Myofascial Trigger Points
The word myofascial means muscle tissue – myo and the connective tissue in and around it – fascia. Trigger points are an extremely common cause of pain. They are hyperirritable spots and are often referred to as ‘knots’ that range in a size from a tiny pin head to a small pea.
They are usually located in places where nerves are connected to the muscle fibres. These points are associated within a taut band of skeletal muscle that inhibits full lengthening of the muscle and creates a muscle weakness or muscle contraction. TPs are painful when pressure is applied and often with a referred pain that’s felt distantly, on another area of the body.
Myofascial pain often results from muscle injury or repetitive strain. The trigger point formation can be attributed to either muscle overload, an injury, a lack of exercise, poor posture, birth trauma, nutritional deficiencies or structural imbalances.
While treating the trigger point is beneficial, it’s also very important to find the cause of its formation. Long term success depends on understanding what causes trigger points to develop and to prevent their development and recurrence.
