Post-stroke paralysis usually affects one side of the body. This condition is known as hemiparesis. Depending on the severity of the stroke and where it occurred in your brain, this paralysis can make it difficult to perform everyday activities such as grasping an object or walking.
There are treatment options that can help you recover movement on the affected side.
"Depending on the intensity and duration of the event leading to damage, recovery from stroke will be varied for each individual," said Vidhya Kannan, a physical therapist and CEO of Encompass Health Rehabilitation Hospital of Northern Virginia. "At a rehabilitation hospital, we'll try to restore as much function as possible using strategies supported by clinical research."
What causes stroke paralysis?
A stroke occurs when blood flow to the brain is interrupted. This may be caused by a blood clot or by an artery bursting, also known as a brain bleed. When blood flow is disrupted, brain cells are damaged. Because the brain controls how the body moves and functions, this damage can affect movement on one side of the body.
If a stroke occurs on the left side of the brain, weakness typically affects the right side of the body. If you have a right-sided stroke, weakness or paralysis will occur on the left side of the body.
"All of our functions are triggered by the brain," Kannan said. "When tissues in the brain are deprived of blood and are stressed, that affects part of your body. I compare it to the electrical panel in your home. If one is off cue, then that particular area in your house won't have power, so we have to reset the fuse and work on fixing the damage that might have occurred."
Can you recover from paralysis after a stroke?
With the right rehabilitation, it is possible to recover some or even all movement after stroke paralysis. Recovery varies based on the individual, how early rehabilitation begins and how severe the stroke was.
Early, consistent therapy is important because the brain is most responsive to change in the weeks and months following a stroke. Starting stroke rehabilitation as soon as it is medically safe can support better long-term outcomes.
How rehabilitation supports stroke paralysis recovery
Kannan said recovery focuses on restoring the brain and body connection by rebuilding damaged pathways or by creating new ones. This process is known as neuroplasticity.
"You have neuropathways for any body function to happen," she said. "This is what connects the body and the brain. When the connection is gone for a motor function or even speech, we try to stimulate disrupted pathways to help with the reconfiguration through evidence-informed practice or to create alternate pathways."
If function cannot be restored on the affected side, the care team may work with you on compensatory strategies to help manage one-sided weakness. “That is a last resort," Kannan said.
Therapies used to treat one-sided stroke paralysis
There are a variety of treatment options and strategies to address stroke paralysis. The recommended therapies depend on the severity of your stroke and the setting you are recovering in. A combination of occupational, speech and physical therapy after stroke is recommended. Early, intensive therapy can lead to better outcomes.
In an inpatient rehabilitation setting, you will receive at least three hours of therapy a day, five days a week. You will also have frequent physician visits and 24/7 nursing care.
Some techniques used to improve movement include:
- Electrical stimulation: Electrical pads are placed on the weakened side of the body, and a gentle electric current stimulates the muscles to help restore the neuromuscular function.
- Mirror therapy: Often used after limb loss, mirror therapy uses a mirror to help the brain perceive movement in the affected limb.
- Constraint-induced movement therapy: This approach limits movement in the unaffected side of the body to encourage use of the weaker side. A modified version may be used for weeks after your stroke.
- Neurodevelopmental therapy: This is an advanced, hands-on therapy provided by a physical or occupational therapist who specializes in neuro development to stimulate function and movement.
Choosing a provider for stroke paralysis recovery
Once your condition is stable, your physician may recommend continuing your treatment in another setting. Depending on your condition, this could be a skilled nursing facility or an inpatient rehabilitation hospital. Taking time to research your options can help you choose the right level of care.
According to the American Heart Association and American Stroke Association stroke guidelines, when possible, stroke recovery should take place in the inpatient rehabilitation hospital instead of a skilled nursing facility.
Inpatient rehabilitation hospitals are required to provide a minimum of three hours of therapy at least five days a week. Length of stay for inpatient rehabilitation patients varies by individual but is typically around two weeks. A skilled nursing facility will have a longer length of stay — around 28 days — and has no minimum therapy requirements.
Kannan said you should also consider the provider's expertise in treating stroke and stroke paralysis.
"If I were the caregiver or the patient, I would want to know if they have a specialized program for treating stroke,” she said. “Anything specific to stroke treatment would definitely be an advantage.” Across the country, Encompass Health hospitals hold nearly 150 Disease-Specific Care Certifications in stroke rehabilitation from the Joint Commission.
You should also ask whether the provider creates individualized treatment plans, Kannan added. In an inpatient rehabilitation hospital, a rehabilitation physician leads a care team that designs a plan specific to your goals, lifestyle and needs.
"Our programs are very individualized to the person," Kannan said. "Identify what your top priority for recovery is, so your care team can build a treatment plan around that."
