What is the normal elbow flexion range of motion?

• A. 140-150 degrees
• B. 90-100 degrees
• C. 180-190 degrees
• D. 0-45 degrees

Answer: (A)

Normal elbow flexion is how far you can bend the elbow from a straight arm. In healthy adults, the elbow can typically flex to about 140 to 150 degrees. Full extension is 0 degrees, with a small amount of people having a tiny bit of hyperextension beyond that. So, 140–150 degrees reflects the standard range for bending the elbow, while options like 90–100 degrees are more limited, 180–190 degrees would exceed what the joint can do, and 0–45 degrees is near straight or only lightly bent. When measuring, clinicians use a goniometer with the patient in a neutral position to capture this full flexion range accurately.
