- Researchers put volunteers through 20 hours of intensive rehabilitation training
- Some in randomized trials started as early as 30 days, 60 days, or 90 days after stroke.
- They found that two to three months was the best time to start treatment.
- Therapy focused on regaining arm and arm movement after a stroke event
According to a new study, stroke victims are able to recover more effectively if their rehabilitation does not begin until 2-3 months after the incident, but rather within weeks.
Researchers at Georgetown University Medical Center worked with 72 volunteers who suffered a stroke within three weeks of the trial.
They gave each volunteer 20 additional hours of intensive arm and hand movement therapy, randomized to begin 30, 60 or 90 days after their stroke.
They found that rehab was the optimal time in terms of improvement in hand and hand use, at least two to three months after the stroke.
They found that starting intensive rehabilitation six months or more after a stroke did not produce any significant benefits compared to standard care.

According to the Stroke Association, someone has a stroke every five minutes in the UK, affecting 100,000 people per year and 1.3 million stroke survivors.
About two-thirds of people who have a stroke are unable to recover full function in their hands and arms, an impairment that can severely limit everyday activities.
The new study suggests there is a ‘critical period’ when adults are most responsive to rehabilitation after a stroke, said lead author Alexander Dromerick.
‘Previous clinical trials have found few or very small improvements in motor function after stroke, so our research could be an important breakthrough in finding ways we can substantially improve hand and hand recovery. ‘
The volunteers came primarily from the Washington DC area, and were randomly timed to begin additional care in addition to their usual treatment.
The results were compared to a control group that only received their prescribed rehabilitation treatment but did not receive any additional motor rehabilitation training.

What are the warning signs of a mini stroke?
A transient ischemic attack (or, TIA) involves a temporary lack of blood flow to the brain, which causes transient dizziness, confusion, tingling, and numbness in the arms.
If you suspect that you may be suffering from a TIA, you should call 911.
- vision changes
- dysphasia (difficulty speaking)
- balance issues
- an altered level of consciousness
- passing out
- unusual sense of taste
- an unusual sense of smell
- Weakness or numbness on only one side of the body or face, determined by the location of the blood clot in the brain
“Our results suggest that more intensive motor rehabilitation should be provided to stroke patients 60 to 90 days after stroke onset,” said co-author Alyssa Newport.
‘It is well known that a young developing brain shows great plasticity compared to other times in life. Our results suggest that there may be a period of similarly increased plasticity for stroke patients at a specific time after their stroke.’
The team explained that the improvement in hand and hand function was not only statistically significant, but it was also large enough to be considered functionally meaningful by the patients.
Edwards, of the University of Wisconsin-Madison, said, “Our approach shows that patients can tolerate the more intense motor training traditionally provided, if they choose to choose the activities used in their training. are free.”
‘Knowing that there can be a critical period for recovery, there are a number of techniques one can imagine that may help to understand and enhance recovery during this period.’
The researchers hope this study will establish a time window in which future research can combine therapy with brain stimulation or drugs aimed at repairing impaired functions in the remaining healthy areas of the brain or lost functions from damage caused by stroke. to help take.
The investigators plan to design a larger clinical trial to confirm the current findings and determine the optimal dose of therapy, so that the best effects can be achieved during this time-sensitive window.
The findings have been published in the journal Proceedings of the National Academy of Science.
due to stroke
There are two major types of stroke:
1. Ischemic Stroke
An ischemic stroke — which accounts for 80 percent of strokes — occurs when there is a blockage in a blood vessel that prevents blood from reaching part of the brain.
2. Hemorrhagic Stroke
More rarely, a hemorrhagic stroke, occurs when a blood vessel ruptures, filling part of the brain with too much blood while denying adequate blood supply to other areas.
This may be the result of an AVM, or arteriovenous malformation (an abnormal group of blood vessels) in the brain.
Thirty percent of subarachnoid hemorrhage victims die before reaching the hospital. Another 25 percent die within 24 hours. And 40 percent of survivors die within a week.
Age, high blood pressure, smoking, obesity, sedentary lifestyle, diabetes, atrial fibrillation, family history, and history of a previous stroke or TIA (a mini-stroke) are all risk factors for having a stroke.
symptoms of a stroke
- sudden numbness or weakness of the face, arms, or legs, especially on one side of the body
- sudden confusion, trouble speaking or understanding
- Sudden trouble seeing or blurred vision in one or both eyes
- sudden trouble walking, dizziness, loss of balance or coordination
- Sudden severe headache with no known cause
