2009) and Sung (2013) stated that the average electromyography (EMG) frequency of the thoracic part of the erector spinae muscles of patients with chronic low back pain is significantly lower with respect to the lumbar part than that of healthy individuals with no chronic low back pain.
Once habituated, surface EMG (sEMG) electrodes were placed on the participants' right lower erector spinae, rectus abdominis, biceps femoris, gastrocnemius and rectus femoris muscles, as detailed in studies by Silfies et al.
High-heeled shoes tip the body forwards and interfere with normal coordination of muscles that stabilise the lower spine (abdominal muscles, erector spinae, and gluteus maximus).
10,11) A protocol was established to mea sure muscle activation for bilateral rectus abdominus, external oblique, erector spinae, and latissimus dorsi as percentages of maximal voluntary isometric contraction.
The lesion also involved the right quadratus lumborum muscle and the right erector spinae muscle [Figure 1]b.
These are made up of several muscle groups: The "abs" at the front of your abdomen; the internal and external obliques in the front and sides of the abdomen; the transversus muscles that run horizontally across your lower abdomen, the erector spinae (the large muscles on either side of your spinal core), the scapulae (the muscles that surround your shoulder blades), the gluteus muscles in your hips and buttocks, and the iliopsoas and quadratus lumborum muscles in your pelvis.
The erector spinae muscle around the vertebral body was selected as the reference region because its big muscle bulk is easy to be recognized in the images and would be able to derive the DCE-MRI signal with a good signal-to-noise ratio (SNR).
Lumbar erector spinae electrodes were placed 4 cm lateral to the L3 spinous process.
A change in lumbar curvature can alter fascicle obliquity, lever arm distance, and the length-tension relationships of the erector spinae (McGill et al 2000, Raschke and Chaffin 1996, Singh et al 2011, Tveit et al 1994).
Stiffness and tone (frequency of muscle oscillations) of the both left and right sides of the lumbar erector spinae (ER) and gluteus medius (GM) muscles were investigated.
2,5,8) Golfers who have low back pain demonstrate earlier activation (before backswing commences) and less activity of the erector spinae muscles, as well as well as a delay to the onset time in the external obliques with the start of the back swing and a delay and decreased endurance capacity in transverses abdominus activation.
hamstrings, hip extension), posterior adductor magnus (hip extension), gluteus maximus (hip extension), gluteus medius (hip abduction), and erector spinae (trunk extension).
