Objective:
Clinical treatment strategies and progress metrics for patients with inducible laryngeal obstruction (ILO) and exercise-induced laryngeal obstruction (EILO) have not been systematically applied across clinics. The goals of this review were to identify the intervention strategies used to treat upper airway disorders and determine the clinical metrics by which improvement or resolution of ILO/EILO is determined in clinical studies of speech-language pathology intervention.
Method:
A systematic review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Systematic Reviews Checklist. English language, full-text publications were identified through MEDLINE (Ovid), APA PsycINFO, and Web of Science for publications that described clinical outcomes following behavioral treatment for ILO provided by a speech-language pathologist (SLP).
Results:
A total of 238 sources were retrieved, of which 75 were duplicates. Titles and abstracts of 163 were screened, with 22 sources included for full-text review. Citation review yielded nine additional resources. Thirty-one sources were included for data extraction. Most sources described use of respiratory/laryngeal retraining. There was a lack of consistency for clinical and standardized metrics used to evaluate improvement or resolution of upper airway symptoms.
Conclusions:
Behavioral and standardized outcome metrics for evaluating therapy outcomes from SLP behavioral intervention of ILO/EILO are not consistently applied. Clinical metrics standards for clinicians are needed to provide a means to evaluate graded improvement in treatment and changes in health care utilization as well as for training less-experienced clinicians.
