A 68-year-old man was admitted to St Marianna University Hospital on account of loss of consciousness with left hemiplegia. During the hospital recovery course with a rehabilitation procedure, the patient's blood pressure was very unstable, fluctuating between high (210/110 mmHg) and low (110/70 mmHg) values accompanied by a fainting sensation. A second stroke of left hemiplegia took place 1 month later. Afterwards, his condition worsened to tetraplegia with dysarthria. Three months later, lung cancer with multiple metastasis including his left neck was found and he died from adynamic ileus 6 months after the onset of the present illness. Autopsy revealed nearly complete atheromatous obstruction and more than 50% stenosis, respectively, of his right common and internal/external carotid arteries. His intracranial arterial trunks and main branches were all patent with localized atherosclerosis of only moderate degree. The pathology of the brain existed predominantly in the right hemisphere in the border zone area between the anterior and middle cerebral arteries systematically with numerous disseminated foci of complete or incomplete necrosis, white matter and gray matter being involved independently. Involvement of centrum semiovale white matter is more extensive and intensive than that of gray matter. Of the gray matter, cerebral cortex as well as striatum, periventricular (the third ventricle) gray and cerebellar cortex was involved. The specific characteristic topography and distribution of the lesions together with their histopathology are described in detail with illustration. It is concluded that this case represents an outstanding example of hemodynamic cerebral circulatory insufficiency doubly caused by hemilateral carotid artery stenosis and repeated episodes of systemic hypotension.

This study aimed to explore the limitations of the Ashworth scale for measuring spasticity. An isokinetic dynamometer to quantify resistance to passive stretch and surface EMG was used to verify if a stretch response occurred and, if so, at what joint angle. The authors sought to determine which components of passive resistance (magnitude, rate of change, onset angle of stretch, or velocity dependence) were most related to Ashworth scores and which were related to motor function in cerebral palsy (CP). Twenty-two individuals with spastic CP (11 males, 11 females; mean age 11.9 years, SD 4.3) and a comparison group of nine children without CP (four males, five females; mean age 11.3 years, SD 2.5) participated in the study. The group with CP included those with a diagnosis of spastic diplegia, hemiplegia, or quadriplegia, distributed across Gross Motor Functional Classification Levels. Procedures included: (1) clinical assessment at the knee joint, (2) functional assessments, and (3) isokinetic assessment of passive resistance torque in hamstrings and quadriceps at three velocities. EMG data were recorded simultaneously to identify stretch responses. Detecting stretch responses using the Ashworth scale compared with instrumented measures showed near complete agreement at extremes of the scale, with marked inconsistencies in mid-range values. Ashworth scores were correlated with instrumented measures, particularly for the quadriceps, with higher correlations to the rate of change in resistance (stiffness) and onset angle of stretch than to peak resistance torque. Those with greater resistance tended to have poorer function with isokinetic relations typically stronger.

The aim of this article is to describe our clinical experience in treating muscle imbalance in 49 children with spastic upper extremity involvement. We discuss four cohorts of children treated with botulinum toxin type A (BTX-A), each with different treatment objectives. In the first group, 27 children were treated for functional improvement and, of these, 23 had a positive effect, while four had no objective benefit. In the second group, eight children were treated for purposes of presurgical planning; of these, four were referred for surgery, three continued with serial treatment and one child did not benefit from injection. The third group comprised six children who were treated to improve posture and care: in this group, four children demonstrated clear benefit and two children lost some function subsequent to injection. Finally, a fourth group of seven children were treated after acquired brain injury (three with severe tetraplegia, four with hemiplegia). In this group, all children experienced spasticity relaxation and two children with hemiplegia also gained functional benefit. In terms of adverse events, deterioration of upper extremity function was poorly tolerated but limited to the first 1--3 weeks postinjection. Grip strength or thumb grip were diminished if too high doses were used. Overall, our results with BTX-A were rewarding in children with no fixed contracture, good motor learning capacity and high motivation to train. Additionally, BTX-A treatment has proven valuable for counteracting spasticity in children with acquired brain injury. This treatment modality may not, however, be an appropriate treatment option for all children with severe upper extremity spasticity, due to the shorter duration of effect and the potential reduction in functional abilities seen in this cohort. In all cases, the selection of muscles to be treated needs careful clinical assessment. Dynamic EMG analysis should be performed whenever required to aid muscle selection, especially in children with spasticity combined with dystonia. Evaluation of M-responses suggests that for the forearm muscles, doses of BTX-A above 1.5 U/kg/muscle should not be used.

The measurement of health-related quality of life (HRQL) in children with cerebral palsy is part of an emerging discipline. Theoretical models of disability and chronic illness developed by the World Health Organization, the National Center for Medical Rehabilitation Research and others are being adapted for children. Development of HRQL measures in paediatrics lags behind the work completed with adults due to challenges unique to children, such as what domains to measure, whose perspective to address and the developmental changes inherent to children. The descriptive HRQL studies of children with moderate to severe cerebral palsy and comparisons of children with quadriplegia vs. diplegia and hemiplegia are presented. Consistent with the functional measures, no significant difference in HRQL by treatment was documented in children with spastic diplegia participating in a randomized clinical trial of selective dorsal rhizotomy. HRQL measures that are specifically tailored to cerebral palsy need to be developed. Generic and individualized measures of HRQL are currently available and while limited, may be useful for evaluating the effect of different treatments for spasticity on the quality of life in children with cerebral palsy.

The primary aim of this investigation was to assess the correlation between the POSNA Musculoskeletal Functional Health Questionnaire (POSNA) and gait analysis in children with cerebral palsy (CP). POSNA and computerized gait analysis were used to evaluate individuals with CP. Correlations were investigated between POSNA scales, gait parameters, and the Gillette Functional Assessment Questionnaire (FAQ) in 63 children (31 males, 32 females; mean age 9.17 years [SD 3.06], age range 3.75 to 16.44 years) with spastic CP. Twelve participants had hemiplegia, 29 diplegia, 12 quadriplegia, and 10 triplegia. The result of backwards stepwise multiple regression analysis indicated that the Log normalcy index (NI) was a significant predictor of the POSNA Global Function and Comfort scale. Energy expenditure (EE) did not add significantly to the prediction. The POSNA scales differentiated between the different topographical types of CP. The POSNA scale is a valid and useful clinical measure. Used in conjunction with the NI, EE, and FAQ, the POSNA scale provides a more complete appraisal of change in functioning.

The effects of recreational horseback riding therapy (HBRT) on gross motor function in children with cerebral palsy (CP: spastic diplegia, spastic quadriplegia, and spastic hemiplegia) were determined in a blinded study using the Gross Motor Function Measure (GMFM). Seventeen participants (nine females, eight males; mean age 9 years 10 months, SE 10 months) served as their own control. Their mean Gross Motor Function Classification System score was 2.7 (SD 0.4; range 1 to 5). HBRT was 1 hour per week for three riding sessions of 6 weeks per session (18 weeks). GMFM was determined every 6 weeks: pre-riding control period, onset of HBRT, every 6 weeks during HBRT for 18 weeks, and 6 weeks following HBRT. GMFM did not change during pre-riding control period. GMFM Total Score (Dimensions A-E) increased 7.6% (p<0.04) after 18 weeks, returning to control level 6 weeks following HBRT. GMFM Dimension E (Walking, Running, and Jumping) increased 8.7% after 12 weeks (p<0.02), 8.5% after 18 weeks (p<0.03), and remained elevated at 1.8% 6 weeks following HBRT (p<0.03). This suggests that HBRT may improve gross motor function in children with CP, which may reduce the degree of motor disability. Larger studies are needed to investigate this further, especially in children. with more severe disabilities. Horseback riding should be considered for sports therapy in children with CP.

This study sought to examine the reliability and validity of three generic instruments for measuring the health of children with cerebral palsy (CP) and to compare them with a disease-specific measure, the Gross Motor Function Measure (GMFM). The Pediatric Evaluation and Disability Inventory (PEDI), the Pediatric Outcomes Data Collection Instrument (PODCI), and the Child Health Questionnaire (CHQ) were completed by the primary caregivers of 115 young children with spastic CP. The GMFM was administered to the children. The mean age of the sample was 5 years 8 months (range 3:1 to 10:4) and consisted of more males (58%) than females. The PEDI scales demonstrated higher internal consistency than the PODCI and CHQ scales. In comparison with the GMFM, the PODCI transfer and mobility scale (relative validity, 62%) and the PEDI mobility scale (relative validity, 53%) detected the most significant health differences between children with hemiplegia, diplegia, and quadriplegia. The PEDI social function scale detected the largest differences in cognitive function between children with an IQ of less than 70 compared with those with an IQ of 70 or greater. The reliability and validity of these different instruments varied significantly in this patient population.

Japanese encephalitis (JE) is an encephalomyelitis involving cortex, subcortex, brainstem and spinal cord. There is paucity of studies on the neurophysiological evaluation in JE. This study aims at comprehensive evaluation of EEG, sensory and motor evoked potentials, nerve conduction and electromyography; and correlate these with clinical findings. Sixty five patients with JE diagnosed on the basis of clinical, radiological and virological criteria were subjected to a detailed clinical evaluation during the acute stage of illness. Cranial CT scan or MRI was carried out in all the patients. All the patients underwent 10 or 18 channel EEG, motor and sensory evoked potentials to both upper and lower limbs bilaterally as well as peroneal and sural nerve conductions and concentric needle EMG. Outcome, was defined at the end of 3 months into poor, partial and complete recovery. The patient's age ranged between 2-65 years. There were 40 males and 25 female patients. Fifteen patients were less than 12 years of age. History of seizure was present in 31 patients. Quadriplegia was seen in 39 and hemiplegia in 8 patients. Muscle wasting was present in 16 patients and tendon reflexes were reduced in 12 and of mixed pattern in 14 patients. Cranial MRI revealed thalamic lesion in 38, basal ganglia in 21, substantia nigra in 30, pons in 5, cerebellum in 3 and cerebral cortex in 7 patients out of 57 patients. EEG revealed nonspecific theta to delta slowing in 45, alpha pattern coma in 5 and epileptiform discharges in 8 patients. EMG revealed fibrillations in 23 patients. Motor evoked potentials were abnormal in 34 out of 46 patients and revealed patchy and focal abnormalities comprising of unrecordable, prolonged and normal pattern. Somatosensory evoked potentials were abnormal in 8 patients only. At 3 month, 26 patients had complete, 13 partial and 15 had poor outcome. Eight patients died in acute stage and 3 were lost to followup. MEP correlated with weakness and 3 month outcome whereas EEG, SEP and EMG did not have any correlation. MEP changes were more frequent in JE and had prognostic significance.

The Melbourne Assessment of Unilateral Upper Limb Function (Melbourne Assessment) is an evaluation tool that objectively measures upper-extremity function in children with cerebral palsy (CP). This study investigates how well performance on the Melbourne Assessment relates to the child's actual performance in functional tasks. Eighteen children with CP (5 to 14 years of age; nine males, nine females) were assessed using the Melbourne Assessment and the Pediatric Evaluation of Disability Inventory (PEDI). Five children had spastic quadriplegia, eight had spastic diplegia, two had spastic hemiplegia and diplegia, two had athetosis, and one had hypotonic quadriplegia with mobile ventilator dependence. Children's performances were statistically correlated using Spearman's rho to establish the relation between these tools. Very high correlation coefficients were calculated between the Melbourne Assessment and self-care (0.939) and mobility domains (0.783) of the PEDI and the overall functional skills section of the PEDI (0.718). The Melbourne Assessment demonstrates excellent construct validity for upper limb functioning.

To study the spectrum of epilepsy in children with cerebral palsy, 105 consecutive children with cerebral palsy and active epilepsy, between 1 and 14 years of age, were studied prospectively. A detailed history and examination, electroencephalography (EEG), and computed tomography (CT) were done in all cases. The social quotient was assessed using the Vineland Social Maturity Scale. A retrospective cohort of 452 cases of cerebral palsy was studied to find the prevalence of epilepsy in cerebral palsy. A control group of 60 age-matched children with cerebral palsy but no epilepsy was also studied for comparison of the social quotient. Of the 105 children, 65 were male, 40 of 105 (38%) had a history of birth asphyxia. The mean age of onset of seizures was 18.9 months; 64 (60.95%) had seizure onset before 1 year of age. Children with myoclonic seizures (P < .05) and infantile spasms (P < .01) had seizure onset significantly early in life. Generalized seizures were the most common, followed by partial seizures, infantile spasms, and other myoclonic seizures. Seizures were controlled in 45 (58.1%) children, and polytherapy was required in 40 children. EEG and CT abnormalities were seen in 70.5% and 61% of the children. Seizure control was achieved in 74% of the patients with a normal to borderline social quotient compared with 48.7% with a social quotient less than 70. Social quotient values had a positive correlation with age of onset of seizures (P < .01) and with better control of seizures (P < .01). Of the cohort of 452 children, 160 (35.4%) had epilepsy. The maximum incidence (66%) was seen in children with spastic hemiplegia, followed by quadriplegia (42.6%) and diplegia (15.8%). Epilepsy in cerebral palsy is seen in about one third of cases; it is often severe and difficult to control particularly in children with mental retardation.
