Final answer:
The clinician needs to make several choices when using the GRoC (Global Rating of Change) scale, including determining the total distance traveled, displacement, and when to use each measurement.
Step-by-step explanation:
The clinician needs to make several choices when using the GRoC (Global Rating of Change) scale:
- Which measurement is considered the total distance traveled?
- Which measurement represents displacement?
- When should one measurement be used over the other?
In response to these questions, the choices include:
- The total distance traveled is the overall magnitude of change, while displacement is the direction and magnitude of change.
- The clinician needs to determine whether the overall distance traveled or the direction of change is more relevant to the specific case at hand.
- One may choose to use the total distance traveled when evaluating progress, while displacement might be more important when considering direction and significance of change.
