Upper motor neuron diseases are a heterogeneous group of disorders in which a degeneration of motor neurons of the cortex and tronchoencephalic motor nucleus occurs. Clinically, these disorders are characterized
Anupper motor neuron(UMN) lesion is the result of numerous disorders that can impact thecentral nervous system. UMNs make up the corticobulbar/corticospinal/pyramidal system. Although theanatomyof the system is described in greater detail in other entries in this Encyclopedia, briefly stated, the ...
We detail the methods and, as a first proof of concept, relate the results of select children with upper motor neuron lesions (n=48) to reference groups of neurologically intact children (n=62) and adults (n=64). Linear mixed models indicated that the cumulative therapist score, rating the...

Upper Motor Neurones Strokes are a common cause of UMN signs since cranial or brainstem ischaemia affects the function of neurones located in these regions. The clinical signs caused by strokes typically relate to the affected vessel and its respective blood distribution. In particular, UMN signs ...

Ultrastructural alterations of the activating and metabolic machineries, and the presence of fibers with lower motor neuron denervation features, may explain the low-force output and the reduced endurance of paretic muscles. Conclusion: The stable muscle atrophy that characterizes long-lasting spastic ...
