Abstract

Objective
We developed the Indoor Cognitive Training combined with Physical Activity (ICT-PA) program, incorporating memory registration, navigation, and image recall through wearable sensors and Bluetooth Low Energy tags, aimed at enhancing cognitive function and physical activity in elderly individuals with mild cognitive impairment (MCI).
Methods
Thirty-six elderly individuals over 60 years diagnosed with MCI participated in a 6-week ICT-PA program. The primary outcome measure was the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery Total Score 1 (CERAD-TS1), and the secondary outcome measures were the Mini-Mental State Examination (MMSE), Subjective Memory Complaints Questionnaire (SMCQ), and Korean version of the Geriatric Depression Scale (GDS-KR). Changes in scores before and after the program were analyzed using paired t-tests. Program satisfaction was evaluated using a 5-point Likert scale.
Results
CERAD-TS1 scores significantly improved after ICT-PA training (pre 57.3±11.3; post 60.3±13.1; p=0.006), while MMSE, SMCQ and GDS-KR scores remained unchanged. Subgroup analysis showed significant CERAD-TS improvements in the compliance group (>360 minutes of ICT-PA use) (pre 58.5±11.7; post 62.7±12.9; p=0.002). The average program satisfaction score was 7.7±1.6 out of 10. Data are presented as mean±standard deviation.
Conclusion
The ICT-PA program effectively improved cognitive functions in MCI patients, with high satisfaction rates.
