Muscles of the Foot and Ankle
talocrural subtalar midtarsal joints
Talocrural/Subtalar/Midtarsal Joints

Function:

  • Shock absorption
  • Absorb lower extremity rotatory forces
  • Provide lever for effective propulsion
pronation supination
Pronation/Supination

Pronation

Movement in the direction of eversion, abduction and dorsiflexion.

Supination

Movement toward inversion, adduction, and plantar flexion.

slide12
Talocrural – Pronates (dorsiflexion most dominant with eversion and abduction)

–Supinates (dominated most by plantar flexion with inversion and adduction)

Subtalar – Closed chain pronation (calcaneus everts, talus adducts and flexes)

– Closed chain supination (calcaneus inverts, talus adducts and dorsiflexes)

midtarsal joint mtj
Midtarsal Joint (MTJ)

Subtalar pronation – Promotes mobility in MTJ

and forefoot.

Subtalar supination – Promotes stability in MTJ and forefoot.

Depends on subtalar joint biomechanics

alignment
Alignment
  • Must be assessed from subtalar neutral position (neither pronated nor supinated).
  • Subtalar joint assessed in both prone and weight-bearing positions.
  • Forefoot and rearfoot alignment are evaluated separately.
alignment of tibia foot ankle
Alignment of Tibia, Foot, Ankle

Sagittal Plane

  • Plumbline alignment is slightly anterior to midline through knee and lateral malleolus.
  • Navicular tubercle, line from medial malleolus to where MTP joint of great toe rests on floor.

Frontal Plane

  • Distal one third of tibia is in sagittal plane.
  • Great toe is not deviated toward midline of foot.
  • Toes are not hyperextended.
anatomic impairments
Anatomic Impairments

First ray hypermobility – Dorsal translation with soft endpoint.

Subtalar varus – Inverted twist within body of calcaneus.

Forefoot varus – Inversion deviation of forefoot relative to bisection of posterior calcaneus.

Forefoot valgus – Eversion deviation of forefoot relative to bisection of posterior calcaneus.

examination and evaluation
Examination and Evaluation
  • Patient/client history
  • Balance
  • Joint integrity and mobility
  • Muscle performance
  • Pain
  • Posture
rom and muscle length
ROM and Muscle Length

Examination of knee, hip, ankle, and spine is essential!

  • Hip and knee ROM and muscle length
  • Calcaneal inversion and eversion ROM
  • Midtarsal joint supination and pronation ROM
  • First ray position and mobility
  • Hallux dorsiflexion ROM
  • 1st–5th ray mobility
  • Ankle dorsiflexion and plantar flexion ROM with knee flexed and extended
therapeutic exercise intervention for common physiologic impairments
Therapeutic Exercise Intervention for Common Physiologic Impairments

Balance Impairment

  • Restoration requires positional sense (proprioception).
  • Balance machine, balance board, external perturbation.

Home Exercises

  • Balancing on one leg with eyes open, progress to eyes closed in door frame.
  • Standing on one leg on a pillow or couch cushion with eyes open, progress to eyes closed.
muscle performance
Muscle Performance

Intrinsic Muscles

  • Patient flexes at proximal MTP joint before distal MTP joint.
  • Draw towel under foot, pick up marbles.
  • Using resistant bands to resist proximal MTP joint flexion.

Extrinsic Muscles

  • Resisted talocrural plantar flexion with slow eccentric return to talocrural dorsiflexed position.
  • Closed chain exercises (double leg heel rises, etc.).
slide28
Pain
  • Exercise initiated in pain-free range
  • Soft tissue mobilization
  • Cryotherapy
  • NMES/TENS
  • Exercise for neighboring regions
posture and movement impairment
Posture and Movement Impairment
  • Excessive pronation and supination most common.
  • Exercises developed from components of gait.
  • Goal is to control motions in/out of static positions at varying speeds.
  • Static weight shifting on bathroom scale.
  • Forward/backward stepping.
  • Circular weight-shifting drill.
  • Functional drills (retrowalking, sidestepping, etc.).
rom muscle length joint integrity mobility
ROM, Muscle Length, Joint Integrity, Mobility

Acute Phase

  • Hypermobile segment should be protected (taping, bracing, casting, etc.).
  • Adjacent hypomobile segments should be mobilized with manual therapy or mobility exercise.
  • Dynamic stabilization exercise should be initiated at the hypermobile segment.

ROM, Muscle Length, Joint Integrity, Mobility – Talocrural Joint

Talocrural Dorsiflexion

  • Gastrocnemius and soleus stretching (prevent subtalar pronation).
  • TCJ dorsiflexion ROM (soleus stretch with talar joint in neutral or slightly supinated position.
  • Step-down training to facilitate eccentric control of dorsiflexion.
subtalar joint
Subtalar Joint
  • Full active/active-assisted supination can be performed.
  • Pronation mobility active/active-assisted.
  • Progressions involve functional training of new mobility in appropriate phase of gait cycle.

Plantar Faciitis

  • Overuse caused by excessive pronation.

Treatment

  • Decrease pain and inflammation, reduce tissue stress, restore muscle strength.
  • NSAIDs, US, iontophoresis, massage – for pain.
  • Taping, orthoses, modified footwear to reduce tissue stress.
plantar faciitis treatment cont
Plantar Faciitis – Treatment (cont.)

If pronated

  • Mobilize TCJ
  • Stretch gastrocnemius and soleus
  • Strengthen tibialis anterior and extensor digitorum
  • Initiate functional and proprioceptive activities
posterior tibial tendon dysfunction
Posterior Tibial Tendon Dysfunction
  • Usually excessive subtalar joint pronation and results in acquired foot deformity.

Treatment

  • NWB short leg casting may be necessary for 4–6 weeks (patients with partial tears).
  • Medication and modalities for inflammation.
  • Arch strapping to control end-range pronation.
  • Pain-free, low-intensity, high-repetition open kinetic chain plantar flexion.
achilles tendinosis
Achilles Tendinosis
  • Overuse pathology of Achilles tendon.

Treatment

  • Restore TCJ mobility
  • Stretching is essential after TCJ mobility is restored.
  • Strengthening exercises following inflammation recovery.
functional nerve disorders
Functional Nerve Disorders
  • Assessment should include spine and hip involvement.
  • Nerve involvement may resolve with shoe changes, orthotics, alteration of impairments in alignment, mobility, and movement pattern exercises.
  • Affected nerves include:
    • Tibial nerve
    • Peroneal nerve
ligament sprains
Ligament Sprains
  • 70–80% involve anterior talofibular ligament (ATFL), calcaneal fibular ligament (CFL), posterior talofibular ligament (PTFL).
  • Grade III sprains are further classified:

First degree – Complete rupture of ATFL

Second degree – Complete rupture of ATFL and CFL

Third degree – Dislocation in which ATFL, CFL, and PTFL are ruptured

ligament sprains treatment
Ligament Sprains – Treatment
  • Grade I–II, 1st 4 days – R.I.C.E.
  • Severe grade I/II may need crutches in early stage.
  • Open kinetic chain inversion ROM as tolerated.
  • Progress as pain and swelling are controlled and weight-bearing tolerance increases.
  • Grade III rehabilitation is similar to that of I and II.
ankle fractures
Ankle Fractures
  • Supination adduction injury
  • Supination external rotation injury
  • Pronated abduction injury
  • Pronated external rotation injury

Treatment

  • Edema massage, scar mobilization, edema reduction
  • AROM begins mid-range, low intensity/high reps
  • As function normalizes, ROM exercise is generally more tolerable
adjunctive interventions
Adjunctive Interventions
  • Adhesive strapping
  • Wedges and pads
  • Biomechanical foot orthotics
  • Heel and full sole lifts
summary
Summary
  • Three main joints of ankle and foot are TCL, ST, MTL and subdivided into calcaneocuboid and talonavicular.
  • Extrinsic muscles consist of anterior, lateral, posterior groups. Anterior-dorsiflexion, lateral – everters, posterior – plantar flexors.
  • Functions of foot during gait are shock absorption, surface adaptation, and propulsion.
summary cont
Summary (cont.)
  • Foot and ankle exam must be thorough and include relationships of lower joint extremities.
  • Common anatomic impairments include subtalar varus, forefoot varus/valgus.
  • Common physiologic impairments include loss of mobility, force, torque, balance, impaired balance, and posture.
  • Adjunctive agents may be necessary to treat primary or secondary impairments.
