Posterior Tibial dysfunction is associated with the loss of function of the Posterior Tibial Muscle resulting from a repetitive strain or overuse of this muscle. The Posterior tibial muscle is the main muscle which supports the arch of the foot.

Main contributing factors 
  • Repetitive activity or motion that causes strain on the muscle and tendon
  • Direct Trauma 
  • Poor foot structure causing excessive midfoot collapse
  • Tight calf muscles
  • Inflammatory processes such as Rheumatoid Arthritis
  • More prevalent in Females over the age of 40 years
  • Sudden increase in activity level
  • Increased BMI
Symptoms
  • Diffuse swelling on the arch of the foot
  • Tenderness and warmth on the medial side of the ankle along the course of the tendon
  • A gradual loss of the arch of the foot
  • Excessive heel wear on the medial side of the shoes
  • gait can become unsteady
  • Difficulty rising onto the toes
Treatment for Posterior Tibial Tendon Dysfunction
  • RICE – rest, ice, compression & elevation
  • Non-steroidal anti-inflammatory drugs  (Nurofen etc)
  • Strapping 
  • Activity modification or reduction
  • Footwear modification
  • Orthotic therapy for long term repositioning of the foot.
  • Possible immobilization in casts or walking boots
  • Muscle strengthening exercises
What can you do?
  • Reduce or modify current activities
  • Gradually resume normal activity as symptoms resolve
  • Ice after training/ activity 15 minutes on, 2 hours off, 15 minutes on
  • Footwear assessment – it may be time for a new pair
  • Eccentric strengthening of the posterior tibial muscle.
