SCORE	DESCRIPTOR
0 =	No movements of the forelimb (shoulder, elbow, or wrist joints)
1 =	Slight movements of one or two joints of the forelimb
2 =	Extensive movement of one joint and slight or no movement of another joint of the forelimb
3 =	Slight movements of all three joints of the forelimb
4 =	Extensive movement of one joint and slight movement of two joints of the forelimb
5 =	Extensive movement of two joints and slight movement of one or no joints of the forelimb
6 =	Extensive movement of all three joints of the forelimb
7 =	Dorsal or Plantar placement of the forelimb with no or partial weight support in that limb during stance
Weight support is seen when the body is elevated above the surface and there is muscle tension visible in the elbow and/or the shoulder. By definition, there is no stepping without weight support present in that limb. Plantar stepping is considered to be Occasional if 1–50% of the steps are plantar, Frequent if 51–99% of the steps are plantar, and Continuous if 100% of the steps are plantar.
8 =	Dorsal stepping only
9 =	Dorsal stepping with occasional plantar stepping
10 =	Frequent plantar stepping with occasional dorsal stepping
11 =	Continuous plantar stepping with poor wrist control indicated by a mix of rotated and parallel paw position (either at initial contact, lift off, or both) and no toe clearance
12 =	Continuous plantar stepping with paw position predominantly rotated (either at initial contact, lift off, or both) and no toe clearance
13 =	Continuous plantar stepping with paw position predominantly parallel (either at initial contact, lift off, or both) and no toe clearance
14 =	Continuous plantar stepping with paw position predominantly rotated (either at initial contact, lift off, or both) and occasional or frequent toe clearance
15 =	Continuous plantar stepping with paw position predominantly parallel (either at initial contact, lift off, or both) and occasional toe clearance
16 =	Continuous plantar stepping with paw position predominantly parallel (either at initial contact, lift off, or both) and frequent toe clearance
17 =	Continuous plantar stepping with paw position predominantly parallel (either at initial contact, lift off, or both) and continuous toe clearance
