Observe a homemaker or worker doing an activity that requires pushing, pulling, reaching, lifting, or some other repetitive pattern. Analyze what component motions are part of the total pattern and decide if strength, range, endurance, balance, or coordination (or a combination) is necessary in the upper extremities, lower extremities, and trunk. Decide what is necessary to make the spine safe while doing this activity and design an exercise program that encompasses all the components. rather than an HVT technique? What are some situations in which you would perform an HVT technique rather than a manipulation technique?
