A movement review is an excellent touch point to see exactly what DARI can collect and to better understand its importance in your motion health!
The reverse lunge with rotation is a great movement to capture truck separation between the thoracic and lumbar segments. It does this by putting the subject in a split stance so that the hips and lower body cannot aid in the trunk rotation. Isolating the trunk during a rotational movement is important to understand a subject's true capability as truck rotation is very important in carrying out everything from activities of daily living to baseball pitching.
When reporting the results of this movement we not only look at the primary plane rotation, but also any secondary plan movement such as flexion that occurred for the subject to achieve their maximum rotation.
