This is one of our favorite assessments. It can be done anywhere you can stand and have a little room to move. Changes are easily detectable by the person performing the assessment.
Find a spot on the floor that you can return to repeatedly and use tape, a floor board, a carpet stain, etc. to make sure you can return to the same spot and orientation for every assessment.
Stand tall with your feet together with shoes or feet touching.
Put your hands out in front of you, index fingers extended away from you, thumbs up and your remaining fingers interlaced.
Your elbows should be locked. It should feel like you are pointing a gun at something in front of you with the space between the tops of your thumbs as the site.
Warm up and Baseline
Without moving your feet (no shifting or lifting) rotate your full body to one side.
The relationship of your head, hands and shoulders should not change as you move – i.e., you should keep sighting over your thumbs and your elbows should not bend.
Move at moderate speed with minimal tension, until you reach the farthest point where you can hold the position for 2 seconds.
Do 2-3 more rotations until you are consistently pointing to the same spot each time.
The spot where you are pointing, perhaps a landmark on the wall or in the distance, is your assessment result.
At this point, we've eliminated any assessment variation due to warm-up.
