The pelvis and pelvic instability

The pelvis is a magnificent structure of the body, essentially it acts as a base for limbs to move off. So why is it important in physiotherapy and what really is the IMPORTANCE of its function?


-       It is the connection between the upper and lower parts of the body

-       The pelvis houses key essential organs (e.g. intestines, urinary structures and sexual organs)

-       Key muscles of the pelvis include- Pelvic floor muscles, internal oblique’s, transverse abdominus, gluteal, hamstring and the psoas muscle groups

-       These key muscles are used to support the weight of the body, allow weight transference into the limbs, joint mobility and support the spine and trunk


So what is pelvic instability?


Pelvic instability refers to a movement-based pattern that is altered, causing the in-coordination of muscles of the pelvis and trunk that usually provide stable base for weight transference, mobility and general posture.


How can physio help?

-       By making a physio appointment we can do a thorough assessment and set up an indiviualised program to help get these motor patterns working again and suited to YOUR goals

-       Body awareness is key. If you notice any movements you struggle with, have a think could it be coming from your pelvis?

-       Undertake regular stretching of the big muscle groups of the lower limbs


I have treated many patients who present with pelvic instability. Their goals were generally to feel more stable and prevent injuries, specifically to the ankles, knee and lower back. By understanding their movements and the importance of the pelvis, we were able to work together to achieve THEIR goals.
