Table 1. Limbs classified into groups by amplitude of ankle joint movement, against the outcomes healed ulcer (C5), active ulcer (C6) or no ulcer.

Plantar flexion	2	3	4
C6
Dorsiflexion	11	9	1
Plantar flexion	10	10	1
No ulcer
Dorsiflexion	3	5	2
Plantar flexion	1	4	5

^*Amplitude of ankle joint movement, measured using a universal goniometer.
