Pediatric Physical Therapy for Hypertonia
in Lake Zurich, IL
Does your child struggle to bend their joints, change positions smoothly, or move with ease during play and daily routines? These can be early signs of hypertonia, a condition in which muscles remain tighter than usual, making movement feel rigid even at rest.
With early intervention, the pediatric physical therapists at Infinity & Beyond Pediatric Therapy can help your child with hypertonia build smoother, more coordinated movement patterns so they can move with comfort and enhance their quality of life.

What Is Hypertonia?
Hypertonia is a condition in which your child has increased muscle tone, causing their muscles to feel stiff or tight even when they are resting. This tightness can make it harder for your child to move their arms or legs, maintain balance, or reach developmental milestones such as sitting or crawling.
Hypertonia is related to how your child’s nervous system communicates with their muscles. When the brain has difficulty sending clear signals that tell muscles when to relax, rigidity can occur. Hypertonia is more common in children who were born prematurely or who have conditions such as cerebral palsy, though it can also occur without a clear cause.

Signs of Hypertonia in Children
Signs of hypertonia often appear early in childhood and may include:
- Having stiff or rigid arms and legs
- Keeping hands in fists or having difficulty opening them
- Holding muscles tight even when resting
- Having difficulty changing positions
- Rolling, sitting, crawling, or walking later than expected
- Walking or moving with jerky or uneven patterns
- Favoring one side of the body during movement or play
- Struggling with balance during standing or movement
- Having difficulty chewing or swallowing due to tight facial and mouth muscles
- Getting tired quickly during physical activity
How Physical Therapy Helps with Hypertonia
While hypertonia does not typically resolve on its own, early physical therapy can help your child build a strong foundation for mobility, independence, and participation in everyday life.
At Infinity & Beyond Pediatric Therapy, we create individualized, play-based therapy plans that focus on improving range of motion, increasing flexibility, and reducing muscle stiffness so movement feels easier and more natural.
Therapy sessions use engaging, age-appropriate activities that encourage exploration and build strength without overwhelming your child. We also guide parents through simple movement and positioning strategies to use at home, helping support progress between sessions.
