Delivering script therapy for people with aphasia in EVA park: Two single case treatment studies

BACKGROUND: There are few applications of virtual reality (VR) in aphasia rehabilitation. EVA Park is an online VR platform developed with and for people with aphasia. Our research is testing its potential to host aphasia therapies. OBJECTIVE: Two case studies evaluated if delivery of Script Therapy in EVA Park is feasible and acceptable to participants, whether it improved production of trained scripts and promoted generalisation to untrained scripts, narrative speech and functional communication. METHODS: Two participants with aphasia received 20 hours of Script Therapy in EVA Park. Feasibility was assessed through session attendance, completion of practice and ratings of treatment fidelity. Acceptability was explored via post therapy interviews. The impact of therapy on script production, narrative production and functional communication was assessed through measures administered twice before therapy, immediately post therapy and at 5 weeks follow up. RESULTS: Participants attended at least 85% of sessions. Compliance with practice was good for one, but not the other. Fidelity ratings indicated that over 80% of core treatment components were fully present in recorded sessions. Participants expressed positive views about the intervention. Therapy significantly improved the production of words in trained scripts, with maintenance for one participant. Neither participant improved in the production of untrained scripts or personal narratives. One improved on the assessment of functional communication, but the margin of change was small. CONCLUSIONS: The study adds to the evidence that EVA Park can host a range of interventions and that this platform is acceptable to its intended user group.
