To Demonstrate The Power Of Different Muscles Of Subject

November 20, 2016 by Admin Leave a Comment

Testing the power of Muscles of Upper Limb:

To Demonstrate The Power Of Different Muscles Of Subject

Abductor pllicis Brevis:

The patient is asked to abduct his thumb is a plane at right angle to the palmer aspect of the index finger, against the resistance of the examiner’s own thumb. The muscle can be seen and felt to contract.

Opponens Pollicis:

Ask the patient to touch the tip of his little finger with the point of his thumb. Oppose the movement with your thumb or index finger.

Interossie and Lumbricals:

Test the patient’s ability to flex his metacarpophalangeal joints and to extend the distal interphalangeal joints. The interossei also adduct the fingers.

Flexors of Fingers:

Ask the patient to squeeze your fingers. Allow him to squeeze only your index and middle fingers. This is sufficient to assess strength of grip without his painfully crushing your fingers.

Flexors fo the wrist:

Ask him to bring the tips of his fingers towards the front of the forearm.

Extensors of the wrist:

Ask the patient to make a fist, and try to forcibly flex the wrist against his effort to maintain his posture.

Brachioradialis:

Place the arm of the patient midway between the prone and supine position then ask the patient to bend up the forearm, whilst you oppose the movement by grasping his hand.

Biceps:

Ask the patient to bend up the forearm against resistance, with the forearm in full supination.

Triceps:

Ask the patient to straighten out his forearm against your resistance.

Supraspinatus and deltoid:

Ask the patient to lift his arm straight out at right angles to his side against resistance. The first thirty degree of his movement is carried out by the supraspinatus and the remaining sixty degree is produced by the deltoid.

Testing the power of muscles of trunk:

Muscles of Abdomen:

Weakness of these muscles is shown by the patient’s inability to sit up in the bed from the supine position with out the aid of his arms.

Trapezius:

Upper part: Ask the patient to shrug his shoulder against examiner’s resistance.

Lower part: Ask him to approximate to the shoulder blades.

Testing the power of muscles of limb limbs:

Dorsiflexion and planter flexion of the feet and toes are tested by asking the patient to elevate or depress the part against resistance.

Extensors of the knees:

Bend up the patient’s knee and then pressing up with your hand on his skin, ask him to try to straighten it out again.

Flexors of the knee:

Raise the legs up from the bed, supporting the thigh with your left hand and holding the ankle with your right hand. Then ask the patient to bend his knee.

Flexors of the Thigh:

With the leg extended ask the patient to raise his leg off the bed against your resistance.

Adductors of the thigh:

Abduct the limb and then ask the patient to bring it back to the midline against resistance.

Abductors of the thigh:

Place the patient’s leg together and ask him to separate them against resistance.

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 […]
