The multifidus muscle is a group of short, triangular muscles that are part of the transversospinal muscle group. They are located in the deep layer of deep muscles in the back, just superficially to the spine itself. The multifidus muscles are responsible for controlling the position of the vertebrae, helping to maintain proper posture and spinal stability. When the multifidus muscle is not regularly used and strengthened, it can become weakened and cause lower back pain and core issues.

Multifidus muscle weakness and dysfunction can cause back pain
The multifidus muscle is a group of short, triangular muscles that are part of the transversospinalis muscle group. They are located in the third or deep layer of muscles in the back, just superficial to the spine itself. The multifidus muscle is involved in several movements of the vertebral column, including its extension, lateral flexion, and rotation.
Multifidus muscle dysfunction is a commonly overlooked cause of back pain. It is associated with low back pain and can persist even after the pain has subsided, potentially explaining the high recurrence rates of lower back pain. The inhibition of the multifidus muscle, where it shuts down and weakens, often goes undetected or untreated, leading to chronic low back pain that may be misdiagnosed as "non-specific."
To address multifidus muscle weakness and back pain, physical therapy and exercises are often recommended. These exercises may include stretching, core stability exercises, and full-body movement retraining. Additionally, medication may be prescribed to reduce inflammation, alleviate pain, and relax the muscles, such as non-steroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, and corticosteroids. In severe cases, surgery may be necessary to repair or replace damaged structures in the spine.
Furthermore, neurostimulation techniques, such as ReActiv8, have been developed to aid in the management of chronic low back pain associated with multifidus muscle dysfunction. This involves the implantation of a prescription device by certified physicians.

The multifidus muscle is part of the transversospinales muscle group
The multifidus muscle is a group of short, triangular muscles that make up the transversospinales muscle group, also known as the transversospinal group. This muscle group is responsible for stabilizing the vertebrae during localized movements of the intervertebral joints of the vertebral column.
The multifidus muscle is located in the third or deep layer of deep muscles in the back. It lies deep relative to the spinal erectors, transverse abdominis, abdominal internal oblique muscle, and abdominal external oblique muscle. The multifidus is innervated by the medial branches of the posterior rami of spinal nerves in the corresponding cervical, thoracic, and lumbar regions.
The multifidus muscle is composed of many short, triangular muscles that span the entire length of the vertebral column. It is found on either side of the vertebral column, extending from the cervical region to the lumbar spine. The group is regionally divided into cervical multifidus, thoracic multifidus, and lumbar multifidus.
Each multifidus muscle bridges over three to six vertebral levels, spanning between the transverse and spinous processes of certain cervical, thoracic, and lumbar vertebrae. Although the multifidus muscles are small, they aid several movements of the vertebral column. When contracting bilaterally, they extend the spine, while unilateral contraction aids lateral flexion of the spine to the same side and rotation of the spine to the opposite side.
The multifidus muscle plays an important role in spinal health and mobility. Dysfunction in the lumbar multifidus muscles is strongly associated with low back pain. Therefore, it is essential to regularly strengthen the multifidus muscle through exercises or physiotherapy to prevent weakness and maintain spinal stability.

The multifidus muscle is responsible for controlling the position of the vertebrae
The multifidus muscle is a group of short, triangular muscles that form part of the transversospinal muscle group. These muscles are located in the deep layers of the back, beneath the erector spinae, transverse abdominis, and abdominal internal and external oblique muscles. The multifidus is one of the transversospinales, and it spans three joint segments, working to stabilize the joints at each level.
The multifidus muscle is a local core stabilizer, and weakness or dysfunction in this muscle is associated with low back pain. When the multifidus is inhibited, it will atrophy and degenerate over time, leading to a replacement of normal lean muscle tissue with intramuscular fatty deposits. This can cause pain and instability in the lower back and core, as well as strain on other muscles due to incorrect movements and compensations.
To strengthen the multifidus muscle, specific exercises can be performed, such as those prescribed by a physiotherapist or core stabilization programs. These exercises may include stretching, motor control exercises, and general full-body movement retraining. By maintaining the strength of the multifidus muscle, individuals can help prevent back pain and improve spinal health and mobility.

Multifidus muscle degeneration can be caused by inhibition of pain by the spine
The multifidus is a group of short, triangular muscles that are part of the transversospinal muscle group. They are located in the third or deep layer of muscles in the back, just superficially to the spine, extending from the cervical to the lumbar spine. The multifidus muscle plays a vital role in spinal health and mobility, providing stiffness and stability to the vertebrae, and reducing degeneration of the joint structures caused by friction from normal physical activity.
However, when the multifidus muscle is not regularly used and strengthened, it can become weakened and dysfunctional, leading to lower back and core issues. Dysfunction in the lumbar multifidus muscles is strongly associated with low back pain (LBP). This dysfunction can be caused by inhibition of pain by the spine, resulting in an inhibitory feedback loop that leads to atrophy and fatty replacement of the muscle. The atrophy of the multifidus muscle decreases its ability to control the lumbar spine neutral zone, contributing to the high recurrence rate of LBP.
Multifidus degeneration can be caused by several factors, including disc degeneration, Modic type 1 or 2 marrow changes, and vertebral endplate defects. These degenerative processes may contribute to recurring episodes or long periods of back pain, which can further inhibit muscle activity and impact the quality of the multifidus muscle. Spinal degeneration has been associated with lumbar multifidus morphology in patients with low back or leg pain, indicating a potential complex inter-relationship between the two.
The persistence of lumbar multifidus dysfunction, even after the resolution of pain, can be diagnosed through magnetic resonance imaging (MRI) or ultrasound, which reveal the atrophic replacement of the multifidus with fat. To address multifidus muscle degeneration, muscle training directed at teaching patients to activate their multifidus muscles is crucial. Specific exercises, such as stabilization training and dynamic resistance, have been shown to increase the cross-sectional area of the multifidus muscle at all vertebral levels. Additionally, working with a physiotherapist through manual treatments, stretching, and exercise can help maintain and strengthen the multifidus muscle, improving spinal health and reducing back pain.

The multifidus muscle can be strengthened through exercises
The multifidus muscle is a group of short, triangular muscles that are part of the transversospinal muscle group. They are located in the deep layer of muscles in the back and play a crucial role in stabilising the joints within the spine. The multifidus muscles help to reduce degeneration of the joint structures caused by friction from normal physical activity.
A weak multifidus muscle can lead to various health issues, particularly lower back pain and core instability. When the lumbar multifidus muscle is weakened, it cannot effectively stabilise the spine, which can result in strains to other muscles, injuries, and pain in the lower back and spine due to incorrect movements.
However, the good news is that the multifidus muscle can be strengthened through exercises. It is important to work with a physiotherapist or a qualified professional to assess your back strength and spinal health. They can guide you through manual treatments, stretching, and exercises to help maintain and strengthen your multifidus muscle.
- Bird Dog Exercise: This is a commonly prescribed exercise that targets the multifidus muscle. Start on your hands and knees with your hands directly under your shoulders and your knees directly under your hips. Lift one leg, keeping it straight, and hold this position for 10 seconds. Slowly lower it back down and repeat on the other side.
- Quadruped Leg Lift: This exercise engages the core and challenges your balance. Begin in the same starting position as the Bird Dog exercise. Lift one leg off the ground while keeping your knee bent. Hold this position for 10 seconds and then slowly lower it back down. Repeat on the other side.
- Dumbbell Row: Using a weights bench or a table, place one leg back and lean forward from your waist until your upper body is parallel to the floor. Support yourself by placing your hand on the bench. Pick up a dumbbell from the floor with the other hand and hold it with a straight back. Pull the dumbbell straight up to your chest and keep your torso still. Lower the weight back down to the starting position.
- Bridge with Leg Extension: Lie on your back with your spine in a neutral posture. Lift your hips off the ground, creating a straight line from your shoulders to your knees. Hold this position for 20-30 seconds and then slowly lower back down.
- Core Stability Exercises: Focus on your posture and engage your glutes and abdominals to extend your left arm and right leg out simultaneously. Hold this position for 10 seconds and then return to the starting position. Repeat with the right arm and left leg extension.
By incorporating these exercises into your routine, you can help strengthen your multifidus muscle, improve your spinal stability, and reduce the risk of injuries and back pain.
