(3) showed that autistic children between the ages of 3 and 10 walk somewhat like Parkinsonian adults in that they walk more slowly than normal, with shorter steps.
A pattern of behavioral (such as delayed walking) and genetic features seen in some cases of autism spectrum disorder (ASD) could ultimately lead to identification of subgroups and improved treatment.
About 85 percent of the children in each group walked independently by 18 months. But when researchers focused on children with IQs of around 50, they found that 60 percent of the children with intellectual disability, ADHD or language disorders walked by 18 months compared with 80 percent of those with autism.

Skipping this milestone may not necessarily be a sign but, when taken into consideration with a failure to walk by 18 months, could be indicative of autism.
Children with autism spectrum disorder (ASD) often have developmental delays, meaning they do not to reach all of their social, emotional, communication, cognitive, and physical milestones at the appropriate times. But that statement is a huge oversimplification for several reasons.
Delays meeting certain milestones can also be a sign of autism: 9 months of age: not responding to their name. 9 months of age: not showing facial expressions associated with basic emotions like happy, sad, angry or surprised. 12 months of age: not engaging in simple interactive games like pat-a-cake.
People with autism sometimes may have physical symptoms, including digestive problems such as constipation and sleep problems. Children may have poor coordination of the large muscles used for running and climbing, or the smaller muscles of the hand. About a third of people with autism also have seizures.
Research suggests that toe walking can be a sign of autism, particularly when it's combined with language delays. In general, toe walking is more common in children with ASD and other neuropsychiatric conditions than in the general population.
Children with ASD tend to augment their walking stability with a reduced stride length, increased step width and therefore wider base of support, and increased time in the stance phase. Children with ASD have reduced range of motion at the ankle and knee during gait, with increased hip flexion.
These individuals take longer to take a step or a full stride, and have shorter strides than controls do. This means that they walk more slowly overall.
What age is considered delayed for walking? Delayed walking is generally considered to be when a baby has not taken their first steps by 18 months of age. However, it is important to keep in mind that every baby develops at their own pace and some may take longer to reach this milestone.
Most children are able to walk alone by 11-15 months but the rate of development is very variable. Some children will fall outside the expected range and yet still walk normally in the end. Walking is considered to be delayed if it has not been achieved by 18 months.
Late walking can also be associated with having low muscle tone or hypermobile joints. Other causes include neurological issues affecting muscle tone, inherited conditions affecting muscle strength or bones and hip joints, all of which may be identified earlier than 16 months old.
They have specific repetitive behaviors such as running in circles, lining things in rows, spinning or spot jumping especially when unoccupied, bored, unhappy or upset. They can become rote in routines such as specific seats, routes and schedules. So they may not adapt well to changes in the environment or schedules.
They occur because of the extreme rigidity of thinking associated with Autism and the inability to deal with unexpected events. These refusal episodes can be seen as a “temporary paralysis of will” which will count towards a “virtual inability to walk”.
However, in 2019 a large-scale review of trends and treatment patterns found that 9% of children with ASD are diagnosed with persistent/idiopathic toe walking compared to less than 0.5% of children without an autism diagnosis (Leyden et al., 2019).
Children with ASD often have problems with their feet and ankles. Some of the common problems that podiatrists help with in children with ASD are sensation issues, such as not being able to feel pain in the feet; and alignment issues, such as toe walking (tip-toeing) or flat feet.
autistic children often have difficulties with posture, coordination and motor planning. Research consistently shows that autistic children can experience both gross and fine motor delays and/or atypical motor patterns (e.g. Green et al. 2002).
Early signs of autism include atypical social and communication behaviour, repetitive behaviour or movements, and intense interests. Early signs of autism usually appear in the first 1-2 years of life.
A dysfunctional vestibular system, a common problem in autism, may be responsible for toe walking. The vestibular system provides the brain with feedback regarding body motion and position.
Children with autism have a problem with decreased muscle tone or increased muscle weaknesses. As a result, their body posture falls in the forward direction putting their weight over their toes. This is why they tend to walk on their toes rather than their feet.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Some developmental health professionals refer to PDD-NOS as “subthreshold autism." In other words, it's the diagnosis they use for someone who has some but not all characteristics of autism or who has relatively mild symptoms.
