As part of the training process, the therapist may direct the patient's focus of attention away from an internal body-oriented focus (the feet or upper body movement) to an external focus that is directly related to the goal (avoiding obstacles on the floor). For example, the learner's focus of attention can shift as muscle strength, motor control and skill increase. In walking it may shift from the feet to the surrounding environment; the star billing for sit-to-stand may change from initial foot placement backward and increasing the speed of forward rotation of the upper body, to the need to steady a glass of water while standing up. Some recent findings with healthy subjects have shown what a difference it can make to performance and skill development if the learner directs attention toward the effect of the movement (an external focus) instead of to the movement itself (an internal focus)65.
