  1. Testing was performed with the tensioning device held in three locking states (unlocked, locked-clockwise and locked-counterclockwise. Individual strand response to loading (top-medial, top-lateral, bottom medial and bottom lateral) are recorded at each position (01, 02, 03: neutral; D30, P30: distal or proximal excursion; M30, L30: lateral or medial excursion).
