Why Equinus Is The Root Of All Foot Evils

April 08, 2015

Equnius has been associated with 96.5 percent of all biomechanically-related lower extremity pathologies.1 I have compiled a list of lower extremity pathologies (see below) that research has shown to have an equinus component along with the associated references.

Lower extremity orthopedic pathologies related to equinus:

Plantar heel pain/plantar fasciitis1-26

Achilles tendonitis/tendonosis1,27-33

Posterior tibial tendon dysfunction/adult flatfoot deformity2,8,25,26,32,34-42

Muscle strains43

Stress fractures31,44,45

Shin splints/medial tibial stress syndrome31,44,46,47
