Fig. 2: The von Mises strain distribution across the plantar foot.
From: Preserving the first ray or first two rays in forefoot amputation for diabetic foot ulcers
In five phases: heel strike (HS), loading response (LR), middle stance (MS), terminal stance (TS), toe off (TO), the overall strain levels in the 1 ray amputation (RA) and 1-2 RA groups were notably higher than those in other groups.
