Imaging the Proangiogenic Effects of Cardiovascular Drugs in a Diabetic Model of Limb Ischemia

Table 1

Table of assessment criteria for limb damage and limb function after induction of hind limb ischemia.

Score	Limb damage	Functional use
1	No necrosis	Normal foot use for climbing and walking
2	Necrosis affecting one toenail	Reduced ability to grip when climbing/normal use when walking
3	Necrosis affecting two toenails or more	Foot not used for support when climbing/reduced use when walking
4	Necrosis affecting one toe	Foot not used for support when walking
5	Necrosis affecting two toes or more	Dragging limb

Impairment score was determined by multiplying the limb damage score by the functional use score (impairment score = limb damage score × functional use score).
