Recognizing Early Motor Delays

Recognizing Early Motor Delays

Cerebral palsy symptoms can vary, but often show up as delays in reaching developmental milestones. In babies, these delays are usually the first signs that something may be wrong. The main symptom is slow motor development, such as taking longer to roll over, sit, crawl, smile, or walk. How a child moves is as important as when they reach these milestones. For example, a baby might roll over early but do it stiffly or only use one side of the body, which could be a sign of hemiplegia. Sometimes, reflexes that should disappear in infancy, like the Moro or palmar grasp reflex, last longer than normal. At Liv Hospital, we closely monitor these early signs during check-ups to ensure children receive help as soon as possible.

Muscle Tone Variations

Unusual muscle tone is a key sign of cerebral palsy. These changes in muscle tone cause the physical symptoms seen in people with the condition.

  • Stiffness and Spasticity: The most common symptom is overly stiff muscles. This can cause the legs to cross in a scissor-like movement when picked up. The joints may become rigid and difficult to move.
  • Floppiness and Hypotonia: Conversely, some infants appear overly relaxed or floppy. When held, their head may lag backwards, and they may feel like a “rag doll.” This is often an early sign that later evolves into spasticity.
  • Fluctuating Tone: In dyskinetic forms, muscle tone can change rapidly from loose to tight. This fluctuation makes voluntary movement difficult and unpredictable.

Postural and Movement Abnormalities

Postural and Movement Abnormalities
Cerebral palsy has a significant impact on posture and movement. Because the brain cannot coordinate muscle groups well, certain physical signs appear.

Gait Disturbances

Walking patterns are frequently affected. Children may walk on their toes due to tight calf muscles (equinus gait). Others may exhibit a crouched gait, where the knees are constantly bent due to tight hamstrings. A scissoring gait occurs when the adductor muscles of the inner thigh are tight, causing the legs to pull inward and cross. These gait abnormalities can lead to higher energy expenditure and fatigue.

Fine Motor Skill Deficits

Cerebral palsy also affects fine motor skills, which use the small muscles in the hands and fingers. Children may have trouble picking up objects, using their thumb and forefinger together, or moving toys from one hand to the other. Babies may keep their hands tightly closed, which is called fisting. These problems can make daily tasks like eating, dressing, and writing harder.

Oral-Motor Dysfunction

Oral-Motor Dysfunction

The muscles of the face, mouth, and throat can be affected, leading to a range of oral-motor conditions.

  • Dysphagia: This is difficulty in swallowing. It can lead to choking, aspiration (food entering the lungs), and pneumonia. It also makes it challenging to maintain adequate nutrition.
  • Drooling: Poor control of the oral muscles and difficulty swallowing saliva lead to excessive drooling, which can cause skin irritation and social stigma.
  • Dysarthria: Weakness in the muscles used for speech production results in slurred, slow, or difficult-to-understand speech. Some children may be non-verbal and require alternative communication methods.

Musculoskeletal Deformities

Musculoskeletal Deformities

Over time, the imbalance of muscle forces on the growing skeleton leads to secondary musculoskeletal conditions. Spastic muscles do not grow as fast as bone, creating a tension that can pull bones out of alignment.

  • Hip Dysplasia: The hip joint may not develop properly, leading to subluxation (partial dislocation) or complete dislocation. This can be painful and limit mobility.
  • Scoliosis: Curvature of the spine is common, particularly in those with whole-body involvement. It can affect sitting balance and, in severe cases, compress the lungs.
  • Contractures: Permanent shortening of muscles and tendons creates joint stiffness. Common sites include the ankles, knees, hips, elbows, and wrists.

Sensory and Perceptual Conditions

The brain injury in cerebral palsy can also affect the parts of the brain that handle sensory information.

Visual Impairments

Strabismus, where the eyes do not look in the same direction, is very common. Cortical visual impairment means the eyes are healthy, but the brain cannot interpret the visual signals. Nystagmus, or involuntary eye movements, can also occur.

Hearing Loss

Some causes of the disorder, such as severe jaundice (kernicterus) or certain infections, are strongly linked to hearing loss. This can further complicate communication development.

Sensory Processing Disorder

Many individuals have difficulty processing sensory input. They may be oversensitive to touch, sound, or light, or undersensitive and seek out intense sensory experiences.

Gastrointestinal and Autonomic Issues

Cerebral palsy often affects the autonomic nervous system and the muscles that control digestion.

  • Gastroesophageal Reflux Disease (GERD): Weakness in the valve between the stomach and esophagus allows acid to back up, causing pain and vomiting.
  • Constipation: Reduced mobility, low fluid intake, and abnormal bowel muscle tone contribute to chronic constipation.
  • Urinary Incontinence: Lack of control over the bladder muscles can lead to bedwetting or daytime accidents, requiring careful management.

Cognitive and Behavioral Conditions

Cognitive and behavioral problems are also common in cerebral palsy, even though they are not movement symptoms.

  • Intellectual Disability: The severity varies widely. Some individuals have severe cognitive delays, while others have specific learning disabilities but average or above-average intelligence.
  • Behavioral Challenges: Frustration with communication or physical limitations, along with neurological factors, can lead to behavioral issues. Attention Deficit Hyperactivity Disorder (ADHD) is more common in this population.
  • Sleep Disorders: Many children have trouble falling asleep or staying asleep due to pain, muscle spasms, or difficulty changing position comfortably.

FREQUENTLY ASKED QUESTIONS

Why do the muscles become stiff?

The brain sends incorrect signals to the muscles, keeping them in a constant state of contraction. This overactivity prevents the muscles from relaxing, leading to stiffness.

No, drooling is a physical issue related to poor control of the muscles in the mouth and throat. It does not reflect a person’s intelligence or cognitive ability.

With early and consistent physical therapy, bracing, and monitoring, the severity of bone deformities can be significantly reduced, though not always entirely prevented.

No, not all children have seizures. However, epilepsy is a common associated condition, affecting a significant portion of the population due to the brain injury.

Constipation is caused by a combination of limited physical activity, issues with digestive tract muscle tone, and, sometimes, insufficient fluid or fiber intake.
