BJJ took a backseat for me after training regularly during my bachelor's degree. It stayed on the back burner as I worked on my master's degree but my schedule has normalized enough to allow me to resume training. My sports medicine breadth of knowledge has grown and advanced while my BJJ was placed on hold, and because of that I feel that I have a expanded view on the biomechanics of the sport that I didn't necessarily have previously.
Specifically, I am going to touch briefly on a bit of injury prevention for anyone out there that may be into BJJ or for those of you that may treat people that participate in BJJ (actually this stuff applies to everybody not just BJJ guys). Nevertheless, this post is definitely geared more for the BJJ practitioner and not the clinicians out there...this may not even be new information for those who have visited this blog before.
While I am not somebody that you should go to for submission or any BJJ advice for that matter...I feel that I can give some good insight to help you stay on the mats. Specifically, when I was training I often saw a lot of people struggle with shoulder injuries. In fact, traumatic shoulder dislocations and subluxations were more prevalent than one might assume. Perhaps one wouldn't be surprised considering this is a sport where people enjoy catching each other in joint locks and submission-holds that work by forcibly placing one another's joints at their respective end ranges of motion. So when it comes to a sport where we are already pushing the limits with our body (within reason) then we need to ensure that we are not already at risk of damaging ourselves or our training partners.

1) Upper Extremity Pattern #1
|What does this shoulder position look like?|
|Looks a lot like our test above...If you can't easily put your own arm here, how do you expect it to feel when does it for you?|
#2) Upper Extremity Pattern #2
For this test you need adequate shoulder external rotation, shoulder abduction, shoulder flexion, and elbow flexion on top of thoracic extension/rotation as well. To pass this test you must be able to reach your fingers to your contralateral scapula. Where at on the scapula? The midpoint of the spine of your scapula is our targeted destination. However, you need to look for symmetry of movement from side to side, check out how much effort is required, and if there is any deviation of posture to achieve this position. Additionally, a person is not allowed to "crawl" their hands up or down their back for either test. It has to be done with one smooth motion and without "warming" up.
|This is not the same as Upper Extremity Pattern #2 but it IS the same. Get it?|
So what do you do if fail these tests? That is a debate for another day but you honestly need more information. However, if you want to use a trial-and-error method then all you need to do is try something out like flopping on a foam roller, lacrosse ball, or getting a massage and seeing if there is a difference afterwards. How will you know if there is a difference? Retest! Mobility may work may not fix this so don't assume that is what it is! It could just as easily be a motor control or stability issue. Here is a sample of what breaking down one of these tests looks like.
While these tests are far from all-inclusive or the be-all-end-all they are a great starting place to screen or assess for potential risk of injury. If you can do this it doesn't mean you won't injury your shoulder or that you are 100% good to go but if you can't I do know that you deviate from normal into abnormal. Abnormal or dysfunction in my book is the same as pathological and may lead to future injury down the road. Get to work on bullet-proofing your shoulders before it is too late and you are under the scalpel.
