Elbow flexion range is how far you can bend the elbow from straight. In a healthy adult, the arc goes from 0 degrees (full extension) up to about 150 degrees of flexion. That near-maximum bend is what’s typically considered the normal flexion range, though individual variation exists (some people reach around 140–150 degrees, others a bit less or more depending on anatomy and measurement). So 150 degrees reflects near full flexion and is the best choice for normal elbow flexion. Choices like 90 or 120 show partial flexion, and 180 would imply hyperflexion beyond the usual full range.
