Internal Investigations

This investigation aims to leverage advances in machine vision to develop algorithms that can take in standard videofluoroscopy recordings of swallows and output reliable MBSImP scores. To accomplish this a multi-stage machine vision algorithm has been developed to build machine learning guided by expert knowledge from speech language pathologists. PhD Candidate Principal Investigator: Alex [...]

The aim of this investigation is to examine the relative severity of Stroke, PD, COPD, and Dementia Patients for each of the 17 MBSImP components. To accomplish this we leverage the large amount of data in the MBSImP Swallowing Data Registry, a centralized deidentified clinical database, to calculate the relative severity of each diagnosis for [...]

The goal of this study is to investigate the diagnostic validity of clinical markers used during clinical swallow evaluations (CSE). Knowing how sensitive and specific our clinical markers are in detecting physiologic swallowing impairment and airway invasion events is an essential step to improve the validity of CSEs, inform targeted treatment planning, reduce unwarranted testing and [...]

The aim of this study is to determine temporal measures underlying improved swallowing function when initiated during expiration at low to mid-lung volume during quiet breathing. Principal Investigator: Dr. Brittany Krekeler Co-Investigators: Dr. Bonnie Martin-Harris Dr. Cagla Kantarcigil Kate Davidson Kent Armeson

The aim of this investigation is to quantify the impact of spatial resolution on clinical judgments of swallowing impairment in adults. Principal Investigator: Kate Davidson Co-Investigators: Dr. Bonnie Martin-Harris Abigail Nellis Kent Armeson

The goal of this study is to investigate the impact of high flow nasal cannula on respiratory-swallowing physiology in patients with moderate to severe COPD. Principal Student Investigator: Raneh Saadi Research Mentors: Dr. Bonnie Martin-Harris Dr. Hameeda Shaikh Dr. Julia Lee

The goal of this study is to explore the relationship between lung volumes, respiratory phase at swallow initiation, and swallow physiology in lung transplant patients pre- and post-operatively. Student Principal Investigator: Kahla Graham Research Mentors: Dr. Bonnie Martin-Harris Dr. Rade Tomic Dr. Ambalavanan Arunachalam Dr. Elizabeth Norton Dr. Julia Lee [...]

The goal of this study is to assess respiratory-swallow coordination and the impact of bolus characteristics in individuals with Parkinson's Disease. Student Principal Investigator: Rabab Rangwala Research Mentors: Dr. Bonnie Martin-Harris Dr. Cagla Kantarcigil

The goal of this study is to provide values for the normal range of proximal esophageal musculature as well as temporal variables not currently factored into high-resolution esophageal manometry. Principal Investigator Dr. Erin Reedy Co-Investigators Dr. Bonnie Martin-Harris Dr. John Pandolfino
