Short Leg Rotated Pelvis Experiment

Kick off one shoe, heel, or sandal to experience the pelvis rotation caused by a short leg – it’s not magic.

Short Leg Rotated Pelvis Experiment

Experiment. SCIENCE written above assorted books, pens box, apple and mug with science doodles on chalkboard background.

Now stand up and make sure to lock both knees.

Did you feel the pelvis rotate?

How about what’s happening above the pelvis?

Notice how the mid-body and head compensate?

It may be slight since most short leg unleveling is measured in millimeters.

Regardless the size of the unleveling, when present it causes problems and the unleveling cannot be ignored!

NOTE: the short leg rotated pelvis experiment will force pelvic rotation to the extent of what’s under one foot. In other words, thick rubber sole, lots of rotation; thin flip-flop, much less pronounced.  

Can’t quite feel it happening?

Do it again & again until you do because it’s happening!

Experiment. SCIENCE written above assorted books, pens box, apple and mug with science doodles on chalkboard background.

Here’s the Science:

“Standing orthoradiography of the lumbar spine, the hip and knee joints revealed a lateral lumbar curve of 5-22° (mean=9·0°, s.d.=4·2°) secondary to leg length inequality in 186 or 64·6% of 288 consecutive patients…”

“The curvature was generally coupled with an axial rotation of the vertebrae moving the spinous processes toward the concavity, as well as with an opposite rotation of the pelvis (r=+0·77), which were calculated to result in a significant torsional stress on the L5-S1 segment.”  (emphasis ours)

 

70% of cases will demonstrate anterior pelvic rotation to the short leg side.

-Short Leg Equals Rotated Pelvis-

So, when we hear how a physical therapist, Pilates instructor, friend or relative… is working to help correct a short leg AND the leg is remains short…

we say “HOLD UP!”

-Two Reasons WHY- 

The First REASON is that the short leg may NOT be functional.

When Functional, treatment results are long-term. 

In other words, the short leg does not keep coming back. 

For example, if you’ve been under physical therapy for months and still have that short leg – NOT Functional.

And, there’s a huge difference between the two!!!

The Second REASON is that the short leg IS structural. 

In the case of a Structural short leg, the bones are NOT the same length on each side.

Measured by x-ray, standing with the knees locked, the structural short leg becomes obvious.

Short leg equals rotated pelvis – End of Story!
