The tibialis posterior muscle plays a critical role in stabilizing the ankle joint and medial arch, especially during activities like running, walking, and jumping. Unfortunately, this muscle and its associated tendon are prone to injury, particularly in runners. Left untreated, tibialis posterior dysfunction can lead to persistent pain and even contribute to issues in other areas, such as the lower back and hips, due to referral pain patterns.
Recognizing Tibialis Posterior Dysfunction
If you’re experiencing pain on the inside of your shin or behind the ankle bone, you may be dealing with tibialis posterior dysfunction. Symptoms often include:
- An aching sensation at rest or a sharp, burning pain during activity, such as walking, running, or jumping.
- Pain and swelling on the inner side of the ankle, foot, or up to the calf and shin.
- Difficulty standing on tiptoes or climbing stairs.
- Flattening of the arch of the foot or a noticeable limp while walking or running.
Referral pain from this condition may also radiate to the lower back or hips, as the body compensates for the dysfunction, causing imbalances in gait and posture.
Understanding the Tibialis Posterior Muscle
The tibialis posterior muscle originates near the knee joint, runs down the back of the lower leg, and attaches to the bottom of the foot. Its primary functions include:
- Plantar flexion (pointing the toes downward) and inversion (turning the sole inward).
- Supporting the medial arch of the foot during weight-bearing activities.
- Assisting other muscles in lifting the heel during walking and running.
When the tibialis posterior muscle or tendon is overstressed due to weakness, overuse, or improper biomechanics, it can lead to tendinopathy or strain.
Common Causes of Tibialis Posterior Tendinopathy in Runners
Several factors can contribute to tibialis posterior dysfunction, including:
- Overtraining or sudden increases in running mileage.
- Improper footwear that fails to support the medial arch.
- Muscle imbalances or weaknesses in the lower leg and foot.
- Poor biomechanics, such as overpronation or a collapsed arch.
Diagnosing Tibialis Posterior Dysfunction
To confirm tibialis posterior dysfunction, consider these simple at-home assessments:
- Manual Muscle Test: Apply resistance to the foot while attempting to invert it. Pain or weakness can indicate dysfunction.
- Calf Raises: Perform double-leg and single-leg calf raises. Pain or a lack of heel inversion (the heel moving toward the midline) at the top of the movement suggests an issue with the tibialis posterior.
- Endurance Test: Hold a resisted inversion position using a band or side-lying setup for 20–30 seconds. Fatigue or difficulty maintaining the position may signal dysfunction.
Treatment Options for Tibialis Posterior Tendinopathy
At FRWD Sports Therapy, we take a comprehensive approach to treating tibialis posterior dysfunction. Initial steps often include:
- Myofascial Release: To alleviate tension in the tibialis posterior and surrounding tissues.
- Isometric Exercises: Gentle, static holds to build initial strength without overloading the tendon.
- Concentric Strengthening: Progressively loaded exercises, such as band-resisted raises or ball raises, to restore full function.
Advanced Therapies for Pain Relief and Recovery
If your symptoms persist despite at-home exercises, professional care can help. Our treatment options include:
- Dry Needling: To release tight muscles and reduce pain.
- Manual Therapy: Hands-on techniques to improve mobility and tissue health.
- Custom Strengthening Plans: Tailored exercises to restore optimal function and prevent future injuries.
Additionally, addressing referral pain from the lower back or hips is crucial. Dysfunction in the tibialis posterior can cause compensatory patterns that strain other areas of the body. Through stability training, adjustments, and targeted therapy, we ensure the entire kinetic chain is functioning properly.

FAQs
Q: Can tibialis posterior dysfunction cause pain in other areas, like the hips or lower back?
A: Yes, compensatory patterns from this condition can lead to pain in the hips or lower back due to altered biomechanics during walking or running.
Q: How long does recovery take?
A: Recovery varies depending on the severity, but with proper treatment and strengthening, most cases improve within 6–12 weeks.
Q: Do I need orthotics for this condition?
A: Orthotics can help support the arch and reduce stress on the tibialis posterior. Consult your therapist to determine if they’re necessary for your case.
