Also in the vet section but I know Tack Room gets the most traffic...

Following on from my post about feed causing sore feet (I’m feeding the wrong thing for something bare in behind so I’ve got a new low starch high oil plan)…

Please bear with me. This is long…

Bought my horse (17.2hh 7yr old DWBxISH gelding) Feb 2012. He has mild, what I was told to be, stringhalt in both back legs, although more prominently in the off-hind. It shows in walk as a slight swing outwards. Occasionally he raises is up and out. Absolutely no sign of it in trot or canter and he jumps happily. It’s also intermittent so sometimes not visible at all.

I work him like any other normal horse (schooling, jumping, hunting, XC etc) and he never has any issues. I do get the odd comment from people about his leg swinging out. I’m sick of saying “he’s got stringhalt” as I’m sure everyone with a horse the same is .

He’s as fit as a fiddle and could go all day. This is my first winter with him and I’ve been struggling with his weight. He held weight well and looked fantastic in the summer so I’m thinking the lack of condition is nothing to worry about and I’m expecting him to pick up when the grass comes through.

Now when I bought him I got his back shoes off (he’s still shod in-front) which I do with any horse I get as I find they do well (and saves some pennies). His back feet are solid and haven’t needed rasped since I had them taken off. He’s always been a bit of a verge hugger when it comes to stony ground and over the last few months has taken to not even liking to walk on smooth tarmac (although in trot he’s fine). I spoke to my farrier about it and he said that the constant wet ground wears/washes away the protective layer on the sole and can make them sensitive. Anyone heard of this?

So - mild stringhalt and a bit foot sore, more so in the last few months. He seems to suffer a more with the stringhalt (if that’s what it is!) in the cold when he’s standing all day/night at the big round bale of hay eating and not moving about.

So I was hacking him out on Friday. He came in from the field again sore on the stoney track. Off we went trotting the majority of the 4 miles to the woods. He was happy as larry and needed no encouragement to trot. We cantered round the tracks in the woods, back out onto the road and trotted the majority of the 4 miles back. Again no problems. So about 15 mins from home I did a bit of schooling along the road (quiet country tarmac road) e.g. leg yielding and transitions. He was feeling great. All of a sudden about 5 mins from home when I asked him to walk he suddenly started lifting his back right leg right up and out much more severely than he’s ever done! He was really struggling to walk and then got kind of stuck. I sat quietly waiting for him to pull out of it. He couldn’t. I jollied him up and pushed him out of it into trot and off he trotted no bother. I asked for walk again and the same thing happened (right back leg up and out to the side and he felt stuck). Again I pushed him into trot and off he went.

Took him home, gave him his tea and turned him out.

I gave him Saturday off. I took him out again yesterday and he felt the same. Awful in walk. Right leg up and out and really struggling but fine in trot. Took him into a grass field and all of a sudden he was absolutely fine in walk. We had a trot and canter round and he was right as rain and full of the joys.

So on the way home I experimented and every time I put him on the verge in walk (which he wanted to go on anyway) he felt right as rain. The moment I put him on the road (smooth tarmac) the back right leg started it’s swinging and a couple of times like he was going to get stuck again.

I am absolutely stumped on this one….

Sorry for the really long winded post. Just wanted to give as much info as possible.

I have a video of his normal gait and how he is just now (no idea how to upload them)
 
To me that doesn't sound like a typical stringhalt. It's possible it could be something else, locking patella springs to mind. If it continues I'd be tempted to get the vet to take a look
 
Sounds like an upward fixation of the patella. Please don't 'push' him out of it. Allow him to do it in his own time.

It's worth getting your vet to diagnose officially so that you can discuss options and future management.

The dropping of condition would also concern me.

Sorry cant view the vid for some reason.
 
Can't see the video but also sounds like it could be a stifle problem to me. Might be worth sending your vets a video to see what they think? That's what I did when my mare had a slipping stifle
 
he looks very bad in the video, but i am sorry i fail to see how you could continue to ride and jump a horse thats swings its leg out in walk without a vets diagnosis just a 'we think its stringhalt', you have had him for over a yr, people have commented on his gait, you were aware of it but not had a vet look at him
 
I've seen the vid, doesn't look like upward fixation of the patella to me (but I'll stand corrected), I would expect more toe dragging and not the swing out to the side. How odd that it became so exaggerated on the hard track, quite extreme at one point. I'd get the vet out in any case.
 
Stringhalt is caused by nerve damage and that would make sense with what you have described.

Worse in cold weather and on hard surfaces I would presume there is more "jarring".

You need the vet to have a look at him whilst it's so bad.
 
I'm definitely going to get the vet out to see him.

It's never been like this in the year i've owned him. It's always been a very slight intermittent swing out of the hind leg. He's always 100% sound in trot and canter and often in walk there is no sign of the swing. It has me so stumped that it is not there on soft ground yet on the hard it's very prominent.

Thanks for looking guys.
 
On the locking stifle/upward fixation of the patella. It happened one of my young ones and the vet said it can happen young horses when they lose a lot of condition. Reversing him got him working back fine. However he was stuck, he couldn't trot out of it. He was only a 4 yo just on work, so not as strong or established as your lad. He is coming 6 now and hasn't had it since. Which makes me think stringhalt for yours. It happened my lad in the field and surface didn't matter. Yours looks like locking stifle but trotting out of it and the difference in the vid verge v tarmac makes me think the stringhalt is exacerbated by the footiness. I could be completely wrong though. (probably am!)
Kauto Star has mild stringhalt at walk so your lad in good company!
 
Just another wee note...

He's not just dropped condition. When I got him Feb 2012 he looked quite poor. He picked up as soon as the spring grass came through. He looked very well all spring, summer and autumn. He dropped condition once the grass stopped growing in winter. From what i've seen of him so far he's going to be a typical hard keeper in winter and will naturally do well on good grazing (if it ever makes an appearance under all this snow).
 
Blimey that is quite a swing and I don't think I'd push him on either. I have known a horse with quite a pronounced stringhalt but nothing anywhere as dramatic as this - agree that the vet is your first option. I'll be interested to know what the result is. Good luck - they are such a worry aren't they.
 
Hey guys

Finally getting back to anyone interested in what the vet said about my horses strange hind leg movement.

I got the top Aberdeenshire horse vet out who specialises in lameness, and he didn't know what it was!

He said it was not stringhalt as that is a forward and stamp motion (rather than a swing out to the side. He also doesn't think it's shivers or EPSM. He put him on a 10 day course of anti-biotics to rule out inflammation in the top of the pelvis. They had no effect.

He did a heap of tests and assures me that he's in no pain and to carry on with him as I have been i.e. using him as a normal horse.

He took a heap of video and is sending it off to a couple of professor collegues and will get back to me. He said we could spend months doing test after test and still find nothing, and as he's more than capable of doing what I want him to do happily and comfortably (low level SJ, hunting, small ODEs etc) then there's no point throwing all that money at him.

So i'm just waiting to hear what these professors think.

Basically no further forward, and that'll be nigh on £200 please :s
