Understanding Ataxia in Stroke Patients: A Cerebellar Stroke Effect

treating ataxia in stroke patients with balance exercises

When a stroke affects the cerebellum, it can result in a secondary effect known as ataxia.

Ataxia involves a lack of coordination and muscle control due to neurological dysfunction. This means the nervous system struggles to coordinated movement.

You’re about to learn why ataxia after stroke is associated with the cerebellum and how the condition is treated through rehabilitation.

Understanding Ataxia in Stroke Patients

The cerebellum is an area of the brain that is responsible for controlling coordination, balance, and voluntary muscle control.

When you move your body, it’s because your brain sent signals to your muscles telling them to move. Although some movements are simple, it is a complex process that involves many different functions and areas of the brain, including the cerebellum.

When other areas of the brain initiate movement, the cerebellum modifies those motor commands to make movements more accurate and coordinated. When the cerebellum becomes damaged and cannot help coordinate movement, ataxia can occur.

One way that the cerebellum can become damaged is from a stroke. A stroke occurs when the supply of blood in the brain is compromised by a clogged or burst artery. When a stroke affects the cerebellum, it can damage the brain tissue in this area and impair the cerebellum’s function.

Symptoms of Ataxia

Ataxia can affect different muscles in the body and result in different symptoms.

For instance, when the legs and trunk are affected, it can cause the individual difficulty with balance and walking. Or when the oral muscles are affected it can cause individuals to slur their speech.

Ataxia manifests differently in everyone. Here are some signs of ataxia in stroke patients to look for:

  • Poor coordination
  • Unsteady gait
  • Wide stance and wide based gait
  • Difficulty with fine motor skills
  • Slurred speech or difficulty with speech (ataxic dysarthria)
  • Eye movement abnormalities
  • Difficulty with eating and swallowing (dysphagia)
  • Intention tremors

It’s important to work with a therapist to diagnose any motor issues you may have and create a unique treatment plan for you.

While there is no medication that can cure damage to the cerebellum (or any other area of the brain) improvements are often possible through rehabilitation.

Restoring the Mind-Muscle Connection

Because ataxia stems from miscommunication from the brain, rehabilitation involves restoring as much of this communication as possible. This is possible thanks to neuroplasticity: the brain’s ability to create and strengthen neural connections.

Neuroplasticity is how all skills are learned, and this is how skills such as balance can be re-learned after a stroke.

When a skill is practiced regularly, the brain attempts to become more efficient at that skill by strengthening the neural pathways required to execute that function. This is why riding a bike regularly helps improve your ability to ride a bike.

It’s important to emphasize that ataxia is caused by miscommunication from the brain, not loss of muscle strength. Stroke patients can show loss of coordination even when muscle strength has been relatively well-preserved.

Therefore, improving coordination after ataxia is a matter of practicing coordinated movement. As you’ll see next, there are many therapies available that help with this.

Rehabilitation for Ataxia After Stroke

Ataxia can affect movement in any area of the body, so there are a wide variety of therapies available based on your symptoms.

Below are a list of rehabilitative therapies to help treat ataxia in stroke patients:

1. Physical Therapy

During physical therapy, your therapist will guide you through specific exercises to help improve balance and coordination. Your therapist will likely focus on exercises for the legs and trunk because these muscle groups are often affected by ataxia.

It’s important to keep up with physical therapy exercises on your own at home to keep the brain stimulated and encourage neuroplasticity. This is where home therapy programs can help, such as Flint Rehab’s FitMi home therapy.

FitMi helps stroke survivors regain movement by motivating you to accomplish high repetition of physical therapy exercises. Users can select which muscles to target, such as the legs and trunk, which can help address ataxia.

2. Occupational Therapy

Occupational therapy also helps individuals regain mobility, particularly with the activities of daily living such as eating. When ataxia affects your ability to use the bathroom on your own, for example, an occupational therapist will help you with this goal (either through rehabilitation exercise or compensation techniques).

3. Speech Therapy

If ataxia causes slurred speech, a Speech-Language Pathologist can help. It’s important to work closely with an SLP because these experts understand the differences between speech conditions.

For instance, apraxia of speech is different than aphasia, another speech disorder that can occur after a stroke. Apraxia of speech is a motor disorder (affecting the oral muscles) while aphasia is a linguistic disorder (affecting various cognitive aspects of speech such as reading or comprehension).

Both conditions are treated with different exercises, which makes it essential to be diagnosed by an SLP before beginning speech therapy exercises.

Recovering from Ataxia After Stroke

Every stroke is different and every recovery is different. The best therapy for ataxia after stroke depends upon the individuals unique symptoms.

Work closely with your therapists to create a rehabilitation regimen that targets your specific goals. Then, keep up with therapy on your own between visits with your therapist. The brain requires consistent stimulation to rewire itself and re-learn skills such as coordinated movement. As you put in the work and practice therapeutic exercises for apraxia, your coordination can continue to improve over time.

Mom gets better every day!

“When my 84-year-old Mom had a stoke on May 2, the right side of her body was rendered useless. In the past six months, she has been blessed with a supportive medical team, therapy team, and family team that has worked together to gain remarkable results.

While she still struggles with her right side, she can walk (with assistance) and is beginning to get her right arm and hand more functional. We invested in the FitMi + MusicGlove + Tablet bundle for her at the beginning of August.

She lights up when we bring it out and enjoys using it for about 20 to 30 minutes at a time. While she still doesn’t have enough strength to perform some of the exercises, she rocks the ones she can do!

Thanks for creating such powerful tools to help those of us caring for stroke patients. What you do really matters!”
