow-up, which ranged from 18 to 24 months later. The approach adopted was to measure average heel force on the hemiparetic side and to measure the temporal asymmetries in gait from video recordings. It was found that most of the(More)
The perception by schizophrenic patients of stimuli with more than one feature (dimension) was investigated using psychiatric and non-psychiatric control groups. Indices of the ability (a) to make use of redundant stimulus cues, (b) to 'screen out' or filter irrelevant stimulus features, and (c) to scan the perceptual field for relevant stimulus features,(More)
