At the judo club, a PA (I think? doctor, maybe?) who works in sports physical therapy was doing these movement screenings for people. Mine was this morning. I vaguely imagined it would be like the kinds of things you do at a physical, but it was kind of intense!
He attached these force measurement devices to various limbs, then asked me to pull in various directions as hard as I could. It was difficult, but informative. I found out my right shoulder stabilizers are weak, which might be because I subluxated it back in the '00s.
He showed me an exercise I could do to help with it with a three-pound weight in which you lie on your side, pin your elbow to your ribs, hold the weight out perpendicularly, then lift it up toward the ceiling. A set of eight was barely doable.
I also have weaker than average quads (I don't know exactly who's being averaged here) and generally my right leg is weaker than my left, even though I'm right-handed.
There was also some standing on one foot and reaching as far as you can in three directions. I'm slightly above average in those tests.
Then, some standing on a step and reaching down to the floor repeatedly with one foot, and finally, reaching to the side with alternating hands while in push-up position.
I'm going to get the numbers later, but already, this is really handy info. I'd say all doctors should do this, but first, we need to be able to get people to doctors without it being a huge hurdle.
