Robot-based Intervention to Improve Physical Activity in Older Adults

Plain-language summary

Physical inactivity is considered a global pandemic negatively impacting the health of over 60% of older adults in America. Interventions aimed at improving physical activity in older adults focus on training reflective processes such as providing information on health benefits of physical activity. These interventions generally find that participants improved their intentions to be physically active rather than supporting actual change in behaviours to become physically active. There is growing support for the idea that human behaviour is the result of a combination of quick automatic processes and slower reflective processes. Interventional studies have used cognitive bias modification tasks that target the quick automatic processes to retrain participant's bias. Such studies find that participant's bias towards diet, alcohol, and phobias can be altered using these cognitive bias modification tasks. In this study, the investigators developed a new training task using a robotic device that aims to retrain automatic bias towards physical activity and sedentary behaviours. The robotic device allows greater immersive environments for participants to interact with and be more engaged with the cognitive bias modification task. This interventional study is testing whether this new robot-based training and the protocol for assessing physical activity is feasible for retraining older adults' bias towards physical activity and sedentary behaviour. Participants will be examined on their daily physical activity using an accelerometer, their physical ability using functional tests, and their perceptions on physical activity using questionnaires. To determine whether this protocol is feasible, the investigators will examine participant recruitment and retention rates.
