Mallenders and stumbling

[Big Pony]

( I did a post yesterday, as I wondered whether the scans on the back or Pos legs were mites, but I now think they are mallenders)
Po, who is coloured, with white legs and pink skin (not a cob, but a bit chunky) , has had scabs on the back of both his knees since I bought him ( a year and a bit ago) . They have recently gone a bit further down his legs, and he has fallen over twice in two weeks when he has been ridden. I read that mallenders can cause stumbling, and wondered if anyone has experienced this, as this is not like him! Also does anyone have any treatments?

i dont think mallenders and sallenders is anything more than a very annoying skin disorder -treat it like psoriasis ,keep it moisturised and soft and that will help keep the scabs at a minimum
