Most people think of their jaw as a relatively benign, unimportant joint. That could not be further from the truth! The jaw itself is a relatively small joint, but it has five powerful muscles attached to it. Including all of the muscles, the jaw takes up almost half of the head's surface anatomy.
When there’s a pathology with the jaw, it doesn’t just manifest in the jaw. Certainly, you’ll get a decreased range of motion in the jaw (making it difficult to eat a large hamburger), but you might also develop headaches, neck pain, and secondary migraines.
When a first-bike-buyer walks into the shop, they've usually got a checklist that looks a bit like this:
-Comfortable/natural to ride
- Bag to carry your laptop & suit to work
- Lots of space to put lights so that you're visible at night
- Tough tyres so that that you don't have to repair punctures every week
- Costs less than $500
All are excellent characteristics on a bicycle, but that checklist is missing one critical point: how are you going to avoid repetitive strain injuries (RSI) on the bike?
This Sunday is the first time since I was in university that I didn't run in the Melbourne Marathon. The reason that I didn't is because I was working with some other SYSSM practitioners on the elite runners as they crossed the finish line, which was a great experience, but I was definitely jealous of the 30,000 runners that did compete this year.
Of all the elite runners that we treated on Sunday morning, and all the amateur runners I've treated on Monday and Tuesday, ALL of them had tight calves.
