Learning how injuries happen can help us prevent and treat them. Unfortunately, you can’t just do a study asking people to hurt themselves on purpose… those pesky ethical committees would never approve of your brilliant study.
Then how are we supposed to collect such data? Accidentally of course!
Researchers in Germany were doing a study with soccer players performing a run and cut maneuver while being recorded with 3D motion capture and EMG (electromyography – which measures muscle activity).1
During one of the run and cut trials, one of the soccer players actually rolled their ankle by accident! It happened while all the recording equipment was running! Serendipity defined.
What did we learn?Continue Reading
As you learn more about how pain works, you’ll notice a distinction is made between ‘acute’ and ‘chronic’ pain.
What does this mean? Is it just a matter of time?
Or is there something different happening when pain persists?
It turns out to be a bit more complicated than once thought… let’s discuss!Continue Reading
I’ve received another great question from a B-Boy:
Is there a way to avoid that awkward bald spot from head spins? Do beanies help or hinder?
Good question! This is something I’ve wanted to learn more about myself.
As can be seen in the photo – I’m like the Hair Club president – “I’m also a client”.
Back in the early 1600’s, a famous philosopher and mathematician named René Descartes came up with a theory to explain pain.
This theory can be summed up by the painting to the right (created by Descartes himself): a disturbance is passed along a nerve fiber until it reaches the brain. When the brain becomes conscious of the pain signal, it somehow reacts (by moving you away from the fire, for example).
Prior to this, people believed that pain was caused by spiritual or mystical forces. With Descartes new theory, pain finally had a physical explanation.
Innumerable treatments for pain are based on this model of “pain receptors” (nerve endings) detecting damage or degeneration, and sending “pain signals” to the brain. Many people continue to think this way – including a lot of healthcare professionals.
It is thought that pain can simply be “killed” by using medications to numb pain receptors. If pain persists (becoming “chronic”), some sort of degeneration or mechanical problem must exist that continues to aggravate pain receptors, and therefore must be “corrected” through surgery.
How well does this model explain pain?
More importantly, how well do these treatments work?
