What evidence do I need to establish service connection for Group XI.Propulsion, plantar flexion of foot (1); stabilization of arch (2, 3); flexion of toes (4, 5); Flexion of knee (6).(1) Triceps surae (gastrocnemius and soleus); (2) tibialis posterior; (3) peroneus longus; (4) peroneus brevis; (5) flexor hallucis longus; (6) flexor digitorum longus; (7) popliteus; (8) plantaris Function: Posterior and lateral crural muscles, and muscles of the calf?

Service connection for Group XI.Propulsion, plantar flexion of foot (1); stabilization of arch (2, 3); flexion of toes (4, 5); Flexion of knee (6).(1) Triceps surae (gastrocnemius and soleus); (2) tibialis posterior; (3) peroneus longus; (4) peroneus brevis; (5) flexor hallucis longus; (6) flexor digitorum longus; (7) popliteus; (8) plantaris Function: Posterior and lateral crural muscles, and muscles of the calf requires three elements: (1) a current diagnosis of the condition, (2) an in-service event, injury, or disease that may have caused or aggravated it, and (3) a medical nexus connecting the current diagnosis to that in-service event. A nexus letter from a treating physician or independent medical examiner is the most reliable nexus evidence. C&P exam findings can also establish nexus if adequately documented.
