The lateral pterygoid muscle is involved in movement of the jaw. It can become become strained from chronic clenching of the jaw and grinding of the teeth. When this happened trigger points can form. This leads not only to pain and refered pain, but also dysfunctional joint mechanics. This muscle is a major player in TMJ dysfunction syndrome.
The medial pteragoyd muscle is located on the inside of the jaw. It is responsible for jaw movements during talking and chewing. This muscle becomes over loaded from poor neck posture as well as stress resulting in grinding the teeth or excessive clenching of the jaw. Trigger points in this muscle will refer deep into the jaw and the tempomandibular joint producing “tmj dysfunction syndrome.
The multifidus muscle is a long muscle that travels the length of the spine. It has different actions on different parts of the spine. It extends and laterally flexes the cervical and lumbar spine, and rotates the thoracic spine. Trigger points in this muscle are common due to poor posture and bad movement mechanics. Trigger points in the lumbar area area are a common cause of low back pain. These lower points can also refer into the abdomen. Points that form in the cervical region will refer pain down the neck into the shoulder blade area.
The rectus femoris muscle is one of your quad muscles. It acts primarily to extend the knee but it also helps to flex the hip. This muscle is often overloaded from athletic activity, but it also can become chronically shortened from prolonged sitting. Trigger points will refer pain deep into the knee producing a deep ache felt into the joint.
the serratus anterior muscle is located on the side of the trunk. It attaches onto the ribs and the scapulae. This muscle assists in scapular motion and stability as well as assisting the movement of the ribs. Trigger points can form in this muscle due to poor shoulder posture. Once formed, these points will cause pain to be felt in the side, under the armpit, and down the inside of the arm. Once formed trigger points will not release on their own, they require a manual technique such as trigger point massage.
The sternocleidomastoid muscles are two strap like muscles located in the front of the neck. They are responsible for producing head movements like flexion, as well as rotating the head to the opposite side. These muscles often become chronically shortened due to poor posture such as sitting in front of a computer screen for to long. When this happens trigger points can form. These points will refer pain into the head, face, and skull producing headaches. Trigger points won’t resolve by themselves, a manual intervention like trigger point massage is required to cause a release.
the rhomboids are muscles located in your upper back. They lie underneath the trapezius muscle. These muscles are responsible for retracting your scapula, or pulling your shoulder blades back. Since poor posture causes the shoulders to round forward, the rhomboids are often strained. When this happens trigger points will form. These points cause deep achy pain to be felt along the shoulder blade. Once trigger points have formed they will not release on there own. A manual release such as trigger point massage is required.
