Detailed Description
Every year thousands of persons in Sweden suffer from brain damage resulting in anomia, that is, word finding difficulties affecting their ability to talk to other people. Anomia is one of the most common and persistent symptoms of aphasia following a left hemisphere stroke, but it is also common in in progressive neurological diseases such as Parkinson's disease or multiple sclerosis (MS). There is evidence that more intensive speech language therapy may improve speech even in a chronic (> six month post stroke) phase of aphasia. However, access to the necessary amount of speech language therapy is limited due to lack of financial resources as well as to limitations to service providers in more rural areas.
It has been suggested that telepractice may increase the access to speech-language therapy for more people but there is a lack of knowledge of whether there is a difference in outcome from interventions provided as In-Clinic therapy (I-CT) or as telepractice therapy (TP-T).
Verb Network Strengthening Treatment (VNeST) is an anomia therapy focused on the production of short phrases. The participants generate thematically related verbs and nouns to strengthen the neural connections between the action (verb) and related thematic roles (agents and patients). From orally and written stimuli, the participants are asked to tell whom (subject) may do something (verb) with what (object) and then to do short expansions from this basic phrase. So far, results from single-case experimental design studies performed by Edmonds and colleagues are promising, showing generalization of outcomes to untrained items. Moreover, improvement in word finding was observed in other tasks like object and verb naming as well as sentence production and partly to connected speech.
The present project explores the effectiveness of VNeST, first in a small pilot study, then in a clinical trial including 80 participants. Participants with left hemisphere aphasia will be randomized to either an in-clinic therapy (I-CT) group or a telepractice therapy (TP-T) group and provided VNeST following the same treatment protocol based on Edmonds (2014).
Outcome measure include measures of naming ability on word- and phrase levels as well as in discourse. Measures of participant reported perceptions of functional communication and communicative participation as well as health related quality of life (PROMs) are also included.

Intervention / Treatment |
---|---|
Experimental: Telepractice treatment (TP-T)
Participants will receive 30 hours of training, 2-3 times a week in ten weeks using Verb Network Strengthening Treatment (VNeST). Treatment will be done with a speech-language pathologist providing the therapy through an online platform. |
Participants are presented with a verb (representing an activity, for example, driving) orally and in writing.
The participants are first asked to name someone who may perform the given activity (an agent, for example, a chauffeur), then to name an object which the given activity may be performed with (a patient, for example, a limousine).
Several types of semantic clues and assistance are provided if the participant is having difficulties finding adequate nouns.
This procedure is repeated for three different agents and objects related to the given verb.
The participants are then asked to choose one of the three phrases participants have created and expand on it by telling where, when and why the agent is performing the activity.
After this the participant are given sentences (with several foils) including the activity as well as agents and patients, and are asked to indicate whether the sentences are correct or not.

Active Comparator: In-clinic treatment (IC-T)
Participants will receive 30 hours of training, 2-3 times a week in ten weeks using Verb Network Strengthening Treatment (VNeST). Treatment will be done with a speech-language pathologist providing the therapy in person at a clinic. |
