OK. So a gunman goes into a nursing home and kills 7 nursing home patients. What a coward. "The slain patients ranged in age from 78 to 98." Whats next? "I'm going to blow away people in hospice!"
The killer was 45. He was ..."armed with a rifle, a shotgun and other weapons." I mean, if you're in that much of a rage, wouldn't you look for some sort of challenge? What could the possible motivation be?
"My knee's been acting up. I need someone slower than me!"
I've worked in nursing homes. My wife is a PT in one that looks almost exactly like the one that was attacked. This one, in NC, was focused on folks with Alzheimer's. Cowardly, weird, sad, the end.

This is the history of stroke recovery. This is a perspective that is uniquely my own; a simplified version of a narrative built up in my head over the years. It will be in multiple parts. How many parts? Well, answering that question would involve fancy-underpancy planning, to which I have an aversion.
Histories are important because they tie people, which is what people like to think about (generally), to events. In this case “events” refers to the ambling from there to here; from not knowing what a stroke was to understanding quite a bit about not only stroke, but recovery, too. Like most of our collective story, it all starts with cavemen… I wrote an article about it. And there is a chapter in my book, about how cavemen might have handled stroke. (One editor suggested I change every “caveman” to “caveperson” which I didn’t do because really?)
STROKE RECOVERY, THE EARLY YEARS
Anyway…so it starts with our ancestors that lived in caves. More accurately, it wasn’t about where they lived, but how much they moved. They moved in hunter-gatherer tribes. These were small bands of individuals, begat (!) from our common Mom (or “CoMom”), Lucy. These folks walked and walked and walked, always on two legs. Two leg walking was good because allowed us to see more stuff (because we were taller), and use our hands to carry junk (because they weren’t doing anything else and we feared they’d dwindle into tiny T-Rex-style flippers with claws) and keep us cool in the Kalahari heat (because standing provides less surface area). As you can see, I’m no anthropomorficologist, but this is my story, so I’ll filter the facts the way I see fit thank you.
So we walked and roamed and found stuff and ate it. We were also really good at hunting because, although we're not the best sprinters, we were great at distances running and walking. So we would run after edible beasts at our own two-legged pace. Once we caught up to them, it was a 2 fer 1; They were too tired to run and/or fight, and they were so hot they were already half-cooked!
If an individual had a stroke, there would have been a general feeling that some sort of higher power was pissed. It was probably an omniscient female deity, because all of our deities were female back then. And no wonder. There is now a belief that our numbers shrunk to just a few thousand at one point, probably because of a severe drought. So anything that could give birth would be seen as (as Kung-Foo Panda would say) awesome and attractive. So once the ever-pregnant She-God decided you needed a smack-down, a smack-down smacked upon thee. And if She chose, she would give you a "smack upside the head", which is what cavefolk used to call a stroke. And as I mentioned in my article, there would have been a serious effort to get the stroke survivor on their feet and the “therapy” would have been focused and ferocious. And it would be directed not by a therapist, but by survival instinct. This instinct knows no rational bounds, and no stinkin’ stroke was going to stop us from surviving. The survival instinct is just not something we access much any more.
We’re now in the “fat and happy” part of evolution (anthropomorficologically speaking).
This is how I've put it earlier:
Intensity and frequency of post-stroke rehabilitation is one of the hot topics among stroke researchers. Research has shown that patients spend as little as 13 percent of their day (8 a.m. to 5 p.m.) involved in rehabilitation efforts within the first 14 days after the stroke while spending 78 percent of their time in bed or sitting next to their bed. Might the ability of our evolutionary cousins to couple their huge capacity for physical work with the natural demands of life in a hunter-gatherer tribe have some lessons for today's stroke survivor?
Modern-day researchers believe there are lessons. This belief is reflected in so many of the newer recovery options that involve so many more hours of work. "Intensive therapy" and "over-challenge" is the way researchers put it. We’re trying to get stroke survivors, by hook or by trick, to access their inner survival instinct.
PART II: THE GREEKS ADD THEIR 2¢
And that’s the way it stood for 3 mill plus years. You’d get a stroke and you’d fight like hell to get back to where you once belonged.
Hippocrates showed up 2400 YEARS AGO and did something remarkable: he defined stroke. He wrote about stroke and aphasia and TIA’s (transient or “mini” strokes). He made up a word for it: Plesso. Which meant “Slapped upside the head by God.” 250 years later another Greek doc, Galen, said that he thought stroke was “thick and dense humors” built up in the ventricles of the brain. Which, you know, is a pretty good guess that sounds a bit like an ischemic (block) stroke. Galen was pretty interesting. He was the personal physician to Marcus Aurelius and Commodus, two of the characters in one of my fav flicks, Gladiator.
Then nada for a thousand years or so and then the Germans came up with the word “strAcian” whch loosely meant “bonked on the head with a kilo of Spätzle.” The derivative of this word is stroke. But Hippocrates’sess’s word, Plesso was the basis for the word apoplexy, which you still hear on old Andy Griffin episodes.
PART II: THE CLASS OF 1950
Working in the early 1900’s, Sir Charles Sherrington was a colossus of all things neurological. Sherrington was a Nobel winner (1932, functions of neurons). It is hard to explain how ginormous this guy was. His ideas on what drove human movement were law. One of his hypotheses was called reflexology. Reflexology basically said that all control over muscles came from the spinal cord, and was just a series of reflexes. The brain got involved, sure, but just a filter for the prime mover: reflexes.
“Sherringtonian reflexology” was adopted by many of the most influential physical therapists that ever lived. Sherrington had a great influence on PT and OT as it related to stroke. His influence was especially strong from the 1950's to the 1990's. From the '50s to the '70s was when physical and occupational therapy was just beginning to address stroke-specific therapies. The problem is they had inaccurate tests, so it was difficult to determine if what they were doing was actually working.
They had another problem, as well. Some therapists took Sherrington’s reflexology and smeared it on every aspect of stroke recovery like a kid with hot toast and runny peanut butter. For his part, Sherrington disavowed the idea that it was all about reflexes (and accepted that movement was controlled and learned in the brain) by the late '40s. Hey, he was a bright guy and a true scientist; if new evidence comes to light, you change. If you want definitive answers, look to religion.
The problem was that a few influential therapists, most forcefully Berta Bobath, never got the memo that it is in the brain, not the spinal cord, that control resides. In her book Adult Hemiplegia (1970), Bobath began writing about, teaching and generally espousing that it was all about reflexes—which come from the spinal cord. Bobath also believed the way survivors naturally move after stroke was so bad that therapists should not allow the movement to take place. The way that survivors move is called synergistic movement. It is still believed, by many therapists influenced by Bobath to be movement so evil that Bobath and her followers set about separating stroke survivors from the only movement they had! Fast forward to 2000 and the Bobath Center (sorry, Centre), the British seat of all things Bobath. They issued the following statement: “While certain activities are not encouraged in some cases, the idea of stopping a client from moving, especially if they are motivated to do so, cannot be supported on financial, moral or scientific grounds.” But it has been difficult to let go of a core concept that had been a cornerstone of the Bobath approach for decades. For example, in 2008 an article (p.133) defending the Bobath approach wrote, "Abnormal/atypical patterns of coordination need to be suppressed and unwanted movements controlled..." Under this premise, you'd need someone with you during the entire arc of recovery. Otherwise you might move wrong.
Stroke survivors need the ugly movement to get to good movement. Imagine yelling to a baby, “Look at you, you duck-footed fool! Bend your knees and stop falling!!” Imagine telling someone who is learning a language (or instrument, or anything), “Stop making mistakes!” Learning requires mistakes. Mistakes corrected are learning.
Bobath’s therapy, called neurodevelopmental technique (NDT) is still very popular, but it’s not very scientifically-based. (See Here. Here. Here. Here. And a great non-scientific discussion here). My suggestion is to avoid therapists who say I’m a “this-based therapist, or a that-based therapists.” Instead, look for therapists who say something along the lines of, “I’m an evidence-based therapist. I consider the best science and meld it with my clinical experience.”
Weirdly, a contemporary of Bobath, Signe Brunnström, who also published her best known work in 1970, was clear right out the box: Use any movement, synergistic or not. We now know we need to encourage “ugly” movement to rewire the brain neuroplastically. Not only that, but Brunnström suggested really forward thinking concepts that are accepted by stroke-recovery researchers all over the world. Among them were Brunnström’s “6 stages of recovery.” Despite the fact that Hippocrates had defined stroke 2400 years before, Brunnström was the first person to fully delineate the predictable steps towards recovery. It turns out that her stages of recovery are so accurate that they can be correlated with brain-scanning technology like MRI (see Here and here). Just like Einstein, Brunnström predicted stuff and then waited for the world to catch up. The bad news was that Bobath’s NDT was wildly more popular than Brunnström’s techniques. Why was Bobath more popular than Brunnström? It may have been a simple issue of duration of message. Brunnström was diagnosed with Alzheimers and began to live in a nursing home in 1976. Bobath died in 1991.
PART III: TAUB BUCKS THE POWERS THAT BE
Edward Taub represents the full-on separation from the “reflexes rule” argument. He showed, through animal testing that, even when you get rid of reflexes (with an operation that cuts nerves to the spinal cord) you can still learn new movement. Repetitive practice movement drives changes in the brain. Those changes lead to better movement. This ushered in constraint-induced therapy, and other ideas that were as simple as pie: repeat a movement and that movement will get better.
Just like the cavefolk did.
Well duh. And it only took us forever to figure out what we already knew.
My daughter wants to to play soccer now. The End.

ADDENDUM: 2.11.14: THIS RECORDING IS NO LONGER AVAILABLE-FOR SOME REASON :<

"I know a rock star. His name is Dave Grohl. He was the drummer in the band Nirvana and now heads the Foo Fighters.
I haven't talked to him since a thrilling evening in Atlanta backstage at a Nirvana concert in 1994. But I know how he got to be an amazing drummer. And it wasn't easy. First, let me tell you why his story has everything to do with (stroke recovery)."
Play me until you get blisters
I'm a drummer as well. Drumming is interesting because it hits (heh heh) on so many leading-edge topics in stroke recovery. One is cognitive. It turns out that there is a company that uses keeping a beat to drive better cognitive recovery. Drumming is also inherently bilateral (left, right); and bilateral training is a hot stroke-recovery idea. It may even help with the only long word I remember from school, dysdiadokinesia, an inability to do alternating (bilateral) movements after brain injury. Why did I remember it? Dude. I'm a drummer. And this brings up the next point: use what you love to drive recovery. The more intensely you love doing something the less it becomes therapy and the more it is just plain fun. Whats the old saying, "If you love your work, its not work."

How is the typical therapist supposed to find the articles and have the time to sort the whole article out? I have no idea. And it sucks because it has consequences on the treatment of stroke survivors. I think that there should be a law that says that if you are doing any sort of research on human participants (subjects) that there should be a one-page explanation, in clear, simple and plain language that everyone can understand, what the intervention was, and what its clinical application is.
This photo is my son Jesse’s reaction when I told him about how researchers are trying to hoard all the thinkology.
