i believe if the knee is luxated out of place and not able to slip back in anymore this would be obsolete, but for those that do slip back into place this helps to heal the muscles that are strained and stretched around the knee and relaxes them so they are able to heal and stop pulling on the knee.
i will scan in everything i have on it soon!! also, it is not painful, she used all tools on my arm before using them on Sadie so i would know exactly what she felt. it was light as a butterfly and barely felt.
i'll also keep researching this for us. it's an amazing new thing and it actually can heal and help with MANY other issues.
