Normal gait (walking)
A normal gait is called a heel-toe gait and that
means that as one leg swings forward, it lands with the heel
on the ground first. Then the body proceeds over that stance
phase limb and finally the foot raises up on tip-toe right before
it swings forward again. When the leg is on tip-toe, the other
leg is on heel strike so in normal gait there is never a time
when a child should be on both tip toes.
Walking on Tip Toes on one Side
One of the more common reasons is that one leg
is quite short and if the leg is more than about 3 cm short,
a child will often compensate by tip toeing so that the leg
reaches the ground. A child that is spastic in one leg or one
side of the body may tend to tip toe on that side because of
the overactive gastrocnemeus (calf muscle). The patient who
has a severe achilles tendonitis (pain in the back of the calf
muscle) or severs calcaneal apophysitis (heel pain) might tip
toe to take some of the tension off of their achilles tendon.
A rarer cause of a child tip toeing on one side only could be
deep muscular calf hemangioma, this is a vascular neoplasm which
causes swelling of the calf muscle.
Walking on Both Tip Toes
The most cause common is idiopathic toe
walking (no known cause), also called habitual toe walking.
Walking on tiptoes is quite common between 10 and 18
months when children are learning to walk. In some children
it simply becomes a habit, when asked to walk normally they
put their heel down on the ground before their toes. It's just
that when they're not concentrating they seem to revert to walking
on their toes.
Mild spastic diplegic cerebral palsy is also very
common. Then more rarer conditions that can cause children on
walking on both tip toes are Charcot-Marie-Tooth peripheral
neuropathy or muscular dystrophy, such as Duchene. Then, even
some less common things like autism, schizophrenia and finally
spinal cord anomalies and juvenile type multiple sclerosis.
Early onset tip toeing is defined as tip toeing
that occurs within three months of the the child walking. Far
and away the two most common reasons for this are idiopathic
toe walking and spastic diplegic cerebral palsy. Cerebral palsy
refers to a group of conditions that affect control of movement
and posture. Because of damage to one or more parts of the brain
that control movement, an affected child cannot move his or
her muscles normally. While symptoms range from mild to severe,
the condition does not get worse as the child gets older. With
treatment, most children can significantly improve their abilities.
Late onset tip-toe gait is defined as tip toeing
which begins at least about four months after a patient has
had a well-developed normal heel-toe walk. This is virtually
always due to some neuromuscular problem which will require
an examination by a neurologist.
It is also important to note if their was a family
incidence of tip toe walking. One of the most common contributing
factors is a tight achilles tendon. Normally, a child should
have about 10 degrees of ankle dorsiflexion (the amount your
foot can extend towards your body when the foot is not tensed);
however, a child can walk with a normal heel-toe gait as long
as they can get to this neutral (The sub taler joint in the
ankle is neutral when it is neither twisted in nor twisted out.).
Treatment
Most children will need to be referred to a physiotherapist,
orthopedist and neurologist for treatment.
Idiopathic toe walking may be cured by just observing
the condition and hoping that the child might eventually outgrow
their tip toe gait. If you want to control an overactive calf
muscle then the doctors might try to just hold it still with
an ankle-foot orthosis (AFO Brace). If it is being caused by
a tight achilles tendon then surgery may be required. The most
common procedure is a gastrocnemius recession procedure. An
alternative could be casting to correct the achilles tendon.
It can be very difficult to distinguish between
idiopathic toe walking and mild spastic diplegic cerebral palsy.
It seems simple enough, but it really is not because both conditions
are highly associated with premature birth, developmental delay
and tight achilles tendons. However a good sign is if the child
can walk completely normal when you ask them to, it is more
likely that they might have idiopathic toe walking.
For psychiatric toe walking, there is just no
literature about how to treat this. There is very little literature
about it at all. It's seen once in a while in schizophrenic
children, autistic children or children with learning disorders.
There are no relevant treatment option that have been documented
for this.
Spastic diplegic cerebral palsy is again almost
always early onset tip toeing. The family history is negative
and they should have upper motor neuron lesions or dynamic EMG
(Electromyography is a test that assesses the health of the
muscles and the nerves controlling the muscles) that is abnormal.
If their is an over active achilles tendon then you could use
bracing. If a patient's dynamic contracture is so strong that
they are fighting the brace, and then the doctors might try
casting or Botox (Botox is an experimental treatment) to weaken
the muscle and then continue with the brace. If the achilles
is physically tight, then a lengthening procedure would be used
and perhaps a hamstring lengthening also if the patient is crouching
significantly.
Signs of upper motor neuron lesions include weakness,
hyperreflexia (Reaction of the autonomic (involuntary) nervous
system to over-stimulation), and increased tone. Note that with
acute upper motor neuron lesions there is often flaccid paralysis
(weakness or loss of muscle tone resulting from injury or disease
of the nerves innervating the muscles) with decreased tone and
decreased reflexes.
Most children will eventually outgrow
their tip toe gait but if you have any doubts then you should
visit your family doctor as the first point of call.
