Rotary Stability

Quickly measure and calculate Movement Screens

This assessment is used to measure your stability and motor control while shifting your weight and during the crawling or climbing movement pattern considered to be an integral part of the human development pattern from childhood. Improvement in this movement pattern will increase athletic performance and resistance against injury.

Rotary Stability Protocol


The rotary stability movement evaluates pelvis, core, and shoulder girdle stability during a complex upper and lower extremity movement. This test demonstrates stabilization while performing in a transverse plane.


Screening Kit


  • Instruct the client to move into a quadruped position on the floor with a board between the hand and knees, making sure their feet perpendicular to the floor.
  • Be sure that his/her knees and feet are touching the board.
  • Instruct the client to flex their shoulder while extending the same-side hip and knee, and then immediately bring elbow to knee while remaining directly over the board.
  • Perform test on each side 3 times, if a score of 3 is not attained, instruct the client to perform the test using the opposite shoulder and knee.
  • Posterior Rocking Clearing – Instruct the client to assume quadruped position and then rock back and touching the gluteals to their heels and the chest to thighs

Rotary Stability Calculation

3 - Correct unilateral repetition
2 - Correct diagonal repetition
1 - Incorrect diagonal repetition
0 - Pain is associated while performing the movement
