TORSO ROCK
Summary
Torso Rock measures the average angular
rotational range of the chest to the left and right.
DETAILS
In more detail, Torso Rock represents the average
angular rotational range of the torso, measured
at the sternum once per second along the local
sagittal axis (the sagittal axis intersects the lower
back and the abdomen area above the pelvis).
A larger Torso Rock value indicates higher average
torso rotation and a lower value indicates more
limited rotation. Although torso movement from
side to side can generally be called “rocking,” it
is important to note that the amount of rocking
observed is dependent on both torso rock and
pelvic rock.
SCORE
Each clockwise and counterclockwise rotation
occurring within a second is recorded and
averaged, resulting in an angular score.
