What is Max Flexion?

[Jakem]

What is heal to butt flexion in degrees for the average person?

What is the range that the middle 60% of the bell curve fall into when they are full heal to butt in flexion?  My guess is 145-150 degrees.

Jake, glad things still continue to go well for you.  My good leg, when seated and pulled to my rear, is at 142.  I also have a hypermobile patela on my good knee (5 on a 1-6 scale when 6 is dislocated).  Continued success!
