ECoLoGiC Speech Therapy for Everyday Communication in Aphasia

ECoLoGiC Speech Therapy Treatment: Meeting the Everyday Communication Needs of People With Aphasia Following Stroke

The primary goal of this clinical trial study is to evaluate the effect of a new therapy to improve talking in people with the language disability 'aphasia' after a stroke. The therapy is called: 'Expanding Communication and Language Generated in Conversation Treatment' (ECoLoGiC Treatment), and helps improve language skills for talking to other people in conversation. The second goal is to develop training materials to teach families of people with aphasia about the therapy and how to practice at home. This part of the study will be completed with help from two people with aphasia and a family member who have completed the program.

The study asks:

1. How do people with aphasia improve their language skills following this therapy? Results will be determined by using tests of language and by testing language in conversation and other types of talking tasks, like describing a picture.
2. After completing the family training, do family members use the ideas they learned when talking to the person with aphasia? And, what do family members and people with aphasia think of the family training? The first question will be answered with a checklist to see if the family members followed the ideas they learned. The second question will be answered by talking with the people with aphasia and the family members to find out what they thought.

The people with aphasia will complete language testing before and after therapy, and 6 weeks later (to see if improvements are maintained). Therapy is twice a week for one hour, for 10 weeks with a speech-language pathologist. During therapy, the person will have casual conversations with the speech-language pathologist, who will help the person communicate by giving small amounts of help at a time. The speech-language pathologist will tell the person what they are doing that does and does not help with communication. This process helps the person use more language and learn how to communicate better. The family members will have training with the speech-language pathologists to learn about the therapy and how to continue with the ideas at home. Training will take place over 3 sessions, scheduled in addition to therapy sessions. After therapy ends, the family members will have conversations with the person with aphasia, to show what they have learned. Each family member and person with aphasia will also have a 10-20 minute conversation with a researcher to share their thoughts about the training program.

Study Overview

• Status: Completed
• Conditions: Aphasia
• Intervention / Treatment: Behavioral: Expanding Communication and Language Generated in Conversation Treatment

Detailed Description

This study will be conducted with 7 people who have moderate to severe aphasia. Each person will receive ECoLoGiC Treatment. Since each person will receive the same therapy, they do not need to be assigned to different therapy groups. The impact of the therapy will be determined by comparing each person's language skills from before therapy to just after therapy; and from before therapy to 6 weeks following therapy. Language skills will be tested at these three different times (before therapy; after therapy; and 6-week follow-up) by the principal researcher. The 6-week follow-up testing is done to see if the person is still experiencing the improvements that happened just after finishing therapy. Family members of two of the participants will complete the Family Training Protocol to learn more about how to facilitate and support communication at home using principles of ECoLoGiC Treatment.

Each of the three "Testing Phases" will be two weeks long. Each person with aphasia will come for testing sessions three times during the two weeks. If the person wants to divide the testing over more than three visits during two weeks, they can. Tests will include language exams, patient and family self-rating scales and samples of language (i.e., everyday social conversations; and monologues, such as describing a picture). The 15-minute conversation samples will be with the principal researcher, who is a licensed speech-language pathologist and with a self-selected family member. Language sampling techniques for both monologues and conversation will follow standard procedures.

Each person will receive therapy twice a week for 10 weeks. Sessions will be for 60 minutes with a licensed speech-language pathologist who is a lab member and who has been trained in ECoLoGiC Treatment, and who has at least 1 year of experience working with people with aphasia. For individuals completing the Family Training Protocol, three training sessions will be scheduled with the delivering therapist (usually either just before or just after a regularly scheduled therapy session).

Results of the study will be analyzed for each individual with aphasia to determine the amount of change from before therapy to after therapy, and also from before therapy to the follow-up visit (6 weeks later). Test results and patient and family self-report scales will be analyzed according to the test manuals, related journal articles, or whether change is greater than a 10 percent benchmark.

The conversation and monologue samples will be evaluated for language skills, such as vocabulary and grammar, using established language measures. The results will then be analyzed statistically, to determine changes for each person and for the group (using a linear mixed model). Additional calculations will be completed for each person for each of the language measures to determine the amount of change (i.e., effect size), and to determine if the amount of change is greater than the minimal detectable change.

The Family Training Protocol will be analyzed quantitatively for a) Family member fidelity to the protocol during three conversations held at post-treatment and at the 6-week maintenance phase; and b) qualitatively through semi-structured interviews between the Principal Investigator and the person with aphasia; and the Principal Investigator and the trained Family Member, conducted post-treatment.

Intervention / Treatment

Experimental: Expanding Communication and Language Generated in Conversation Treatment; Participants will complete 20 one-hour therapy sessions over 10 weeks with an experienced, trained, and licensed speech-language pathologist delivering Expanding Communication and Language Generated in Conversation Therapy, following the therapy protocol. Sessions will take place through casual conversational interactions, with incremental problem-solving and communication support by the speech-language pathologist.

Behavioral: Expanding Communication and Language Generated in Conversation Treatment; ECoLoGiC Treatment is a behavioral therapy developed to improve language abilities in everyday conversation for people with aphasia. It is delivered through therapeutic use of spontaneous conversational interactions between a speech-language pathologist and a person with aphasia. ECoLoGiC Treatment is based on theories of conversational interaction in adults without communication disorders, as well as on theories of neuroplasticity, rehabilitation, and learning. The therapy consists of two components: a) Therapeutic Conversation, during which the pair discuss any topic of interest to the person with aphasia, while the speech-language pathologist uses techniques to promote social interaction; and b) Therapeutic Repair, used when communication breakdown occurs. At this time, the speech-language pathologist implements the intervention's 7-step least-to-most hierarchy, supporting the person's independence and learning in communicative problem-solving to communicate the desired idea.
