Also, a large majority of athletes have tears or disruptions of the external oblique
fascia, especially where the branches of the ilioinguinal and iliohypogastric nerves exit the fascia.
The anterior wall is formed by the aponeurosis of the external oblique
Electrodes were placed 2 cm apart and parallel to the fiber direction of the external oblique
on the same side as the lead leg used for the MUS.
Similarly, using both M-mode ultrasound and tissue doppler imaging of transversus abdominis, internal oblique, and external oblique
, Vasseljen et al (2009) found a systematic delay of muscle onset with both techniques compared with EMG ranging from 2 to 15 ms, except for external oblique
which contracted 54 ms earlier according to ultrasound compared with EMG.
At surgery, a transverse incision was made in the left lower quadrant through the aponeurosis of the external oblique
muscle and the medial third of the rectus muscle.
Abdominal muscles: The four abdominal muscles (rectus abdominus, external oblique
, internal oblique, and transverse abdominus) serve to flex the thorax, rotate and laterally flex the vertebral column, and compress the abdominal region.
CT scan revealed a mass of 21x13x11 cm located between the abdominal subcutaneous and external oblique
EMG analysis- For this exercise, the predominant muscle activity was for rectus abdominus and external oblique
Furthermore, the internal and external oblique
muscles as well as rectus abdominis are also transected during Caesarean section.
1,2) Injury typically occurs at either the superior lumbar (Grynfeltt-Lesshaft) triangle, which is bordered by the 12th rib superiorly, erector spinae muscle posteriorly, and internal oblique muscle anteriorly; or the inferior lumbar (Petit's) triangle, which is bordered by the iliac crest inferiorly, external oblique
muscle anteriorly, and latissimus dorsi muscle posteriorly.
Some of the more common presentations of musculoskeletal pelvic pain are hyperirritability in the rectus abdominus muscle, the overlying fascia, or the subcutaneous tissue of the lower abdomen overlying the external oblique
Abdominals: The four abdominal muscles (rectus abdominus, external oblique
, internal oblique, and transeverse abdominus) serve to flex the thorax as well as rotate and laterally flex the vertebral column.
The anterior rectus sheath is incised at right angles to the skin incision from pubic symphysis extending if necessary into the external oblique
Washburn has a strained left external oblique
muscle, just below the rib cage.
They are composed largely of three different muscles: the rectus abdominals, the internal oblique, and the external oblique
