Question

Quizplus · Accepted Answer

During mid-stance, the gluteus medius bears the primary responsibility for controlling the pelvis in the frontal plane. This muscle contracts to prevent your hip from dropping down towards the ground, maintaining your balance as your body weight shifts over your stance leg. The piriformis is involved in external rotation of the hip and is not primarily responsible for controlling the pelvis in the frontal plane during mid-stance. The gluteus minimus is a smaller muscle located beneath the gluteus medius and also helps to stabilize the hip and pelvis during weight-bearing. While the gluteus maximus is a powerful hip extensor, it is not primarily responsible for controlling the pelvis in the frontal plane during mid-stance.
