These are typically weakened or lengthened muscles that may cause postural distortion or chronic pain. Keep in mind the right side is a view of the muscles deeper than the muscles shown on the left. These muscles must be strengthened for optimal function to occur.
Here are common pain locations from the weakened upper back muscles and overtight anterior muscles. These pain points are likely trigger points and need to be released before the strengthening exercises.
Posterior muscles that often have trigger points that are not felt until pressure is applied.
Overactive muscles of the core. The right side is the deeper muscle layer. Chronic tension of the piriformis often causes sciatica symptoms. It is important to mention if you have ever had or have a burning or tingling sensation down your leg and possibly into your foot. The piriformis will need to be addressed.
90% of the clients I work on with chronic upper back pain have trigger points or pain in these locations. And they never knew they had that pain or tension until I pressed directly on the muscle. Stretching these muscles and foam rolling will help relieve a lot of the pain and tension.
The quadratus lumborum (QL) and Psoas play a major part in chronic low back pain and tension. People who experience pain in the low back almost never assume it’s coming from either of these muscles. Both these muscles have attachments on the lumbar spine and when they become tight, they can cause trigger points to form affecting different areas of the hip, low back, and even legs. The psoas is especially tight in those whom sit prolonged hours at a time without stretching. The QL also may become tight due to prolonged sitting.
Overactive muscles of the anterior (front) and medial (inside) leg and thigh.
