Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.

UNIST introduces new robotic tool to improve mobility of stroke survivors

I must be missing something here since this talks about assessing/evaluating mobility not improving it.

A recent study, affiliated with UNIST has introduced a new robotic tool for assessments of muscle overactivity and movement dysfunction in stroke survivors. Their robotic-assisted rehabilitation therapy, combined with standard rehabilitation, is expected to improve the mobility of patients surviving a stroke.
This breakthrough research has been led by Professor Sang Hoon Kang of Mechanical, Aerospace and Nuclear Engineering at UNIST in collaboration with Professor Pyung-Hun Chang of DGIST and Dr. Kyungbin Park of Samsung Electronics Co. Ltd.
In their study, published in the May issue of the prestigious journal, IEEE Transactions on Neural Systems and Rehabilitation Engineering, Professor Kang and his team developed a rehabilitation robotic system that quantitatively measures the 3 degree-of-freedom (DOF) impedance of human forearm and wrist in minutes.
Using their impedance estimation device, entitled the distal internal model based impedance control (dIMBIC)-based method, the team was able to accurately characterize the 3 DOF forearm and wrist impedance, including inertia, damping, and stiffness, for the first time.
Stroke, known as a leading cause of long-term disability, is a sudden loss of brain function, caused by the interruption of blood flow to the brain or the rupture of a blood vessels in the brain and an estimated 150,000 people die from it, each year. As a consequence of stroke, stroke survivors are often left with muscle overactivity, including spasticity. Spasticity is a muscle control disorder that is characterized by tight or stiff muscles and an inability to control those muscles. It is often manifested by increased stretch reflex activity and mechanical joint resistance.
"The dIMBIC-based method can be used to assist in the quantitative and objective evaluation of neurological disorders, like stroke," says Professor Kang. "Findings from this study will open a new chapter in robot-assisted rehabilitation in the workplace accident rehabilitation hospitals, as well as in nursing homes and assisted living facilities."
The research team expects that, in the long run, the proposed 3 DOF impedance estimation may promote wrist and forearm motor control studies and complement the diagnosis of the alteration in wrist and forearm resistance post-stroke by providing objective impedance values including cross-coupled terms.
