BACKGROUND The mechanisms by which the abdominal muscles move and control the lumbosacral spine are not clearly understood. Descriptions of abdominal morphology are also conflicting and the regional anatomy of these muscles has not been comprehensively examined. The aim of this study was to investigate the morphology of regions of transversus abdominis and(More)
Biomechanical models predict that recruitment of gluteus maximus (GMax) will exert a compressive force across the sacroiliac joint (SIJ), yet this muscle requires morphologic assessment. The aims of this study were to document GMax's proximal attachments and assess their capacity to generate forces including compressive force at the SIJ. In 11 embalmed(More)
The objectives of this study were to investigate the anatomical relationship between the proximal adductor longus (AL) and rectus abdominis muscles and to determine whether unilateral loading of AL results in strain transmission across the anterior pubic symphysis to the contralateral distal rectus sheath. Bilateral dissections were conducted on 10 embalmed(More)
BACKGROUND There are many theories as to lower limb fascial function including the hydraulic amplifier effect 1 with respect to lumbar fascia, the crossover effect in support of bipedal motion 2 and tensioning theory 3. Schleip,et al 4 have demonstrated contractile properties of fascia and Barker 5 and others have demonstrated discrete collagen fiber(More)
