Paralysis of voluntary muscles means loss of contraction due to interruption of one or more motor pathways from the brain to the muscle fibers. Although the word paralysis is often used interchangeably to mean either complete or partial loss of muscle strength, it is preferable to use paralysis or plegia for complete or severe loss of muscle strength, and paresis for partial or slight loss. Motor paralysis results from deficits of the upper motor neurons (corticospinal, corticobulbar, or subcorticospinal). Motor paralysis is often accompanied by an impairment in the facility of movement.

A type of Developmental delay characterized by a delay in acquiring motor skills.

A disorder of muscle unrelated to impairment of innervation or neuromuscular junction.

A lack of strength of the proximal muscles.

Amyotrophy (muscular atrophy) affecting the proximal musculature.

Muscular hypotonia (abnormally low muscle tone) manifesting in the neonatal period.
