“For your 4 year old mare, tying up, tight back end, do 10 minutes on 30/ 10 mins on 40/ 10 mins on 50 at least 5 times a week.
For your 7 year old gelding I would keep at the 30 and 40 hz but it needs to be for 30 mins total. I also have some insight as to why he could be “worse”. Many times we are helping the horse go through a major change by applying vibration to his body. This change is a positive one, however because there are literal physical shifts in how the horse is carrying himself, he may show slight soreness as he progresses onward to new and healthy body balance!
For your 5 year old gelding, sore shins after winning race last week, and needs more strength behind, so using 30hz for shins and 35hz for strength? Do this for at least 30 mins daily.
And for colic I think it’s best to do 20 hz for 20 mins or until the horse has some releases. Go to http://www.integratedequine.net/2015/08/16/good-vibrations-equivibe-therapy-session-for-horses for more info.”
