An intersegmental reflex initiated by flexing a crayfish leg at the merocarpal joint was examined by recording reflex response latencies of cephalic, thoracic and abdominal muscles. The first response was an intrasegmental resistance reflex in the extensor muscle of the stimulated leg. Spread of the intersegmental reflex occurred in both cephalic and caudal directions. Activation of the cephali...

Abdominal muscles, such as the oblique- and transverse muscles, find their blood supply from multiple segmental pedicles from the iliac artery. Besides its superior vascularization, its release is simple, leaving two abdominal muscles for securing abdominal wall strength. The release of the muscle and coverage of the graft requires partial muscle mobilization and is a minor reconstruction, but ...

The pelvic floor muscles (PFM) are part of the trunk stability mechanism. Their function is interdependent with other muscles of this system. They also contribute to continence, elimination, sexual arousal and intra-abdominal pressure. This paper outlines some aspects of function and dysfunction of the PFM complex and describes the contribution of other trunk muscles to these processes. Muscle ...

Abdominal diastasis is a condition that occurs when the rectus abdominis muscles separate, leading to weakness in abdominal wall and can manifest as bulge middle abdomen. common generate annoying symptoms affect quality of life those who suffer from it. Management include variety therapeutic approaches, conservative management with specific exercises manual therapy, surgery more severe cases.

BACKGROUND AND PURPOSE Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. A model involving evaluation of the response of the lumbar multifidus and abdominal muscles to leg movement was developed to evaluate this function. SUBJECTS To examine this function in healthy persons, 9 male and 6 fem...

OBJECTIVES To evaluate the effect of lumbopelvic belts on the thickness of lateral abdominal muscles and the cross-sectional area (CSA) of lumbar multifidus (LM) muscles. DESIGN A single-blinded randomized controlled trial. SETTING An academic and tertiary care referral spine and sports medicine center. PARTICIPANTS Sixty healthy volunteers with no history of low back pain in the previous...
