Brief summary
The purpose of this study is to examine the efficacy of the Ubiquitous Spaced Retrieval-based Memory Advancement and Rehabilitation Training (U-SMART) in the elderly individuals with mild cognitive impairment (MCI) by an open-label, controlled, crossover Trial.
Detailed description
The Spaced Retrieval-based Memory Advancement and Rehabilitation Training (SMART) which consisted of 24 one-hour face-to-face sessions (Lee, Park et al. 2009) was developed based on the spaced retrieval training (SRT), which was effective in improving memory retention span of very mild to mild Alzheimer's disease patients. The Ubiquitous SMART (U-SMART) by transforming the current SMART to a self-administered program using an application working on IPAD was developed, and showed its feasibility and efficacy in the elderly individuals with mild cognitive impairment in the preliminary study. (ClinicalTrials.gov ID: NCT01628653) To validate the efficacy of the U-SMART, an open-label, controlled, crossover design of clinical trial were planned in this study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in the Word List Test (memory, recall, recognition) of the CERAD Neuropsychological Assessment Battery before and after phase I intervention and before and after phase II intervention (crossover part of the study) | Baseline, 5 weeks, 11weeks | To evaluate the efficacy of the U-SMART, the Word List Memory Test (WLMT), Word List Recall Test (WLRT), Word List Recognition Test (WLRcT) of the CERAD neuropsychological assessment battery were applied to all participants. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in the Subjective Memory Complaints Questionnaire (SMCQ) before and after phase I intervention and before and after phase II intervention (crossover part of the study) | Baseline, 5 weeks, 11weeks | To evaluate the subjective memory improvement after the U-SMART, the Subjective Memory Complaints Questionnaire(SMCQ) was applied to all participants. |
| Change in the Geriatric Depression Scale (GDS) before and after phase I intervention and before and after phase II intervention (crossover part of the study) | Baseline, 5 weeks, 11weeks | To evaluate the subjective mood after the U-SMART, the Geriatric Depression Scale was applied to all participants. |
| Change in the Mini-Mental State Examination before and after phase I intervention and before and after phase II intervention (crossover part of the study) | Baseline, 5 weeks, 11weeks | To evaluate the global cognitive function after the U-SMART, the Mini-Mental State Examination was applied to all participants. |
