Children with autism often exhibit flopping behavior, which can be characterized by sudden and uncontrolled movements, particularly when they are overwhelmed or overstimulated. This behavior can be a coping mechanism for children with autism to deal with sensory overload or anxiety. Understanding the triggers for flopping behavior can help caregivers and educators provide appropriate support and intervention strategies.
Walking delays in children can be caused by a variety of factors, including physical limitations, developmental delays, or neurological conditions. It is important to assess walking delays in children early on to determine the underlying cause and provide appropriate interventions. Physical therapy, occupational therapy, and other interventions can help children with walking delays improve their mobility and independence.
What is Flopping Behavior?
Behavior known as flopping, commonly seen in children with Autism Spectrum Disorder (ASD), involves sudden dropping or collapsing to the floor without an obvious cause. Effective management of this behavior requires recognizing its features and utilizing suitable strategies. This article aims to define flopping behavior, describe its key characteristics, and offer general strategies for handling and addressing it.
Key Characteristics of Flopping Behavior
Flopping behavior, observed in children with ASD, entails abrupt and uncontrolled dropping to the floor without prior warning. Verbal cues or redirection efforts may not affect children engaging in this behavior. The duration of flopping can vary, ranging from brief moments to an extended period.
Common Characteristics of Flopping Behavior:
- Sudden and uncontrolled dropping: Children may collapse onto the floor unexpectedly.
- Non-responsive to prompts: Verbal cues or attempts to redirect the behavior may not yield responses.
- Variable duration: Flopping can persist for a short time or an extended period.
Visualizing Flopping Behavior
Imagine a child with ASD overwhelmed by sensory input in a busy shopping mall suddenly dropping to the floor and remaining there to grasp how flopping behavior manifests.
Strategies for Managing Flopping Behavior
To address flopping behavior, it is essential to identify triggers, establish break areas, implement visual schedules, teach functional communication, utilize social stories, and apply positive reinforcement techniques. Each child with ASD is unique, necessitating customized strategies to effectively manage flopping behavior.

When Should Children Start Walking?
According to the Australian Early Years National Framework, children should typically achieve walking, climbing, and running milestones between ages 1 and 2. If delays in walking are noticeable, particularly after 18 months, consider an assessment to rule out underlying issues such as neurological problems or muscle weaknesses.
Causes of Delayed Walking
Several factors can contribute to delayed walking, including neurological disorders, muscular dystrophy, hypothyroidism, rickets, learning disabilities, familial history, and prematurity. Physical, mental, and health-related aspects may influence walking delays.
- High muscle tone, balance, or stiffness
When to Seek Assessment for Walking Delays

If your child is happy and developing typically but has not commenced walking by 18 months, there might be no immediate reason for concern. Some children initiate walking later, around the age of 2, similar to delayed speech. However, if other developmental milestones are delayed, including lack of interest in pulling up or cruising furniture by 12-18 months or no walking by age 2, an assessment is recommended.
Addressing Delayed Walking
Ignoring delayed walking issues risks overlooking underlying problems like hypotonia or learning difficulties. Early intervention through physical therapy is crucial to prevent further delays, especially during the critical social years of childhood. Prompt action can help avoid setbacks in a child’s development.
If you have concerns, seek an assessment to eliminate serious issues or take timely action if necessary.
Treatment Approaches for Walking Delays

The treatment plan for walking delays is determined by the underlying causes. In cases where other milestones are achieved, a ‘wait and see’ strategy may be advised. Encouraging activities like tummy time and facilitating opportunities for walking can enhance core muscle strength, preparing for crawling and walking. Practicing standing and walking aids in strengthening muscles and improving balance.
Podiatrists’ Role in Addressing Walking Delays
Podiatrists can provide foot and leg care for children to tackle issues like toe walking, foot abnormalities, and growing pains. For walking delays, a comprehensive assessment is conducted to identify foot structure abnormalities or muscle weaknesses. Treatment options may involve physical therapy, braces, or referrals to other healthcare professionals.
Can autistic children experience delayed walking?
Delay in walking, among other motor skills, is common in some autistic children but not exclusive to autism. Research indicates that motor challenges are more prevalent in autistic individuals, impacting coordination, balance, and overall movement skills.
Can podiatrists assist with delayed walking issues?
Podiatrists play a vital role in managing walking delays, referring individuals to other specialists as required for comprehensive care.
Autistic children may encounter unique movement difficulties, such as coordination issues during walking or running. Delays in fine and gross motor skills can affect activities like tying shoelaces, writing, or playing with balls. Participation in physical education and sports activities can highlight motor challenges in autistic children.
Mental Planning and Coordination of Movement
Apraxia, involving issues with movement conceptualization and planning, can impact coordination in some autistic children. Challenges with mental preparation and proprioception may lead to difficulties in balance, posture, and spatial awareness. Discrepancies between thought and action due to problems with mental preparation and coordination can affect daily activities and motor skills like climbing or balancing.
Improving motor skills through various activities can enhance coordination and balance in autistic children, despite facing challenges in certain movement areas.
Some autistic children may exhibit signs of ataxia, characterized by less organized coordination and abnormal movement patterns. This can influence various movements like walking, running, climbing stairs, jumping, and target touch.
Lax joints, possibly associated with Ehlers-Danlos syndromes, can present as a movement disorder linked to autism, affecting writing skills and necessitating evaluation by therapists.
Handwriting Challenges
Handwriting concerns in autistic children, such as macrographia, are often noted by teachers and parents. Addressing skills through exercises or modifications can be beneficial, with typing skills potentially more valuable in today’s digital age than traditional handwriting.
Excellence in Movement Abilities
Despite movement hurdles, autistic individuals can excel in specific sports like surfing, golf, trampolining, and horse riding. Some may even achieve national or international recognition in championships. Endurance sports like marathon running and activities with predefined movements can be advantageous.
