To test the feasibility of a randomised controlled trial comparing face to face and remotely delivered word finding therapy for people with aphasia.
A quasi-randomised controlled feasibility study comparing remote therapy delivered from a University lab, remote therapy delivered from a clinical site, face to face therapy and an attention control condition.
A University lab and NHS outpatient service.
Twenty-one people with aphasia following left hemisphere stroke.
Eight sessions of word finding therapy, delivered either face to face or remotely, were compared to an attention control condition comprising eight sessions of remotely delivered supported conversation. The remote conditions used mainstream video conferencing technology.
Feasibility was assessed by recruitment and attrition rates, participant observations and interviews, and treatment fidelity checking. Effects of therapy on word retrieval were assessed by tests of picture naming and naming in conversation.
Twenty-one participants were recruited over 17 months, with one lost at baseline. Compliance and satisfaction with the intervention was good. Treatment fidelity was high for both remote and face to face delivery (1251/1421 therapist behaviours were compliant with the protocol). Participants who received therapy improved on picture naming significantly more than controls (mean numerical gains: 20.2 (remote from University); 41 (remote from clinical site); 30.8 (face to face); 5.8 (attention control); P <.001). There were no significant differences between groups in the assessment of conversation.
Word finding therapy can be delivered via mainstream internet video conferencing. Therapy improved picture naming, but not naming in conversation.
测试一项随机对照试验的可行性，该试验比较针对失语症患者的面对面和远程单词查找治疗。
一项准随机对照可行性研究，比较从大学实验室提供的远程治疗、从临床地点提供的远程治疗、面对面治疗和注意力控制条件。
一个大学实验室和国民保健服务（NHS）门诊服务机构。
21名左半球中风后失语的患者。
将八节面对面或远程提供的单词查找治疗课程与一个注意力控制条件进行比较，该注意力控制条件包括八节远程提供的支持性对话课程。远程条件使用主流视频会议技术。
通过招募和损耗率、参与者观察和访谈以及治疗保真度检查来评估可行性。通过图片命名测试和对话中的命名来评估治疗对单词检索的影响。
在17个月内招募了21名参与者，1名在基线时失访。对干预的依从性和满意度良好。远程和面对面交付的治疗保真度都很高（1251/1421项治疗师行为符合方案）。接受治疗的参与者在图片命名方面的改善明显超过对照组（平均数值增益：20.2（大学远程）；41（临床地点远程）；30.8（面对面）；5.8（注意力控制）；P<.001）。在对话评估中，各组之间没有显著差异。
单词查找治疗可以通过主流互联网视频会议进行。治疗改善了图片命名，但未改善对话中的命名。
