Deep learning-based video analysis for automatically detecting penetration and aspiration in videofluoroscopic swallowing study

Soyoung Kwak, Jeoung Kun Kim, Jun Sung Moon, Gun Woo Lee et autres

The videofluoroscopic swallowing study (VFSS) is the gold standard for diagnosing dysphagia, but its interpretation is time-consuming and requires expertise. This study developed a deep learning model for automatically detecting penetration and aspiration in VFSS and assessed its diagnostic accuracy. Images corresponding …

Prediction of Ambulatory Functions Based on Somatosensory and Motor-Evoked Potentials in Patients with Intracerebral Hemorrhage and Intraventricular Hemorrhage Extension

Min Cheol Chang, Seong Yeob Kwak, Soyoung Kwak

OBJECTIVE: This study investigated the usefulness of somatosensory-evoked potentials (SEPs) and motor-evoked potentials (MEPs) in predicting motor outcomes in patients with intracerebral hemorrhage (ICH) and intraventricular hemorrhage (IVH) extension. METHODS: We retrospectively evaluated 124 patients with ICH and IVH extensions. SEPs of …

Usefulness of barium sulfate and iohexol as contrast agents for VFSS in visualizing components of swallowing predictable of poor outcomes

Min Soo Kang, Min Cheol Chang, Soyoung Kwak

Barium sulfate and iohexol are commonly used as contrast agents for videofluoroscopic swallowing study (VFSS). This study compared their usefulness as contrast agents in visualizing components of swallowing predictable of subsequent pneumonia and unintentional weight loss after VFSS. This was a randomized, …

Inspiratory Muscle Training

Soyoung Kwak

Inspiratory muscle training (IMT) is a technique that aims to improve the function of the inspiratory muscles. Because inspiratory muscle dysfunction is closely related to dyspnea, which is the most salient exercise-limiting symptom of patients with chronic lung diseases, IMT has been …

Prognosis prediction for impaired consciousness recovery in stroke patients using videofluoroscopic swallowing study: A retrospective observational study

Sung Ho Jang, Soyoung Kwak, Min Young Lee

Prognosis prediction of impaired consciousness is clinically important for establishing therapeutic strategies, determining a rehabilitative goal and functional outcome, and estimating rehabilitative therapy duration. In this study, we investigated the prognosis prediction value of videofluoroscopic swallowing study (VFSS) in recovery of impaired …

Effectiveness of Extracorporeal Shockwave Therapy on Controlling Spasticity in Cerebral Palsy Patients: A Meta-Analysis of Timing of Outcome Measurement

Min Cheol Chang, Yoo Jin Choo, Sang Gyu Kwak, Kiyeun Nam et autres

Extracorporeal shockwave therapy (ESWT) has been suggested as an alternative treatment for reducing spasticity in patients with cerebral palsy (CP). However, the duration of its effect was rarely known. A meta-analysis was performed to investigate the effectiveness of ESWT at controlling spasticity …
