A lot of horses with physical discomfort and defects or injuries benefit from Straightness Training. Because we always use ST to strengthen their strong parts to support the weak parts.
Most of the time ‘rest rust’, that’s a Dutch saying, because when you don't use it, you lose it, because it gets rusty. The same applies to the horse; When you also don't use his strong parts either he will get even weaker.
Most guidelines on how to train an arthritic horses also apply to horses with other kind of issues.
But make sure to always discuss the possibilities for your horse with your veterinarian.
