Introduction to Physical Agents for Physical Therapist Assistant (PTA) Practice Test

Body diagrams map where pain is felt. They provide a visual way for a patient to indicate the exact locations, distribution, and any radiation of pain on a body outline, which helps you identify patterns and plan treatment. This visual map also serves as a reference to monitor changes over time. While pain intensity and quality are typically captured with separate scales and descriptors, the diagram itself is specifically used to mark the location of pain. It won’t assess heart rate or skin color, which are evaluated through other parts of the exam.
