    “Upload” more Brain Power? Is this the future of Stroke Rehab/Recovery ? 

    While researching emerging technologies for brain recovery as part of my new book, I started following the work that the MIT Media Lab is doing especially the work of Ed Boyden a biological engineer and brain and cognitive scientist.   If you have the time go watch the video he did for TED below, this is really interesting work.

    Some of the concepts in this video could push the envelope a bit and change how we feel about what age the brain fully develops and how we can perhaps some day “upload” more brain function to ward off decline and perhaps correct insults.

    By the way, if you took our poll and  just want the simple wiki answer to the brain development poll from a previous post then here it is:

    Answer:
    Scientists say that the brain is fully developed and matured in the late teens or early 20′s, depending on the individual. The average would be 21.

    By the Way:

    I Just learned that the University of Rhode Island is hosting an upcoming Honors Colloquium beginning later this month called “Are You Ready for the Future?“  Go to http://www.uri.edu/hc to learn more.  Ed Boyden is one of the invited guests.  If you aren’t planning to travel to Little Rhody you can see all the lectures as they will be streamed live and archived.    I might just make the drive back to my old school to see this one “live”.  See the schedule of events, it looks good.

    Exercise Guidelines for PFO Patients Needed 

     

    Know-stroke.org-Exercise Guidelines for PFO Patients Needed

     

    The PFO Research Foundation recently met in Washington, DC for its first PFO Summit.  I attended the event and was hoping for both practical and selfish reasons to get some clarity on exercise guidelines from some of the world’s top authorities on PFO.  Instead, what I learned in one of the breakout sessions aimed at developing better guideline documents and educational materials for patients with PFO disorders is that we have a great deal more work to do to get better patient information out there.  I reference a recent post to my blog from Sept. 28, 2010, at know-stroke.org to illustrate this point:

    “I just found out I have a PFO after a cerebellar stroke and ministroke in 27 months. I am 45. Should I be scared to do cardio, how much, how long, what should I avoid? Thanks Dave, I appreciate reading something from someone who seems a lot like me.”

    What should this person do?  Known PFO, positive TIA/stroke and would like to continue exercising/working out.  Is cardio fine?  Are weights OK?  What about swimming?  Climbing at altitude?  Diving?  We know these situations may present increased risk but where do you draw the line?

    Patients are turning to the web and patient forums for guidance clearly because they are not getting answers from their physicians or device manufacturers.  It’s simply not enough to tell patients “you can’t avoid the valsalva maneuver*” in daily life.  No kidding doc, really?  Is that the best advice we can give?

    I learned “off the record” after running a marathon that perhaps (running long distances) was not the best decision for me “down the road” with a PFO occluder on board.   This inside information was shared with me by a physician recently after my primary cardiac physician had cleared me and stated after more than one year post PFO closure “if my legs could carry me that far and my brain was crazy enough to talk my body into 26.2 miles then my heart would be fine”.  OK, so, what is safe?  What should PFO patients be doing for exercise  (or not doing) 1-3 weeks after closure?  How about after 6 weeks?  What is really so special about 6 weeks?  Why not 1 year (or more)?  Should every occluder device have its own post-op protocol based upon the design?  Perhaps.   What about exercise guidelines for known PFO/stroke confirmed without closure like the recent post on my blog I illustrated above.  What about known PFO, no stroke, no closure but enrolled in clinical trial related to migraines?  What about guidelines for that same patient sent home on meds or  following sham closure procedure.  Follow me?

    [Personal Sidebar] I had contacted the device manufacturer that built my heart plug several years ago after I had PFO closure.   I asked them, -NO-I challenged them to get their patient education website completed and build a useful patient resource to assist patients that were in my shoes.  That was well over 3 years ago.  The result: Still no website for patient education.  Nothing.  I’m still waiting…

    Who’s to Blame??

    Blame the FDA, insurance companies, poor clinical trial enrollment, whatever excuse we want to make, this is certainly not “best medical practice”, it is not acceptable and is in fact poor medical practice. As a practicing physical therapist, if I sent someone home after a total hip replacement and didn’t remind them that there were clear post operative hip precautions that they should be aware of following their procedure (and based upon the technique and specific device they had implanted in their body), I could be fired and sued if they went home and blew out their hip because I didn’t educate them.  That is simply part of my job!  Why are heart plugs different?  The last time I checked they were still being inserted directly in the center of our most vital organ.

    “Patients can’t continue to afford to be the pigs here.  Patients are literally putting their “hearts on the line” and deserve so much better.  When I ran the Boston Marathon in 2009  I didn’t recall any pigs passing me with a clinical trial advertisement on their bib.”-DP Dansereau

    I certainly hope this post serves as a challenge to industry and physicians to be more responsible and get our collective acts together to set things straight for patients.  At least that is why I continue to write this blog, and yes, industry, this blog creation was and remains my direct response to your failure to step up and do something.  Truth is, I write most of my content on lunch breaks and late on Friday evenings after my responsibilities as a dad and business owner are complete. (This is at least my excuse why I frequently have typos in my posts.)  I write this blog because in some way it helps patients ask more educated questions and hopefully make their medical care takers stay on their toes, at least that’s what  I’ve been told.  I have no financial disclosures to report, don’t know any venture capitalists, and have no potential gain if PFO closure proves to be a slam dunk for stroke prevention or migraine relief.  I just own the peace of mind that I did something.  Now, I must get back to my patients, and then perhaps go out for a run later this evening when I get done here at work.

    Or should I ?   Who knows?   I’d love for you to comment here if you do….

    Better Exercise Guidelines for PFO Patients

    By David P Dansereau

    For know-stroke.org

    * Valsalva maneuver: A maneuver in which a person tries to exhale forcibly with a closed windpipe so that no air exits through the mouth or nose as, for example, in strenuous coughing, straining during a bowel movement, or lifting a heavy weight. The Valsalva maneuver impedes the return of venous blood to the heart.

      My question exactly …. At my one-month post-op appt. today my cardiologist said I should wait another two weeks before I start back to my cardio regime (running, cardio classes, swimming, etc.). Initially, he said four weeks. The question is when does a person reach the point where there are no recommended restrictions for exercise?

    • David 7:57 pm on November 11, 2010 Permalink | Reply

      That is the million dollar PFO/exercise question Pam. I wish I had the answer for you but as you can see even your doc seemed a bit vague with your post-op exercise instructions. I did not go back to unrestricted exercise for almost a year following closure. I was working on restoring balance and stability and these are not exactly “high risk” activities. Because my post exercise instructions were also not that clear I went by what I learned in PT school about the rate of tissues healing. While soft tissue surrounding a joint may not be the same as cardiac tissue I did play it safe knowing that soft tissue injuries “or healing” need 12-18 weeks to fully “remodel”. In PT there is then a re-strengthening phase that goes in stages that often takes up to a full year to return a joint to full strength prior to when it was damaged. While this may be the extreme example, I decided I was not going to take a chance and blow my recovery with my most vital organ at risk. Those recovery guidelines I just outlined were my own and pls. take them for what they are worth but having that knowledge at least helped guide my own healing, both in my heart and my mind. I know you’ll also find out on the web other extreme examples where physicians are telling their patients it is safe to go running day 2-post-op. That’s why the medical community involved with PFO closure needs to do better educating and why we hope to get better guidelines established through our patient led group at PFOresearch.org
      Thank you for your question.

      David,
      I too am in the medical profession, as a retired, R.N. No doubt, it has helped me immensely to be able to ask questions, logical ones, of what to expect post closure. I too, have been met with the same, ‘you’ll be able to go back to work in a few days with a few limitations, like lifting and the like…’ or, ‘you’ll need to take it easy for awhile…’ all the way to, ‘you reallly should not lift anything above 3 pounds for 4-6 weeks…’
      Then of course I was told, by my cardiologisit, of a 10 year old who had the PFO closure done, who, apparently felt well enough to shoot some baskets on day 3, and his device ‘popped out’ and embolized, and he died immediately… And, of course, he told me about the woman, who had her every 6 month echo for 1.5 years, then between the 1.5 and 2 year check up she had a stroke, and the echo revealed a huge scarring tissue in her atrium around/over and behind the implant. She had to have open heart to save her and get teh implant out!
      On teh PFO research foundation FB page, I read of patients with weekly migraines, marked chest pain for 1+ year post closure, and I am left with a sinking feeling…am I a desperate guinea pig?
      ‘If’ the >13 lesions on my brain are in fact stroke sites, why did the 1st neuologist phoo phoo the then 4 lesions as, ‘normal to have one for every decade of life’ (I was 42), one year later, and now 13+ lesions, I was told by my 3rd neurologist, ‘it could be MS, but, because you have a PFO, we have to make sure it is not strokes, from the PFO.’ Then neurologist #4 & #5, concurred, I am having strokes, likey passing emboli through my PFO…’
      I am presently scheduled for Feb. 11 for investigational cath as I am scared of the implant, and want the doctor to first look, and investigate teh secondary shunts, fix them, and then come out and reprot to me just how bad that PFO really looks. If he says, it is huge! well, i guess I will be scheduling a 2nd cath, for closure. (?)
      But, what does ‘return to work’ mean, when you are a mother of 5 young children, still home. (I can’t ‘leave’ work) My toddler will still have emergencies that need rescue. And, if doctors do not give explicit protocol for family members to have the right expectations, then everyone will think wife/mom should be back to business as usual. We have around 10-15 loads of laundry around here weekly. Is pouring a gallon of milk (8lbs) for my toddler, over the weight limit? Can i lift from above my head, and, if so, how heavy should it be? If I catch my kids throw up flu bug, do I need immediate phenergan to make sure I don’t put too much pressure on my new implant,due to massive valsalvaing? should I be in cardiac rehab? Stroke Rehab? What do I report? Should I be working with a PT to gauge my activity tolerance? the days are ticking down to Cath Day…and somehow I am suppose to submit to this implant being put in me, without knowing these answers. And, if you are being told you have had >13 strokes in the last 15 months, do you delay the procedure? And, ‘if’ I have really had >13 strokes, why am I not in stroke rehab?

    Time is Brain (and we still need to know more about PFO and Stroke…) 

    know-stroke.org

    Know-Stroke.org

    As you might be aware May is Stroke Awareness Month.

    I hope that you take some time this month to review and advance your knowledge on stroke!  To keep up to date, I just finished viewing a replay on the Rhode Island Hospital (Providence) website where they created a stroke e-presentation for the EMS Community featuring Dr. Edward Feldmann, MD former Director of the Stroke Center.
    If you’d like to review your knowledge of stroke Dr. Feldman’s presentation is worth your time.  Remember, especially this month, “Time is Brain”.
    I thought it was interesting that during his presentation Dr. Feldman noted while covering the neuro floor at the hospital recently he witnessed at least “12 or so” of the stroke patients on the floor were younger than 50 years old.
    [Personal Sidebar] Would be curious how many of those young stroke survivors under 50 may have had a PFO, but PFO  was not mentioned in the presentation. We still have work to do.

    Please feel free to share this presentation with your partners, work associates, family and friends.  If you don’t have time to watch the presentation now, here’s a quick review from the presentation on  how to recognize a stroke and act “FAST”.
    Know-Stroke Act FAST

    Act FAST and call 911

    Either way, be sure you Know Stroke !

    Do stroke victims work harder using new gaming technologies? 

    Research Update:

    Recently I had the chance to try out the Nintendo Wii Fit system for the first time. I’ll plan to follow up with a post later on my thoughts on this device as a stroke rehabilitation tool. Since using the system and forming my own opinion, I wanted to research how other therapists might be embracing this emerging technology. In the short time I have been following this Wii-habilitation” movement I have to say I receive 4-5 google alerts each day with updates from both therapy and gaming blogs using the term wii-habilitation. This post from a CNET News Blog caught my eye because it showed how cutting edge rehabilitation centers around the country are starting to receive research grants to study how effective Wii and other gaming devices can be to help stroke survivors retrain lost motor skills and regain function.

    This from the CNET Blog :

    “And now researchers at the University of South Carolina are turning the trend into a research project that will study exactly how well the Wii and other games can help stroke victims recover motor skills and overcome a fear of falling after their trauma.

    The research is part of a new $2 million grant from philanthropic group the Robert Wood Johnson Foundation, which will be administered by the University of California Santa Barbara’s Health Games Research Center. On Thursday, the two organizations announced that 12 different research projects, including USC’s Wii project, will receive funding of up to $200,000 each to study how interactive games can be used to improve public health and the health care profession. The studies will last between one to two years.”
