erector spinae muscle

Three adjacent vertical bands of deep back muscles -- the iliocostalis, longissimus, and spinalis muscles. Origins: a wide tendon running along the iliac crest to the sacrum, the lower lumbar and sacral spinous processes. Insertions: along the back in the angles of the lower ribs, transverse processes of the thoracic and cervical vertebrae. Nerves: dorsal rami of the spinal nerves. Actions: extends (bends backward) the vertebral column and neck, twists the back.

The various erector spinae muscle actions (isometric, concentric and eccentric) during lifting and lowering should also be given suitable consideration when designing back exercise programmes.
Previous studies (Sung et al., 2009; 2013) showed that patients with the chronic low back pain have lower average EMG frequencies in the thoracic part of the erector spinae muscles compared with the lumbar part.
The lifting belt reduced the peak normalized EMG of th e erector spinae muscles on average by 3% during asymmetric loading, though peak normalized EMG was increased by 2% during symmetric loading.

Muscle activity of the upper (UES) and lower (LES) part of the erector spinae muscle, upper (URA) and lower (LRA) part of the rectus abdominis muscle, and splenius muscle (SPL) with different vibration peak amplitudes (1.3 mm and 3.9 mm) and knee angles (30[degrees] and 45[degrees]) during whole-body vibration (WBV) and without vibration stimulus (CON).
EMG activity of the erector spinae muscles were significantly less activated under the "familiar" condition and trapezius and biceps brachii activation was similar between the experimental conditions.
The ROIs were drawn following the contour of the erector spinae muscle on both sides and encompassing trabecular bone of vertebral body (as shown in Figure 1).
Spectral analyses of the EMG data also showed fatigue development of the erector spinae muscles in the majority of participants in all groups.
To reduce tension on iliopsoas bachward through erector spinae muscles causes muscle fatigueness.
Another important aspect refers to the fact that the postural attitude is not conditioned only by the muscle tone, the ligament strength and the erector spinae muscles, but also by the human being's personality, that is why it was called the "psychic drive".
Kyphotic deformity develops at the site of the spinal dysraphism as a result of the lateralised erector spinae muscles becoming perverted flexors of the spine.
Being careful to avoid the vertebrae, roll the ball up and down the erector spinae muscles that run along the sides of the spine while pressing into the wall at the same time.
