There are only a few intrinsic muscles in the plantar surface of the foot - see image below. In regards to training parameters, since the intrinsic muscles are small, it seems that motor control (quality of movement, control of movement) and endurance are more important than absolute strength (Headlee et al., 2008). Most of the muscles are in the sole. Intrinsic foot muscles have the capacity to control deformation of the longitudinal arch.

You can divide the foot muscles into groups based on their locations — either in the sole of the foot (the bottom or plantar area) or the dorsum on the top of the foot. The muscles mainly customize and improve the actions of the long tendons and help fine movements of the toes. The purpose of the proposed study is to examine the effect training the intrinsic foot muscles on performance in selected physical and functional measures such as balance, plantar pressure during gait, vertical jump, and foot posture. Common foot pain conditions such as arch or heel pain, plantar fasciitis, and metatarsalgia are commonly associated with an over-flexible foot and dropped arch – clinically referred to as over pronation.. The extrinsic muscles arise from the anterior, posterior and lateral compartments of the leg. The intrinsic muscles are positioned within the foot and are liable for the fine motor actions of the foot, for example, movement of individual digits. Dr. Ray notes that the intrinsic foot muscles (aka plantar arch muscles) are a group of muscles that originate at the heel bone and attach to the toes. INTRINSIC MUSCLES OF THE FOOT. The lumbrical muscles arise from the tendon of the flexor digitorum longus.. Insertion. The intrinsic muscles in your foot are a small group of muscles that perform a variety of functions in order to help you maintain balance. So, if a person weighs 60kg, their feet should be able to pull about 6kg in weight. Except for the extensor muscle that is nervous supply by deep fibular nerve, all muscles of the foot have nervous supply by medial and plantar branches of tibial nerve.The deep fibular nerve may also partly supply nerves to the first two dorsal inerrosei. The foot intrinsic muscles are increasingly targeted in foot and ankle rehabilitation. Intrinsic foot muscles have both attachments inside the foot, whereas extrinsic foot muscles have one attachment in the foot and the other attachment up in the leg. They are chiefly liable for actions such as inversion, eversion, plantar flexion, and dorsiflexion of the foot. Description of “Short Foot” exercise for strengthening intrinsic foot muscles: Sit with feet flat on ground, shoulder width apart. Extrinsic muscles have at least one attachment on the leg. The foot is a complex system with multiple degrees of freedom that play an essential role in running or sprinting. The exercises are often difficult to learn initially.

Although many of the actions of the intrinsic muscles (such as toe flexion and extension) are complemented by extrinsic muscles, others, such as active ab/adduction of the digits and maintenance of forefoot integrity and stability, result only or largely from intrinsic muscle action (17–19). Clin Biomech.
