The condition known as ‘fallen arches’ is also referred to as flat feet or pes planus. It arises when the arch of the foot collapses to the point that the entire sole is flat to the ground. It is commonly seen in young children who have yet to develop the muscles in the sole of their feet. In most cases as a child develops and learns how to walk the finer intrinsic muscles that support the sole of the foot will develop normally and an arch forms. However in a small number of cases these muscles don’t form properly and thus neither does the arch. Fallen arches which are acquired in adulthood may be due to a number of factors.
Most commonly fallen arches in adulthood can arise due to Posterior Tibial Tendon Dysfunction (PTTD). The posterior tibial tendon plays a pivotal role in holding up the arch of the foot, damage to this tendon results in the arch collapsing.
Another cause of acquired flat feet in adulthood may be due to Rheumatoid arthritis as this disease attacks the bone, cartilage and ligaments in the foot causing it to change shape and flatten. Injury to the ligament, fracture and/or dislocation of the bones in the mid foot can all lead to a flat foot deformity.
Adult acquired flat fleet can also arise in people who have diabetes or a neurological condition which limits normal feeling in the foot, the muscles in feet switch off, the tendons and ligaments weaken, and the arch eventually collapses.
Patients often experience pain in the foot with fallen arches, and may experience pain further up the chain in the lower leg, knee, and hip and/or lower back.
Our Chartered Physiotherapists will carry out a detailed biomechanical assessment of your feet and lower limb. Once the causes have been identified a number of treatment methods may be used to help relieve pain and restore function in the feet including the use of custom made orthotics to support the foot and offload the areas which are painful, strengthening exercises for weakened muscles and tendons in the arch, and massage and mobilisation techniques to help mobilise stiff tissue and joints in the foot.
