This is Dr. Berg. We're going to talk about snowboarding and knee pain. Now if you are a snowboarder and you have knee pain, I'm going to walk you through two powerful techniques to reduce your pain. Typically snowboarding is a little bit safer on the knees than skiing because you have more stability because you are locking both feet into one board. But, many times when you fall the front part of the knee actually pushes forward inward right here and what that does is it injures a little ligament called the anterior cruciate ligament, that's a little ligament that prevents these two bones from going too far one way or the other. So I'm going to show you two techniques to improve that but just remember, if there is a tear see your doctor. Okay, so in this first technique we're going to basically reverse the injury by taking the knee and pulling it outward like this. Okay you're going to stretch it out and let go, pull it out and let go. We're going to repetitively do that about 20 times so you are going to need some help from someone to pull this out and basically what we are doing is we are taking the guarding mechanism that keeps it unstable and we're taking the guarding out to balance that out. So it will give the person a lot of relief. Now on the second technique we are basically going to work on the opposite muscle on the thigh on the opposite side. Now why is that? Because every time you injure one side, the opposite side takes up the slack and it does most of the compensation. So we're going to work on this muscle right here called the thigh muscle right here and as we press up into the hip, we're going to come up very slowly, feeling for little knots and we're going to massage those right out of that thigh muscle. So we're going to move a little on the outer part, up and down, back and forth until that entire thigh muscle is relaxed. Doing that will take all the guarding out of the opposite muscle and take the pressure off the knee.
