I have not been alone in saying for some years now "movement is key". I guess it´s good to have it confirmed by someone with a title! Movement is what generates circulation, which generates new cell growth, which of course speeds up the new, healthy growth of a correctly attended and ailimented hoof. Movement, even though at times your horse may appear to struggle, is exactly like the physiotherapy a traumatologist would recommend to you, dear human, when you have suffered a lesion, or broken bone. You have to push through the pain. You have to ask ´more´ in order to recover, and the more you ask, the quicker your recovery.
I totally understand it can be difficult, watching your beloved equine struggling to put one foot in front of the other in severe cases, but, within reason, this is what must be done. Of course we have boots and pads to make that physio more comfortable. But it must also be remember by many, just as when you have an injury, that initial crank-start each day can be stiffer and slower, until a body/limb warms up and finds more ease of movement. You have to help your horse push through this. You must accept your EP´s guidelines, if you are rehabilitating at home, and follow instructions with regard to exercise and turnout. The more consistent you are with movement, the sooner your horse is dancing again.
