Why do we need rotator cuff muscles?

According to Athwal (2017), the rotator cuff is a set of four muscles that form a "cuff" over the head of the humerus via tendons. The scapula leads to the four muscles that make up the following muscles:

The larger and lesser tuberosities are where the rotator cuff tendons join to the humeral head. These muscles altogether allow the rotator cuff to perform its important role of arm lifting and rotation as well as the stabilization of the shoulder's ball within the joint (Maruvada et al., 2021)

What is a Muscle Energy Technique (MET)?

Muscle Energy Technique (MET) is a type of soft tissue manipulation used to treat muscle imbalances and other issues. This was developed by Fred Mitchell, Sr. and Fred Mitchell, Jr. In MET, small contractions are used to stretch a tight muscle while they’re in their shortened state. The purpose of MET is to gain control over trigger points and improve mobility in muscles with limited range of motion. MET is an active approach in which the patient acts as in active participation, as opposed to static stretching, which is a passive technique in which the therapist does all of the work.

MET can be beneficial for improving stability in both shoulders. Athletes who perform overhead movements, like baseball pitchers or swimmers, tend to experience shoulder pain due to injuries like rotator cuff tears or labral problems. While steroids injections can help reduce shoulder pain and inflammation caused by these conditions. They only treat symptoms—not underlying causes of shoulder pain. In addition, it may have negative side effects if not administered correctly by professionals.

When should you use muscle energy technique (MET)?

Muscle Energy Techniques can be utilized for any issue where the goal is to relax and lengthen muscles while also improving joint range of motion (ROM). Almost any joint in the body can be safely treated with METs. A lot of athletes employ MET as a prophylactic treatment to avoid muscle and joint injury in the future. It is mostly utilized by those who have limited range of motion in their neck and back owing to facet joint dysfunction. Likewise, for larger issues including shoulder discomfort, scoliosis, sciatica, asymmetrical legs, hips, arms. It could also treat persistent muscular pain, stiffness, or injury.

How do you perform Muscle Energy Technique (MET)?

Muscle energy technique is effective for shoulder pain relief and it's easy to learn which is why its use in recent years have increased. Here's how you can do it for your patients. 

Physical Examination (Muscle Energy Technique Shoulder)

You will have to look at the natural range or passive range of movement of the patient. Have your client lie supine and you move their arm into abduction to a 90° angle.

External rotation of the shoulder, natural range or passive range of motion ROM should be between 80 and 90° degrees-Chapsman Reflexes Blog Image

Bend the elbow and passively check for external rotation of the shoulder as seen in the photo below. You are assessing their current ROM or the limits to their range of motion, normal range should be between 80 and 90°. If the range of external rotation is less than these numbers it can indicate that either the pectoralis major, the latissimus dorsi, and/or the teres major may be inhibited and shortened, which decreases this range performed within the upper extremity.

Next, check the internal range of the arm. Move the arm passively into internal rotation. The normal range is 70° to 90° with any limitations perhaps coming from dysfunctions in either or both the subscapularis or teres minor muscles. We also note for any ‘hard end feel’ which may indicate bony issues which means we would do further joint assessments.

Performing Muscle Energy Treatment (MET) Shoulder

Move their forearm into an external rotation to perform MET. It is important that you stop at the first point where you feel restriction of the tissues. This is called Point of Bind and is at this length of the tissues that we get optimum results. They contract back towards internal rotation at 40% of the effort and no more; it is an isometric contraction where you are stabilizing the wrist and elbow to keep the joints motionless. This contraction is held for approximately 7 to 10 seconds. Ask your patient to take a deep cleansing breath and as they exhale they stop applying pressure of the muscle contraction. Keep in mind that it's important that their arm doesn't move. You will still be holding the wrist and elbow through the entire procedure and finding a new point of bind after each of the post-contraction relaxation phases.

Post-contraction Relaxation Phase

This time called Post-contraction Relaxation is when the tissues that had been contracting relax even further. We stay in limb ‘stiffness’ for up to 90 seconds and in this time the muscles relax even further so that we find the new passive end range or apply our new point of bind. Ask the patient to apply the contraction into internal rotation, still at 30% to 40% of their effort. This contraction again should be a minimum of 7 - 10 seconds. We get them to take cleansing breaths on each exhalation to improve the parasympathetic effect on the tissues; they can relax their muscle contraction as they breathe out.

Important Notes

Do the technique 3 times to see the most effective changes. Tell them to take a deep cleansing breath and that they relax the muscle contractions as they exhale. We reassess the ROM of external rotation after the third contraction and relaxation phase and we should see greater evidence of improved length through that range of motion.

This is a gentle technique for patients that feel pain and/or for those with issues in their range of motion. You might not want to use this treatment when there's a bony block when you test out the ranges. Be aware that if there's a joint restriction, we'd apply a mobilization technique or we'll adjust something deeper into that joint capsule.

Myotherapy: Glenohumeral Joint Pain Treatment

Patients can come in with pain and stiffness from the neck that can refer to and causes elbow wrist and shoulder pain- acromioclavicular (AC) joint and the glenohumeral (GH) joint. Typically, it impedes movements such as lifting of the arms, brushing the teeth, or holding a golf club. It may be described as a moderate pain or a chronic pain that could affect sleep especially if it’s the shoulder you sleep on.

Shoulder Anatomy

You can help them by applying a variety of techniques to relieve uncomfortable pain or sensations in and around that area. But first, let's understand the shoulder anatomy. Since it is one of the most unstable joints in the body with the most movement, it can be complex to understand its structure and functionality.

Shoulder Structure and the three kind of bones, glenohumeral joint- Chapmans Reflexes Blog Image

The two shoulder joints that are prone to injury are the acromioclavicular (AC) joint and the glenohumeral (GH) joint. 

  • The acromioclavicular joint is situated where the clavicle is in contact with the acromion and the scapula. 
  • The glenohumeral joint is where the socket of the scapula connects with the rounded head of the humerus. It is responsible for the wide range of motion of the shoulder including flexion, extension, internal and external rotation, adduction and abduction and circumduction. 

There are  eight muscles attached to the bones of the shoulder. They are responsible for the form we see of the shoulder and underarm, they aid in its range of movement, and help protect the GH joint which is the main primary joint involved in function.

The deltoid muscle, which you may also know as the deltoideus muscle, is the shoulder muscle considered to be the largest and responsible for stabilization of the shoulder joint for the prevention of dislocations. 

The other muscles which work with the deltoid for shoulder movement and its functions include:

  • Infraspinatus - for arm raise and lowering
  • Triceps brachii - arm straightening
  • Pectoralis major - connects to the sternum
  • Pectoralis minor - stabilizes the scapula
  • Teres major - arm rotation 
  • Biceps brachii - rotates the forearm; flexes the elbow
  • Latissimus dorsi - helps with arm rotation and movement away from and close to the body
  • Subscapularis - aids to rotate the humerus 
  • Supraspinatus - help to raise arm away from the body

Shoulder Pains and Problems

Muscle Energy Technique

When any of the aforementioned muscles become dysfunctional, inhibited and reduced in their passive resting length, they tend to pull the humerus forward. According to OrthoInfo, shoulder problems that patients can experience fall into these categories:

  • Tendon inflammation - can be bursitis or tendinitis
  • Shoulder Instability - stretched lining of the shoulder joint, labrum, or ligaments 
  • Arthritis - joint tenderness and swelling
  • Fracture - can be caused by trauma or injury from a fall, sports activities, vehicular accident, or a direct hit to the shoulder

Other causes for shoulder pain that are less common include infections, tumors, and nerve related problems.

In this article, we are going to focus on glenohumeral joint pain and an amazing muscle energy technique that could improve the humerus’s resting position. This will improve the quality and range of motion and reduce the notable pain felt by your patient. 

Almost any joint in the body can be safely treated with these techniques. Many sportsmen utilize them to avoid future muscle and joint injuries. It's primarily used by people who have restricted range of motion in their neck and back due to facet joint dysfunction found in the neck and back, for those who have broader issues like shoulder pain, sciatica, scoliosis, unsymmetrical legs, hips, or arms, and to treat chronic muscle pain, stiffness, or injury.

Conducting the Assessment

You can clearly see how  far forward the humerus of the patient is. To conduct the test, ask them to be seated comfortably. Stand behind the patient and place your hand over their shoulder. Press your thumb into the tissue, as is in the picture below, until you can palpate the humerus. Note how far forward the humerus is, you can apply a second finger along with your thumb for a more clearer view.

Conducting the assessment for shoulder pain, glenohumeral joint and problems-Chapmans Reflexes Blog Image

Upon confirming that the humerus is anteriorized and checking if any symptoms of pain locally, and/or radiating up in the neck down to the elbow and wrists are present, you can go ahead with this simple muscle energy technique that will improve length of restricted tissue and bring the humerus back into the glenohumeral joint.

Treatment

Let’s begin with the treatment steps. Here’s what you can do:

  1. Have your patient lie on their back (supine).
  2. Put your four fingers behind the humerus while your thumb and wrist sits on top of the humerus.
  3. Slide your thumb down until you get into a firm position.
  4. Push the top end of the humerus down, letting it press onto the table. At the same time, let your other hand elevate the elbow. Continue to do this seesaw-like motion that gently moves the humerus in the capsule a couple of times. Since it can be quite tender, remember not to apply too much force. 
  5. Apply gentle pressure until you can feel the bony end range and ask the patient to push their elbow to the floor and hold it for about 10 seconds. 
  6. Let the patient take a deep breath and when they release their breath you reduce the pressure applied to the limb whilst ensuring that the joint remains in an isometric position. 
  7. Repeat steps four to seven: You apply a rhythmic rocking back and forth motion of the humerus within the joint space for approximately 30 - 45 seconds or until it has a softer feel on the movement, it will start to have a smoother end feel. Continue with the gentle push while the patient takes a deep breath. When they breathe out, stop applying pressure as a counterforce on their humerus. When you apply the muscle energy technique, here are several tips to remember. When pushing down gently, hold it for about 10 seconds and ask the patient to exert 30% to 40% of their effort. Let them take a deep cleansing breath in and when they breathe out, that's when they stop contracting. You can do this three times before reassessing the joint position again. This should make headway into better movement patterns and reduced myofascial pain of the shoulder and surrounding compromised structures.
