Which term is used to describe the energy cost of physical activity in rehabilitation planning?

• A. MET
• B. SpO2
• C. PVCs
• D. Orthostatic

Answer: (A)

Metabolic equivalents describe the energy cost of physical activity. A MET is a unit that compares the oxygen used during an activity with the oxygen used at rest, roughly resting metabolic rate. This makes METs a practical way to quantify how hard the body is working during different activities and to plan a rehabilitation program safely. In rehab, you can estimate how intense an exercise is by its MET value and pace progression accordingly—for example, classifying activities as light, moderate, or vigorous helps determine duration, frequency, and progression. Other terms listed don’t measure energy cost. SpO2 reflects blood oxygen saturation, not how much energy a task requires. Premature ventricular contractions (PVCs) are a type of heart rhythm irregularity. Orthostatic refers to changes in blood pressure with posture, not the metabolic demand of activity. Thus, MET best describes the energy cost of physical activity in rehabilitation planning.
