Primary
| Measure | Time frame |
|---|---|
| Word recognition score. Timepoint: pre-intervention, immediately post-intervention, one month after completion of intervention. Method of measurement: the percent of words correctly repeated by using Two lists of 35 phonetically balanced monosyllabic words.;Sentence recognition score. Timepoint: pre-intervention, immediately post-intervention, one month after completion of intervention. Method of measurement: the percent of key words correctly repeated by using 8 list pairs of 10 sentences. | — |
