How Can Specialist Seating Correct Pelvic Rotation?

In this article we explore the problem of pelvic rotation and learn how specialist seating can help resolve this issue.

What is pelvic rotation?

Pelvic rotation is a postural problem in which one side of the pelvis is further forward than the other. It’s important to note that this means that one hip is further forward, not necessarily higher or lower than the other (this is pelvic obliquity although the two conditions often go hand-in-hand).

In this diagram, the right ASIS is further forward than the left. This is called left pelvic rotation.

You can assess the position of a person’s pelvis by feeling for their ASIS (anterior superior iliac spine) points. These are the bonier bits at the front of the person’s hips, and once you have found both, you can judge their pelvic positioning.

If you find that the person’s left ASIS is further forward, this is referred to as right pelvic rotation. Conversely, if the person’s right ASIS is further forward, this is called left pelvic rotation.

What causes pelvic rotation?

Pelvic rotation can be a sign of many things including asymmetrical leg length, hip flexion, or hip adduction. These can all cause the pelvis to twist to compensate for the positioning.

It is important to note that as with all postural problems, pelvic rotation is not a linear chain of cause and effect.

The problem is more a continuous circle of cause and effect, where if a combination of factors are present these cause issues which then further the problem if they are left unchecked, and thus the cycle continues.

This self-fuelling ‘vicious circle’ can be reversed by removing the root causes and using the right specialist seating and postural techniques.

causes and effects of pelvic rotation

In terms of poor seating, pelvic rotation can also be caused by a lack of backrest support or too wide a seat. As you can imagine, sitting in a chair too wide can lead you to twist and rotate your pelvis to find a more supported position.

It’s important to combat pelvic rotation wherever possible because it can lead to more severe postural problems and back pain.

What should I look for when buying a chair for someone with pelvic rotation?

It is possible to help rectify or alleviate pelvic rotation with specialist seating. Chairs for people with pelvic rotation will need to be well-sized to the client to give them the best possible outcome.

The seat width is one of the most crucial measurements in the chair because it helps to secure the person’s pelvis in a level, supported position. This, in turn, will prevent the pelvis from rotating any further and it could help get it back to a healthier position.

Lento care chair seat width

The Lento care chair has adjustable seat width so you can change the chair to match the person’s pelvic positioning if it changes over time.

For this reason, we would highly recommend a chair with built-in seat width adjustment like the Lento care chair. This means that you can change the chair to suit the person’s needs as they change over time.

Another thing to consider in chairs for people with pelvic rotation is having equal thigh support. This will help to keep the person’s hips level and prevent the rotation from extending any further.

If the client has leg length discrepancy, you may need to take a closer look at footrest options to ensure that they are getting equal support with either leg.
