Victim in the middle! AKA the knee

After receiving a request to post a video on the knee on my youtube channel, I thought I would comment on a common theme in knee injuries.  To understand dysfunctions in the knee we first have to understand how the knee is made.  First and foremost the knee is a hinge joint.  Meaning just like a hinge on a door it likes to move primarily in one plane being forward and backward.  The knee is happy moving as a hinge joint but degenerates and suffers injuries when asked to move side to side or rotate.

So… since the knee can’t significantly move side to side or rotate on it’s own because of how the bones are made then what introduces pathological motion of rotation and side to side movement?  Well, it’s not the knee that’s doing it.

The knee is RARELY the problem with knee problems.

Look to the neighbors of the knee.  The foot and hip.  The foot and hip have the ability to greatly move side to side and rotate.  Could the foot be making the knee move side to side too much?  YES.  Could the hip be making the knee move side to side too much?  YES.  Could the hip and foot be working to destroy the knee?  YES.  Can the knee create these motions by itself?  No.

Quit blaming the knee while it’s screaming for help and look at the neighbors above and below.

Secret ingredient for fall prevention

The title of this article is in reference to an often overlooked aspect considering fall prevention.  The focus of this post is POWER.  Power = force x velocity.  Velocity in reference to the speed at which you are moving.  Power is essential in fall prevention by quickly recovering from a perturbation, or balance challenge.  If I trip stepping over a curb, my center of gravity (torso) will quickly travel in front of my base of support thus precipitating a fall.  Unless I can quickly recover and move my leg in front of my center of gravity I will fall.  Thus my leg must move quicker than my torso as I try to recover from the perturbation.  An essential component to fall prevention is the speed at which you can move.  Being able to orient your ‘center of gravity’ over your ‘base of support’ is essential to maintaining balance.  It is a necessity that speed is present, or the ability to move quickly, in order to orient the base of support under your center of gravity, aka your legs under your torso.

So when you are attempting to address balance please integrate speed as a variable in exercise selection

Good Luck and more to come!

Robin Hood, Movement dysfunction, and Pain

Robin Hood is a story where the hero ‘robbed from the rich to give to the poor’.  I think of movement dysfunction in the same manner.  If a hip is stiff and unable to rotate it will ‘rob’ that motion of rotation from somewhere either above or below itself.  If the hip ‘robs’ rotation from the low back then there is a high probability of creating dysfunction.  Some literature suggests disc tears happen with rotation > 5 degrees between motion segments in the low back.

Hopefully by having a general understanding of movement responsibilities in the body we can avoid the ‘Robin Hood’ scenario and avoid movement dysfunction and subsequent pain.

Best friend to the low back!

The hip can be one of the most powerful allies in helping out the low back.  The hip is one of the most mobile joints in the body allowing for a great amount of motion forward/backward, side to side, and with rotation.  The low back as in a previously posted video is made primarily for forward/backward motion.  The hip can help bear the burden of motion for side to side and with rotation.  When the hip becomes stiff it then becomes the enemy of the low back by stealing motion from the low back causing dysfunction.  Check out the latest video!

Considerations for strength and conditioning the preadolescent athlete SOCCER

Just finished a powerpoint presentation addressing coaching, training, or conditioning the young athlete (ages 5-12).  A couple of slides bias this presentation toward the sport of Soccer, but implications are applicable across the board.  Free for download without audio by clicking the following ====> youthsoccer

Hope you enjoy the information I provide and continue to be patient as I find time to build information regarding strategies to preserve, enhance, and restore movement!  Thanks!
