Foot core training begins with targeting the plantar intrinsic muscles via the short foot exercise, similar to the abdominal drawing in maneuver, for enhancing the capacity and control of the foot core system. As such, these muscles are seldom addressed in rehabilitation programmes. Strengthening the muscles inside the foot may provide a form of internal support, potentially reducing occurrence of injury. The evolutionary development of the arch of the foot was coincident with the greater demands placed on the foot as humans began to run. Overview of attention for article published in British Journal of Sports Medicine, March 2014 ... introducing the concept of the foot core. The foot is a complex structure with many articulations and multiple degrees of freedom that play an important role in static posture and dynamic activities.  |  Ital J Anat Embryol. Individuals with PHP exhibited a more pronated foot posture, thicker plantar fascia, and diminished plantar tactile sensation.  |  Central to overall foot function is the arch, or instep. Br J Sports Med 2015;49:290. 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. 2002 Jun;124(3):281-7. doi: 10.1115/1.1468865.

While foot orthotics are used as a form of passive support, physical therapy is commonly used as a form of active support by improving muscular strength, flexibility and endurance, and to recover from various injuries. This can either be through trauma such as broken bones or sprained ankles, (causing de-conditioning as a result of periods of reduced activity or immobilisation); or through repetitive load over a period of time. Just as the core muscles around the spine are essential to stabilize and protect the spine, the foot intrinsic muscles must do the same for the many bones and joints of the foot. The Foot Core System: Understanding the Function of Your Fabulous Feet The Foot’s Complex Design. The foot is a complex structure with many articulations and multiple degrees of freedom that play an important role in static posture and dynamic activities. Increasing the strength and endurance of these muscles with specific exercises has been shown to increase both the activity and size of the important passive stabilizer muscles. Finally, we call for an increased awareness of the importance of the foot core stability to normal foot and lower extremity function. Our feet are our foundations and subject to repetitive loads during every day activities and exercise, so it’s not surprising they can be subject to injury! 2020 Nov 13;17(22):8406. doi: 10.3390/ijerph17228406.

The evolutionary development of the arch of the foot was coincident with the greater demands placed on the foot as humans began to run. This post is a brief introduction to "The Foot Core', also known as the intrinsic foot muscles. 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 ). (Source: http://bjsm.bmj.com/content/49/5/290). The neural subsystem consists of the sensory receptors embedded in the tissues of both the active and passive subsystems. Through training of the passive stabilizers you can improve the function and interaction of the foot core. The Foot Core Kallie Hannon AT, ATC, CSCS and Cale Chaltron AT, ATC What is the Foot Core System? 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. When the passive movers become fatigued, their ability to provide sensory feedback is reduced and the posture of the foot may be compromised. The interaction of these subsystems is very similar to the lumbopelvic core system. HHS The Foot Core System One of many nice things about human movement research is that you get to work with some truly brilliant people, like Dr. Patrick McKeon who published an article, “ The foot core system: a new paradigm for understanding intrinsic foot muscle function,” in the British Journal of Sports Medicine. With this in mind, foot care professionals commonly work along side physiotherapists to improve factors such as balance, lower limb flexibility and lower limb strength. The foot is very complex and is made up of many bones, joints, ligaments and muscles. Sánchez-Rodríguez R, Valle-Estévez S, Fraile-García PA, Martínez-Nova A, Gómez-Martín B, Escamilla-Martínez E.

In the contracted position (right), note the change in foot length (dashed line) due to the short foot contraction drawing in the foot (arrows) from the relaxed condition (solid black line). The passive system makes 4 distinct arches in the foot: medial and lateral longitudinal arches, with the anterior and posterior transverse arch. ABSTRACT The foot is a complex structure with many articulations and multiple degrees of freedom that play an important role in static posture and dynamic activities. If the foot is more prepared to support the weight of the body and to respond to the various daily activities it undertakes, it seems fairly intuitive that this may result in reduced injury rates and a better environment for injury recovery. The foot is a complex structure with many articulations and multiple degrees of freedom that play an important role in static posture and dynamic activities. The So, the bottom of the foot has four distinct layers of muscles, all with important functions. The movement and stability of the arch is controlled by intrinsic and extrinsic muscles.
