Abstract:
Background: In healthy individuals, airway protection during swallowing involves closure of the
larynx at multiple levels, including adduction of vocal folds. Different vocal adduction exercises have
been reported in swallowing rehabilitation, but no knowledge synthesis on them exists, to date.
Aims: This review aims to understand the extent and type of evidence on rehabilitative vocal
adduction exercises and their effect on swallow physiology in adults with typical or disordered
swallowing. It also presents the outcome measures and principles of rehabilitation, reported.
Methods & Procedures: The Joanna Briggs Institute, and PRISMA-ScR guidelines were used to inform
this review. Electronic databases (MEDLINE (PubMed), EMBASE (Ovid), CINAHL (EBSCO) and Web of
Science) and grey literature were searched from inception to March 2022 inclusive. Articles were
assessed by two independent reviewers to meet the following criteria: (1) rehabilitative vocal
adduction exercise, (2) which instrumentally measured impact on swallowing physiology, (3) in
participants aged ≥18 years with typical and/or disordered swallowing. All types of original research
were examined, with no restrictions on language or setting.
Outcome and Results: A total of 12493 records were identified for title and abstract screening. From
89 studies selected for full text review, 10 were included. In total five vocal adduction exercises,
LSVT (n = 4, 40%), EMST (n = 1, 10%), singing (n = 3, 30%), supraglottic swallow maneuver (n = 1,
10%) and supraglottic swallow combined with effortful pitch glide (n = 1, 10%) were identified for
swallowing rehabilitation, predominantly in adults with neurological disorders. Overall positive
effect on swallowing physiology was noted. Heterogenous set of outcome measures and principles
of rehabilitation were reported.
Conclusions: A diverse set of vocal adduction exercises with heterogeneous effects on swallow
physiology were identified. This review offers the best available evidence on the extent and type of
different rehabilitative vocal adduction exercises, with respect to instrumentally measured impact
on swallowing physiology over time, to inform potential directions for future research and practice.
