The shoulder muscle functionality allows support and stability to the flexible joints in the body. The shoulders allow a full range of motion without feeling pain or discomfort, like throwing a ball or reaching an item on the shelf. The shoulders are also supported by many muscles, tendons, and ligaments surrounding the rotator cuffs that allow the shoulders to remain stable. The rotator cuffs consist of four muscle groups that allow the arms to be mobile. However, the range of motion from the shoulders and the rotator cuff can be prone to injuries and become unstable. To that point, the shoulders and their associated muscles are often the sites for many issues to develop. Today’s article looks at the supraspinatus muscles in the rotator cuffs, how trigger points affect the rotator cuffs and various therapies for rotator cuff injuries. We refer patients to certified providers who specialize in musculoskeletal treatments to aid individuals suffering from trigger points related to the shoulders affecting the rotator cuffs and the supraspinatus muscles. We also guide our patients by referring them to our associated medical providers based on their examination when appropriate. We ensure to find that education is the solution to asking our providers insightful questions. Dr. Jimenez DC observes this information as an educational service only. Disclaimer
The Supraspinatus Muscles In The Rotator Cuffs
Do you feel stiffness along your shoulders? Does it hurt when you rotate them? Or have you been experiencing numbness and tenderness traveling your upper arm? Individuals experiencing these symptoms in their shoulders could be dealing with trigger points along the supraspinatus muscles. The supraspinatus muscle resides in the supraspinous fossa of the scapular spine and is superiorly located in the rotator cuff muscles. The supraspinatus muscle is associated with the other muscles that surround and support the rotator cuffs in the shoulder, which include:
- Teres Minor
These four muscles closely relate to the deltoid muscles to provide stability, movement, and rotation to the upper arm joint. When issues affect the shoulders or the rotator cuffs, it can cause the rotator cuff muscles to develop trigger points and other associated symptoms along the upper arm.
How Trigger Points Affect The Rotator Cuffs
When the muscles of the rotator cuffs become injured, many issues may cause musculoskeletal complaints. Studies reveal that tendinopathy or tendon injuries are often characterized by pain in and around the tendons in the rotator cuffs and are associated with repetitive actions. When the supraspinatus muscle becomes overused due to repetitive motions, it can develop trigger points to affect the rotator cuffs. Studies reveal that local and referred pain symptoms reproduce active trigger points in the muscles surrounding the shoulders and rotator cuff that many individuals recognize as familiar pain. According to Dr. Janet G. Travell, M.D., the activation of trigger points associated with the supraspinatus muscles are activated from strenuous activities like carrying heavy objects, walking a large dog that is pulling the leash, or lifting an object above shoulder height with the arms outstretched. These strenuous activities allow the trigger points to form along the supraspinatus muscles and cause referred pain symptoms on the shoulders.
Stretching The Supraspinatus Muscles- Video
Have you been feeling stiffness along your shoulders? Do you feel tenderness in certain areas of your shoulders or arms? Or do you experience a numbing sensation running down your arms? If you have been experiencing these issues along your shoulders and upper arms, it could be due to trigger points associated with the supraspinatus muscles. Trigger points are small knots along the taut muscle band of any muscle group that can mimic any overlapping condition that can cause issues to the body. For example, shoulder pain is associated with trigger points along the supraspinatus muscle. The video above shows how to stretch the supraspinatus muscles to reduce future trigger points from forming along the rotator cuff muscles. Individuals who incorporate stretching exercises for shoulder pain associated with the supraspinatus can feel relief in their shoulders as the overall function is restored and the pain is reduced.
Various Therapies For Trigger Points Associated With The Rotator Cuffs
The various therapies for trigger points associated with the rotator cuffs can help reduce the pain-like symptoms along the supraspinatus muscles. Studies reveal that exercises and manual therapy can help decrease pain along the supraspinatus muscles and increase shoulder muscle strength and function. Other treatments like chiropractic care can benefit many patients with shoulder pain or injuries that can help reduce pain, improve ROM (range of motion), increase flexibility, and even restore function to the joint. Depending on how severe the muscle injury is on the shoulders, chiropractors utilize various techniques to assess the pain and help address all the areas of the body to relieve the issue without using drugs.
The supraspinatus muscles are part of the rotator cuff muscle group and work alongside the shoulder muscles to provide mobility and a full range of motion to the upper arm without feeling pain. When strenuous activities or injuries occur to the shoulders or the rotator cuffs, it can cause myofascial pain syndrome or trigger points to develop along the overused muscles in the shoulders and cause pain-associated symptoms. This can affect the mobility of the shoulders and arms from going through a full range of motion. Various therapies are available to help reduce pain, restore functionality to the shoulders and surrounding muscles associated with trigger points, and can help improve motor function. Treatments for shoulder pain associated with trigger points can help prevent future issues from forming and improve shoulder functionality.
