Soccer Injury Prevention: Hamstring Assessment Part 2

 

In Part 1, I briefly explained the anatomy of the hamstring musculature and how pelvic position can affect it’s function. I would highly recommend reviewing part one here before part 2.  For part 2, I wanted to take the time to provide a few assessments that you can use with your soccer athlete’s to see a variety of important issues.

#1 Active Straight Leg Raise Assessment

As far as I know, the active straight leg raise assessment (ASLR) started with the Functional Movement Screen (FMS).   The ASLR is more than a hamstring length test.  It also looks at…

Timing of the Inner Core Subsystem (core stability)

Leg separation (hip flexion on up leg/hip extension on down leg)

Superficial Back Line extensiblility

connected muscle tissue from foot to skull

Not making sense? Watch this video

The standard or goal for ASLR is symmetrical 2’s.  If the athlete has this we should be good to go with training.  Often times, we see an asymmetry from left to ride sides even when the scores are 2’s.  In the FMS this is fine as long as it is within range of the screen.  Taking the PRI courses allowed us to dig deeper down the rabbit hole to see why this may occur.  The right ASLR will have more than the left because of the position of the pelvis in a Left AIC pattern (left hemi-pelvis situated in a state of anterior tilt and forward rotation to the right).  Simply, because the pelvis on the right is oriented in a state of posterior pelvic tilt (the opposite of the left side), it allows the right leg to go farther up.  

What’s the big deal?

After we have done the two basic assessments (adduction drop  & extension drop test) and know they are in a L AIC pattern (if you are not familiar, just realize that we SHOULD see a higher right ASLR compared to left).  A major issue arises when the left side is longer.  This indicates (if in a L AIC pattern) that an already stretched out left hamstring is even more lengthened than it should and one of the reason we can see many hamstring pulls or issues higher up on the left.

Wait till part 3 where there will be a video of the adduction drop and extension drop tests as well as re-positioning exercises to facilitate the left hamstring (if needed) and bring the pelvis back to neutrality.

 

Cheers,

Matt
