In a clinical test, the Andersson Link is evident. If a patient has poor hamstring flexibility, the link is under constant tension. This causes the sacrotuberous ligament to pull the sacrum into excessive counternutation (backward tilt), which flattens the lumbar lordosis and shifts stress to the lumbar discs.
If you have identified an Andersson Link dysfunction, here is a tiered approach to fixing it. andersson link
The Andersson Link is more than just a textbook term; it is a functional bridge between the back and the leg. As imaging technology (dynamic ultrasound and real-time MRI) improves, we are likely to see even more evidence supporting how hamstring tension directly modulates sacral motion. In a clinical test, the Andersson Link is evident
For clinicians, the lesson is clear: You cannot treat the low back without assessing the hamstring, and you cannot treat the hamstring without assessing the sacrum. low back pain
If you suffer from chronic low back pain that clicks, shifts, or feels unstable, ask your physiotherapist about the Andersson Link. It might be the missing piece of your rehabilitation puzzle.
