We all are aware that speech treatment in
developmental motor speech disorders is an under-researched area. We also know how
important it is to find out whether current treatments help children to communicate
more successfully. However, one of the main challenges we are facing is the
lack of detailed information on how the few treatment studies that were
conducted were designed and carried out. This lack does not just affect
research by making it more difficult to repeat treatments to confirm its
success for other speakers. It also means that speech and language therapists,
who want to apply the approaches described in the literature, have very little
information that could assist them in understanding what made those approaches
successful.
This issue was the starting point for Erika Levy’s
most recent article published in the International
Journal of Speech-Language Pathology. Unlike most articles, which usually focus
on outcome and improvements in speech, it details how speech treatments were
carried out in the Speech Production and Perception Lab at Teachers College,
Columbia University. In her article, Levy focuses on two approaches that were successfully
used in the past to improve speech function in children with CP and dysarthria:
-Speech Systems Approach
-Lee Silverman Voice Treatment
Both approaches featured in previous blog entries. The
former aims at improving the functioning, coordination and control of
breathing, phonation and articulation, whereas the latter focuses on producing loud
and clear speech. For both approaches Levy describes treatment protocols which
include specific information on preparation and progression of treatment
sessions, session structure, the tasks that were used, and how children can be
motivated to do these tasks repeatedly.
The article also describes how best to record
speech, and how these speech samples could be used for acoustic analyses. It further
refers to a range of games and apps that could be used to keep children engaged
in the therapy process as well as provide feedback on their performance.
By providing treatment specifics and strategies Levy
intends to reduce some barriers that exist when it comes to researching speech
treatment in developmental dysarthria. I do hope that this article will
trigger further clinical research with the ultimate aim of designing treatments
that will help children to be successful communicators.
