We need to keep in mind that there is no pain signal coming in from the periphery.
Pain is not an input. It is simply (and complexly?!) a nerve being stimulated, sending an action potential up to the spinal cord and then brain, where the brain interprets those signals.
…and that’s where it get’s sticky… because what is Continue reading
I had chronic low back pain.
The first incident was years prior in college: randomly getting up from a nap on the couch (college!) and my back grabbed me and put me on the floor. 9/10 P! Never happened before, so I just lay there for a bit and crawled around until I could relax enough to stand.
Fast forward: after college I would try to Continue reading
In reading Spencer’s recent posts (particularly Part 2, but also Part 1) I am struck by an interesting theme. The information was there. It was just somehow interpreted wrong and dispersed wrong, or received wrong… like a game of telephone.
Spencer mentions that the IASP definition of pain “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage” is clearly presented in education. Since it is there all along… how does it get lost in translation? Can we blame the Continue reading
Nociception is subject to all the truths and flaws of any other input system.
Patients never have this view, since their pain has been described to them in terms of body parts and structures. However, the tissue is as important in pain as the eyeball is in what we see.
This past week’s viral internet subject is a great example of all that (Black ‘n’ Blue dress). Vision is simply our brain’s decision based on the information available to it, including, but not limited to, the light waves of objects. The eye itself is simply an Continue reading

If you’ve been anywhere near a peer reviewed Journal in the past years you are well aware that the idea of positions equaling pain has been fully debunked (Eyal Lederman, Greg Lehman, Todd Hargrove, SportsDietPain ) The concept of poor posture = pain is still widely used (I won’t even list here…) but it is not backed-up by pain science.
Or is it?
Poor posture can indeed increase the chances of pain. Now, posture is a state. An act. A positioning of one’s self. Psychology tells us that if we stand tall with a smile then we will feel more powerful and be a more agreeable person.
“Kahneman writes about test subjects given a pencil. In one set of tests the subjects are asked to hold the pencil between their teeth horizontally. In another the same subjects are asked to purse their lips around the eraser end of the pencil. Then the subjects were shown cartoons from Gary Larson’s The Far Side. Those in the first group, with the horizontal pencil, were more likely to find the images funny than the second group, with their lips pursed around the pencil’s eraser end. What’s going on? The researchers concluded that clenching the pencil horizontally yielded a “smile,” with cheeks pinched back and the outer edges of the mouth turned upwards. Those holding the pencil’s eraser end in their mouths yielded a “frown.”” – The Observer
So our body position affects our perception of reality. And pain is perception of stimuli as well.
It makes us feel better to have “correct” posture. (recommendation: spend 20 min with this TEDtalk)
Music has the ability to go deep and move us. We have all been on the dance floor when “our jam” comes on and you just have to pick up the pace and move with the music. You had no choice. Contemplate that for a moment, why is that? Why does it feel so good to match your movements to the beat? Let’s dive in…
We will use the research study: Interactions between auditory and dorsal premotor cortex during
synchronization to musical rhythms, by Joyce L. Chen, Robert J. Zatorre, Virginia B. Penhune, 2006 in NeuroImage to explain the premise. (open source!)
To start off- some background information on Continue reading
Have you ever asked someone where they are from? Sure, you have. Have you noticed a breadth of answers in terms of history time-line?
For example: Some might say
- “Oh, I’m from Hillcrest Neighborhood” (immediate History)
- “I’m from Virginia” (current History)
- “I grew up in Boston” (Childhood / Distant History)
- “My family-line is from Poland” (Distant History)
- etc… and on.
How far back do we normally go? Perhaps it depends on who is asking the question, and what the context of the conversation is about. Continue reading
I just recently finished 8 weeks at an excellent neuro-rehab facility. During my time there I presented an inservice proposing visual dominance as an indication for mirror therapy, but as I suggested during my talk–I think this sensory preference could go much further than indicating the use of a mirror during stroke rehab if we take advantage of it.
