What does the Bowstring Sign help differentiate?

• A. Patellar tendinopathy from quadriceps strain
• B. Sciatic pain from hamstring involvement
• C. Hip flexor strain from gluteus medius weakness
• D. Meniscus tear from ligament injury

Answer: (B)

The Bowstring Sign is a clinical test primarily used to assess the involvement of the sciatic nerve and its relationship to the hamstring muscles. When the knees are flexed and the hip is flexed while applying pressure to the back of the knee, reproducing pain or discomfort indicates that the issue may be related to sciatic nerve irritation, which could involve specific hamstring muscle pathology as well. This test is particularly beneficial in differentiating between sciatic nerve pain and pain that arises exclusively from hamstring issues. By utilizing the Bowstring Sign, clinicians can gather crucial information regarding whether the discomfort originates from the sciatic nerve being compressed or irritated due to hamstring tension, or if the issue lies solely in the hamstring muscles themselves. In cases where pain is reproduced specifically with the Bowstring test, it supports a diagnosis that implicates sciatic nerve involvement, aiding in the overall assessment and management plan for the patient.
