Welcome to the ANCDS Aphasia Treatment Website!
This website includes composite tables of aphasia treatment studies
reported in the literature.
The studies have been grouped according to the nature of the
primary outcome variable (e.g., lexical retrieval). In other words, the
studies are grouped by the dependent variable of interest in the study.
The tables include information regarding the study design, class
and phase of treatment research, and the type of treatment. Note that
this website is being updated frequently, so that ultimately all cells
in the tables will be filled in.
Study Designs are coded as follows:
||Between group design
||Within group design
||Single subject design
||Case study (non experimental)
Class of Study coded in accordance with American Academy of
Neurology guidelines (2001)
||Evidence provided by:
One or more well designed randomized control
trials, including meta-analyses of such trials
||Well designed observational studies with concurrent
controls. Single subject multiple baseline studies across subjects.
||Expert opinion, case studies, case reports, studies
with historical controls. Single subject multiple baseline studies
Phase of treatment research is coded according to Robey and
to determine if there is evidence to suggest
that a tx has therapeutic value
|| to develop, standardize, validate, and optimize
to explain why treatment works; who are ideal
||tests tx efficacy under ideal conditions
||to determine effectiveness of treatment under
ordinary conditions of use
