What is sway back posture?

How to determine if you have sway back posture

What’s happening with your muscles in sway back posture?

Common injuries associated with the sway back posture

The solution: The best exercises to fix your sway back posture

Ligament laxity:

... ligament laxity can cause sway back posture. Since the stability of the joints has been compromised, sway back posture occurs as it allows the weight of your body to rest on the excessive curves of the spine.

It is common for people to get confused between having a sway back posture versus having an anterior pelvic tilt.

The main difference being that with the sway back posture, the centre of the hips are in front of the line of gravity. With anterior pelvic tilt, the hips are generally stacked over the ankles.

It is important to know the difference between these postures as their respective treatments and exercises are different! Doing the right exercise for the wrong diagnosis will not help you.

Upper Body Posture

I. Faulty Postures in Side View: All three of the main types of faulty posture seen in side or lateral view — Flat Back, Sway Back and Kephotic-Lordotic —

Upper Body in 4 types of Standing Posture



Lower Body Posture:

2. Angle of hip and knee Joints

Backward bending (extension) of the hips and knees is usually limited, which gives stability to the body in standing position because you can't "buckle backwards" (Kendall et al.) But in Swayback Posture the hips and knees have a backward bend (hyperextension), causing the pelvis to shift forward ahead of the feet. To prevent the entire body from falling forward, the upper trunk shifts backward to compensate, see illustration below: Swayback Posture, third from the left:

Iliopsoas weakness may result in a “sway back” posture or “flat back” posture. As the line of gravity falls slightly posterior to the hip axis, it creates an extension moment at the hip. EMG studies have shown that in normal conditions the iliopsoas muscle is activated to create an internal flexion moment to counteract this external force. Prolonged hyperextension resulting from this sway back posture increases stress placed on the anterior hip joint ligaments and anterior joint capsule, which can lead to instability in the hip joint. This can also cause muscle imbalances due to overcompensation of surrounding muscle tissue.
