Neurological deficit scoring

Test	Body symmetry	Gait	Circling behavior	Climbing	Front limb symmetry	Compulsory circling
Score	Mouse allowed to move freely on the elevated open rectangular plain surface for two to five minutes			Mouse placed on the gripping surface with 45° angle for 60 seconds	Mouse suspended by tail for 30 seconds	Mouse suspended by tail with front limbs on bench for 30 seconds
0	normal	normal	not present	normal	not present	not present
1	tilting on one side	stiff, inflexible	predominant one-sided turns	climbs with strain	slight asymmetry	tendency to turn to one side
2	moderate asymmetry	limping	circles to one side not constantly	holds on slope	marked asymmetry	circles to one side
3	prominent asymmetry	trembling	circles to one side constantly	slides down slope, unsuccessful effort to prevent fall	prominent asymmetry	pivots to one side sluggishly
4	extreme asymmetry	does not walk	pivoting, swaying, or no movement	slides down immediately, no effort to prevent fall	slight asymmetry, no body or limb movement	does not advance
