Understanding Sensory Problems Due to Cerebral Palsy

Is it possible to have sensory problems due to cerebral palsy?

Although cerebral palsy is a motor disorder, it’s relatively common for children with CP to also have co-occurring sensory problems.

Generally, these deficits won’t be due to problems with the senses themselves, but rather from damage to the area of the brain responsible for processing sensory information.

Risks Associated with Sensory Problems and CP

Sensory processing abnormalities in children with cerebral palsy can come in the form of hypersensitivity or hyposensitivity.

Those with hypersensitivity may be avoidant of physical touch, crowds, and loud sounds because they have heightened senses.

In contrast, those with hyposensitivity will have decreased sensory processing and may not respond to stimuli because the brain cannot process it.

Sensory deficits can negatively affect a child’s:

  • activity levels
  • communication skills
  • learning
  • interactions with their surroundings

Sensory Problems Due to Cerebral Palsy

Not all children with cerebral palsy are going to have sensory deficits.

In fact, sensory problems and cerebral palsy aren’t even directly related.

Although they commonly co-occur, they’re caused by different sources of brain damage.

In this study of 96 children with cerebral palsy, sensory deficits were present in 41.7%.

Additionally, a high correlation was found between the severity of sensory problems and hand function.

Researchers concluded that “moderate to severe motor disability was associated with severe sensory dysfunction”.

In other words, more severe forms of cerebral palsy are associated with greater levels of damage to the brain, which increases the risk of co-occurring sensory impairments.

Types of Sensory Deficits Common in Children with Cerebral Palsy

Because sensory deficits can be caused by many sources of brain damage, people with cerebral palsy can technically have any form of sensory impairment.

However, some are definitely more common than others.

Vision Impairments

It’s suggested that up to 90% of all children with cerebral palsy have some sort of visual impairment.

While mild visual impairments are very prevalent, only about 10% will have a severe visual impairment.

Cortical vision impairments are the result of the brain not being able to process what the eyes see.

Children with cortical vision impairments may demonstrate delayed reactions, blank staring, difficulty recognizing familiar faces, an attraction to shiny or bright objects, and be overwhelmed by clutter.

Hearing Loss

There are 3 types of hearing impairments children with cerebral palsy can experience:

  • Sensorineural hearing loss is the most common type of hearing impairment. It’s the result of nerve pathway damage in the inner ear.
  • Conductive hearing loss is when sound transmission in the middle and outer ear is interrupted. Unlike sensorineural hearing loss, conductive hearing loss is usually temporary and can be treated.
  • Mixed hearing loss is when a person experiences symptoms of both sensorineural and conductive hearing loss. With mixed hearing loss, multiple areas of the ear are affected.

Hearing impairments can harm your child’s communication skills if not properly managed.

Most hearing impairments can be improved through medications, hearing aids, surgery, or cochlear implants.

Tactile Impairments

Tactile impairments refer to problems with one’s sense of touch.

An insufficient sense of touch makes it difficult for children to understand the characteristics of their surroundings, which will discourage them from interacting with their environment.

It is essential for children to explore what’s around them in order to develop sensory coordination and to understand what is safe or not.

Poor Proprioception

Proprioception refers to one’s sense of body positioning and spatial awareness.

Proprioceptors (the receptors for this sense) are located in the joints and muscles.

Abnormal muscle tone will interfere with proprioception and impair balance, coordination, and posture.

Managing Sensory Problems in Children with Cerebral Palsy

sensory integration therapy for cerebral palsy

Children will go to sensory integration therapy to improve their sensory processing skills.

Trained therapists will have the child participate in activities specifically designed to stimulate the senses.

The idea behind sensory integration therapy is that over time, continuous sensory stimulation will train the brain to rewire itself (neuroplasticity) and improve it’s sensory processing skills.

It’s crucial for parents of children with cerebral palsy to keep an eye out for symptoms of sensory problems like delayed reactions, avoidant behavior, and poor coordination.

Unlike adults who get neurological damage due to a traumatic injury, children with sensory deficits are born with them and don’t necessarily understand what it’s like to have normal sensory functions.

The younger you are, the more adaptable your brain is. Early intervention is key for improving sensory processing skills and preventing the negative consequences of sensory deficits from developing.

Hopefully, this article helped you better understand the link between cerebral palsy and sensory deficits. Although brain damage cannot be reversed, the brain can be trained to adapt with enough repetition.

Good luck!

Keep It Going: Discover a home exercise program for CP that’s actually fun to do!

Finally! There’s a recovery device for CP that’s actually fun to use. See how Flint Rehab’s tools are helping with CP recovery:

“The FitMi and MusicGlove have done wonders for my son with hemiparesis from cerebral palsy and stroke.

It motivates him to do his exercises. It does not seem like therapy for him since it is fun. It monitors his progress so it is a great reinforcement for him.

Music is a motivator for him. He has been using it on his arm and we will try the leg exercises soon.”

FitMi works by motivating high repetition of therapeutic exercises while playing an engaging game. This gamification has been particularly great for motivating individuals with cerebral palsy to recover.
