Many people complain of tight hamstrings. In actuality, the tension is actually mostly from the ligaments of the pelvis. As you can see from the pictures the Dorsal Sacral ligament and the Sacrotuberous ligament are large powerful ligaments that can regulate the flexing (bending) of the leg forward. Also, you can see that the lower spinal muscles can be effected by tension here, causing low back pain. Many people will notice this when they try to touch their toes. For those that can touch their toes, they may not realize that they could still have tension in these ligaments. Many people compensate for tension in this area by flexing their rib cage instead. So if you try to touch your toes in front of a mirror you should be able to bend at the waist WITHOUT bending your spine and still touch your toes. If you can’t touch your toes this means you have a major deficiency in your normal body movement patterns which should be corrected as soon as possible. Even if you have never been a “flexible” person this should be addressed because this inability to flex forward will cause the person to compensate every time they bend forward.
Usually, with the combination of some of the following treatments normal flexion can be improved:
Low Force Chiropractic Adjustments
Active Release Treatments
