- Lifted wrist, elbow, and knee should remain in line with
- Torso should remain in same plane as board
- No contact is made with floor during while performing repetitions
- Indicate if subject is able to complete movement using criteria
within three attempts on both sides. Test administrator should
note if pain or discomfort was experienced.
- 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 results should note
