Spastic quadriplegia cerebral palsy is a severe form of cerebral palsy characterized by **spasticity (muscle stiffness and tightness) affecting all four limbs—both arms and legs—as well as the trunk and neck muscles**. This condition results from damage to the brain areas responsible for voluntary muscle control, particularly the **motor cortex and pyramidal tracts**, which send movement signals from the brain to the muscles[1][3].
Cerebral palsy (CP) itself is a group of permanent neurological disorders that affect movement, posture, and muscle coordination due to non-progressive brain injury or abnormal brain development occurring before, during, or shortly after birth[4][5]. Spastic CP is the most common type, accounting for about 77% of all CP cases, and spastic quadriplegia is the most severe subtype within this category[1][6].
### What Causes Spastic Quadriplegia Cerebral Palsy?
Spastic quadriplegia arises when the brain damage is widespread, affecting both hemispheres and the areas controlling all limbs. Causes include:
– **Prenatal brain injury** due to infections, inflammation, or genetic factors.
– **Perinatal complications** such as lack of oxygen (hypoxia) during labor and delivery.
– **Premature birth** and very low birth weight increase risk.
– **Neonatal brain hemorrhage or stroke**.
– **Severe jaundice (kernicterus)** or infections in early infancy[3][4].
The damage disrupts the brain’s ability to regulate muscle tone, leading to excessive muscle contraction (spasticity) and poor motor control[1][4].
### Symptoms and Characteristics
Children with spastic quadriplegia typically exhibit:
– **Severe muscle stiffness and tightness in all four limbs**, making voluntary movement difficult or impossible.
– **Weak or floppy neck and trunk muscles**, impairing head control and posture.
– **Limited or no ability to walk**, often requiring wheelchairs or other assistive devices.
– **Difficulty with fine motor skills**, such as grasping or releasing objects.
– **Delayed developmental milestones**, including sitting, crawling, and walking.
– **Possible speech difficulties** due to impaired muscle control of the mouth and throat.
– **Joint deformities and contractures** caused by chronic muscle tightness.
– **Associated conditions** such as intellectual disabilities, seizures, or vision and hearing impairments may also be present but vary widely[1][3][6].
### How Spasticity Affects Movement
Spasticity in quadriplegia means muscles are continuously contracted, which restricts smooth, coordinated movements. This can cause:
– **Scissoring gait** if the child attempts to walk, where legs cross over each other.
– **Clenched fists or tight fingers** that are difficult to open.
– **Difficulty with balance and posture**, leading to frequent falls or inability to sit unsupported.
– **Pain and discomfort** from muscle stiffness and joint stress[1][3].
### Diagnosis
Diagnosis is primarily clinical, based on observing abnormal muscle tone, reflexes, and movement patterns. Brain imaging (MRI or CT scans) can identify the extent and location of brain injury. Early diagnosis is crucial for timely intervention[5].
