    Laurie J. Slovarp, PhD, CCC-SLP is an Associate Professor in the School of Speech, Language, Hearing, and Occupational Sciences at University of Montana. Dr. Slovarp received a Master’s of Science degree in Speech and Hearing Sciences from Arizona State University in 2000 and a PhD in Independent Interdisciplinary studies at University of Montana in August 2015.  Following attainment of her M.S. degree, she worked in hospital, outpatient rehabilitation, home health, skilled nursing and university settings for 10 years. She joined the CSD faculty at University of Montana in 2010.

    Dr. Slovarp is a swallowing, voice, and upper airway specialist with specialty training in fiberoptic endoscopic evaluation of swallowing (FEES) and videostroboscopy. She is the director of the Voice Outcomes and Inquiry of Cough and Essentials in Swallowing (VOICES) lab. She has published several peer-reviewed research papers and presented at multiple state and national conferences. Her current research is focused on improving care for patients with chronic cough due to cough hypersensitivity syndrome (CHS). Her research agenda focuses on the following long-term objectives:

    1. Improve efficacy, efficiency, and cost-effectiveness of care of patients with chronic cough due CHS.
    2. Develop new and innovative assessment and treatment strategies that target gaps and inadequacies in current management techniques and models for patients with CHS.
    3. Understand the underlying mechanisms involved in cough hypersensitivity and behavioural cough treatment.

    Dr. Slovarp’s research has been supported through the Mountain West Clinical Translational Research Infrastructure Network (MW-CTRIN) and the Montana IDeA Network of Biomedical Research Excellence (INBRE) under grants from the National Institute of General Medical Sciences. She has also been awarded funding through the University of Montana Small Grant Program and the American Speech Language Hearing Association.

Current Ongoing Research

  • Development of a screening tool to identify patients with chronic cough who are candidates for behavioral cough therapy (BCT)
    • ​This study is currently in the second phase.  A 52-item bank of potential screening questions was developed by an expert panel.  An initial sample of 132 participants was collected on the initial screening questions before beginning BCT. The participants were classified as BCT-success and BCT-non success according to their response to BCT. A statistical model was constructed using a Gradient Boosting Machine (GBM) to predict which questions best predicted whether participants improved or not with BCT. The 15 items with the largest influence in the model were retained. We are currently collecting data on the 15-item questionnaire.  
  • Progressive desensitization paried with behavioral cough therapy for the treatment of refractory chronic cough
    • This study will employ a blinded, randomized complete block, placebo-control trial design. European Respiratory Society (ERS) Guidelines will be followed when taking the following baseline and post-treatment measures: (1) cough sensitivity testing, (2) 24-hour cough count using the Leicester Cough Monitoring technique, and (3) the Leicester Cough Questionnaire (LCQ), a validated quality of life measure. We will enroll 25 patients with RCC who have not sufficiently responded to behavioral cough therapy (BCT) alone. Patients will be randomly assigned to treatment or placebo group with one block defined by type of cough trigger (mechanical vs non-mechanical). The treatment phase will consist of six sessions, across three weeks, whereby patients will be exposed to repeated trials of either saline vapor (placebo) or capsaicin vapor (treatment). Following each exposure, participants will employ cough suppression techniques. Capsaicin dose in the treatment participants will be increased incrementally during each session, as tolerated. Post-treatment measures will be taken at one week and three-weeks post treatment. Assessors and participants will be blinded.
  • Investigating the underlying mechanism responsible for the effect of behavioral cough therapy
    • This project is in collaboration with Sarjubhai Patel, PhD who is a neuroscientist. Brush biopsies will be obtained from the nose and epiglottis (under physician supervision) of participants pre and post BCT. The biopsies will be analyzed using qPCR for TRPV mRNA expression and by Western blot analysis to measure TRPV expression. Comparisons of TRPV expression between pre and post-BCT will be quantified to assertain if BCT produces significant changes in TRPV expression at the course of intervention.
  • Establishing validity of using sEMG to measure cough frequency
    • sEMG data will be collected from four different respiratory muscles over the course of several hours and compared to objective cough frequency data to measure sensitivity and specificity.
