Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Direct effect of the intervention on speech ability four weeks after the intervention (rTMS & speech training) (T3) compared with baseline (T0, T1) (Primary outcome: word naming ability & usage of recall strategies) - Direct generalization effects of the intervention: comparison of performance with new test material vs. known test material considering word recall, repeating words after trainer and spontaneous speech (Cookie Theft Picture; ANELT) after the intervention (T3) - Long-term effects of the intervention on speech ability & generalization effects eight weeks after the intervention (T4) - Natural progress and fluctuations in performance of the disorder - Adherence and feasibility: - Adherence (satisfaction with treatment, subjective rTMS side-effects, using questionnaire, number of drop-outs) - Feasibility of a bigger randomized clinical study (number of patients per quarterly period, inclusion criteria, number of patients that want to participate | — |
Secondary
| Measure | Time frame |
|---|---|
| - Change in speech ability over four weeks without an intervention (T2: control of progress 2 vs. T0, T1: Baseline), assessed using parts of Aachener Aphasia Test (repeating words after trainer, speech comprehension, word naming, written language) and additional speech tests [naming performance (nouns and verbs) during screening, verbal fluency (lexical and semantic-categorical), spontaneous speech] - Individual performance progress of speech ability during training (words named correctly during training, written word naming) - Direct effects of intervention on cognition: T3 vs. T0, T1 assessed using Trail making Test (TMT) and Digit-Span-Test - Long-term effects of intervention on cognition: T4 vs. T0, T1 assessed using Trail Making Test (TMT) and Digit-Span-Test - Change of daily functioning (CBI filled in by relatives) - External assessment of communication ability through relatives (CETI and self-created questionnaire KLIA) - Life quality (QHOQOL) - Tolerability and safety of training and stimulation (side effects rTMS, AES, SAEs) - Change of brain activity (T2 vs. T3) at stimulation site and posterior language areas | — |
