Geometry of Adult Rectus Abdominis and Erector Spinae Muscles [PDF]

Journal of Orthopaedic & Sports Physical Therapy, 1985
Mathematical modeling of human joints requires accurate information concerning anthropometric parameters such as muscle cross-sectional areas and muscle moment arms. The purpose of this study was to calculate the average crosssectional area, average volume, and length of the muscle moment arms about the spinal column for the rectus abdominis (RA) and ...

Relationship between Vertebral Instability and the Cross-Sectional Area of Lumbar Muscles in Postmenopausal Acute Osteoporotic Vertebral Fractures

Spine Surgery and Related Research, 2022
Introduction: Vertebral instability (VI) in osteoporotic vertebral fractures (OVFs) varies from mild to severe. The relationship between the VI of OVFs and independent factors, such as bone mineral density (BMD) and lumbar muscle volume, is unclear. This

Determining the optimal maximal and submaximal voluntary contraction tests for normalizing the erector spinae muscles. [PDF]

PeerJ, 2019
Background This study aimed to identify which maximum voluntary isometric contraction (MVIC) and sub-MVIC tests produce the highest activation of the erector spinae muscles and the greatest reduction in inter-individual variability, to put them forward as reference normalization maneuvers for future studies.
