Introduction

The shoulders help stabilize the upper extremities of the body and provide a wide range of movements for the arms. The shoulders have many muscles, ligaments, and tendons that help support the joints from injuries and utilize the motor function to do everyday actions like throwing a ball or stretching for long distances. Even though the shoulders help stabilize the upper extremities, they are still prone to injuries since the shoulder muscles are constantly used throughout the day. One of the shoulder muscles that are continuously utilized is the deltoid muscle, which can lead to the development of trigger points when it becomes injured. Today’s article examines the deltoid muscles, how trigger points affect the deltoids and shoulders, and managing trigger points associated with the deltoid muscles. We refer patients to certified providers specializing in shoulder pain treatments to aid individuals suffering from trigger points associated with the deltoid muscles along the shoulders. We also guide and inform our patients by referring them to our associated medical providers based on their examination when appropriate. We ensure that education is a great solution to asking our providers insightful questions the patient requests. Dr. Jimenez DC observes this information as an educational service only. Disclaimer

What Is The Deltoid Muscle?

 

Have you been feeling pain on the top of your shoulders? Do your shoulders feel stiff when rotating them? Or do you feel radiating pain along your upper arms? Individuals with shoulder pain may be experiencing trigger points affecting their deltoid muscles. The deltoids are large triangular-shaped muscles that are associated with the shoulder girdle. The deltoids sit on top of the shoulder girdle and have anterior and posterior sections that work together with the rotator cuff muscles that provide a full range of motion to the arms. Studies reveal that the deltoid muscles have a more complex structure since the intramuscular tendons from the deltoids help provide different functions when it comes to the shoulders and arms’ motor function. According to Dr. Janet G. Travell, M.D., the anterior sections of the deltoid muscles are used in sports activities. In contrast, the posterior section works with the rotator cuff muscles for mobility. Injuring the deltoid muscles can lead to the development of trigger points associated with shoulder pain. 

 

How Do Trigger Points Affect The Deltoids & Shoulders?

 

Regarding the shoulders, they can succumb to various injuries that can become an issue over time, lead to the development of trigger points in the shoulder muscles, and cause referred pain to the upper arms. Trigger points or myofascial pain syndrome along the deltoid muscles may invoke referred pain to the shoulders. Studies reveal that myofascial pain syndrome is often described as the sensory, motor, and autonomic symptoms caused by trigger points that cause tender spots on the hardened muscle to produce pain. Trigger points are a bit tricky to diagnose since they mimic other chronic conditions in the body. The deltoid muscles are superficial, and trigger points can cause referred pain to the muscles that mimic arthritis in the shoulder joints. Some of the other symptoms associated with trigger points along the shoulders and deltoids include:

• Limited range of mobility
• Tenderness in the shoulder muscles
• Muscle spasms
• Muscle pain
• Stiffness in the deltoid muscles

Pain in the shoulders can cause the body to become unstable and cause many individuals to develop a hunched position over time to reduce the pain they are feeling; fortunately, there are various ways to manage the pain associated with trigger points along the shoulders and deltoid muscles.

Trigger Point Release On The Deltoid Muscle- Video

Have you been feeling stiffness along the shoulders or the deltoid muscles? Have you experienced muscle tenderness in your upper arms? Or do you feel like being hunched over reduces the pain in your shoulders? If you have been experiencing any of these symptoms, it could be the development of trigger points associated with shoulder pain along the deltoid muscles. Trigger points cause referred pain to the affected muscle area and are developed when the muscles are overused. For the deltoid muscles, when active trigger points affect the deltoids’ anterior or posterior sections, it can cause the muscles to twitch and later cause moderate tension. The video above explains where the trigger points are located on the deltoid muscles and how to release them through palpations and massages. This is one of the techniques that can help manage trigger points from affecting the shoulders and deltoid muscles.

Managing Trigger Points Associated With The Deltoid Muscles

 

When dealing with trigger points associated with the deltoid muscles can be managed through various techniques that many people can utilize to reduce the pain symptoms along the upper arms and shoulders. Studies reveal that dry needling is one of the techniques that can relieve trigger points to ease the pain intensity and irritability to the shoulders. Other techniques that many people can utilize are to correct how they carry heavy objects to reduce the load on their shoulders, stretch the arms and shoulders to minimize soreness and alleviate tight muscles, and even take a hot shower to relax the shoulder muscles, can reduce the chances of trigger points from forming in the future. 

 

Conclusion

The deltoid is located on top of the shoulder girdle and is a large triangular-shaped muscle that works together with the rest of the shoulder and the rotator cuff muscles. The shoulders have many muscles, ligaments, and tendons that provide stability and perform everyday functionality to the body. When the shoulders become injured, the affected muscles could potentially develop trigger points to cause referred pain to the shoulders and upper arms. When trigger points affect the deltoid muscles, it can cause them to have symptoms of stiffness, tenderness, and pain that mimic other chronic conditions affecting the shoulders and arms. Thankfully, various techniques relieve referred pain from the arms and help manage trigger points along the deltoid muscle. This allows the deltoid muscle to relax and reduce trigger points from developing further on the shoulders.
