The pelvis and its associated structures (joints, bones, ligaments, tendons and muscles) play an important role in normal function of the spine & hips. The pelvis provides the bony link between the flexible spine and the lower limbs and a key function of a stable pelvis is to transmit forces and assist balance, it also provides attachment sites for over 35 muscles.
The joints of the pelvis i.e. the pubic symphysis and the sacro-iliac joints (SIJ) must be able to absorb and transmit forces efficiently for optimal function of the spine and the lower limbs.
Pelvic stability involves the integrated function of not only the joints and ligaments but of the many muscles which have either a direct or indirect effect on the pelvis. Pelvic stability is essential if forces are to be distributed across these different parts of the body and result in normal movement and function.
