1/53. Thalamic stimulation for choreiform movement disorders in children. Report of two cases.Surgery for movement disorders is most commonly performed in patients with dyskinesia and tremor associated with Parkinson's disease or in those with essential tremor. The role of ablative surgery or deep brain stimulation in patients with choreiform movements is poorly defined. The authors placed thalamic stimulation systems in two children with disabling choreiform disorders due to intracerebral hemorrhage or cerebral palsy. Each patient displayed choreiform movements in the upper extremities both at rest and with intention, which interfered with daily activities and socialization. Both children obtained significant improvement in their choreiform movements, and their upper extremity function improved with no incidence of morbidity. Thalamic stimulation appears to be a promising and nonablative approach for children with choreiform movement disorders.- - - - - - - - - - ranking = 1keywords = movement (Clic here for more details about this article) |
2/53. Motor benefit from levodopa in spastic quadriplegic cerebral palsy.We report on a 16-year-old girl with spastic quadriplegic cerebral palsy associated with premature birth and typical periventricular leukomalacia, who had a dramatic improvement in motor function after treatment with carbidopa/levodopa. Kinematic and electromyographic analyses of reaching movements demonstrate that levodopa decreased muscle co-contraction, decreased unwanted movements, and improved her ability to maintain a steady arm posture. These findings suggest that levodopa be considered as an adjunct therapy for the treatment of spastic quadriplegic cerebral palsy.- - - - - - - - - - ranking = 0.22222222222222keywords = movement (Clic here for more details about this article) |
3/53. Reorganization of the motor cortex in a patient with congenital hemiparesis and mirror movements.Abnormal branching of corticospinal fibers from the unaffected motor cortex is responsible for mirror movements in patients with congenital hemiparesis, but it is unknown which mechanisms enable these patients to lateralize motor activity. Using multiunit electromyographic analysis and transcranial magnetic stimulation, the authors provide evidence for nonbranched crossed and uncrossed corticospinal projections and intracortical inhibition of the mirror hand. They propose that this remarkable reorganization of the unaffected motor cortex helps these patients to reduce mirror movements.- - - - - - - - - - ranking = 0.66666666666667keywords = movement (Clic here for more details about this article) |
4/53. Antiphospholipid- associated recurrent chorea and ballism in a child with cerebral palsy.We present the case of a 9-year-old female with cerebral palsy and repeated episodes of ballism associated with antiphospholipid and anticardiolipin antibodies. She was treated unsuccessfully with varying medications, including neuroleptics, anticholinergics, antiepileptics, dopamine, dopamine agonists, and monoamine oxidase inhibitors. Intravenous immunoglobulin and corticosteroids led to resolution of the movements. We postulate an immune mechanism of disease for ballism associated with antiphospholipid and anticardiolipin antibodies.- - - - - - - - - - ranking = 0.11111111111111keywords = movement (Clic here for more details about this article) |
5/53. Motor control testing of upper limb function after botulinum toxin injection: a case study.OBJECTIVE: To evaluate changes in upper extremity function in a hemiparetic patient after treatment with botulinum toxin (BTX) using motor-control testing (MCT) techniques. DESIGN: Interventional with longitudinal study, open label. SETTING: A children's hospital and a motor-control laboratory at a major academic center. PARTICIPANTS: A 16-year-old male with right hemiparetic cerebral palsy and a healthy 12-year-old control subject. INTERVENTIONS: BTX injections to the elbow and wrist flexors. MAIN OUTCOME MEASURES: MCT was used to examine 4 upper extremity movements: forward reach, bilateral rhythmic movements (both muscle homologous and direction homologous), isometric pinch, and hand tapping. The patient was tested before treatment and at 2, 4, 6, 12, 18, and 24 weeks after treatment. In addition, range of motion (ROM), the Ashworth scale of spasticity, Functional Independence Measure, and the mobility and activities of daily living (ADL) sections of the Pediatric Evaluation of the Disability Inventory were performed. RESULTS: Forward reach demonstrated little change initially despite patient reports of "feeling looser." Improvement was noted after 18 weeks, but returned to baseline level at 24 weeks. Bilateral rhythmic movements also showed slight improvement at 18 weeks. Pinch force increased significantly after 2 weeks, but declined again at 6 weeks. Improvements occurred in ROM and the Ashworth rating of spasticity, but were not temporally associated with each other or with MCT results. Functional assessment data did not change during the study period. CONCLUSIONS: Improvements in more complex motor tasks were noted after significant delay from the time of treatment, while simpler tasks demonstrated a more rapid improvement, followed by a rapid return to baseline levels. This case suggests that MCT techniques can provide quantitative and qualitative data, which can add new information about upper extremity motor disability and the outcome of treatment.- - - - - - - - - - ranking = 0.33333333333333keywords = movement (Clic here for more details about this article) |
6/53. Visual impairment due to a dyskinetic eye movement disorder in children with dyskinetic cerebral palsy.Neurological lesions that cause dyskinetic cerebral palsy (CP) commonly involve ocular movements. This report describes a group of 14 children (nine males, five females) whose CP is associated with severe dyskinetic eye movements. Ages ranged from 4 months to 13 years (mean 6.9 years). Clinical features of this eye movement disorder are discussed and defined. The visual function of these children is slow, variable, and highly inefficient. They are often misdiagnosed as blind, due to cortical visual impairment. Early recognition of dyskinetic eye moment disorder and appropriate developmental and educational management are important.- - - - - - - - - - ranking = 0.77777777777778keywords = movement (Clic here for more details about this article) |
7/53. Hyperkinetic movement disorder in an 11-year-old child treated with bilateral pallidal stimulators.Pallidal stimulation is widely used in the treatment of movement disorder in adults but is less well reported in the treatment of dystonia in children. Despite inconsistent results in the past, its use in dystonia in Parkinson's disease is again attracting interest with promising results. Bilateral as well as unilateral pallidotomies have been performed and are felt to be required in some cases of dystonia. Use of depth electrodes to provide long-term electrical stimulation to pallidum and other basal ganglia structures has recently become more widespread. This technique is felt to have a lower morbidity, especially in bilateral procedures. Here we present the case of an 11-year-old boy with severe hyperkinetic movement disorder who showed sustained improvement after bilateral pallidal stimulation implantation.- - - - - - - - - - ranking = 0.66666666666667keywords = movement (Clic here for more details about this article) |
8/53. Improvement of sleep apnea in a patient with cerebral palsy.Intrathecal baclofen (ITB) can reduce spasticity in adults and children with cerebral palsy. Benefits of ITB therapy include improved Ashworth scores, activities of daily living, and mobility. The impact of ITB therapy on sleep apnea in patients with cerebral palsy has not been reported. This case report describes a 29-yr-old female with mixed spastic athetoid quadriparetic cerebral palsy with dystonia, gross motor function IV, who had sleep apnea, requiring nightly continuous positive airway pressure. She received ITB with the goal to improve her wheelchair positioning and decrease her excessive movements. After the initiation of the ITB, reduction of her spasticity and dystonia was noted, as well as improvement of her sleep apnea. This case suggests that ITB therapy may improve respiratory function through reduction of respiratory muscle spasticity.- - - - - - - - - - ranking = 0.11111111111111keywords = movement (Clic here for more details about this article) |
9/53. Brain reorganisation in cerebral palsy: a high-field functional MRI study.Early brain damage may induce alternative organisation of cortical brain functions. This may happen even if there is no damage to the cortex. We assessed a 15-year-old girl with a perinatal left-sided subcortical lesion without cortical damage by functional MRI at 3 Tesla. The patient had congenital hemiparesis, mirrored limb movements and normal language function. Functional MRI was used to assess language using orthographic-lexical retrieval and noun-verb generation tasks, and demonstrated right-sided language dominance. Functional MRI of motor function was assessed for both hands separately, by squeezing a rubber balloon. Both hand movements induced asymmetric bilateral activation of the motor cortex, with a predominance of contralateral activation. language-associated activity is usually left-hemispheric, but was found in the undamaged right-sided hemisphere. Motor function was associated with the unusual pattern of bilateral cortical activation. The MR findings explain the clinical features and suggest widespread alternative cortical organisation in the presence of a focal lesion confined to subcortical structures.- - - - - - - - - - ranking = 0.22222222222222keywords = movement (Clic here for more details about this article) |
10/53. athetosis II: the syndrome of mild athetoid cerebral palsy.We describe 8 patients who presented with continuous, irregular movements occurring independently in individual fingers and, in some cases, toes, in the setting of mild dystonia present since early childhood and not associated with major disability. The finger movements varied from low-amplitude quivering or wriggling to larger amplitude movements in the plane of abduction-adduction as well as flexion-extension; they were asymmetrical but not unilateral. Quivering or working of the facial muscles was seen in 5 patients. Most patients reported worsening of the movements over the years, but there was no other evidence of a progressive neurological disease. We classify the movement disorder as athetosis as described by Hammond and Shaw and the syndrome as mild athetoid cerebral palsy.- - - - - - - - - - ranking = 0.55555555555556keywords = movement (Clic here for more details about this article) |
