I dont think he scored me in the traditional FMS way. However he did mention I did really well during the assessment which is unusual as I have knee pain and from the report he gave it seems like I did well on mostly everything (hip capsule being the only noticeable thing). All tho 3-D gait analysis showed trendelenburgs sign with a left pelvic drop. So my right glute medius isn’t firing atleast when performing functional activities because I do feel it firing during the clamshells. 

Holding the clamshells (isometric) and preventing the leg for adducting can accomplish some of the reactive neural training. But I do agree X-band walks are better for this purpose. Another good one is squats with band around the knees trying to push the knees in while you maintain an external rotated position activating the glutes to prevent your knees from collapsing.

I do have pain still.
