It is a simple bridge test that looks at the ability to activate the glute max as the primary hip extensor, with a minor contribution from the hamstrings, and a neutral lumbar spine. We don't want to see lumbar extension when trying to extend the hip. A proper activation strategy with this test is not a "good thing" to see but instead should be viewed as a necessity for athletes and perhaps the non-athletic population as well.
A person could have "strong glutes" and still fail this test if they don't know how to use them. Additionally, if a person failed this test and had weak glutes with manual muscle testing then it may be a waste to prescribe glute strengthening exercises when in reality they need to work on activation first.
What We Do Want To See/Feel:
- Neutral Lumbar Spine
- Stable Lumbopelvic control
- Patient to "feel" the effort come from their butt/glutes and hamstrings, Jay taught us 70% - 30% contribution, respectively.
- An ability to hold steady for 20-30 seconds with easy. It may be beneficial to do this for reps as well.
What We Don't Want to See/Feel:
- Hamstring "Cramping"
- Lumbar Extension
- Patient to "feel" the effort come from their low back
- Tilting/dipping/rotation of the pelvis when transitioning from double leg to single leg.
- Excessive Effort and/or Labored Breathing
- An inability to maintain the bridge position or excessive shaking while doing so
