Ok, so ill give you all the best update as i can. About 3 months ago, my mare rolled into her panels and was down all night in the rain. My parents found her the next morning, just about on her death bed. I was in hawaii at that time. She had abrasions on the front of her pasterns, assuming they came from trying to get up. I got home about two months later, and the abrasions were still there. Fast forward to june 13th...we took her to oregon state university to be seen by the vet and students there. All of her blood work was fine, her cardio exam seemed normal, she was not sore anywhere on her back or hips, and she checked out clean on neurological problems as well. But, she did score a 2 out of 5 in the lameness exam due to being lame in her back legs, mostly her right hind. And she does have some swelling on her rear tendon sheaths, but that could just be normal for her. There was something about her eyes that suggested vitamin e and selenium deficiency. Other symptoms of that are muscle tremors, muscle wastage, irregular stance, and an abmormal gait...all of which she has!! We ruled out seizures as well. The only thing left is a pretty extreme case of sleep deprivation. A horse can go a couple days without falling into REM sleep, but they must eventually get it. A horse must lay down for REM sleep, because their motor skills (like standing) must all stop. If a horse refuses to lay down for some reason, eventually their body will go into REM while standing, but their motor skills will stop, causing them to collapse. So, we are going with the unofficial diagnosis of sleep deprivation. Heres what we think happened....she scared herself by getting hung up in the panels, so she refuses to lay down in her pen. This has probably been going on for the last three months, its only obvious because it has gotten progressively worse. She was moved to a full barn with a large stall and lots of shavings. She is on bute for pain and we started her on 15mil of Ace, three times a day to try to get her to go down. She was laying down and sleeping out at this barn, so we cut her back to just getting Ace at night, to help her re-develope a sleeping pattern. Worse case scenario, we would have had to completely knock her out and drop her. This would've basically reset her whole sleeping pattern, but it does work. She is now back home, and in a different pen. She had shavings on her back, side and in her mane this morning. All of her wounds have began healing up. The night after we got her back from OSU, with the diagnosis of sleep deprivation, I stayed in her pen and video taped her. The videos are hard to see, but it was SOO obvious watching. Every time she went to rest, her legs would give out on her. Never thought sleep deprivation could cause such a serious problem in a horse. But it's that, along with the Equine Motor Neuron Disease (EMND.) Long winded!!!! Thank you Jesus its nothing too serious!!! and Thank you all for helping!!! I will try to get one of the videos on this thread to show you what I'm talking about.
