What You'll Learn
The multifidus muscle is located in the deep muscles of the back
The multifidus muscle is a group of short, triangular muscles that are part of the transversospinales or transversospinal muscle group. It is located in the deep muscles of the back, specifically in the third or deep layer. The multifidus muscle spans the whole length of the vertebral column, from the cervical to the lumbar spine, but is most developed in the lumbar area.
The multifidus muscle is found on either side of the vertebral column and fills the groove on either side of the spinous processes of the vertebrae. It is located deep relative to the spinal erectors, transverse abdominis, abdominal internal oblique muscle, and abdominal external oblique muscle. The multifidus lies deep to the semispinalis and superficial to the rotatores.
The multifidus muscle plays an important role in spinal stability and movement. It helps to control the movement of individual vertebrae, preventing excessive motion, and maintaining proper alignment. The multifidus muscle also aids in several movements of the vertebral column. When contracting bilaterally, the multifidus extends the spine, while unilateral contraction aids in lateral flexion of the spine to the same side and rotation of the spine to the opposite side.
The health of the multifidus muscle is important for maintaining a healthy spine and preventing back pain. Weakness or dysfunction in the multifidus muscle can lead to low back pain and core issues. This can be caused by a lack of physical activity, prolonged sitting, poor posture, or injuries to the lumbar region. Strengthening the multifidus muscle through exercises, stretching, and manual treatments can help maintain spinal health and reduce back pain.

It is part of the transversospinales muscle group
The multifidus muscle is a long, narrow muscle that runs on either side of the spinal column. It is one of the transversospinalis muscles, which is a deep group of back muscles that lie deep to the erector spinae. The transversospinalis muscle group consists of three major subgroups: the semispinalis, multifidus, and rotatores muscles. These muscles lie between the spinous and transverse processes of the vertebral column and are responsible for spinal stability, proprioception, and posture.
The multifidus muscle is composed of many short, triangular muscles that span the entire length of the vertebral column but are thickest and most developed in the lumbar region. It is located just superficially to the spine itself and works to stabilize the joints at each level. The stiffness and stability provided by the multifidus muscle make each vertebra work more effectively and reduce the degeneration of joint structures caused by friction from normal physical activity.
The semispinalis is the most superficial muscle in the transversospinalis group, spanning the thoracic and cervical regions of the vertebral column, with an attachment to the occipital bone of the skull. The rotatores are the deepest muscles in the group and have the shortest fascicles, spanning one to two segments. The cervical-level and lumbar-level rotatores may be represented by deeper fascicles of the multifidus.
The transversospinalis muscles share the same action: bilateral contraction extends the spine, while unilateral contraction rotates the vertebral column to the opposite side. The semispinalis capitis, for example, pulls the head posteriorly during unilateral contraction and rotates the chin to the same side as the contracting muscle. The multifidus muscle plays a crucial role in spinal stability, and its weakness is associated with low back pain.

The muscle spans the whole length of the vertebral column
The multifidus muscle is a group of short, triangular muscles that form part of the transversospinales muscle group. The muscle is located in the deep layer of deep muscles in the back, and it spans the entire length of the vertebral column, from the cervical region to the lumbar region.
The multifidus muscle is composed of fleshy and tendinous fasciculi, which fill the groove on either side of the spinous processes of the vertebrae. These fasciculi vary in length, with the most superficial and longest passing from one vertebra to the third or fourth above, while the deepest connect two adjacent vertebrae. The muscle is innervated by the medial branches of posterior rami of spinal nerves in the corresponding cervical, thoracic, and lumbar regions.
The primary function of the multifidus muscle is to provide support and stability to the spine, particularly the lumbar spine. It accomplishes this by controlling the movement of individual vertebrae, preventing excessive motion, and maintaining proper alignment. The multifidus muscle also aids in several movements of the vertebral column. When contracting bilaterally, the muscle extends the spine, while unilateral contraction aids in lateral flexion and rotation of the spine to the opposite side.
The multifidus muscle is a vital muscle for spinal health and mobility. However, it is often overlooked, and its degeneration can lead to back pain and core issues. Weakness in the multifidus muscle can be caused by physical inactivity, poor posture, and lifestyle choices such as prolonged sitting. It is important to maintain the strength of the multifidus muscle through exercises, stretching, and manual treatments with a physiotherapist.

Multifidus muscle degeneration can cause lower back pain
The multifidus muscle is a long, narrow muscle that runs on either side of the spinal column. It is one of the transversospinales muscles, which fill the groove on either side of the spinous processes of the vertebrae. The multifidus muscle spans the whole length of the vertebral column but is most developed in the lumbar area. Its main role is to stabilise the lower portion of the spine, also known as the lumbar spine.
There are several ways to strengthen the lumbar multifidus muscle. One way is to tense the pelvic floor muscles for a few seconds "as if stopping urination midstream". Another way is to lie on your side with your elbow directly beneath your shoulders, with your legs stacked, and lift your hips off the ground, creating a straight line from your head to your feet.
If you are experiencing lower back pain, it is recommended to book an appointment with a physiotherapist to assess your back strength and movement of the spine. They can work with you to identify the true cause of your back pain and determine the steps required to treat it.

The muscle can be strengthened through physiotherapy
The multifidus muscle is a long, narrow muscle that runs on either side of the spinal column. It is one of the deepest muscles in the back and plays a vital role in spinal health and function. It is responsible for stabilising the vertebrae as the spine moves and is active during all anti-gravity activities.
Weakness or dysfunction in the multifidus muscle is associated with low back pain and core issues. This can cause strains in other muscles due to incorrect movements and injuries. Multifidus degeneration is often overlooked, but targeted exercises can strengthen and activate the muscle, promoting stability and enhancing overall spinal health.
One way to strengthen the multifidus muscle is by isolating it and learning to co-contract it with the other muscles of the core. This can be done by lying on your back or side with a neutral spine and gently lifting the lumbar vertebra 1mm above the one below. Another exercise to target the multifidus muscle is to lie on your side with your elbow directly beneath your shoulder and legs stacked. Then, lift your hips off the ground, creating a straight line from your head to your feet.
Additionally, the multifidus muscle can be activated and strengthened by using a peanut roller to loosen the muscle before exercising. This can help to reduce tightness and fibrosis in the muscle. Specific exercises that target the multifidus muscle include maintaining a neutral spine on your hands and knees and performing repetitions of lifting your arms, chest, and legs off the ground while engaging your core.
