Assessment of upper limb function, kinematic analysis, and dystonia in patients with spastic diplegia cerebral palsy and periventricular leukomalacia. Seven children with spastic diplegia cerebral palsy and 8 controls underwent upper limb kinematics. Movement duration, average and maximum linear velocity, index of curvature, index of dystonia, and target accuracy and stability were analyzed. In the patients with spastic diplegia, Gross Motor Function and Manual Ability Classification Systems were determined, and spasticity and dystonia were rated using the Modified Ashworth and the Burke-Fahn-Marsden Dystonia scales respectively. Children with spastic diplegia demonstrated a tendency toward higher index of dystonia reflecting overflow, higher index of curvature, lower velocities, and poor target accuracy and stability. All patients showed clinical evidence of dystonia in the upper limbs. Dystonia scores correlated with the Manual Ability Classification System (r = 0.86, P = .01) and with the index of dystonia (r = 0.82, P = .02). Children with spastic diplegia cerebral palsy present dystonia in the upper limbs. This is functionally relevant and can be measured with kinematic analysis.

We studied 57 low-birth-weight premature neonates, of whom 29 suffered from perinatal asphyxia and/or infection, while the remaining 28 did not and served as controls. We measured peripheral nucleated red blood cell (NRBC) absolute numbers as well as interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF)-α cytokine serum levels at 24 h postnatally and on days 3 and 7 following birth. Fourteen of the asphyxiated/infected neonates and 12 controls had neurologic assessments at the corrected postnatal age of 18 months. We found NRBC absolute numbers and serum IL-1β and IL-6 cytokine levels at 24 h postnatally to be significantly higher in neonates with perinatal asphyxia/infection than in the controls (p = 0.022, p = 0.036 and p = 0.037, respectively). TNF-α levels did not differ. Neurologic examination at the corrected postnatal age of 18 months showed 8 out of the 14 children who had been asphyxiated/infected as neonates to have abnormal findings, while 12 children who were used as controls during their neonatal period were normal. Abnormal neurologic findings correlated with high NRBC counts and IL-1β and IL-6 levels at 24 h postnatally. In conclusion, increased NRBC counts and proinflammatory cytokine levels in asphyxiated/infected neonates represent early markers for subsequent neurologic impairment.
