Validation of the feasibility and usability of a mobile technology-based functional game to improve the cognitive function of community-dwelling older adults living with MCI.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: With dementia cases increasing worldwide, the demand for creative and accessible strategies to support cognitive health in at-risk older populations has become urgent. Mobile applications offer a valuable method for promoting cognitive wellbeing, particularly for independently living older individuals with mild cognitive impairment (MCI). Objective: This preliminary study evaluated the feasibility and usability of a mobile-based cognitive training game among older Korean adults diagnosed with MCI. Methods: A single-arm experimental design was adopted with 40 participants aged 65 and above who met eligibility criteria on the Korean Mini-Mental State Examination (K-MMSE). Participants used the Descartes Care application three times a week for 12 weeks. Feasibility was assessed through changes in game scores and completion times, while usability was evaluated using participant satisfaction, efficiency, learnability, safety, and intention to reuse. Results: Thirty-eight participants completed the study. Significant improvements were observed in 69% (18 of 26) of mini-games for performance and efficiency ( Conclusions: Findings support the feasibility, safety, and acceptability of mobile technology-based cognitive training for older adults with MCI. This intervention shows promise as an accessible, engaging tool for cognitive health promotion. Future randomized controlled trials are needed to validate efficacy and assess long-term outcomes.
