How the Heart Works Elara Systems
We'll start with the basics and examine how the human heart works. The heart is a muscle about the size of a clenched fist that is located under the rib cage and between the lungs. It is divided into a left side and a right side. Each side has two chambers. The upper chambers are called atria and the lower chambers are called ventricles. Blood flows from the atria to the ventricles through one way valves. The atria and the ventricles work together as a team to pump blood through the heart.
The right atrium receives oxygen depleted blood from the body and pushes it into the right ventricle, which pumps it out to the lungs. Oxygen enriched blood is returned from the lungs to the left atrium which pushes it into the left ventricle, where it is pumped back out to the body. After the body has used all the oxygen in the blood, the blood returns to the heart and the cycle repeats. In a normal heart this sequence occurs sixty to one hundred times per minute. The heart's beating rhythms are driven by electrical impulses within the heart.
Myofascial Pain Syndrome and Trigger Points Treatments, Animation.
Myofascial pain syndrome is a common chronic pain disorder that can affect various parts of the body. Myofascial pain syndrome is characterized by presence of hyperirritable spots located in skeletal muscle called trigger points. A trigger point can be felt as a band or a nodule of muscle with harder than normal consistency. Palpation of trigger points may elicit pain in a different area of the body. This is called referred pain. Referred pain makes diagnosis difficult as the pain mimics symptoms of more wellknown common conditions. For example, trigger point related pain in the head and neck region may manifest as tension headache,.
Temporomandibular joint pain, eye pain, or tinnitus. Symptoms of myofascial pain syndrome include regional, persistent pain, commonly associated with limited range of motion of the affected muscle. The pain is most frequently found in the head, neck, shoulders, extremities, and lower back. Trigger points are developed as a result of muscle injury. This can be acute trauma caused by sport injury, accident, or chronic muscle overuse brought by repetitive occupational activities, emotional stress or poor posture. A trigger point is composed of many contraction knots where individual muscle fibers contract and cannot relax. These fibers make the muscle.
Shorter and constitute a taut band a group of tense muscle fibers extending from the trigger point to muscle attachment. The sustained contraction of muscle sarcomeres compresses local blood supply, resulting in energy shortage of the area. This metabolic crisis activates pain receptors, generating a regional pain pattern that follows a specific nerve passage. The pain patterns are therefore consistent and are well documented for various muscles. Treatment of myofascial pain syndrome aims to release trigger points and return the affected muscle to original length and strength. Common treatment options include.
Manual therapy, such as massage, involves application of certain amount of pressure to release trigger points. The outcome of manual therapy strongly depends on the skill level of the therapist. The Spray and Stretch technique makes use of a vapor coolant to quickly decrease skin temperature while passively stretching the target muscle. A sudden drop in skin temperature provides a pain relief effect, allowing the muscle to fully stretch, and thus releasing the trigger points. Trigger point injections with saline, local anesthetics or steroids are well accepted as effective treatments for myofascial trigger points.
