This pattern begins with hip extension which initiates the roll and leads to pelvic rotation/lumbar extension and culminates in trunk extension/rotation, completing the roll.
This pattern helps to identify altered motor sequencing, timing and force expression of gluteal muscles by isolating hip extension/lateral rotation. Patient lies prone with legs extended and slightly abducted; arms flexed overhead, also slightly abducted. Head is in neutral rotation. When rolling toward the left side of the body the axis of rotation is formed by the lower extremity of the side that the individual is rolling toward and the upper extremity of the side the individual is rolling from, or in this case the left lower extremity and right upper extremity, respectively.
Attempt to perform with a fully extended lower extremity, but if unable to complete the roll, the client may flex the knee if needed in order to initiate the roll. Cue to extend at the hip and then at the knee.
