This video is part two of our series on massage techniques for foot pain. This time, we explore the abductor hallucis muscle. This tissue is easy to miss when treating foot pain, as we tend to focus on the medial arch - often because the abductor hallucis simply doesn't get a lot of time in the spotlight during anatomy education.
The abductor hallucis is one of the superficial medial plantar muscles of the foot. It anchors proximally to the
medial process of the tuberosity of the
calcaneus, to the flexor retinaculum
of the ankle, to the plantar aponeurosis,
and to the intermuscular septum
shared with the flexor digitorum
brevis. Its tendon joins with that of the
medial head of the flexor hallucis brevis
and is usually said to attach distally to
the medial side of the base of the proximal
phalanx of the great toe.
The abductor hallucis acts as a flexor
and abductor of the proximal phalanx of
the great toe. As such, it plays a key role in foot mechanics and overall stability, particularly when providing propulsive force while walking and running.
The posterior tibial nerve and its two
branches, the medial and lateral plantar
nerves, may become entrapped against
the medial tarsal bones by the abductor
hallucis muscle as the nerves pass deep to
the muscle. These nerves pass deep to
the abductor hallucis just below the medial
malleolus, immediately distal to the
flexor retinaculum of the tarsal tunnel.
Entrapment of the nerves in that area by
the taut bands of trigger points in the abductor hallucis
muscle may be responsible for tarsal tunnel syndrome.
Because of its role in stabilising and propelling the foot, the abductor hallucis can be at risk of strain and eventually dysfunction from activity that requires repetitive impact on the feet. The obvious culprits are running and jumping sports, but don't discount dancing, cycling, and even martial arts as contributors. Proper warm-up, stretching, strengthening exercises, and appropriate footwear can help mitigate the risk of injury and muscle imbalance in these activities.
Its trigger points mainly refer to the medial heel with light spillover to the medial arch.
