PURPOSE: Aphasia group therapy offers many benefits, however people with aphasia report difficulty accessing groups and speech-language pathologists are faced with many challenges in providing aphasia group therapy. Telerehabilitation may offer an alternative service delivery option. An online aphasia group therapy program - Telerehabilitation Group Aphasia Intervention and Networking (TeleGAIN) - has been developed according to the guidelines of the Medical Research Council (MRC) framework for complex interventions. The purpose of this paper is to describe the development of TeleGAIN and the results of a pilot trial to determine feasibility and acceptability. METHOD: The development of TeleGAIN was informed through literature reviews in relevant topic areas, consideration of expert opinion and application of the social cognitive theory. TeleGAIN was then modelled through a feasibility pilot trial with four people with aphasia. RESULT: TeleGAIN appeared to be feasible and acceptable to participants and able to be implemented as planned. Participant satisfaction with treatment was high and results suggested some potential for improvements in language functioning and communication-related quality of life. CONCLUSION: TeleGAIN appeared to be feasible and acceptable, however the study highlighted issues related to technology, clinical implementation and participant-specific factors that should be addressed prior to a larger trial.
