What Is Spastic Diplegia?

Cerebral palsy is a group of disorders that originate in the brain and impact muscle movement, balance and posture. According to the CDC, spastic cerebral palsy, characterized by muscle stiffness, is the most common type. This can impact any or all of the limbs. The term “diplegia” indicates the involvement of both sides of the body, especially the legs. Spastic diplegia is a type of spastic cerebral palsy that impacts both legs with little or no involvement of the arms. The stiffness can originate in the hips or the legs themselves and cause difficulty walking.

Spastic diplegia often occurs as a result of birth injuries due to medical malpractice. Caring for a child with spastic diplegia requires a significant commitment of time and financial resources that can be overwhelming.

The birth injury attorneys at Levin & Perconti specialize in holding negligent health care providers accountable and ensuring parents receive substantial compensation so they have the resources they need to access the most advanced therapies available.

Prevalence of Spastic Diplegia in Children

According to data compiled by the Centers for Disease Control, cerebral palsy is the most common childhood motor disability, impacting about one in 345 children in the United States. This equates to three cases per 1,000 8-year-old children. Globally, cerebral palsy occurs in one to four of every 1,000 births. It has declined in some parts of the world, indicating it is preventable.

Spastic diplegia is the most common clinical phenotype of cerebral palsy, according to Translational Pediatrics, whose 2020 study found that 35 percent of children with cerebral palsy have spastic diplegia.

Spastic Diplegia Symptoms

It is important to identify the signs and symptoms of spastic diplegia as early as possible so your child can receive the necessary interventions to develop healthy movement techniques while their muscles are developing.  

Most children with spastic diplegia do not experience impaired cognitive functioning. Symptoms are primarily associated with movement. 

Abnormal Gait 

Nearly every child with spastic diplegia experiences abnormal walking patterns due to the stiffness of their muscles. This can manifest in the following ways: 

  • Scissor gait – Walking while the knees are turned outward 
  • Walking on the toes
  • Crouch gait – Walking with the knees, hips and ankles continuously bent 

Muscle Weakness 

The muscle tightness and difficulties with walking may discourage children from engaging in physical exercise, which can create a vicious cycle of increased weakness leading to less activity, leading to more weakness, and so on. Muscle weakness exposes the child to an increased risk of injury. 

Delayed Developmental Milestones 

Children with spastic diplegia may take longer than other children to crawl, stand or walk. This does not mean they will never walk. As many as 50 to 60 percent of children with cerebral palsy eventually walk without assistance. If the spasticity is severe, children can be taught at a young age to walk with assistive equipment. 

Impaired Growth and Development 

Children can develop additional deformities in their effort to compensate for difficulties. For example, one leg may grow longer than the other if the child relies on one leg too much. This underscores the importance of early intervention and treatment. 

Causes and Etiology of Spastic Diplegia

Spastic diplegia is caused by damage to the motor cortex of the brain. This causes compromised transmission of signals from the brain to the muscles. As a result, the muscles remain in a constant state of involuntary contraction. 

Birth Asphyxia 

This type of brain damage can occur during the birthing process, especially during complicated births. Fast, decisive action is often called for to ensure the infant is not deprived of oxygen during any phase of the labor and birthing process. When the infant is deprived of oxygen during the birthing process, this is called birth asphyxia. 

The following conditions during birth can lead to asphyxia: 

Hypoxic Ischemic Encephalopathy (HIE) 

Hypoxic ischemic encephalopathy is a brain disorder that occurs when the body’s blood flow and oxygen levels are insufficient. Causes of HIE during or shortly after labor and delivery include the following: 

  • Umbilical cord issues
  • Rupture of the uterus
  • Excessive placental bleeding
  • Abnormal fetal position
  • Prolonged late stages of labor
  • Low blood pressure in the mother or baby
  • Severe prematurity
  • Lung or heart issues
  • Infections
  • Brain or skull trauma 

If fetal distress, low heart rate or respiratory difficulties occur during or after labor or delivery, health care providers should suspect and check for HIE.

Risk Factors of Spastic Diplegia in Children

Multiple factors can contribute to the risk of a child developing spastic diplegia during pregnancy, but infants with the following circumstances are especially vulnerable during and shortly after the birthing process: 

  • Preterm birth 
  • Low birth weight 
  • Complicated labor and delivery
  • Jaundice
  • Seizures 

How is spastic diplegia diagnosed in children?

According to the Mayo Clinic, before spastic diplegia can be diagnosed cerebral palsy must first be confirmed through a brain scan, such as an MRI or cranial ultrasound. Spastic diplegia can then be diagnosed through the observation of spasticity in the legs. Additional tests may be required, such as the following: 

  • An EEG to rule out seizure disorders
  • Blood, urine or skin tests to screen for metabolic or genetic issues
  • Tests to determine any other conditions associated with cerebral palsy
    • Vision
    • Hearing
    • Speech
    • Cognitive
    • Development
    • Movement 

Spastic Diplegia Treatment and Prognosis

Spastic diplegia is a lifelong condition. It is not considered a progressive condition, which means it does not get worse. Individuals with spastic diplegia can enjoy a high quality of life if they receive the proper treatment. Treatment approaches vary between individuals because the disorder affects muscle groups differently and to varying degrees of severity. 


Effective spastic diplegia treatment focuses on neuroplasticity, a mechanism that rewires the brain to control functioning from healthy areas instead of from the damaged portions. The most effective method to promote neuroplasticity is through repetition of specific tasks. The greater the repetition, the stronger the new neural pathway will be. This can work at any age but is most effective at young ages. 

Physical Therapy 

Physical therapy can include the following: 

  • Stretching spastic muscles
  • Strengthening underused muscles
  • Gait training
  • Balancing challenges 

Occupational Therapy 

Occupational therapists teach individuals with spastic diplegia how to perform daily activities such as dressing, toileting and bathing. If needed, this includes teaching patients how to use assistive equipment correctly. 

Muscle Relaxants 

Muscle relaxants may be injected into the legs to provide temporary relief of spasticity in conjunction with long-term approaches. 


Spasticity can interfere with growth and cause complications such as hip dislocations. Orthotics can stretch the muscles to reduce tightness and help the body maintain proper alignment. These devices also help with walking and transferring from one place to another. 


Surgery may be recommended in severe cases to manually lengthen muscles, realign them or reduce the excitability of spastic muscles by permanently severing certain nerve roots.
