To Demonstrate Ankle and Patellar Clonus On a Subject

December 4, 2016 by Admin Leave a Comment

Clonus:

When deep reflexes are exaggerated, the phenomena of clonus is elicitable. Clonus indicates upper motor neuron lesion and is indicative of hyper-reflexia. In anxoius persons the clonus is unsustained. The examples of clonus are:

  • Ankle clonus
  • Patellar Clonus

1. Ankle Clonus:

The knee of the subject is slightly flexed along with the hip joint. Held the anterior part of foot with other hand. Give two or three dosriflexion sharp movements to the foot. Then sustained pressure on the side of foot in dorsiflexion position is maintained. A series of contraction of muscle and ankle joint movements are seen when the ankle clonus is positive.

ankle and patellar clonus

2. Patellar Clonus:

The subject is asked to lie supine. Tendon of quadriceps femoris muscle is held at the upper border of patella. Two  to three sudden jerks are given downward to stretch  quadriceps femoris muscle. Then stretch is sustained. A series of contractions of the quadriceps muscles occur and we call it that the pattelar clonus is positive.

ABO and RH Blood Grouping

Our blood is classified into different blood groups and the basis for the differentiation between these groups are the substances such as antigens whose absence or presence determine a different blood group. Every blood group has its different plasma which is another base for differentiation in these blood groups. A person with one blood group […]

Differential Leukocyte Count Procedure And Results

You know from one of our previous articles that white blood cell count or total leukocyte count is a test which we perform to get the count of white blood cells in our blood. With the help of this test, we find the different ranges of leukocytes presiding in our body and if there are […]

Creatine Kinase Test by IFCC Kinetic Method:Principle, Procedure, Results

We have been doing different determinations by Kinetic UV method on our website. Today, our objective is the Creatine Kinase Test by IFCC Kinetic Method. Creatine kinase is basically an enzyme which is mostly present in heart muscles and skeletal. The formation of this substance happens which two subunits which are from muscle and brain […]

Osazone Test: Principle, Procedure, and Results

In the field of chemistry or medical sciences, one of the most common tests which is performed in biochemistry labs is Osazone Test. It is a normal routine test in order to identify the sugars. In this test, as the name indicates, osazones are involved and if you don’t about this substance, we will like […]

Lactate Dehydrogenase Test: Principle And Procedure

Before we estimate Lactate Dehydrogenase, we need to know why it is important. The reason for doing anything must be mentioned and that’s why need to know the reason first. Well, lactate dehydrogenase has many uses especially clinically. When tissue damage happens, the increase of this enzyme is one of the reasons behind it. This damage […]
