Insults to the central nervous system can lead to severe motor impairments in gait or fine motor skills. To develop therapies for motor dysfunction, animal models which have a disease pathophysiology comparable to the clinical population are used. Smaller animals such as rodents are preferred by scientists due to various reasons, such as high reproduction rate and relatively low costs. https://www.creative-biolabs.com/drug-discovery/therapeutics/rodent-behavioral-tests-for-motor-function.htm
