Pevlis Evaluation And Adjustment

Question 1

What is Piedau’s test?

Answer 1

Looking for bilaterally even separation of the PSIS and sacral apex during forward flexion —>

Ilium flexion
Sacral counternutation

The sacral base moves posteriorly and the apex moves anteriorly

Question 2

What results make us suspect dysfunction when using Piedau’s?

Answer 2

We suspect dysfunction on the side where the PSIS moves MORE because the entire ilium is moving to make up for lack of SI motion

Question 3

Leg Length Eval:
If discrepancy and we bend the knees to 90 degrees what does it mean if:

• LLI disappears
• LLI remains

Answer 3

LLI that disappears is either functional or due to the femur

LLI that persists is tib/fib inequality

Question 4

Leg Length Eval:

Allis test
Sit up test

What do they mean?

Answer 4

Allis - bend knees to 90 degrees. If one is higher or in front of the other, there is likely a structural inequality in femur or tibia.

Sit up test:

• leg LENGTHENS on the PI side
• leg SHORTENS on the AS side
