Feasibility and Preliminary Effects of a Pressure Sensor–Based Exergame on Cognitive and Sensorimotor Frailty in Low-Income Older Adults Receiving Public Community Care Services: Pilot Randomized Controlled Trial
Abstract
Background Age-related cognitive and sensorimotor declines co-occur and reinforce one another, increasing vulnerability to functional dependence and falls. Exergaming offers integrated cognitive-motor training, but most systems lack features that support personalized care for socially vulnerable, community-dwelling older adults. Low-income older adults receiving Public Community Care services bear a disproportionate burden of cognitive and sensorimotor decline, yet remain underrepresented in digital health research. As part of a broader program to develop a digital health monitoring-to-intervention framework, we evaluated a pressure sensor–based exergame designed to deliver targeted cognitive-motor training within the existing Public Community Care infrastructure. Objective This study evaluates the feasibility and preliminary effects of the Brain Step exergaming intervention on cognitive and sensorimotor frailty in low-income older adults living alone who were receiving Public Community Care services through a pilot study (study 1) and a randomized controlled trial (RCT; study 2). Methods Study 1 (n=15) was a 12-week single-arm pilot study. Study 2 was a parallel-group pilot RCT conducted in Seoul, South Korea. Thirty-one low-income older adults living alone who were receiving Public Community Care services (mean age 81.5 years; 26/31, 84%, female) were randomized to the intervention (n=16) or control (n=15) group. The 16-week intervention used custom hardware with…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 16 participants or records.
