Jobe test: exploration and diagnosis of the supraspinatus muscle

The supraspinatus muscle is located in the shoulder region and there are various injuries that cause pain in it. For this reason, there is a test, known as the Jobe test, commonly used for the diagnosis and exploration of the supraspinatus muscle, which also allows for a simple evaluation of whether there is any injury to the supraspinatus muscle. In this post we tell you everything you need to know about the supraspinatus muscle, what its most common injuries are and how to perform the Jobe test correctly.

What is the supraspinatus muscle?

The supraspinatus muscle is located on the back of the shoulders and originates in the supraspinous fossa of the scapula, inserting in turn into the greater tubercle of the humerus.

This muscle is part of the rotator cuff, as are the infraspinatus, teres minor and subscapularis.

Function of the supraspinatus muscle

The supraspinatus muscle has several functions. On the one hand, arm abduction, that is, moving the arm away from the trunk.

On the other hand, he supraspinatus muscle participates in stabilization and flexion of the shoulder joint. Additionally, it works for compression and external rotation of the shoulder.

Injuries that cause pain in the supraspinatus muscle

There are some injuries that can cause pain in the shoulder and supraspinatus muscle. The supraspinatus tendonitis It appears as an inflammation due to friction from repeated shoulder elevation movements.

Another of them is the supraspinatus tendon rupture, caused when sudden abduction movements are made and supraspinatus tendinitis has not been treated in time.

On the other hand, Subacromial syndrome is another injury that causes pain in the supraspinatus.. This presents as intense pain when raising the arm or when extending it to the side.

What is the Jobe test?

An injury to the supraspinatus muscle can cause a lot of pain and disability, even preventing you from functioning normally when carrying out certain daily activities. For this reason, it is necessary to carry out a test for evaluation.

The Jobe test is a maneuver that allows assessing the supraspinatus muscle and its tendon insertion and evaluate if there is a tear or possible compromise of the subacromial space.

 How is the Jobe test performed?

When performing the Jobe test and evaluating the supraspinatus muscle, the following aspects must be taken into account:

  • Position of the patient in the Jobe maneuver. The patient must be sitting or standing. The shoulders will be abducted 90º in complete internal rotation with a horizontal flexion of 30º. The forearms are pronated and the direction of the thumbs will be towards the ground. The patient will have to maintain this position for a few minutes.
  • Shoulder specialist position. Positioned behind the patient, also in a standing position, he will place his hands on the distal third of the forearm, and exert moderate pressure in this area towards the ground.

He Jobe test is considered positive when with the force applied, the patient is not able to keep his shoulders in that position and presents weakness and pain during the maneuver. This indicates that there is a degenerative process of the supraspinatus muscle tendon.

For treatment, the patient is advised to use a shoulder immobilizer for a few days or weeks and, in some cases, to achieve a more effective recovery, sessions with physiotherapy and rehabilitation specialists.

Another treatment for rupture of the supraspinatus tendon when the Jobe test is positive is shoulder arthroresonance. This is a study whose objective is to evaluate the state of the structures that are located within or surrounding the shoulder joint.

This is the type of technique used by specialists in shoulder traumatology, and which, in addition, requires a deeper knowledge of said technique.
