What does multiple positive findings on the Van der Wurff cluster indicate?

• A. Lower likelihood of nerve root involvement
• B. No diagnostic value
• C. Pain in unrelated area
• D. Higher likelihood of nerve root involvement

Answer: (D)

When a cluster of tests is used, each sign adds information about whether a nerve root is being irritated. If several components of the Van der Wurff cluster are positive, it increases the likelihood that nerve root involvement is present. In other words, the more positive findings you have within this cluster, the more you can suspect radiculopathy rather than unrelated pain or another issue. This doesn’t prove it with absolute certainty, but it does raise the probability and helps guide further evaluation or treatment.
