简要总结
The aim of this study is to investigate the effects of high-frequency short duration tablet-based speech and language therapy (teleSLT) mixed with cognitive training (teleCT) in chronic stroke patients. Recent studies suggest that chronic stroke patients benefit from SLT with high frequency and that cognitive abilities can play a role in sentence comprehension and production by individuals with aphasia. To investigate the effects of the distribution of training time for teleSLT and teleCT the investigators use two combinations. In the experimental group 80% of the training time will be devoted to teleSLT and 20% to teleCT whereas in the control group 20% of the training time will be devoted to teleSLT and 80% to teleCT. Both groups receive the same total amount and frequency of intervention but with different distributions. At three time points (pre-, post-test and 8 week follow-up) the patients' word finding ability is measured.
详细描述
A recent Cochrane intervention review revealed evidence for the effectiveness of using speech and language therapy (SLT) for people with aphasia following stroke in terms of functional communication, receptive and expressive language. The authors highlight positive effects of higher training frequency on functional outcome. Also other authors emphasizes the importance of training frequency. In the meta-analysis with 968 patients the authors found that only intervention studies with more than five hours training per week lead to positive effects on speech and language function. They highlighted that it might be better to train short but with a high frequency than long with a low frequency. While some researchers emphasizes the benefit of early intervention, several studies found that also chronic stroke patients can benefit from intensive SLT. One possible approach to increase training frequency and duration is to complement therapist delivered usual care SLT (ucSLT) with telerehabilitation SLT (teleSLT) delivered in the patient's home.
Aphasia is frequently accompanied by deficits of working memory (WM), speed of processing (SP) and executive functions (EF). Recent studies suggest that these cognitive abilities can play a role in sentence comprehension and production by individuals with aphasia and that WM, SP and EF can be enhanced with intensive practice. The authors suggest that SLT therapy should be accompanied with cognitive training (CT). It remains however unclear what percentage of the training time should be devoted to SLT and to cognitive training respectively. For the current study the investigators will use two combinations of teleSLT and telerehabilitation cognitive training (teleCT), where one combination will have a higher percentage of time devoted to teleSLT and the other a higher percentage devoted to teleCT. The latter will serve as the control group to examine the effect of teleSLT.

结局指标
主要结局
Understandability of verbal communication
时间窗: 8 week follow-up (Change from Baseline at week 12)
The understandability of verbal communication is assessed with the A-scale of the Amsterdam-Nijmegen Everyday Language Test (ANELT). For this scale, oral answers in ten everyday life scenarios are scored with respect to understandability of the message, i.e. the content of the message independent of the linguistic form of the utterance (Blomert, Kean, Koster, \& Schokker, 1994). The measurement is performed in a face-to-face interaction between the patients and the evaluator and takes place eight weeks after the intervention.

- Intelligibility of verbal communication(8 week follow-up (Change from Baseline at week 12))
- Perceived quality of life(8 week follow-up (Change from Baseline at week 12))
