Table 1:

Functional scoring for the assessment of hindlimb use during chronic ischemia

Score	Hindlimb Use
4	Dragging of ischemic foot
3	No dragging of ischemic foot but no plantar flexion
2	Plantar flexion but no flexing of toes
1	Normal use of ischemic limb with flexing of toes to resist gentle traction on the tail
