Sensitization of striatal N-methyl-D-aspartate receptors (NMDAR) has been linked to events leading to the motor response changes associated with the administration of dopaminomimetics to parkinsonian animals and patients. To determine whether tyrosine phosphorylation of NMDAR subunits contributes to the apparent long-term enhancement in synaptic efficacy of(More)
Sensitization of striatal N-methyl-d-aspartate (NMDA) receptors has been implicated in the pathogenesis of the response alterations associated with dopaminomimetic treatment of parkinsonian animals and patients. To determine whether serine phosphorylation of NMDA receptor subunits by activation of Ca2+/calmodulin-dependent protein-kinase II (CaMKII)(More)
Over the past decade, selective posterior rhizotomy has been used successfully to reduce spasticity in patients with cerebral palsy. Although clinical evaluation of these patients revealed functional improvement following surgery, more objective analysis of the outcome of this surgery was sought. Kinematic gait analysis of 14 patients with spastic cerebral(More)
OBJECT Selective dorsal rhizotomy is a neurosurgical procedure performed for the relief of spasticity in children with cerebral palsy, but its long-term functional efficacy is still unknown. The authors sought to address this issue by means of an objective, prospective study in which quantitative gait analysis was used. METHODS Eleven children with(More)
A recent increase in the popularity of selective rhizotomy for reduction of spasticity in cerebral palsy has led to a demand for more objective studies of outcome and long-term follow-up results. The authors present the results of gait analysis on 14 children with spastic cerebral palsy, who underwent selective posterior rhizotomy in 1985. Sagittal plane(More)

With the recent world-wide upsurge in running, the preponderance of research has been of a physiological nature. This is understandable when the cardiovascular benefits are considered. However, the biomechanical component is also very important, especially when trying to establish the aetiology of various musculoskeletal injuries or the principles(More)
Summary form only given. In this study, a rigid link system with three degrees of freedom was used to assess the ability of a neural net to generalize a transformation between the xyz end-point coordinates of the rigid body and the corresponding joint angles theta /sub 1/, theta /sub 2/ and theta /sub 3/. For this application, distortion can be quantified(More)
