The supraspinatus muscle makes up part of the rotator cuff. It is responsible for assisting in shoulder abduction as well lateral rotation and stabilizing the shoulder joint. This muscle is often overloaded in labourers and tradesman who have to do a lot of overhead work. Athletes who do a lot of throwing movements will also frequently have Tigger point in this muscle. These trigger points will cause pain to be felt into the shoulder and down the arm, as well as stiffness and weakness.
People often think of a massage as a relaxing experience, something they might do occasionally, or give as a gift along with a trip to the spa. Trigger point massage therapy is another kind of massage used to treat pain and physical dysfunction. Trigger points can develop in people from all walks of life. They can affect people of all ages, office workers and labourers, elite and weekend athletes, post surgical patients, people with acute pain from injury and people with chronic pain. Trigger point massage therapy can treat a wide variety of physical conditions such as:
– back pain.
– Carple tunnel syndrome
– achy persistent pain
– pain from Fibromyalgia
– post surgical pain and scarring
– soft tissue injuries related to sports
– TMJ dysfunction
The infraspinatus muscle is one of the muscles that makes up the rotator cuff. It functions to laterally rotate the shoulder and to stabilize the shoulder joint. Rotator cuff problems are common and can be caused by both acute injuries, or chronic repeditive movements, and poor posture. When this happens trigger points will form causing pain, refered pain, as well as stiffness and weakness. Refered pain from trigger points in the infraspinatus can be felt into the front of the shoulder and down the arm. Trigger points can also produce a sensation the the shoulder joint isn’t “sitting right”. Trigger points must be released to relieve these symptoms.
TP’s were first brought to the attention of the medical world by Dr. Janet G. Travell. Dr. Travell, physician to President John F. Kennedy, is the acknowledged Mother of Myofascial Trigger Points. In fact, “Trigger Point massage, the most effective modality used by massage therapists for the relief of pain, is based almost entirely on Dr. Travell’s insights.”2 Dr. Travell’s partner in her research was Dr. David G. Simons, a research scientist and aerospace physician.
Trigger Points are very common. In fact, Travell and Simons state that TP’s are responsible for, or associated with, 75% of pain complaints or conditions.1 With this kind of prevalence, it’s no wonder that TP’s are often referred to as the “scourge of mankind”.
Trigger Points can produce a wide variety of pain complaints. Some of the most common are migraine headaches, back pain, and pain and tingling into the extremities. They are usually responsible for most cases of achy deep pain that is hard to localize.
A TP will refer pain in a predictable pattern, based on its location in a given muscle. Also, since these spots are bundles of contracted muscle fibres, they can cause stiffness and a decreased range of motion. Chronic conditions with many TP’s can also cause general fatigue and malaise, as well as muscle weakness.
The Gluteus medius is located in your hip. It is important for hip stability, and functions to abduct the hip. When trigger points form in this muscle pain can be felt deep into the sacrum and the hip, as well as down the lateral thigh. Trigger points in this muscle are an often overlooked source of low back and sacral pain.
