Secondary conditions caused or aggravated by 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 may be ratable under 38 CFR § 3.310. Veterans should work with a VSO or accredited claims agent to document the medical relationship.

The key evidence 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 depends on the body system. For musculoskeletal conditions, range of motion measurements (active, passive, weight-bearing, and non-weight-bearing per Correia v. McDonald) and documented flare-ups are the most impactful evidence. A nexus letter from a qualified medical professional is essential for contested claims.

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 maxes at 30%, below the single-disability TDIU threshold of 60%. However, combined with other service-connected disabilities totaling 70%+ (with one at 40%+), TDIU under § 4.16(a) may apply. Extraschedular TDIU under § 4.16(b) is available if 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 alone prevents work regardless of the rating percentage.
