Why Equinus Is The Root Of All Foot Evils
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
