The disposition to develop an allergic or pseudoallergic reaction, the reaction itself or its consequences. [from SNOMEDCT_US]

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. [from HPO]

An allergy is an immune response or reaction to substances that are usually not harmful. [from HPO]

preferential use of the hand of one side in voluntary motor acts. [from CRISP]
