hey everyone it's sarah stanner sorry and calm and in this video you're going to see a demonstration on how to check for clonus in our previous review we talked about preeclampsia and - the things that we stressed in that lecture was that we needed to check for hyperreflexia and clone a specifically ankle clonise because if those two things are present it indicates that our central nervous system is really stressed out and irritable and there's a risk for seizures so let me show you how to check for clonise and what a positive result looks like first of all you want to do is you want to have the patient's setting and dangling their feet then you're gonna take your hand and you're going to support the lower leg that you want to test and you are going to dorsiflex the foot so I pointed upwards quickly and look for the response and then let it go and that's a normal response that would be a negative clonus a positive clonus you do the same thing you're gonna quickly dorsiflex the foot and you're gonna look for its response a positive response would be that the foot starts to bounce or be at least three or more times and that would be considered a positive clonise okay so that is how you check for clonise and don't forget to check out our other reviews in this maternity series
