Study Notes
Cerebral Palsy
- Cerebral Palsy (CP) is an umbrella term for a group of permanent disorders that affect movement and posture.
- CP results from non-progressive disturbances in the developing fetal or infant brain.
- The Australian Cerebral Palsy Register reports on births between 1993 and 2006.
Cerebral Palsy- Pathophysiology
- Premature neonatal brains are vulnerable to two main pathologies:
- Intraventricular haemorrhage (IVH) - Bleeding into the brain ventricles.
- Increased risk in preterm infants due to underdeveloped periventricular blood vessels.
- Risk of CP increases with IVH severity.
- Periventricular Leukomalacia (PVL) - Brain damage affecting white matter causing cell death and empty spaces.
- Periventricular white matter is involved in controlling motor function.
- Spasticity, cognitive impairments, and vision issues are frequently associated with PVL.
- Approximately 60-100% of babies with PVL will be diagnosed with CP.
- Intraventricular haemorrhage (IVH) - Bleeding into the brain ventricles.
Cerebral Palsy Classification
- Cerebral Palsy is classified based on the type of movement disorder:
-
Spastic Cerebral Palsy: Characterized by hypertonia or increased muscle tone.
- Upper Limbs (Arms & Hands): Flexion at the elbow, wrist, and fingers.
- Lower Limbs (Legs): Flexion at the hip, adduction or scissoring of the thighs, flexion at the knee, equinovarus foot posture.
-
Ataxic Cerebral Palsy: Characterized by uncoordinated movements, unsteady gait, and tremor.
- Individuals with ataxia often experience difficulty with balance due to issues with depth perception.
-
Dyskinetic (Athetoid) Cerebral Palsy: Characterized by difficulty controlling muscle movement, resulting in twisting, abrupt, and repetitive movements.
- Dystonia: Twisting and repetitive movements that can be painful.
- Athetosis: Slow, writhing movements.
- Chorea: Irregular, abrupt movements.
-
Spastic Cerebral Palsy: Characterized by hypertonia or increased muscle tone.
Cerebral Palsy Signs and Symptoms in Babies and Young Children
-
Babies:
- Low muscle tone (feels floppy when picked up)
- Unable to hold up head while lying on stomach or in a supported sitting position
- Muscle spasms or stiffness
- Poor muscle control, reflexes, and posture
- Delayed development (difficulty sitting up or rolling over by 6 months)
- Feeding or swallowing difficulties
- Preference for using one side of the body
-
Young Children:
- Delays in reaching physical milestones:
- Not walking by 12-18 months
- Not speaking simple sentences by 24 months
- Signs of Cerebral Palsy may warrant consultation with an early childhood nurse, general practitioner, or paediatrician.
- NSW families are provided with a Personal Health Record book (Blue Book) containing information about developmental milestones at birth.
- Delays in reaching physical milestones:
Cerebral Palsy Severity Classification
- Cerebral Palsy severity can vary and is classified using three systems:
- Gross Motor Function Classification System (GMFCS): Classifies the level of gross motor function.
- Manual Ability Classification System (MACS): Classifies the level of hand function.
- Communication Function Classification System (CFCS): Classifies the level of communication ability.
Cerebral Palsy Associated Impairments
- Cerebral Palsy is often associated with various impairments including:
- Cognitive Impairments: Learning difficulties, attention-deficit hyperactivity disorder (ADHD), and intellectual disabilities.
- Sensory Impairments: Visual impairments, hearing loss, and problems with touch, taste, smell, and body awareness.
- Seizures: Epilepsy or other seizure disorders.
- Speech and Language Problems: Difficulty with speaking, understanding language, or both.
- Bowel and Bladder Control Problems: Constipation and incontinence.
- Feeding and Swallowing Difficulties: Dysphagia, a condition that makes it difficult to swallow.
- Social and Emotional Challenges: Social isolation, anxiety, and depression.
Clinical Interventions in Physiotherapy
- Clinical interventions in physiotherapy for children with Cerebral Palsy were originally based on the developmental sequence for planning treatment.
- However, it is important to recognize that the child's biological systems are not the sole determinant of motor performance.
- Motor performance is influenced by a dynamic interplay between three factors:
- The child
- The task
- The environment
- Clinical interventions must consider child-rearing practices, family involvement, and the influence of the environment.
Cerebral Palsy Definition
- Cerebral Palsy (CP) is a disorder affecting movement and posture that begins in early childhood due to brain damage.
- The brain damage is permanent but early intervention can improve outcomes.
- Any non-progressive brain injury occurring within the first two years of life (some sources say five) is considered CP.
Timeframe of Brain Injury
- CP occurs if the brain damage arises during one of these periods:
- Prenatal Period: Conception to the onset of labor
- Perinatal Period: 28 weeks intrauterine to 7 days
- Postnatal Period: First two years of life (some say five)
Epidemiology and Aetiology
- CP is the most common motor disability in childhood.
- Causes of CP are diverse and include:
- Congenital Factors
- Genetic Factors
- Inflammatory Factors
- Infectious Factors
- Anoxic Factors
- Traumatic Factors
- Metabolic Factors
- The brain injury can occur prenatally, during birth, or postnatally.
Diagnosis of CP
- CP diagnosis is based on clinical observations.
- It's not based on specific tests or imaging findings, leading to potential variability in diagnosis.
- Even medical professionals sometimes struggle to differentiate between certain CP types.
Life Expectancy
- Life expectancy is normal for most children with diplegia and hemiplegia with good medical care and family support.
- Some severely affected children with quadriplegia may die from complications like malnutrition or respiratory issues before reaching adolescence.
- In resource-limited areas, children with CP may not live past the age of five.
Classification of CP
- Classification helps group cases with similar characteristics and set realistic expectations for intervention.
- Classification considers:
- Severity: Mild, moderate, or severe
- Topographical Distribution: Which body parts are affected
- Muscle Tone: Hypertonia (increased muscle tone) or Hypotonia (decreased muscle tone)
Functional Classification Systems
- These systems assess functional abilities in areas like cognition, self-care, mobility, and social aspects.
- Examples include:
- Gross Motor Function Classification System (GMFCS)
- Manual Ability Classification System (MAC)
- Communication Function Classification System (CFCS)
Anatomical Classification
- Unilateral: One side of the body is affected.
- Bilateral: Both sides of the body are affected.
- Spastic CP is classified as either unilateral or bilateral.
- Dyskinetic CP and ataxic CP always involve the whole body (bilateral).
Spasticity
- Spasticity is increased resistance to passive muscle movement.
- It's a component of upper motor neuron damage and is characterized by hyperreflexia, clonus, and abnormal reflexes.
- Spastic CP is the most common type, accounting for 80% to 90% of cases.
Types of Spastic CP
- Hemiplegia (Unilateral): One side of the body is affected, often with the upper extremity more severely involved.
- Diplegia (Bilateral): Lower extremities are severely affected, with milder arm involvement.
- Quadriplegia (Bilateral): All four limbs, the trunk, and muscles controlling the mouth, tongue, and pharynx are involved.
Dyskinetic CP
- Abnormal involuntary movements occur when the child initiates movement.
- Often accompanied by:
- Dysarthria (speech difficulty)
- Dysphagia (swallowing difficulty)
- Drooling
- Intellectual development is typically normal, but communication challenges can create a false perception of intellectual impairment.
- Accounts for approximately 10% to 15% of all CP cases.
Ataxic CP
- Ataxia is loss of balance, coordination, and fine motor control.
- Ataxic children often have:
- Hypotonia in the first two years of life, followed by normal muscle tone and ataxia appearing around 2-3 years old.
- Wide-based gait
- Intention tremor
- Poor dexterity and fine motor control
- Associated with cerebellar lesions and sometimes combined with spastic diplegia.
Intervention with Cerebral Palsy
- Early intervention plays a crucial role in improving outcomes.
- Interventions can address difficulties in:
- Mobility
- Communication
- Self-care
- Cognitive Functioning
- Socialization
- The goal is to support the child's overall well-being and maximize their potential.
