Precise palpation begins with orientation. Before deciding what a tissue feels like, a therapist needs a reasonable idea of where the hand is, what lies beneath it and which neighbouring structures could produce a similar sensation. The foot and ankle make this especially important: prominent bones, closely packed tendons, small muscles and superficial nerves occupy a compact region.

This article expands the JANMI Palpatory Anatomy Lab foot-and-ankle introduction. It is a learning guide for appropriately trained therapists and supervised students, not a diagnosis protocol or a set of instructions for treating an unexplained painful foot.

Begin with the person, then the landmarks

Ask about symptoms, recent injury, surgery, altered sensation and activities that matter to the person. Explain the examination, obtain consent and agree how they will signal discomfort. Support the leg so that the client does not have to hold the foot still. Expose only the area required and maintain appropriate draping.

Start with light contact and broad orientation. A supported position, a different viewing angle or a small comfortable movement may clarify a structure more effectively than additional pressure. Where identification remains uncertain, record the uncertainty. Do not turn an unclear sensation into a confident anatomical claim.

A working map of the foot and ankle

The ankle mortise is formed by the distal tibia and fibula around the talus. The foot includes the hindfoot, midfoot and forefoot. Ankle dorsiflexion and plantarflexion should be distinguished from movements distributed through the subtalar and midfoot joints. What appears to be a single movement of the foot may involve several articulations.

The following landmarks provide reference points. Their prominence varies with individual anatomy, swelling, previous injury and the position of the foot. A landmark is an orientation aid; tenderness over it does not establish a diagnosis.

The malleoli and calcaneus

The medial malleolus is the distal tibial prominence on the inner ankle; the lateral malleolus belongs to the fibula. Establish their outlines gently before approaching the tendons that pass around them. The lateral malleolus normally extends farther distally and lies more posteriorly than the medial one; the two sides are not mirror images.

The calcaneus forms the heel. Its posterior contour helps orient the Achilles attachment, while its plantar surface is covered by a substantial heel pad. Distinguish the outline of bone from the compressibility of the overlying tissues. Painful pressure into the heel is not necessary to establish where the calcaneus is.

Navicular tuberosity and sustentaculum tali

The navicular tuberosity is a prominence on the medial midfoot and an important reference for the tibialis posterior tendon. Its size and contour vary. A prominent medial bump should not automatically be described as a displaced bone or a collapsed arch.

The sustentaculum tali is a medial projection of the calcaneus supporting the talus. It lies below the medial malleolus and is less straightforward to distinguish through living tissues than a diagram suggests. The flexor hallucis longus tendon travels beneath it. Use this relationship to understand the region, not as a reason to press deeply beneath the bony shelf.

Cuboid and base of the fifth metatarsal

The cuboid lies in the lateral midfoot, between the calcaneus and the bases of the fourth and fifth metatarsals. Its boundaries can be difficult to isolate through soft tissue. Surface palpation alone cannot establish that a cuboid is out of position.

The base of the fifth metatarsal offers a more distinct lateral reference. Fibularis brevis attaches to its tuberosity. Focal pain here after an injury requires appropriate assessment rather than forceful local work. Do not confuse a tender bony attachment with a muscle belly.

Anterior region: tibialis anterior

Tibialis anterior runs along the front of the leg, lateral to the tibial crest. Its tendon crosses the anterior ankle towards the medial cuneiform and base of the first metatarsal. It contributes to dorsiflexion and inversion.

In a comfortable supported position, gentle active dorsiflexion with a small inversion component can help a student correlate the visible or palpable tendon with its expected course. Compare the resting and contracting states using light contact. This is an identification aid, not an isolated strength test: other muscles also participate.

Avoid assuming that every cord at the front of the ankle is tibialis anterior. Toe-extensor tendons occupy the same general region. Observe whether the toes move, trace the expected direction and return to a known landmark if the finding is ambiguous.

Posterior region: gastrocnemius, soleus and Achilles tendon

Gastrocnemius is superficial and crosses both knee and ankle. Soleus lies deeper and does not cross the knee. Both contribute to plantarflexion through the Achilles tendon, which attaches to the posterior calcaneus.

Changing knee position changes the length of gastrocnemius and can help organise a teaching comparison. It does not switch gastrocnemius off or isolate soleus perfectly. Support the limb, compare comfortable movement with the knee more extended and more flexed, and describe what changes without assigning all restriction to one muscle.

The Achilles can be followed towards the heel with gentle contact, but squeezing a symptomatic tendon is not a useful demonstration of palpatory precision. A change in thickness, tenderness or texture is a finding to document, not proof of degeneration or a tear. A sudden injury with a snap, marked loss of push-off or difficulty walking warrants medical assessment.

Lateral region: fibularis longus and brevis

Fibularis longus and brevis occupy the lateral leg, and their tendons pass behind the lateral malleolus. Brevis continues to the base of the fifth metatarsal. The longus tendon turns into a groove on the plantar surface of the cuboid, then crosses the sole towards the base of the first metatarsal and the medial cuneiform. Both contribute to eversion and assist plantarflexion.

A small comfortable eversion movement can help orient the tendons. Near the lateral malleolus they lie close together, so a student should not claim to distinguish them solely from a single point of pressure. Follow their expected courses, consider the attachments and use the tutor’s feedback.

The region also contains superficial neural structures, including the sural nerve posterior to the lateral malleolus. Tingling, burning or an electric sensation is a reason to stop and reassess contact, not to increase pressure.

Medial region: tibialis posterior and the long toe flexors

Tibialis posterior lies deep in the posterior leg. Its tendon passes behind the medial malleolus and has a major attachment at the navicular, with further extensions into the foot. It contributes to inversion, plantarflexion and support of the medial arch. Its deep muscle belly cannot be confidently isolated simply by pressing harder into the calf.

Flexor digitorum longus continues towards the distal phalanges of the lesser toes; flexor hallucis longus continues to the distal phalanx of the great toe. Their tendon paths and responses to comfortable toe movement can help teach anatomical relationships. Movement is corroborating information, not proof that the fingertip has isolated one tendon.

Behind the medial malleolus, the tarsal tunnel contains the tibialis posterior, flexor digitorum longus and flexor hallucis longus tendons together with the posterior tibial vessels and tibial nerve. These are close neighbours. This is not a space to explore with sustained deep compression. Pulsation or neural symptoms should prompt withdrawal of pressure and reassessment.

Plantar region: fascia and intrinsic muscles

The plantar fascia is connective tissue beneath the foot, not a muscle. It contributes to the mechanical support of the longitudinal arch and interacts with toe movement. Gentle great-toe extension can make the central band more apparent, but a painful response is not by itself evidence of plantar fasciitis or an adhesion.

Intrinsic foot muscles have their origins and insertions within the foot. The superficial plantar layer includes abductor hallucis medially, flexor digitorum brevis centrally and abductor digiti minimi laterally. Deeper layers include muscles that contribute to toe control and load sharing.

Ask for a small, comfortable toe movement and observe before adding contact. Strong toe curling can recruit the long toe flexors as well as intrinsic muscles; it is not a clean measure of intrinsic function. The central sole also contains fascia, tendons, nerves and vessels. Feeling a firm band does not tell us which tissue is responsible for symptoms.

A repeatable supervised learning sequence

1. Orient: name the side, region and nearest reliable bony landmark before contact. State what you expect to find and what lies nearby.

2. Position: support the client and choose a position that allows comfortable movement without unnecessary guarding. Adjust your own stance so the hand can remain steady.

3. Locate: use light contact to identify an outline or expected tendon course. Change hand angle before considering more pressure.

4. Corroborate: ask for a small relevant movement, observe the response and compare it with the expected anatomy. Avoid painful resistance or repeated symptom provocation.

5. Check: explain your reasoning to the tutor. If the landmark, movement response and tissue direction do not agree, return to orientation rather than defending the first guess.

6. Document: separate the observation from the interpretation. For example: “Tenderness reported near the medial ankle during light contact; structure not confidently isolated.” This is more defensible than declaring that a specific tendon is damaged.

What palpation can—and cannot—tell us

Palpation can help organise surface anatomy, identify tenderness reported by the client and observe how a region responds to position, contact or movement. Findings need to be considered alongside history, function and any relevant assessment.

Touch alone does not reliably establish tissue pathology, nerve entrapment, structural correction or the cause of pain elsewhere in the body. A stiff ankle may be relevant to a person’s movement choices, but it does not prove that the ankle caused their knee, hip or neck symptoms. Compare plausible explanations and reassess meaningful function rather than forcing observations into a fixed causal chain.

Know when not to continue

Stop if contact produces worsening pain, persistent tingling, numbness or other concerning symptoms. New unexplained one-sided calf pain with swelling, warmth or skin colour change needs urgent medical assessment for possible deep vein thrombosis; do not massage the region. For suspected DVT, seek an urgent GP assessment or contact NHS 111. If these symptoms occur with breathlessness or chest pain, call 999; do not drive yourself to A&E.

Recent significant trauma, inability to bear weight, a hot swollen joint, a wound or suspected infection also calls for appropriate clinical assessment. Adapt or defer practical work when sensation, circulation, skin integrity or postoperative precautions make normal feedback unreliable. This is not an exhaustive screening checklist.

What students can take into their next practice session

The immediate aim is a more organised examination: clearer landmarks, better client support, steadier hand contact and more purposeful use of movement. Students should also leave better able to recognise uncertainty, explain findings in plain language and stop when a structure cannot be approached safely.

These are skills to practise and refine. A workshop does not confer a new clinical qualification, expand professional scope or guarantee improved treatment outcomes. At JANMI, demonstration is followed by supervised practice, direct correction and repetition: I demonstrate. You palpate. I correct your hands. You practise again.
