What is the function of the rotatores muscles?
The rotatores muscle, along with the multifidus and semispinalis muscles, facilitates the unilateral rotation (turning from side to side) and bilateral extension (bending backward and forward) of the spine.
Where is rotatores muscles located?
thoracic region
The rotatores muscles (rotatores spinae muscles) lie beneath the multifidus and are present in all spinal regions but are most prominent in the thoracic region; they are eleven in number on either side. The rotatores muscles as viewed from behind.
Are rotatores deep muscles?
The rotatores are the deepest muscles in the transversospinalis group, the deep layer of the intrinsic back muscles. These muscles lie between the transverse and spinous processes and are grouped by length of the fascicles, as well as region covered. The groups are rotatores, multifidus, and semispinalis.
Are rotatores deep to multifidus?
Rotatores. Rotatores muscle lies deep to the multifidus and spans the whole length of the vertebral column, it is most developed in the thoracic region.
What causes multifidus pain?
Multifidis Problem Causing Pain and Dysfunction The back bones are out of control and there’s too much sloppy motion. All of the extra movement can damage the disc spacer between the bones and the joints between them (facet joints), causing pinching of the spinal nerves.
What are the deepest back muscles?
The levatores costarum, interspinales and intertransversarii muscles form the deepest layer of the deep back muscles and are sometimes referred to as the segmental muscles or the minor deep back muscles.
What is the deepest back muscle?
How do you activate multifidus muscle?
Activation
- Start standing with one foot in front of the other.
- To palpate the multifidus, place your thumb right next to the spine on the low back.
- Shift your weight forward and allow your heel to come off the ground.
- You should feel the multifidus pop into your thumb as it contracts.

Paraspinal Stretch: Begin on your hands and knees. Sit back on your heels, keeping your hands flat on the floor. You should feel the stretch down the length of your back. Hold for 20 seconds repeat 3 times.
What is Christmas Tree muscle?
The erector spinae are the group of muscles that form the Christmas tree shape on your back. That Christmas tree isn’t just meant to show off on the competitive bodybuilding stage, but it also means that you have strong lower back muscles as well.
What happens with a weak multifidus?
The multifidus muscle is an important stabilizer of the lumbar spine. It functions together with transversus abdominis and pelvic floor muscles for spine stability. Multifidus muscle weakness and atrophy is associated with chronic low back pain.
What causes a weak multifidus?
The multifidus attaches at every vertebra, meaning that it is involved with the stability and health of the spine at every vertebral joint. The weakening of this muscle – from immobility, a sedentary lifestyle or pre-conditions may cause important muscle tissue to be replaced with fat.
