1 of 1 DESCRIPTION Our patient is a girl with pantothenate kinase associated neurodegeneration 1 and autosomal recessive transmission. She has marked contractions of the lower facial muscles and severe contraction of calf muscles, with both feet in a crooked position, more evident on the right side. Since infancy, she walked abnormally and was unstable when standing, due to progressive hyperton...

The purposes of this study were to investigate the effect of movement repetitions on resistive torque during passive isokinetic dynamometry of the knee and to determine the role of electromyographic activity in the stretched muscles on the torque measurements. Ten persons with multiple sclerosis and hypertonia of the knee muscles were compared with 10 healthy age- and gender-matched control sub...

We assessed the impact of videotape analysis on scoring of the Hypertonia Assessment Tool (HAT) that discriminates between hypertonia subtypes. The HAT was administered to 28 children with cerebral palsy (mean age 9 years, range 4-17 years, 61% male). HAT examinations were videotaped; scores were assigned before and after videotape review. Neurological examination provided the gold standard dia...

it has been reported previously that modulatory effects of pleasant and unpleasant slides on the human acoustic reflex are observed only if startle probes are presented to the left ear or with binaural presentation. the present study examined the effects of the left and the right ear stimulation on modulated startle reflex (as indexed by eyeblink component, measured at the right eye) employing ...

BACKGROUND AND PURPOSE The pattern of antenatal brain injury varies with gestational age at the time of insult. Deep brain nuclei are often injured at older gestational ages. Having previously shown postnatal hypertonia after preterm fetal rabbit hypoxia-ischemia, the objective of this study was to investigate the causal relationship between the dynamic regional pattern of brain injury on MRI a...

A population of reticulospinal neurons with short latency response to startle-inducing stimuli was identified in the nucleus reticularis pontis caudalis (NRPC) and nucleus gigantocellularis (NRGC) of the medial pontomedullary reticular formation. The threshold and magnitude of response to auditory stimuli was correlated in these cells and in the muscles mediating startle. Startle-related neuron...
