Rotary Stability Screen

Rotary Stability Screen (Raise)
Rotary Stability Screen Test (Retract)



Get on hands and knees over board (approximately 2 x 6 inch or 5 x 15 cm) with arms and thighs positioned vertically. Position feet vertically so toes rest on floor. Thumbs, knees, toes must be in contact with board.


Simultanously, reach right arm forward and extend right leg backward (ie: unilateral superman). Retract elbow and right knee until they touch directly over board. Repeat so at least two repetition have been completed without contacting floor with right arm arm or right let  with floor or board. Repeat test on other side.

If subject cannot complete movement as described within three attempts, subject should attempt modified movement: diagonal flexion and extension lift (lift and retract right arm in sync with lifting and retracting left leg).


Test administrator assesses subject's completion of movement using following criteria:

  • Hand and leg must clear floor by about 6 inches (15 cm) in extended postion.
  • No contact is made with floor with moving arm and let while performing repetitions

Indicate if subject is able to complete movement using criteria within three attempts on both sides. Record scores for both sides indicating if subject was able to complete unilateral repetition, and if not, if they were able to complete diagonal repetion. Also note any performance issues and if pain or discomfort was experienced. 


Dynamic Stability

  • Trunk stability
    • During asymmetric upper and lower extremity motions
    • Sagittal and Transverse planes


Score Criteria
3 Unilateral
2 Diagonal
1 Fail Diagonal
0 Pain

If pain is felt during this movement or Spinal Flexion Clearing Test, score 0 and refer out for orthopedic evaluation.


This test is part of the Functional Movement Screening (FMS). Score of 2 or less, discontinue activities until corrected:

  • Conventional core training
  • Training that would cause high threshold core control
