Fasciculation = MND

What do fasciculations mean in PACES station? One of the prominent lecturer from my university once said, it is equivalent to anterior horn cell lesion until proven otherwise in PACES (or even in clinical practice)!

In the above movie, the patient has fasciculations (spontaneous contraction of a motor unit) noted in the deltoid muscle as well as atrophy. There is also atrophy of the small muscles of the hands. These findings can be seen in motor neuron disease such as amyotrophic lateral sclerosis.
