Which outcome measure captures a patient’s overall perceived change in condition?

• A. Global Impression of Change
• B. Pain Threshold
• C. Muscle Strength Grade
• D. Serum biomarkers

Answer: (A)

Global Impression of Change is a patient-reported measure that asks the person to rate their overall sense of improvement or decline since starting treatment. It captures a single, overall judgment that combines changes across multiple aspects—pain, function, daily living, and well-being—into one global perception. Because the question is about how the patient feels their condition has changed overall, this type of measure best reflects that subjective, holistic view. In contrast, Pain Threshold is a physiological test of how much stimulus is needed to feel pain, which doesn’t summarize overall change. Muscle Strength Grade provides an objective rating of muscle force, but not the patient’s global sense of improvement. Serum biomarkers are lab-based indicators of biological processes and do not directly measure the patient’s subjective sense of change.
