Oscillating Technique with Isometric Stabilisation (OTIS) & Impulse Technique with Isometric Stabilisation (ITIS)

Purpose
 

• The OTIS is an oscillating technique with isometric stabilisation. The ITIS is an impulse technique with isometric stabilisation. It challenges static stability of the weight bearing lower quarter.

Description
 

• OTIS:
  • Start in standing, on one foot. Turn the stance foot into external rotation up to 40 degrees, whilst maintaining the pelvis forward facing.
  • Take hold of a tubing, attached lateral to the stance foot.
  • Pull the tubing in short oscillations at a frequency of between 60-80Hz whilst maintaining balance.
• ITIS:
  • Start in standing, on one foot. Turn the stance foot into external rotation up to 40 degrees, whilst maintaining the pelvis forward facing.
  • Have a partner toss a medicine ball across the front of the body, from opposite side of the stance leg. Resist the tendency to be rotated by the impulse of the ball.

Variations
 

• Turn the foot into internal rotation and have the tubing attached on the side that the toes are pointing. Perform oscillation. 

Implications
 

• The oscillations and impulse create reflexive co-contractions around the hip, pelvis and trunk.
