One of the most common causes or low back pain is trigger points in the quadratus lumborum muscle or Q.L. for short. This muscle is located in the lower back and is responsible for trunk and pelvic movement and stabilization. This muscle often harbors trigger points that form from prolonged sitting or bending. Pain from trigger points in this muscle will cause pain in the low back, sacrum, and into the hip.
One of the often overlooked muscles affected by poor rounded shoulder posture is the latissimus dorsi muscle. They are the largest muscles in the back and function primary to adduct the arm and to assist in medially rotating the arm. Chronic strain causes trigger points to build up in the muscle tissue causing pain, referred pain, stiffness and weakness. Trigger points in the lats refer pain into the back, shoulder, and down the arm into the fingers.
One of the most common forms of pain I see in my practice is neck and shoulder pain. Many people have jobs that require the muscles of the neck and upper back to work overtime to keep proper neck posture. Sitting in front of a computer all day or being stuck in a car or truck for example will eventually cause these muscles to become strained and develop trigger points. These trigger points will then cause pain, referred pain, stiffness and weakness. Neck and upper back trigger points will refer pain into the neck and head.
The Abdominal muscles what people think of as your six pack muscles. They are mostly responsible for flexing the spine and postural stability. These muscles are often tight in people with poor posture with a rounded spine. This causes trigger points to developed. Trigger points in the abs cause pain to be felt in the abdomen, but also frequently in the back. Trigger points in the upper abdominals refer pain into the mid back, and points in the lower abdominals produce lower back pain.
The pectoralis minor muscle is a small strip like muscle located underneath the pectoralis major. It functions to protect the shoulder and aid in scapular movement and stabilization. This muscle almost always has trigger points in it due to chronic poor posture where the shoulders are rounded. Federal pain from these trigger points will cause pain to be felt in the chest and down the arm.
The Infraspinatus muscle is part of the rotator cuff. It acts to move and stabilize the shoulder. This muscle is often chronically strained in people who have a rounded shoulder posture. With this type of strain trigger points can develop. These knots in the muscle will cause pain to be felt in the front of the shoulder and down the arm.
The supraspinatus muscle is one of your rotator cuff muscles in the shoulder. It helps to move and stabilize the shoulder joint. Poor posture can cause this muscle to become strained and irritated. Rounded shoulders can cause strain in this muscle and can even cause the tendon of this muscle to become impinged with overhead shoulder movement. Trigger points that form in this muscle will cause pain to be felt in the shoulder, elbow, and down the arm.
The pectoralis major is the main chest muscle. In mainly functions to adduct the arm, and medially rotate the arm. This muscle is always right with a rounded shoulder posture. When trigger points form in this muscle they produce pain felt in the chest and down the arm.
The sternocleidomastoid muscle is a thin strap like muscle located on both sides of the front of the neck. It helps with movement and posture of the head and neck. This muscle often becomes shortened and tight in people with poor head forward posture. As a result trigger points can form, and these points can cause pain to refer into the skull, and face around the eye. Trigger points in this muscle can also refer into the inner ear.
