In an attempt to investigate whether benzodiazepines at low dosage have a significant effect in reducing spasticity among children with cerebral palsy, we carried out a double-blind, placebo-controlled, cross-over study. Twelve children with either spastic diplegia or hemiplegia participated in this study. The mean age was 14 years. The restraint of passive knee movements was determined with a dynamic dynamometer and spastic stretch reflexes were measured as EMG activity in muscles stretched. Clonazepam was given at low dosage (0.02 mg/kg body weight). In each child measurements of passive restraint were made on 2 different days immediately before and 3 h after an i.m. injection of either clonazepam or placebo in randomized order. Clonazepam significantly reduced spastic restraint (P < 0.001) compared to non-significant reduction with placebo. The mean plasma concentration of clonazepam at time of spasticity evaluation was 21 mmol/l which is in the low dose range, far below conventional doses. The study thus shows a positive effect of low dose clonazepam in reducing spasticity in children when given as a single dose.

Parental age and birth order were studied in 251 patients with cerebral palsy. No parental age or birth order effects were observed in spastic quadriplegia or diplegia, but a paternal age effect was detected in those with athetoid/dystonic cerebral palsy and congenital hemiplegia. These observations indicate that some cases of athetoid/dystonic or hemiplegic cerebral palsy might arise by fresh dominant genetic mutation.

Gait analysis has radically changed the treatment of cerebral palsy. Preoperatively, it allows critical assessment of the specific pathologies of the patient. Postoperatively, it provides an accurate assessment of outcome. This assessment of outcome has in turn allowed the accurate critique of surgeries and has made it possible to discard treatments that are not useful or are perhaps even injurious. As a result of this continual reassessment of surgical techniques, several principles and insights regarding the treatment of cerebral palsy have been learned. These include (1) the importance of reestablishing normal gait prerequisites, (2) the methods of reducing the energy expenditure of the pathologic gait, (3) the importance of skeletal structures in providing the lever arm by which muscles produce moments around joints, (4) the role and importance of two joint muscles, and (5) the importance of separating abnormalities, which are emanating from the neurologic lesion, from secondary ("coping") responses. Through gait analysis, it has become apparent that diplegia and hemiplegia are noninclusive terms, each of which contain a variety of homogeneous patterns of gait. Eventually these patterns may be separated and identified and optimal treatment protocols for each pattern type developed.

We evaluated 40 children with spastic hemiplegia due to cerebral palsy for sensory function and relative limb size in the affected and unaffected upper extremities. Sensory function of each limb was evaluated with respect to stereognosis (12 objects), two-point discrimination, and proprioception. Four size measurements of each limb were made: arm and forearm circumference and forearm and forearm-hand length. This study showed that 97% of the spastic limbs had a stereognosis deficit, 90% had a two-point discrimination deficit, and 46% had a proprioception deficit. Thus sensory deficits are the rule rather than the exception in children with spastic hemiplegia. Those children with severe stereognosis deficits had significantly smaller limbs in all four measurement parameters than the children with mild or moderate stereognosis deficits. In the preoperative evaluation of children with spastic hemiplegia, severe size discrepancy is a physical examination tool that can be used as a predictor of severe sensory deficits. This information is helpful for the hand surgeon in establishing realistic surgical goals.

Two-point discrimination (TPD) was measured on eight points of the upper extremities of 220 children with cerebral palsy aged between seven and 14 years. 46 had classical diplegia, 23 had mildly spastic diplegia (without adductor spasms), 86 had hemiplegia, 26 had generalized dyskinesia, 10 had right- and four had left-sided hemiathetosis and 25 had quadriplegia. TPD was decreased in all cases compared with normal controls: slightly more for the classical forms of diplegia and on the paretic side of those with hemiplegia, slightly less in athetoid children. This adds further evidence to the authors' previous observations that sensory disorder is an integral part of the clinical picture of cerebral palsy.

One hundred and one adults (19 to 74 years of age) with cerebral palsy were interviewed and examined. There were 52 subjects with dyskinesia, 28 with spastic quadriparesis, 11 with spastic diplegia, and 10 with spastic hemiplegia. Neuromuscular dysfunction was mild in two cases, moderate in 72 and severe in 27. 76 per cent of the subjects had multiple musculoskeletal problems. In 63 per cent, these occurred under 50 years of age, suggesting that abnormal biomechanical forces and immobility had led to excessive physical stress and strain, overuse syndromes, and possibly early joint degeneration. A number of the patients had urinary complaints due to difficulties with toilet accessibility and possible neurogenic bladder. General health care seemed satisfactory for acute illnesses, but preventive health care was almost totally lacking. Treatment for the musuculoskeletal system and availability of adaptive devices were less adequate than for children with cerebral palsy.

Twins were more than three times more common in a large sample of London children with congenital hemiplegia than in the general population. This over-representation of twins could largely be explained by their higher rate of preterm birth, though twin-specific risk factors, including the consequences of a co-twin's death in utero, may also have played a part. None of the 34 co-twins who survived infancy had hemiplegia or any other form of cerebral palsy. Among 155 siblings of singletons with congenital hemiplegia, no child had hemiplegia and only one had cerebral palsy. Perhaps it is chance rather then genetic liability or an adverse environment that primarily governs who does and does not become congenitally hemiplegic.

The authors looked for differences in the energy expenditure patterns of ambulant children with cerebral palsy and spina bifida. Oxygen consumption was measured according to type of cerebral palsy or level of spina bifida lesion, and in healthy children. The rate of oxygen consumption (mL/kg/min) was significantly higher in the children with diplegia than in those with hemiplegia or with spina bifida or the healthy children. Oxygen cost (mL/kg/m) was significantly higher and velocity was significantly slower in all the groups with disability than in the healthy children. The reason children with diplegia consumed more oxygen than other children when walking may be that their abnormal equilibrium reactions impaired their balance and their ability to control their walking speed.

We describe three children with unilateral cerebellar aplasia (UCA). Deliveries at term and neonatal periods were uneventful. Pregnancy was normal in one and complicated by mild bleeding (in second and fourth month respectively) in two instances. Presenting signs were delayed motor development with marked contralateral torticollis (n = 1), hemiplegia (n = 1) and unusual head nodding (n = 1). Neuroradiological investigations revealed complete aplasia (n = 1) and subtotal aplasia (n = 2) of one cerebellar hemisphere with only a residual wing-like structure below the tentorium. There was contralateral underdevelopment of the brainstem. The infant with hemiplegic cerebral palsy had an additional supratentorial periventricular parenchymal defect, contralateral to the cerebellar hypoplasia. In view of literature reports, describing similar neuroradiological or neuropathological findings in asymptomatic individuals, it is doubtful whether UCA is responsible for our patient's problems. In our cases UCA has presumably resulted from a prenatal destructive lesion, possibly an infarct, but the timing and exact nature are unknown.

We evaluated 35 patients with cerebral palsy on the basis of MR imaging findings in the brain. The types of palsy were spastic quadriplegia (n = 11), spastic diplegia (n = 9), spastic hemiplegia (n = 2), double hemiplegia (n = 1), athetosis (n = 10) and mixed (n = 2). Of all patients, 28 (80%) generated abnormal findings. In spastic quadriplegia, although eight cases revealed severe brain damage, two cases showed no abnormal findings in the brain. One of the three had cervical cord compression caused by atlanto-axial subluxation. In spastic diplegia, the findings were divided according to whether the patient was born at term or preterm. If the patient had been born prematurely, the findings showed periventricular leukomalacia and abnormally high intensity in the posterior limbs of the internal capsule on T2-weighted images. MR imaging in spastic hemiplegia revealed cerebral infarction. In the athetoid type, half of all cases showed either no abnormal findings or slight widening of the lateral ventricle. Three cases showed abnormal signals of the basal ganglia. The reason why athetoid-type palsy did not show severe abnormality is unknown. We believe that MR imaging is a useful diagnostic modality to detect damage in the brain in cerebral palsy and plays an important role in the differentiation of cerebral palsy from the spastic palsy disease.
