Biomechanics; Core stability/pelvis/hips, ribs; Foot Injuries; Podiatry. The active subsystem is divided into the ‘global mover’ muscles and the ‘local stabilizer’ muscles which act together to produce the forces needed to create movement. 2015; 49(5):290 (ISSN: 1473-0480) McKeon PO; Hertel J; Bramble D; Davis I. Foot is the most important anatomical part of the body to balance the weight and transmit weight of the body to the ground. Custom foot orthotics are commonly used to control abnormal foot mechanics, aid with injury recovery and provide relief from painful foot pathologies. The foot core system has three subsystems that inter-work to support the foot: 1. This article discusses the function of the intrinsic foot muscles, their contributions to dynamic foot control, and a progressive training paradigm. Intrinsic foot muscles play a crucial role in supporting the medial longitudinal arch, providing the foot stability and flexibility for shock absorption. 2. The passive subsystem consists of the bones, ligaments and plantar fascia in the foot and is responsible for giving the foot it’s shape and providing attachment points for the muscles. No recommendations regarding strengthening! As such, these muscles are seldom addressed in rehabilitation programmes. 390 talking about this. Comparison of the Intrinsic Foot Muscle Activities between Therapeutic and Three-Dimensional Foot-Ankle Exercises in Healthy Adults: An Explanatory Study. NLM HHS A majority of the research related to identifying intrinsic risk factors and treating PHP have focused on the passive subsystem using measures such as navicular drop, rear-foot angle, and the Foot Posture Index-6 (FPI-6) ( Van Leeuwen et al., 2016 ).

Together the active, passive, and neural subsystems form the foot core system which allows dynamic foot control. Central to overall foot function is the arch, or instep. Bottom or ventral surface of the foot is also known as sole or bottom of the foot. We draw the parallels between the small muscles of the trunk region that make up the lumbopelvic core and the intrinsic foot muscles, introducing the concept of the foot core. Passive subsystem of the foot core Dysfunction of these may lead to an increased demand on the remaining components within the foot core system to maintain dynamic foot control, leading to a more rapid breakdown of these contributors and those proximal to the foot. 2015; 49:290. It is reported that the movement of these muscles not only stabilizes the foot while the muscles in the leg (global movers) contract to produce foot movement, but also that they provide valuable sensory feedback by way of the sensory receptors in the neural subsystem. Prince b M.C. Feasibility of the Archercise biofeedback device to strengthen foot musculature. Sci Rep. 2020 Sep 17;10(1):14643. doi: 10.1038/s41598-020-71247-9.
