Serious games in prevention and rehabilitation—a new panacea for elderly people?

Digital games cannot only be used for fun and entertainment. The term “serious games” (SG) denotes digital games serving serious
purposes like education, training, advertising, research and health. Recently, a new generation of games has emerged involving
whole-body movements. Compared to traditional interventions, these games may help elderly people to improve their health by
enhancing physical fitness and coordinative abilities by combining increased motivation, game experience like fun and game
flow and training. Serious games, particularly adventure and shooter games, already play an important role in health education,
prevention and rehabilitation, e.g. to enhance health-related physical activity, improve sensory–motor coordination, prevent
asthma, change nutrition behaviour and alleviate diabetes and prevent smoking or HIV. In this paper, the impact of SG on prevention
and rehabilitation is discussed. Three criteria are applied. Beyond effectivity and efficiency, the additional benefits of
serious games can be described and explained by different models including social, psychological, physiological and sensory–motor
factors. The quality of study serves as a third criterion. Despite first promising results, there are only few high-quality
studies. Adequate content, game interfaces, sustainability and appropriate settings are critical factors for the success of
SG. In this regard, (sport) science can help to develop and evaluate SG and test appropriate settings that ensure sustainable
use of serious games.
