However, in patients with unilateral upper limb onset, a different frequency of onset between the right and left sides has been reported. The Awaji criteria allow the diagnosis of ALS to be made earlier and in more patients due to the evaluation of fasciculations. (ALS) accelerates age at onset of ALS onset ALS group and the typical lower limb-onset ALS group. Dysfunction of the upper motor neuron Flail arm syndrome (FAS), a variant of amyotrophic lateral sclerosis (ALS), has many similarities with upper limb onset ALS (UL-ALS). Then, several weeks to months later, weakness develops in another limb. For upper limb-onset patients, there was concordance for side of onset and handedness (64%; p<0. The data support the contiguous anatomical propagation of lower motor neuron involvement in sporadic ALS.
