Description: During a physical therapy session, a patient attempts a set of three elbow extension exercises. Upon completion of the three exercises, her therapist provides her with feedback concerning the numerical angle of elbow extension achieved on each of the three exercises. What type of feedback did the therapist provide?

Key Concepts

Intrinsic vs Extrinsic Feedback

Intrinsic feedback is the sensory information a person naturally receives from their own proprioception during movement, while extrinsic feedback, also known as augmented feedback, is supplied by external sources. In this scenario, the therapist’s numerical feedback represents extrinsic feedback, as it offers additional details not immediately available from the patient’s own sensory systems.

Augmented Feedback

Augmented feedback is additional information provided by an external source, such as a therapist or coach, after a movement or skill has been performed. It supplements the intrinsic sensory feedback that comes from within the body, offering precise, objective information that can help refine performance and correct errors.

Knowledge of Results

Knowledge of results refers to feedback that provides information about the outcome of a performance relative to the goal. In the context of physical therapy, offering a numerical value such as the angle of elbow extension falls under this category, as it specifically tells the patient how successful the movement was in achieving its intended outcome.
