Scoping Review Protocol - Active Components TLS (Duboisdindien, Cattini, Tournery, Durieux).pdf

Rationale

In 2017, Da Cruz Morello et al. concluded that lexical semantic therapies are effective in improving the language skills of AD patients.

Studies on lexical-semantic activation models (e.g. Collins & Loftus, 1975) have contributed to the emergence of research into the language treatment of people with anomia, primarily in patients with post-stroke aphasia, although the term lexical-semantic therapy does not really refer to a specific intervention, but rather to a category of interventions based on lexical-semantic activation models.

In their narrative review, Colliaux and al. (in press) point out important variations according to the studies involving in particular: the profile of the targeted patients, the lack of methodological and theoretical information on such components, the unavailability of control data on the techniques of training or remedial approaches proposed.

This issue concerns many fields involved in scientific research (e.g. medicine, psychology, biology) and an increasing number of authors are arguing for greater precision in the description of interventions in order to allow for good fidelitý of the treatment (Hoffman et al., 2014). A scoping review of these components, considering the original semiological contexts from which they were extracted and their theoretical framework, would make possible the characterisation of the most beneficial components for a lexical-semantic therapy.

Conditions being studied and operational definitions

Anomia: impossibility or marked difficulty in recovering known words that the speaker is certain to know.

Intervention components: observable (and, therefore, in principle, measurable) actions, that are selected or delivered by the clinician used in intervention delivery (e.g., activity, procedure, dosage).

Lexical-semantic therapies: An interventional approach dedicated to word retrieval in anomia, hypothesizing a strengthening of the links between conceptual representations and their lexical-articulatory features. This type of treatment is based on theoretical models of semantic network activation. It includes activities that engage participants in extracting, processing, or modulating semantic information in response to stimuli (image, spoken word, written word, semantic features, etc.) or in retrieving information to identify/produce the target word.
