Deans' stroke musings: KIST finds a strong correlation between ultrasonic stroke rehabilitation treatment and brain waves

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

KIST finds a strong correlation between ultrasonic stroke rehabilitation treatment and brain waves

In mice so your doctors and stroke hospital will have to contact researchers to get human testing going. THEIR RESPONSIBILITY, don't let them weasel out of it.

KIST finds a strong correlation between ultrasonic stroke rehabilitation treatment and brain waves

The Korea Institute of Science and Technology (KIST) announced that a research team led, by Dr. Hyungmin Kim at the Center for Bionics, Biomedical Research Institute of the KIST, found a strong correlation between a ultrasonic stroke rehabilitation method for treating damaged brain and a change in delta waves, which is a type of brain waves.

A stroke is the result of a cerebrovascular hemorrhage/infarction and is a disease with a high mortality rate. Even when a stroke does not lead to death, it results in the blockage of the affected person's blood supply and damage to the nerve cells, causing the impairment of physical movement. Many researches are underway on post-stroke rehabilitation methods that can be used to repair damaged brain.

Dr. Hyungmin Kim of the KIST recently published a study on hemiparalysis treatment for motor function recovery, a treatment in which the deep cerebellum is stimulated using low-intensity focused ultrasound stimulation (Neurorehabil Neural Repair. 2018 Sep;32(9):777-787). This treatment method, which can be used to treat stroke patients with various brain lesions, has received much attention as it does not require surgical procedures and can be used to selectively stimulate deeper parts of the brain areas.

To apply this method for various stroke treatments, a 'stimulation guide' is required. This can be used to assess the patient's prognosis after brain stimulation and to optimize the intensity and frequency of the stimulation for maximizing motor function recovery.

In order to develop such a guide, the KIST research team observed changes in the brain waves of the nerve cells of stroke lesions during treatment. In particular, the research team observed and analyzed changes in delta waves (1-4 Hz), which abnormally increase in brain lesions, in both the normal cerebral hemisphere and the cerebral hemisphere affected by the legion.

The KIST research conducted the ultrasound stimulation treatment on the deep cerebellum of mice for three days. On the first day, the motor functions of the mice improved almost three-fold, and on the fourth day, the mice were able to retain their improved motor functions. During the experiment, changes in the delta waves were observed, which increased up to three times, confirming that interhemispheric balance was retained and held steady at a normal level in the ultrasound stimulation group.

The study found that ultrasound stimulation can suppress delta waves and induce a change in damaged brain, signifying the improvement of motor functions. If a patient-specific ultrasound stimulation method can be developed by monitoring brain waves, this type of treatment can be translated from animal experimentation to actual patient treatment.

"Given that ultrasound brain stimulation progresses at a rapid pace and given that it is being studied in relation to various brain diseases, it will likely be used as an effective stroke treatment in the near future," said Dr. Hyungmin Kim of the KIST. "In order to develop an ultrasound stimulation treatment, it is essential to verify the safety of such treatment based on the careful observation and long-term tracking of various stimulation conditions."

The research, supported by the Ministry of Science and ICT (MSIT), was conducted as part of the Creative Conversion Research Project of the National Research Council of Science & Technology (NST). A journal article explaining the results of the research was published in the latest issue of IEEE Transactions on Neural Systems & Rehabilitation Engineering, an international journal on rehabilitation.
