The condition causes hip flexors, quads, and lower back to tighten up and become overactive. Glutes, and hammies become dormant and it gets tricky to activate them so the quads and back take over.
Lunges, bridges, and deep squats strengthen glutes and hammies and get them firing again. The foam roller is used to relax and lengthen the quads, hip flexors and lower back.
If you're really curious about it I can post some links with a lot of information.
