Quadriangular is the deepest muscle of the posterior abdominal wall and is often misidentified as one of the back muscles. It has an irregular shape, but it is normally quadriangular, which is why it is called “quadratus” in Latin.
It binds to the twelfth rib in addition to the spine, making it critical for stabilising both the vertebral column and the rib during various spinal movements. Place your fingers above the posterior iliac crest at the level of your hip to palpate the muscle.
The quadratus lumborum muscle’s anatomy and clinical significance will be discussed in this article.
Origin and placement
The iliac crest and the iliolumbar ligament give rise to the quadratus lumborum. It attaches to the inferior boundary of the 12th rib and the transverse processes of the 1st to 4th lumbar vertebrae, running craniomedially. The muscle appears rectangular when all of the fibres are combined.
Innervation is a term that refers to the process
The subcostal nerve (T12) and the anterior rami of spinal nerves L1-L4 innervate the quadratus lumborum.
Availability of blood
The branches of the lumbar, subcostal, median sacral, and iliolumbar arteries supply blood to the quadratus lumborum.
Purpose
The quadratus lumborum, in essence, aids in the stability and rotation of the spine and pelvis. A bilateral contraction causes the lumbar vertebral column to extend. When only one side of the muscle is stimulated, the trunk bends in that direction (lateral flexion).
Furthermore, the muscle stabilises the 12th rib during thoracic cage movements, assisting expiration (accessory muscle of expiration).
Our blogs, video guides, quizzes, and numbered diagrams will teach you everything you need to know about the deep tissue massage muscles of the abdominal wall.
Deep tissue Massage Therapy - Quadratus Lumborum Release
The QL muscle is located just to the side of the long spinal erectors and is very deep. Because of the many attachments on the ribs, pelvis, and spine, it’s critical to deep tissue massage glides in upward and downward strokes, as well as compress the attachment points directly, to thoroughly cover the muscle.
Post-Isometric Relaxation Technique for the Quadratus Lumborum
The QL is a hip-hiking and side-bending muscle. In the side-lying position, apply light resistance to the top of the hip or pelvis to perform the post isometric relaxation technique.
Theracane Self-Massage - Quadratus Lumborum Release
The Theracane is an excellent self-treatment device for the quadratus lumborum and other back muscles. The curved end of the knob is ideal for hitting trigger points in this location. It’s particularly important to avoid compressing the 12th rib!
What happens to your leg muscles when you get a deep tissue massage?
Deep tissue massage therapy in the musculoskeletal system decreases inflammation and induces mitochondrial biogenesis. Moderate deep tissue massage pressure lowers depression, anxiety, heart rate, and cortisol levels, as well as changing EEG patterns, implying that the body relaxes as a result of the deep tissue massage. This pressure raises the nerve’s average activity while lowering cortisol levels. The effects of moderate-pressure deep tissue massage on different areas of the brain are confirmed by functional data obtained from MRI (magnetic resonance imaging). The amygdala, hypothalamus, and anterior cortex are among the structures involved in stress and sensory regulation. Deep tissue massage can help with a variety of knee issues, including reducing knee pain, rehabilitating sports injuries, reducing stress, calming nerves, lowering anxiety and depression, and improving overall knee health.
What are the advantages of leg deep tissue massage
In medicine, deep tissue massage therapy focuses on the back of the knee, lateral muscles, quadriceps, iliotibial band muscles, and leg muscles to treat leg pain. Deep tissue massage is a one-of-a-kind treatment for plantar fasciitis (plantar fasciitis). Professional athletes, especially those who participate in foot sports such as runners, will benefit greatly from this treatment. This procedure is commonly used by runners to improve their stamina. Illiotibial band syndrome (ITB) and plantar inflammation can also be relieved with deep tissue massage. It’s also used to treat neuromuscular disorders, trigger points, and myofascial release.
Why is it necessary to massage the gastrocnemius muscle with deep tissue massage?
Deep tissue massage can help to relax overworked muscles like the gastrocnemius. Leg muscles may also cause pelvic pain because they influence how we run, walk, and even sit. Flat feet, for example, can cause more pain (especially in women). As the muscles attached to each joint are extended or shortened depending on the angle and location, this force is transferred to the knee and ultimately to the thigh.
Cramps are more common in the following muscle groups
Lower leg and back of leg (gastrocnemius muscle)
In the groyne area (hamstrings)
Ahead of the groyne (quadriceps)
Cramping and stiffness of the legs, arms, and chest muscles are also normal, which aid in the healing process by strengthening the quadriceps and other tissues. Endurance athletes (for example, marathon runners and triathletes) and older people who participate in strenuous physical activity are more likely to experience muscle cramps.
Why is it beneficial to use deep tissue muscle for muscle cramps
Muscle cramps affect almost all at some stage in their lives. While playing tennis, golf, bowling, swimming, or any other sport, muscle spasms may occur. Seizures and lower back strains, on the other hand, may happen while sitting, walking, or even sleeping. Leg cramps are common in some people and may occur as a result of any physical activity. One of the most effective ways to alleviate muscle cramps is by deep tissue massage therapy. Deep tissue massage while stretching the muscle will rapidly alleviate the pain caused by muscle cramps and spasms and release muscle contractions because it increases blood flow to the muscle tissue.
Muscle cramps are more common in infants and small children, people over 65, and all patients, as well as overweight people, those who put a lot of pressure on their bodies during exercise or work, and those who take some drugs or medications.
When athletes’ bodies are not well trained for pre-season workouts and events, they are more susceptible to muscle spasms and get exhausted faster. Seizures always happen in the final minutes of strenuous exercise or 4 to 6 hours later.
What exactly is the quadriceps muscle
The rectus femoris is one of the four muscles that make up the quadriceps muscle. Crushing and contusion of the rectus femoris muscle in front of the thigh is the most common quadriceps injury. This muscle’s most important function is to straighten the knee (lifting the leg). This muscle pushes the leg away from the groyne and positions it around the thigh. Quadriceps weakness reduces knee flexibility. A malfunction of this muscle may also cause knee setback. Deep tissue massage should not be avoided if you want to improve this muscle.
