Objectives: The purpose of this study is to investigate attentional (internal vs. external) focus effects on persons with amputation to perform a defined compensatory movement to reduce the likelihood of a fall. An internal focus of attention directs a person's conscious attention to their body's movements, whereas an external focus of attention directs a person's conscious attention to the effects of their movements or specific features in the environment. Numerous experiments have investigated the effects of an internal and external focus of attention on motor performance and the findings are in favor of an external focus of attention. In our work, we propose a motor learning research experiment to evaluate attentional focus strategies on the rehabilitation outcomes of learning and adaptation to the new proprioceptive information for persons with a recent transtibial amputation.
