Each larynx was subjected to physiological conditions with with constant (static) or cycling (dynamic) flow. The specimens were tested sequentially in each of 4 conditions: 1) bilateral full abduction\n                    <jats:italic>(Control<\/jats:italic>\n                    1); 2) transection of the suture on the side without PMMA; 3) bilateral abduction achieved by replacing the suture\n                    <jats:italic>(Control<\/jats:italic>\n                    2); and 4) cutting the suture on the PMMA side. Tracheal pressure and flow and pressure in the flow chamber were recorded using pressure and flow transducers. The strain experienced by each suture during bilateral abduction\n                    <jats:italic>(Controls 1<\/jats:italic>\n                    and 2) was measured.
