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.

Intracerebral implantation of human neural stem cells and motor recovery after stroke: multicentre prospective single-arm study (PISCES-2)

Using the Action Research Arm Test for validation is not useful, it is subjective.

I see nothing here that suggests that any objective damage diagnosis was done. Without having a valid starting point this research can't be replicated.

Intracerebral implantation of human neural stem cells and motor recovery after stroke: multicentre prospective single-arm study (PISCES-2)

Abstract

Background Human neural stem cell implantation may offer improved recovery from stroke. We investigated the feasibility of intracerebral implantation of the allogeneic human neural stem cell line CTX0E03 in the subacute—chronic recovery phase of stroke and potential measures of therapeutic response in a multicentre study.
Methods We undertook a prospective, multicentre, single-arm, open-label study in adults aged >40 years with significant upper limb motor deficits 2–13 months after ischaemic stroke. 20 million cells were implanted by stereotaxic injection to the putamen ipsilateral to the cerebral infarct. The primary outcome was improvement by 2 or more points on the Action Research Arm Test (ARAT) subtest 2 at 3 months after implantation.
Findings Twenty-three patients underwent cell implantation at eight UK hospitals a median of 7 months after stroke. One of 23 participants improved by the prespecified ARAT subtest level at 3 months, and three participants at 6 and 12 months. Improvement in ARAT was seen only in those with residual upper limb movement at baseline. Transient procedural adverse effects were seen, but no cell-related adverse events occurred up to 12 months of follow-up. Two deaths were unrelated to trial procedures.
Interpretation Administration of human neural stem cells by intracerebral implantation is feasible in a multicentre study. Improvements in upper limb function occurred at 3, 6 and 12 months, but not in those with absent upper limb movement at baseline(So dead brain areas like mine would not be helped.), suggesting a possible target population for future controlled trials.

Stem cell stroke treatment trial results 'show promise'

You'll have to read this yourself and see if it shows promise. At least it is for chronic so you don't have spontaneous recovery to confound the study.
The press release here; 

Stem cell stroke treatment trial results 'show promise' 


The trial itself here;
Pilot Investigation of Stem Cells in Stroke (PISCES)

Purpose
The study is designed to test the safety of a manufactured neural stem cell line (CTX cells) delivered by injection into the damaged brains of male patients 60 years of age or over who remain moderately to severely disabled 6 months to 5 years following an ischemic stroke. In addition the trial will evaluate a range of potential efficacy measures for future trials. Treatment will involve a single injection of one of four doses of CTX cells into the patient's brain in a carefully controlled neurosurgical operation performed under general anesthetic. The trial is designed to treat 12 patients and measure outcomes over 24 months. Patients will be invited to participate in a long-term follow-up trial for a further 8 years.

Encouraging data from stem cell trial in stroke patients as plans for Phase II progress

I am somewhat concerned that they talk about enrolling stroke patients, all of whom will have suffered a stroke within a few weeks. That means there is no way to split off spontaneous recovery from any boost provided by the stem cells. Bad science.

Updated interim data from the PISCES trial, which has seen the brains of ischaemic stroke patients injected with neural stem cells to test the safety and tolerability of the treatment, was presented to the 22nd European Stroke Conference in London today. Professor Keith Muir of the University of Glasgow, who is heading the trial of ReNeuron Group plc's ReN001 stem cell therapy at the Southern General Hospital, Glasgow reported that data from the first nine patients treated has shown no cell-related or immunological adverse affects. He added that most patients had experienced sustained modest reductions in neurological impairment compared to their pre-treatment baseline performance, accompanied by improvement in abilities to undertake day to day tasks. A further two patients have been treated since the data were collated and the trial is now drawing to a close, with full results due to be published next year. Meanwhile, plans are proceeding for a Phase II trial which will examine the efficacy of stem cell treatment in stroke patients and an application is expected to be submitted to the UK regulatory authorities in early July. If approved the Phase II trial is scheduled to commence later this year. The Phase II trial will be a controlled multi-centre trial involving around 20 patients initially, all of whom will have suffered a stroke within a few weeks. Professor Muir said: "We remain pleased and encouraged by the data emerging from the PISCES study. The data to date identify no safety issues with the ReN001 treatment – which is the primary focus of this Phase I trial. "The evidence of functional improvement requires further investigation in a suitably designed Phase II efficacy study and we look forward to being a principal clinical site in that study when it commences." Michael Hunt, Chief Executive Officer of ReNeuron, said: "The PISCES study continues to yield encouraging results. Assuming the remaining required short-term follow up data confirm the good safety profile of the treatment, we will be able to move the ReN001 therapy confidently into Phase II clinical development, as planned, later this year." The Phase II study plan has been adopted by the NHS National Institute for Health Research Stroke Research Network (SRN). This important endorsement will enable ReNeuron to work closely with the SRN to optimise performance against defined targets regarding site set-up, patient recruitment and monitoring activities across the various sites participating in the study. ReNeuron will seek final regulatory and ethical approvals for the Phase II stroke study by submitting a data package including three month follow-up data on the final dose cohort in the PISCES study to the UK regulatory authorities in early July and, assuming approvals are granted, expects to commence recruitment into the Phase II study shortly thereafter. The PISCES study is the world's first fully-regulated clinical trial of a neural stem cell therapy for disabled stroke patients. Stroke is the third largest cause of death and the single largest cause of adult disability in the developed world. The trial is being conducted at the Institute of Neurological Sciences, Southern General Hospital, Greater Glasgow and Clyde NHS Board.
