Study Notes

The pelvis must provide stability and mobility during gait.
It offers a stable base for the lower limb and HAT.
The pelvis must be stable enough to transfer weight and move the acetabulum.
In the sagittal plane, the pelvis remains relatively level.
Two cycles of sinusoidal motion occur with each step.
Companion tilting of the pelvis occurs to provide additional motion at the hip.
The amount of pelvic tilt depends on soft tissue mobility and walking speed.
Assuming normal soft tissue mobility, pelvic tilt increases with walking speed.
