Tibialis Posterior Dysfunction (also known as Posterior Tibial Tendon Dysfunction) is a condition in which the tibialis posterior tendon becomes weakened, inflamed, or damaged, affecting its ability to support the arch of the foot. It commonly develops due to overuse, ageing, previous ankle injuries, obesity, or flat feet. As the condition progresses, individuals may experience pain and swelling along the inside of the ankle, a collapsing foot arch, difficulty walking, and increased discomfort during prolonged standing or physical activity. If left untreated, it can lead to progressive flatfoot deformity and reduced mobility.
Physiotherapy is highly effective in managing Tibialis Posterior Dysfunction by reducing pain, improving tendon strength, and restoring normal foot mechanics. Following a detailed assessment, your physiotherapist will create a personalised rehabilitation programme that may include manual therapy, progressive strengthening exercises, stretching, balance and proprioception training, gait retraining, and activity modification. Footwear advice, taping techniques, and custom orthotic recommendations may also be provided to support the arch and reduce tendon strain. Early physiotherapy intervention helps improve function, prevent progression of the condition, and enable a safe return to everyday activities and exercise.
