Myofascial trigger points
Trigger points are areas (points) of severe irritation within a muscle fascia. On palpation, this area is painful and triggers the typical referred pain. In some cases, this may also trigger autonomic reactions.
A distinction is made between active and inactive trigger points. Active trigger points cause pain both at rest and when the relevant muscle fascia is under strain. Inactive trigger points, on the other hand, only cause pain upon palpation.
The following factors can contribute to the development of trigger points:
• Muscle strain
• Trauma
• Hypothermia
• Activation by other trigger points
• Disorders of internal organs
• Inflammation
• Stress
• Autonomic nervous system overload
The areas surrounding trigger points also exhibit what is known as ‘metabolic derailment’. The tissue has increased energy requirements whilst simultaneously suffering from a lack of oxygen. This condition can be exacerbated by reduced blood circulation.
Based on these observations, it is hypothesised that microcurrent therapy – and, in particular, LED light therapy using blue and green light – improves the metabolic situation at trigger points, thereby leading to a reduction in the sensation of pain on palpation. (Richter & Hebgen, 2007, p. 115)
Muscular trigger points are small, painful knots that can form in the muscles and tissues of the body. They can be caused by a range of factors, including overuse, strain injuries, poor posture and stress. If left untreated, they can lead to long-term pain and functional impairment.
Trigger points may be felt as areas of hardening or knots in the muscle tissue and can cause pain when pressed. This pain may also radiate to other parts of the body, which can lead to a chain reaction of symptoms.
A common method for treating muscular trigger points is trigger point therapy. This method involves the targeted pressing and stretching of the affected muscles to release the knots and reduce pain. It may also involve the use of heat or cold, massage or electrostimulation.
It is important to note that a combined approach is often necessary when treating muscular trigger points. This may include a combination of trigger point therapy, exercise and stretching, as well as changes to diet and lifestyle.
A qualified therapist or doctor can help identify the cause of your muscular trigger points and develop a personalised treatment plan. This can help you relieve pain, improve your body’s function and help you prevent future trigger points.
In summary, muscular trigger points are small, painful knots in the muscles and tissues that can cause pain. They can be caused by overuse, strain injuries, poor posture and stress, and can be treated through trigger point therapy, exercise, stretching and changes to diet and lifestyle.
