Consistency in size and asymmetry of the psoas major muscle among elite footballers
British Journal of Sports Medicine, 2009 ObjectiveTo determine, using magnetic resonance imaging (MRI), the cross-sectional area (CSA) of the psoas major (PM) muscle across multiple vertebral levels, to examine any asymmetry of the PM muscle and investigate the consistency across vertebral levels, and to determine whether a relationship exists between low back pain (LBP) and the size or ...

The FASEB Journal, 2022
Introduction & Objective The psoas minor muscle is found in the retroperitoneum with close association to the psoas major and iliacus muscles. Major anatomical textbooks fail to offer a clear consensus on psoas minor, providing conflicting information on the insertion site, function, and relationship to the ...

Anatomy and biomechanics of psoas major
Clinical Biomechanics, 1992The fascicular anatomy of the psoas major was determined by dissection in three cadavers. Its actions on the lumbar spine in the sagittal plane were modelled on erect, flexion, and extension radiographs of ten adult males. Calculations revealed that psoas exerts only very small moments that tend to extend the upper lumbar spine and to flex the lower ...

The principal artery of the psoas major muscle
Surgical and Radiologic Anatomy, 1989The psoas major m. has a complex arterial supply, derived from the lumbar, iliolumbar, obturator, external iliac and common femoral a. The branches arising from the external iliac a., though quite often multiple and slender, are represented in 75% of cases by a single large-caliber vessel. This principal artery of the psoas m.

Lumbar Plexus and Psoas Major Muscle
Regional Anesthesia and Pain Medicine, 2008Background and Objectives: Conflicting definitions concerning the exact location of the lumbar plexus have been proposed. The present study was carried out to detect anatomical variants regarding the topographical relation between the lumbar plexus and the psoas major muscle as well as lumbar plexus anatomy at the ...

Psoas major and its controversial rotational action
Clinical Anatomy, 1999The action of psoas major muscle as a primary flexor of the hip joint is undisputed. However it is also variably reported as being a medial and a lateral rotator of the femur at the hip joint. The psoas and iliacus muscles, along with their common insertion, were isolated by dissection in six adult cadaveric specimens.

Direct Electromyography of the Psoas Major Muscle in Man
The Journal of Bone & Joint Surgery, 1966Electromyographic studies of the psoas major muscle were performed on five patients with wire electrodes implanted directly into the muscle during lumbar sympathectomy. Recordings made during various activities, approximately ten days after operation, indicated that this muscle has a regular and significant role in advancing the limb while walking and ...

The Role of the Psoas Major Muscle in Speaking and Singing
Voice and Speech Review, 2021Even though the psoas major muscle function is a frequent topic in sports and clinical science, there is a gap in the literature regarding its role in speaking and singing.

The psoas major muscle: A three-dimensional geometric study
Journal of Biomechanics, 1995The purpose of this study was to use anatomical data obtained from cadavers, and geometrical scaling data obtained from MRI scans of living subjects, to assess the line of action and mechanical function of the psoas major muscle in three dimensions about each lumbar spine level.
