As insurance continues to reduce physical and occupational therapy visits and patient co-pays continue to escalate, patients and providers alike demand more rapid outcomes in therapy. Without question, therapeutic exercise progression is the hallmark of physical and occupational therapy prescription. It is imperative that the therapist have a sound rationale for exercise progression to maximize patient outcomes, whether it is a pediatric or geriatric patient or a high-level athlete. In order to do that, a review of foundational principles of resistance exercise is warranted. Next, a proper understanding of rehabilitation objectives--endurance, strength, and power--will enable the therapist to understand how to appropriately progress a patient. Furthermore, the therapist will understand how to manipulate training variables like load, rest periods, set structures, and repetition schemes to promote variability in program design, maximize treatment sessions, and minimize the risk of boredom and plateaus. This course provides a framework for progressing patients with upper and lower extremity conditions as well as how to appropriately test progress with evidence-based outcome measures.
