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.
trigger points are well known for causing pain, but did you know that trigger points can also cause muscle weakness as well? The muscle fibers that are locked together in a trigger point cannot be used to produce muscular contractions thus weakening the entire muscle.
Trigger points are hyper irritable knots found in muscle tissue. These points form in a muscle due to overload stress. Trigger points can form anywhere, in any muscle. Once formed they irritate sensory nerves and produce pain, refered pain, weakness, and stiffness. Trigger points will also mimic symptoms of other conditions such as “sciatica” or Carple tunnel syndrome. Trigger points will not go away on there own, they must be manually released with hands on techniques like trigger point massage.
The serratus anterior muscle is responsible for scapular and rib movement and stability. This muscle can become overloaded from poor posture of the shoulders, as well as heavy breathing from exertion. Trigger points in this muscle will cause pain to be felt under the armpit into the shoulder blade area, and down the arm into the fingers.
Myofascial trigger points form in a muscle due to overload stress. A portion of muscle fibers lock up into a knot. Once formed these points will irritate sensory nerves that are in proximity to the knot. When this happens,
trigger points have the capacity to refer pain along specific distributions or patterns that are well mapped out. sometimes pain may be felt at a great distance away from the actual point itself.
the glute medius is a major pelvic stablizer. It is often overworked in runners and hockey players. trigger points in this muscle will cause pain to be felt in the hip and down the back of the leg.
