Trigger points are areas of tenderness in a muscle. There are two basic types of trigger points: active and latent.
Active trigger points cause muscular pain and will refer pain and tenderness to another area of the body when pressure is applied. Latent trigger points only exhibit pain when compressed, they do not refer pain to other areas of the body. Latent trigger points are believed to be one of the causes of stiff joints and restricted range of motion of old age.
Trigger points may be associated with myofascial pain syndromes or fibromyalgia. Trigger points are very common. They are also referred to as muscle knots.
Trigger points differ from acupressure points. Acupressure points are concentrations of energy or blockages of the body’s energy pathways. Trigger points are physical phenomena that can be felt by touch.
The pain caused by trigger points may be the biggest cause of disability and loss of time in the workplace.
