Foot drop (drop foot, pes equinus) is a foot deformity that makes it very difficult for the heel to come into contact with the ground. This causes the patients to walk on the tips of their toes. Many people with pes equinus cannot manage to place their entire foot on the ground and therefore struggle with using their feet properly for walking. In many cases, the Achilles tendon is also shortened, which can affect the functioning of the entire leg.
Distinctions are generally made between neurological or syndromic non-neurological causes.
Neurological or syndromic causes include:
Non-neurological causes include:
The most common – especially in childhood – are neurological and idiopathic pes equinus:
Pes Equinus is most commonly observed in patients with underlying neurological disorders. Such disorders are characterized by impaired connections between the central nervous system (CNS), nerves, and muscles and often result in muscle spasticity. Cerebral Palsy is an example of a CNS disorder that causes spastic paralysis.
Children with idiopathic pes equinus walk on the tips of their toes from the very beginning, but, unlike children with neurogenic pes equinus, they can also stand on their entire foot and walk with a normal gait pattern. However, they seem to prefer walking on their toes.
The cause of idiopathic or habitual toe walking is unknown but underlying neurological diseases are ruled out.
Children often walk on the tips of their toes when learning to walk. However, they usually develop a normal gait pattern over time. If this is not the case, long-term consequential damage such as Achilles tendon contractures, foot disorders or damage to the spine may occur. In light of all this, it is important to treat idiopathic toe walking.
Early treatment is of great importance for both idiopathic and neurogenic pes equinus. Both conservative and surgical measures (occasionally in combination) are possible.
In addition to physiotherapy and Botox injections, orthoses are used relatively frequently to treat toe walking.
There are two main orthotic options for pes equinus:
With our lower leg orthosis with a ring-shaped foot shell, we can offer an exclusive orthopedic device that has shown a high success rate in the treatment of pes equinus. What makes this device so special is that it can be worn during the day and at night, thus combining both objectives – improving the gait and stretching the soft tissues.
Special orthopedic shoes, with their differently shaped soles, can reinforce the positive effects of the orthosis.
If conservative therapy with orthoses does not lead to the desired success, or if further deformities are present, surgical steps may be necessary.
An orthosis is used to stabilize, relieve, immobilize, guide or correct limbs. This prevents or corrects incorrect postures and strains.
When choosing orthopedic shoes, it is important to make sure that the shoe supports the purpose of the orthosis. There are numerous models with different designs.
Despite the large number of therapeutic approaches for idiopathic toe walking, no gold standard approach exists. The study presented here considered the effects of lower leg orthoses with ring-shaped foot shells on children with idiopathic toe walking. The results are promising.
