Toe walking is similar to tiptoeing. It’s where a person walks on their toes or the balls of their feet without their heels touching the ground. In adults, tiptoeing is normal and represents an effort to walk quietly, whereas in children it may be abnormal. Most of the time, it is normal. So, for example, it’s normal in some toddlers. It occurs in about one in every 200 toddlers and usually disappears by the time they are three. Sometimes it becomes a habit and persists past three. This requires evaluation.
Most toe walking in children over the age of three is called idiopathic. Idiopathic is the term doctors use when there is no orthopaedic or neurological cause and we don’t know why it is happening. It makes us doctors appear intelligent. Eighty or 90 per cent of the time, idiopathic toe walking disappears spontaneously by age 10.
Idiopathic toe walking runs in families, so it’s a familial tendency to walk on the toes. Sometimes it’s due to the fact that these families have shortened Achilles tendons, the tendon that raises the heel off the ground, so they have a problem putting their feet flat on the ground.
Toe walking can become a habit and persist, to some degree, into adulthood. The other long-term effect, if the heel seldom makes contact with the ground over a long period, is that the calf muscles tighten and you have permanently shortened Achilles tendons.
What to do? Usually nothing major. All toddlers who toe walk should have a more detailed developmental assessment than the one they should be having at every visit to the doctor or Health Centre, and provided this is normal, everyone relaxes. You can certainly try to urge the child not to toe walk, but that seldom happens spontaneously before three, when the toe walking mysteriously disappears. Of course, if you or the physiotherapist have been trying to do tendon-lengthening exercises, you will conclude that your efforts have paid off. But, as happens with most minor child problems, the ageing process solves most of them. Anyway, it’s always nice for you or the therapist to believe that you have “saved” the child. It’s not always nice for your bank account.
The alarming thing about toe walking is that it is associated with two not very nice conditions, cerebral palsy (CP) and autism spectrum disorder (ASD). CP occurs when there is damage to the part of the brain that controls the muscles. This usually happens during pregnancy or birth. It often results in spasticity or increased muscle tone, leading to a shortened Achilles tendon and toe walking. The child cannot physically flatten their heels to the ground when standing. Unilateral toe walking is abnormal and can be a sign of CP and may be accompanied by frequent tripping and falling. A child with CP usually has other delays in development, such as speech and finger agility.
Toe walking is much more common in children with ASD and occurs in about one in every 10 cases. Since ASD became popular among teachers, this is what brings most children with toe walking to the doctor’s attention these days.
It’s important to realise that most children with ASD do not toe walk, and toe walking is not characteristic of children with ASD or any other sensory processing difficulty. Some autistic children, however, do use toe walking as a form of stimming (self-stimulation) to gain extra feedback about their bodies or calm their nervous systems.
There are some other causes of toe walking, and it’s good to know about them. Children with pain in their heel walk on their toes to relieve the discomfort. Heel pain can occur when the heel becomes irritated from sports, running, rapid growth and even injury.
Another cause is flat feet or fallen arches. This can cause heel pain and is part of the examination of any child with heel pain or toe walking.
Most toe walking is therefore harmless and resolves spontaneously. Occasionally, there is an underlying problem, so toe walking should not be dismissed. It may need evaluation by a paediatrician and neurologist and sometimes an orthopaedic surgeon. But most of the time, there is no real difficulty in functioning. Since it is not a major problem and most of the time it resolves spontaneously, little research has been done on it, and this explains the paucity of information for parents, but it always needs to be evaluated.
