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.
