The erector spinae muscles are a group of muscles the travel the length of your spine. They are responsible for spinal movement and stabilization. These muscles often become overloaded with poor posture of the spine. As a result trigger points often form. These points can cause pain to be felt anywhere along the spine and back. Some of these points can even refer pain into the front abdomen as well
The Abdominal muscles what people think of as your six pack muscles. They are mostly responsible for flexing the spine and postural stability. These muscles are often tight in people with poor posture with a rounded spine. This causes trigger points to developed. Trigger points in the abs cause pain to be felt in the abdomen, but also frequently in the back. Trigger points in the upper abdominals refer pain into the mid back, and points in the lower abdominals produce lower back pain.
The rhomboids are muscles between your shoulder blades that are mainly responsible for pulling your shoulder blades back. Poor sitting posture with the shoulders slumped and rounded forward causes these muscles to become strained and overloaded. When this happens trigger points can form, causing achy pain and restlessness between the shoulder blades.
A common cause of sacral and lower back pain is trigger points in the gluteus medius muscle. This muscle is located in the hip and is responsible for abduction and stabilization of the hip and pelvis. This muscle often harbors trigger points. These knots will often refer pain into the sacrum and lower back area
Low back pain can be a complicated condition. Quite often in my practice I will see multiple muscles involved in causing lower back pain in my clients. For example trigger points in the hip flexors like the psoas muscle, along with trigger points in the back muscles themselves, such as the quadratus lumborum or the multifidus, can all be active and refer pain into the low back. When trigger points are active in multiple muscles at once this is called a chronic myofascial pain syndrome.
The quadratus lumborum muscle or QL. Is a muscle in the lower back. It helps to flex the spine to the side and stabilize the lowback and hip. Trigger points in this muscle are one of the most common causes of low back pain and stiffness. This is probably the most frequent muscle I work on in my practice when treating clients with low back and hip pain.
The gluteus maximus muscle is a major player in hip extension. Despite its involvement in walking, running, skating, and pretty much all types of upright movement it remains largely undeveloped in most bodies. This Lak of strength sets it up for overload injuries like trigger points and myofascial pain. These trigger points not only cause glute and hip pain but are also a common source of sacral pain as well. The best prevention for these problems is strong glutes!!! So stop sitting on your butt, and start strengthening it with resistance training.
The Multifidus muscle is a long muscle that travels the length of the back. It helps move and stabilize the spine. It is a frequent carrier of trigger points. These points can cause back pain anywhere along the back and even into the sacrum. When they are bad enough spillover pain can be referred into the abdomen as well.
