[Neuropediatric emergencies--epileptic seizures and acute hemiplegia].

Status epilepticus and stroke are life-threatening neurological emergencies and immediate recognition and medical management are imperativ. There is a serious risk of neurological sequelae. To limit secondary brain damage a prolonged seizure has to be treated without delay. After a short history and clinical evaluation (principles of resuscitation) a benzodiazepine (usually diazepam or lorazepam) has to be administered and in case of persistence of seizure-activity phenytoin or phenobarbital. Blood- and urine-sample must be collected in the acute phase to perform further metabolic or toxic examinations. A paralysis with acute onset is suspicious for ischaemic or haemorrhagic stroke. A precise neurological examination is mandatory for accurate neuroradiological work-up and to initiate appropriate investigations for risk factors. These patients require an immediate interdisciplinary treatment in a tertiary care centre with neuropaediatry, neuroradiology and neurosurgery.

The effect of botulinum toxin type A on the functional ability of the child with spastic hemiplegia a randomized controlled trial.

It has been demonstrated that botulinum toxin type A (BTX-A) injections reduce spasticity and improve muscle growth in children with spasticity. It has been postulated that BTX-A allows the learning of more normal movement patterns. The aim of this study was to measure the effect of this treatment on functional ability, as measured by the Gross Motor Function Measure (GMFM), in children with spastic hemiplegic cerebral palsy. Children of 3--13 years and meeting the selection criteria were randomly allocated to the control or injection group using a matched pair design. A match constituted a child within 6 months of age with the same Modified Ashworth Score (MAS) for the gastroc-soleus and within 10% of the same goal scores on the Gross Motor Function Measure. Twelve matched pairs were enrolled. Outcomes were measured on enrolment and at 1, 3 and 6 months post injection. The time course of the response to BTX-A was assessed with measurements of the MAS, dynamic range of motion (R1) and static muscle length (R2). Motor function was assessed using the 88-item GMFM and parental satisfaction with a 10-point visual analogue scale. Within pair comparisons of the GMFM using the Wilcoxon signed rank test indicated that the treatment group made significantly greater gains than controls at 3 months (P=0.02) with even greater differences seen at 6 months (P=0.004). Using parametric statistics, the intrapair difference in proportional change of GMFM increased from 35% (4 to 65) at 3 months to 52% (17--87) at 6 months. Response to injection was confirmed by a decrease in MAS in the treatment group and very little change in controls. This difference was significant (P=0.002) at 3 months and was attenuated but still significant (P=0.016) at 6 months; the difference in proportional change decreased from 44% at 3 months to 22% at 6 months. Changes in R1 reflected those of MAS in the treatment group and deteriorated significantly over the study period in controls. Parents of children in the treatment group were more satisfied than controls, but satisfaction scores did not correlate with changes in function or technical outcomes suggesting that this may be a placebo effect. The changes in GMFM correlated with changes in technical outcomes at 3 months, suggesting a causal relationship. The intrapair differences in GMFM continued to increase even after the local response to injection had started to wane.

Gait training in hemiplegia.

Restoration of gait is a major goal in neurological rehabilitation. Before starting therapy, a comprehensive assessment is necessary to evaluate the deficits and remaining functions. A wide variety of therapeutic procedures are available and have to be adapted to the individual situation - different concepts of physiotherapy stress different features like: force exercise, reduction of spasticity, gait symmetry, utilization of equilibrium reflexes, stepping automation, endurance training, repetition of rhythmic movements, etc. The spectrum of available therapies was recently widened by treadmill training, with partial body-weight support, locomotor pharmacotherapy, selective reduction of spasticity by botulinum toxin injections, and by musical biofeedback, which have each proved to be successful in the restoration of gait pattern. Treadmill training based on partial body weight support, combined with enforced stepping movements has proved to be successful in the restoration of gait pattern. A common problem in hemiparetic gait, is the spastic inversion of the foot. If spasticity is not severe, an ankle-foot orthosis (AFO) is the appropriate technical aid. In other cases, botulinum toxin injection into spastic leg muscles has been successfully used to improve gait functions. In hemiparetic stroke patients, auditory (musical) rhythm, as a peripheral pacing signal, resulted in a significant increase in weight-bearing stance time on the paretic side. In addition, there was an improved stride symmetry with rhythmic cueing and a normalizations of gait pattern. These methods directed to gait improvement should be combined and adapted to the individual patient's needs, in order to obtain the best results.

Suppressed cutaneous endothelial vascular control and hemodynamic changes in paretic extremities with edema in the extremities of patients with hemiplegia.

OBJECTIVE: To investigate peripheral circulatory function and its underlying mechanisms in the paretic upper extremity after a stroke. DESIGN: Case-control study. SETTING: A department of physical medicine and rehabilitation in Taiwan. PARTICIPANTS: A total of 53 hemiplegic patients (28 men, 25 women; mean age +/- standard deviation; 58.2+/-3.8y) were studied. Subjects were divided into edema and nonedema groups. The edema group included 29 hemiplegic patients with edematous paretic upper extremities. Twenty-four hemiplegic patients in the nonedema group did not suffer from limb edema in the paretic upper extremity. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Cutaneous microvascular perfusion responses to 3 grade levels of iontophoretically applied 1% acetylcholine (ACh), 1% ACh plus 1% N(G)-monomethyl-L-arginine (L-NMMA), and 1% sodium nitroprusside (SNP) in the skin of subjects' forearms were determined by laser Doppler perfusion measurements. Moreover, hemodynamic characteristics in the arterial and venous vessels were measured by impedance plethysmography. RESULTS: Resting arterial inflow and venous capacity, tone, and outflow in paretic extremities did not significantly differ from nonparetic extremities, but the hyperemic arterial inflow was lower in paretic extremities than in nonparetic extremities, and paretic extremities were associated with lower ACh- and ACh plus L-NMMA-induced cutaneous perfusions than nonparetic extremities. ACh-induced cutaneous perfusions also decreased much more significantly in edematous paretic extremities than in nonedematous paretic extremities, and skin vascular responses to SNP do not differ significantly between paretic and nonparetic extremities. CONCLUSION: Cutaneous microcirculatory function in the paretic upper extremity after stroke may be impaired. The impairment may occur because of decreased endothelium-dependent dilation in skin vasculature. Dysfunction in cutaneous microcirculation tends to be more pronounced in the edematous than in the nonedematous extremities.

[Hemiconvulsion-Hemiplegia-Epilepsy-Syndrome (HHE)].

The pathogenesis of HHE is likely to be caused by prolonged focal convulsions responsible for a hypoxic cerebral edema. The decreased frequency of the syndrome could be explained by usually immediate drug-induced interruption of the seizure nowadays.

Rehabilitation of patients with anosognosia for hemiplegia due to intracerebral haemorrhage.

We have studied the differences in the lesions, concomitant symptoms and ADL levels in patients in acute-stage cerebral-haemorrhage and manifesting anosognosia. Twelve of 50 patients (24.0%) presented with anosognosia. The (+) group had longer intervals between onset and the first evaluation than did the (-) group, demonstrating severe sensory disturbance. The volume of haemorrhage was significantly larger in the (+) group. Anosognosia disappeared within 3 months in all cases. In the (+) group the time until discharge was long, with the ADL level at the time of discharge being low. Therefore, it was considered that anosognosia was important as an inhibitory factor hampering rehabilitation.

Assessment of shoulder pain in hemiplegia: sensitivity of the ShoulderQ.

BACKGROUND: The ShoulderQ is a structured questionnaire designed to assess timing and severity of hemiplegic shoulder pain (HSP), in order to target pain relief effectively. It includes both verbal and visual graphic rating scale questions, simply presented for patients with language/visuo-spatial deficits following stroke. OBJECTIVE: To assess the sensitivity of the ShoulderQ to clinical improvement in shoulder pain following multi-disciplinary intervention. Design and setting. Retrospective analysis of serial questionnaires collected in the course of clinical treatment in an in-patient neurological rehabilitation unit. Subjects and interventions. Thirty consecutive adults with cognitive and communicative deficits, presenting with hemiplegic shoulder pain following acquired brain injury. Multi-disciplinary treatment was delivered through an integrated care pathway, and ShoulderQs recorded fortnightly, including at baseline and end of treatment. RESULTS: Changes on visual graphic rating scale (VGRS) were associated with verbal reports of improvement (rho 0.665, p < 0.001). Patients were divided retrospectively on the basis of their overall clinical response into responders (n = 18) and non-responders (n = 12). Responders showed significant change in both VGRS and verbal scores, whereas the non-responder group did not. A change in summed VGRS score of =3 showed 77% sensitivity and 91.3% specificity for identifying the responders, with a positive predictive value of 93.3%. Summed VGRS scores of =2 had a negative predictive value of 73.3%. CONCLUSION: In this preliminary evaluation of clinical data, the ShoulderQ appears to provide a sensitive measure of shoulder pain which is responsive to change in pain experience for those able to complete the questionnaire, despite the difficulties that many of this group of patients may have in reporting their symptoms. Set alongside previously reported test-retest reliability, the results support the utility of the ShoulderQ as a simple and practical tool for evaluation of shoulder pain in patients with severe complex disabilities.
