Supporting Gross Motor Skill Deficits in Autism
Understanding Gross Motor Skills
Before diving into the specifics of gross motor skill deficits in autism, it's important to understand what gross motor skills are and why they're crucial in a child's development.
Definition and Importance
Gross motor skills involve the large muscle groups of the arms, legs, and trunk. These skills are essential for mobility, independence, and overall health. They allow a child to move and navigate in their environment, participate in physical activities, and perform daily tasks that require strength and coordination. These skills also play a vital role in a child's confidence and self-esteem, as they allow children to engage in the same activities as their peers.
Moreover, gross motor abilities affect a child's endurance to cope with a full day of school, including sitting upright at a desk, moving between classrooms, and carrying a school bag. These skills also impact the ability to navigate the environment, such as walking around classroom items, climbing slopes, or getting on and off a moving escalator. Without adequate gross motor skills, a child may struggle with tasks like eating, packing away toys, or managing toileting activities.
Developmental Milestones
Gross motor skills typically begin developing in infancy and continue to strengthen throughout childhood. Most children pass through specific stages of development at roughly the same time as they grow older. Healthcare providers and parents monitor these improvements with developmental milestones [1].
For example, by the age of 6, most children can skip, a movement that requires a combination of muscle strength, balance, coordination, and timing. The development of gross motor skills becomes more complex over time, and children learn to perform more intricate tasks as they grow older.
The table below provides a rough guide of the gross motor milestones:
It's important to note that while these milestones provide a guide, there is a wide range of normal development. Some children may achieve certain milestones earlier or later than the average. If you have any concerns about your child's gross motor development, it's always best to seek advice from a healthcare professional.
Impact of Gross Motor Skills in Daily Life
In the realm of daily life, gross motor skills play an integral role, influencing everything from school performance to routine activities. For children with autism, the impact of gross motor skill deficits can be particularly significant.
School Performance
Gross motor abilities directly affect a child's endurance to cope with a full day of school. These skills are necessary for sitting upright at a desk, moving between classrooms, and carrying a school bag. Without adequate gross motor skills, a child may struggle with tasks such as eating, packing away toys, or managing toileting activities [2].
Additionally, motor difficulties in autism can have cascading effects on cognitive, social, and emotional development. Poor motor skills may limit interactions with caregivers, hamper social development, and affect academic performance. These challenges can also impact visual-motor integration skills necessary for imitating and learning from others and participating in social interactions [3].
Daily Activities
On a broader level, gross motor skills are essential for everyday functions. These include walking, running, and playground activities like climbing. They are also crucial for self-care tasks like dressing, getting in and out of a car, or climbing into and out of bed. Such tasks emphasize the importance of these skills in daily life.
Gross motor skill development helps children build strength and confidence in their bodies. It promotes the enjoyment of exercise and physical activity and aids in navigating new environments or playing team sports. Moreover, these skills continue to develop throughout childhood and adolescence, becoming more complex over time. For instance, by the age of 6, most kids can skip, a task that requires a combination of muscle strength, balance, coordination, and timing.
In summary, the impact of gross motor skills extends far beyond physical activity and plays a vital role in a child's overall development and day-to-day functioning. Particularly for children with autism, addressing gross motor skill deficits can substantially enhance their school performance and overall quality of life.
Differences Between Gross and Fine Motor Skills
Understanding the difference between gross and fine motor skills is crucial when addressing motor skill deficits in individuals with autism. This section will define and compare these two types of motor skills and discuss their developmental progression.
Definition and Comparison
Gross motor skills involve the large muscle groups of the arms, legs, and trunk, whereas fine motor skills involve the small muscles of the body, typically thought of as the movements that involve the fingers and the hands.
Both gross and fine motor skills require complex coordination of muscles, bones, and the nervous system. Infants typically develop gross motor skills before fine motor skills.
Developmental Progression
Gross motor skills continue to develop throughout childhood and adolescence, becoming more complex over time. By the age of 6, most kids can skip, requiring a combination of muscle strength, balance, coordination, and timing.
Gross motor skills typically begin in infancy and continue to develop and strengthen throughout childhood, with most children passing through specific changes at roughly the same time as they get older. Healthcare providers and parents monitor these improvements with developmental milestones.
However, research and clinical observations have shown that autistic children often face difficulties with posture, coordination, and motor planning. Studies indicate that autistic children can experience gross and fine motor delays and/or atypical motor patterns, with lower scores in praxis tests compared to typically developing peers [5].
Understanding the distinct differences between gross and fine motor skills, as well as their developmental progression, can help in identifying and addressing gross motor skill deficits in autism.
Gross Motor Skill Development in Children
Gross motor skills are crucial in a child's overall development and play a significant role in daily activities. Understanding the developmental stages and the factors that influence this development is key to supporting children, especially those facing gross motor skill deficits in autism.
Developmental Stages
Gross motor skills typically begin in infancy and continue to develop and strengthen throughout childhood. Most children pass through specific changes at roughly the same time as they get older. Healthcare providers and parents monitor these improvements with developmental milestones.
The development of these skills follows a certain pattern. Babies learn from head to toe, with upper-body muscle control developing before lower-body muscle control. This starts with control in the neck (head control) and trunk (sitting balance) before progressing to shoulders, elbows, wrists, and fingers, and the same progression for the lower body from hips to toes.
Gross motor skill development helps children build strength and confidence in their bodies, enjoy the benefits of exercise and physical activity, and aids in navigating new environments or playing team sports.
Factors Affecting Development
Various factors can influence the development of gross motor skills in children. These may include the child's physical health, environmental influences, and the presence of any developmental disorders.
Gross motor abilities affect a child's endurance to cope with a full day of school, including sitting upright at a desk, moving between classrooms, and carrying a school bag. These skills also impact the ability to navigate the environment, such as walking around classroom items, climbing slopes, or getting on and off a moving escalator. Without adequate gross motor skills, a child may struggle with tasks like eating, packing away toys, or managing toileting activities [2].
In children with autism, deficits in gross motor skills can lead to challenges in performing these activities. Understanding these developmental stages and the factors that can affect them is crucial in planning interventions to support the gross motor skill development in children, particularly those with autism.
Gross Motor Skill Deficits in Autism
Understanding the challenges and characteristics associated with autism spectrum disorder (ASD) can help caregivers and educators better support those affected. One area of focus is gross motor skills, which can be significantly impaired in individuals with ASD.
Characteristics and Challenges
Autism manifests in various ways, and the impact on gross motor skills can differ from person to person. However, several common characteristics have been observed.
Individuals with ASD often exhibit impairments in gross motor skills compared to neurotypical controls. This deficit is most pronounced in object control skills, clinical assessment measures, and movements of the upper extremities or the whole body.
Specific gross motor skills associated with ASD include later achievement of early gross motor milestones, atypical gait, fragmented and less accurate reaching skills, poor balance and postural instability, difficulty with ball skills and object control, impaired coordination, and poorer overall gross motor skills.
Motor Impairment in ASD
Motor impairments in ASD, particularly gross motor skills, are tied to the core symptoms of ASD. There is a significant correlation between gross motor and social skills in ASD. This suggests that addressing gross motor skill deficits can potentially improve social interaction in individuals with ASD.
These gross motor deficits in ASD are observable early on. As early as 7 months of age, infants at high familial risk for ASD show signs of these deficits. Moreover, gross motor skills have been found to predict later social and communicative skills for autistic infants and school-age children.
Research and clinical observations have shown that autistic children often face difficulties with posture, coordination, and motor planning. Studies indicate that autistic children can experience both gross and fine motor delays or atypical motor patterns, with lower scores in praxis tests compared to typically developing peers [5].
Understanding these characteristics and challenges can help parents, caregivers, educators, and therapists develop effective strategies and interventions to support the development of gross motor skills in children with autism. With appropriate support and interventions, it is possible to improve these skills and, by extension, enhance their quality of life.
Interventions for Improving Gross Motor Skills in Autistic Children
Addressing gross motor skill deficits in autism is crucial for enhancing mobility, independence, and health outcomes in children diagnosed with this condition. Interventions typically involve physical therapy approaches designed to strengthen key locomotor and object-control skills.
Physical Therapy Approaches
Fundamental motor skills (FMS) interventions play a significant role in addressing motor impairments in autistic children. These interventions involve teaching and strengthening locomotor and object-control skills, such as balance, running, throwing, jumping, and catching. The duration and intensity of these interventions vary, but most involve 1-3 hours per week for a total duration of 6-12 weeks.
Physical therapy typically focuses on the aspects of motor control most affected in autism, such as object control skills and movements of the upper extremities or the whole body. Therapists use structured activities and exercises to improve these skills, helping autistic children gain better control over their bodies and perform daily tasks more easily.
Benefits and Outcomes
Recent studies have shown promising results from FMS interventions in autistic children, including significant improvements in various motor skills, such as fine motor skills, gross motor skills, locomotor activity, and body coordination. Notably, these improvements appear to endure, as shown by follow-up assessments after the interventions.
Not only do these interventions help improve gross motor skills, but they also have a positive impact on social skills. While the correlation between gross motor and social skills in autism is modest (r = 0.27), it is nonetheless significant. This suggests that improving motor skills in autistic children may have far-reaching effects, enhancing their ability to interact with others and navigate social situations.
While the current research is encouraging, more studies are needed to explore the long-term effects of these interventions and to optimize their design. Nevertheless, it is clear that addressing gross motor skill deficits in autism can have a profound impact on the lives of affected children, improving their physical abilities, boosting their confidence, and potentially enhancing their social skills.
