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.

Design of a device for post-stroke rehabilitation of the hand

I bet you'll have to compare this to all the previous ones yourself. 

Design of a device for post-stroke rehabilitation of the hand

Author: BARZANI, LUCA Supervisor: COVARRUBIAS RODRIGUEZ, MARIO Scientific Disciplinary Sector: ING-IND/15 DISEGNO E METODI DELL'INGEGNERIA INDUSTRIALE Date: 19-Dec-2018 Academic year: 2017/2018 Title: Design of a device for post-stroke rehabilitation of the hand Italian abstract: La tesi presenta la progettazione di un esoscheletro per la riabilitazione della mano. Il sistema è pensato per pazienti che soffrono di paralisi di una mano, come conseguenza di ictus, che porta ad un significativo deficit nelle azioni di tutti i giorni. È stato provato che il processo riabilitativo è in grado di portare grandi miglioramenti, ma ciò necessita la costante presenza di un tutor. Per questo motivo vengono progettati sistemi che aiutano il paziente ad eseguire esercizi in autonomia. Il progetto parte da una descrizione generale dell’ictus. Vengono poi presentate una rassegna dello stato dell’arte e considerazioni meccaniche e anatomiche sulla mano umana. Dopodiché, viene esposta un’analisi dettagliata dell’esoscheletro. L’obiettivo del progetto è di realizzare un dispositivo leggero ed economico, che possa essere usato anche a casa. L’esoscheletro deve essere in grado di riprodurre i movimenti sulla mano paralizzata, senza l’intervento di un tutor. Per sviluppare queste caratteristiche sono stati sviluppati diversi aspetti riguardanti l’applicazione, come ergonomia, regolabilità e semplicità d’uso. Da queste considerazioni sono stati ricavati i parametri che guidano la progettazione. Il sistema ha due modalità d’uso. Nella prima, l’esoscheletro esegue esercizi decisi dal tutor su un computer. La seconda modalità prevede un’operazione di specchiatura, in cui la mano sana indossa un guanto con sensori. L’esoscheletro e il guanto comunicano, in modo che la mano sana guidi i movimenti dell’altra mano. English abstract: This paper presents the design of an exoskeleton for hand rehabilitation. The system is intended for people suffering an impairment of fingers as consequence of a stroke, which leads to a significant deficit in hands everyday activities. Rehabilitation process has been proven to bring great benefits, but the constant presence of a tutor is needed. To overcome this issue, systems that allow the patient to perform the training by himself have been designed. The project starts from an overall description of stroke phenomenon, under different points of view. After that, a state of the art review is presented, following mechanical and anatomical considerations about the hand. Then, a complete review of the exoskeleton design is presented. The objective of the project is to design a lightweight and affordable device that can be used at home. This device should be able to reproduce training movements on an impaired hand, without the intervention of a tutor. For implementing these features, many aspects related to the application have been considered, like ergonomics, adjustability and usability. These considerations, allowed to determine project driving parameters. The system has been designed with two directions of use, depending on the rehabilitation therapy. In the first mode, the exoskeleton is linked to a computer and performs exercises decided by the therapist on the PC. The second mode is a mirroring action, where the healthy hand wears a glove with sensors. In this modality, exoskeleton and glove communicate so that the motion of healthy hand drives the movements of the impaired hand. For the realization of most components a 3D printer has been adopted, using PLA and TPU materials. For exoskeleton motion, 13 linear actuators have been employed. Control system is based on Arduino UNO and Arduino NANO boards, and communicates with the computer through a Unity program, also used for developing user interface.
