| Popis: | Background and Purpose Oropharyngeal dysphagia (OD) is a major complaint following stroke, associated with poor clinical outcome and high mortality rates. We aimed at characterizing the kinematics of swallow response associated with unsafe swallowing in chronic poststroke patients with OD. Patients and Methods Consecutive poststroke patients with a positive volume-viscosity swallow test for OD 3 months following stroke were studied by videofluoroscopy (VFS). Demographical and clinical factors and kinematics of swallow response were compared between those poststroke patients with safe swallow (penetration-aspiration scale, PAS≤2) and those with unsafe swallow (PAS≥3). Receiver operating characteristic (ROC) curves were drawn for laryngeal vestibule closure (LVC) time which predicts unsafe swallow. Results We studied 73 poststroke patients (76.7±9.3 years, 53.4% male) by VFS (60.4% with impaired safety, PAS=4.47±1.44, and 95.9% with impaired efficacy of swallow). Poststroke patients with unsafe swallow presented a poorer functional (Rankin 2.2±1.6 vs 1.2±1.0, P |
