Key inclusion criteria
All consecutive stroke patients admitted to Stroke rehabilitation ward at The Princess margaret Hospital, Christchurch NZ are currently screened for communication disorder. From October 3 2005 every second patient will be requested to participate. The screening tool includes a benign question to introduce the topic of telephone communication. Patients (or their families) who provide positive responses to these telephone questions, or who report at any time in therapy, that communication over the phone is superior, will also be referred to the research project.

Brief summary
Aphasia is a communication disorder that occurs following a stroke. Some families or friends of aphasic stroke patients at TPMH have spontaneously reported that their relatives communication during telephone conversations (TC) appears superior to their face to face conversations (FFC). This study seeks to determine whether this impression can be confirmed by comparing the patients communicative ability in these two settings. The study is also interested in establishing; (1) whether the familiarity (of the aphasic speaker) with their conversation partner influences the individuals communication in these settings and, (2) whether different types of aphasia alter the individuals communicative ability in these settings.There will be a minimum of one and a maximum of 10 participants. The method will be a series of single subject designs.
Each patient will represent a single case study, which can stand alone, but when sufficient cases are collected, group results will be analysed.
This is a single subject, quasi experimental ABAB paired design with each patient acting as his or her own control. The following will be analysed and compared for each patient - language impairment, communication functioning, relationship of conversation partner to participant. For each conversation, the conversation partner will be requested to indicate the level of difficulty \ ease (using a visual analogue scale) that they experienced whilst communicating with the patient. Each conversation will be for maximum of 10 minutes, but due to severity of the aphasia, it is anticipated that many conversation sets may be shorter than this.
Each study may stand alone but if/when sufficient cases are collected, group results may be analysed. The total time period for any one patient to complete all conversations is within 14 days.
