Non-spastic cerebral palsy, also known as extrapyramidal cerebral palsy, accounts for around 20% of all cases of the disorder in the United States.
What is Non-Spastic Cerebral Palsy?
Non-spastic cerebral palsy is marked by decreased muscle tone that tends to fluctuate.There are two major types of non-spastic cerebral palsy, with some sub-types, and each one has its own set of characteristics. However, all forms of non-spastic cerebral palsy will have muscle tone variations, that will go from floppy to stiff.
Dyskinetic Cerebral Palsy
Dyskinetic cerebral palsy is a form of non-spastic cerebral palsy that’s separated into sub-groups: athetosis (see below for more information), dystonia and chorea.
Symptoms of athetosis include:
- Involuntary slow, “stormy” movements
- Arms, feet, hands, and legs may have writhing movements
- Fluctuating muscle tone (from stiff to floppy)
- Facial grimacing and drooling from poor control of facial muscles
- Difficulty eating and drinking due to poor coordination of swallowing muscles
- Difficulty grasping and holding small objects due to changing muscle tone
- Involuntary movements may be continuous unless the child is totally relaxed
- Involuntary movements typically disappear when the child is asleep
Symptoms of dystonia include:
- Abnormal and awkward posture
- Repetitive, twisting, or jerky movements
- Movements that alternate from slow and painful to fast and rapid
- Involuntary movements are triggered by movement
- Muscle spasms and involuntary movements that increase when the child is stressed or tired
- Dystonia may affect only one part of the body or all of the body
Symptoms of chorea may include:
- Abrupt, fidgety movements
- Unpredictable movements
- May appear uncoordinated or clumsy
Ataxic Cerebral Palsy
Ataxic cerebral palsy is another form of non-spastic cerebral palsy, and is also the rarest type of the disorder, affecting around only 5% to 10% of all cases.
Ataxic cerebral palsy comes with its own set of distinct characteristics and symptoms, which may include:
- Problems with balance, depth perception and coordination
- Difficulty walking
- Tremors (especially when reaching for things)
- Difficulty making quick movements
- Difficulty with precise finger movements, such as writing
- Breathy sounds and monotone voice when speaking, known as “scanning” speech
- Slow eye movements
- Hearing and vision problems
Treatment Options for Non-Spastic Cerebral Palsy
Physical therapy is a set of exercises and physical interventions usually recommended for children with non-spastic cerebral palsy, regardless of how minor or severe the condition is. Physical therapy may involve hydrotherapy, exercise, massage, practice with movements, standing devices. It provides numerous benefits, including help with balance, coordination, muscle strength, physical endurance, and confidence.
Speech and language therapy is recommended to help children with non-spastic cerebral palsy who need assistance communicating effectively, a problem that can affect children with all forms of cerebral palsy. It helps the child to overcome language difficulties such as aphasia, dysphagia, stuttering, and more.
Many children with non-spastic cerebral palsy benefit from medications that help control abnormal muscle movements and tremors. Your child’s physician will tell you about medicines that may work best for particular symptoms. Sometimes, in mild cases of non-spastic cerebral palsy, medication may not be needed.
In rare instances, especially when medication isn’t working, children with non-spastic cerebral palsy may need to undergo surgery, typically orthopedic surgery to help correct limb problems and deformities.
Non-Spastic Cerebral Palsy Prognosis
The long-term outlook for children with non-spastic cerebral palsy will depend upon how severe the disorder is, any associated medical conditions, and how well treatment options work. Generally, children with non-spastic cerebral palsy can live long, productive lives with the right treatment plan and care.
