Hi Sandy,
Your mare will tell you when she's ready to move around. The thing is, you want to control her movement! You dont want her to undo any tight laminae that she's already grown.
Lets start at the beginning.....DDT/E. Diagnosis by bloodwork. Diet being low esc/s. Trim a balanced foot with low heels and toes backed. Exercise if the horse is able.
You've started the ER Diet. This reduces sugar. Is she IR? Cushings? or both? Have you done bloodwork? Is her trim correct? Can you still feel a digital pulse? Still sore? Can you open the stall door to a small paddock/drylot? Give her the option of movement and watch what she chooses to stand on. Is she in pads/boots now? Can you put a quiet horse in with her in a dry paddock to keep her company? one that wont chase her around or push her out of her hay? IF the answer is no and she's not on bute you may be able to handwalk her at her pace in long flowing lines (no corners, tight turns or pivoting) for a few minutes a day. IF she prefers to lay down in her stall and just rest, let her!
Watch her and she'll tell you what she needs.
