In humans, when the stability of the trunk is challenged in a controlled manner by repetitive movement of a limb, activity of the diaphragm becomes tonic but is also modulated at the frequency of limb movement. In addition, the tonic activity is modulated by respiration. This study investigated the mechanical output of these components of diaphragm activity. Recordings were made of costal diaph...

[Purpose] Continuous electrical stimulation of abdominal wall muscles is known to induce mild muscle fatigue. However, it is not clear whether this is also true for functional electrical stimulation delivered only during the expiratory phase of breathing. This study aimed to examine whether or not intermittent electrical stimulation delivered to abdominal wall muscles induces muscle fatigue. [S...

AIMS The aim of the study was to investigate the reliability of a scoring system for the investigation of voluntary and reflex co-contractions of abdominal and pelvic floor muscles in lying, sitting, and standing positions in continent and incontinent women. METHODS A visual inspection and digital (strength, tone, speed, and endurance) palpation scale was developed to measure the coordination...

Oxford Medical Publications. 1918. bs. net.?The writer has made observations on the normal living subject, and sets out to prove a physiological theory. He commences by demonstrating that in " starting " from surprise, or at the beginning of all effort, the abdominal muscles contract in such a way as to drive as much blood as possible derived from the liver and ductless glands through the muscl...

[Purpose] The purpose of this study was to investigate the effects of abdominal bracing with low extremity movement on changes in thickness of abdominal muscles and lumbar strength. [Subjects] Sixteen patients with chronic low back pain were randomly assigned to two groups: an abdominal bracing with active straight leg raise (ABSLR) group and abdominal bracing with ankle dorsiflexion (ABDF) gro...

Co-contraction of abdominal muscles (abdominal bracing) is considered an effective exercise technique for improving spinal stability, and is often recommended and/or included in rehabilitation and/or fitness programs (Maeo et al., 2013b). Abdominal bracing has been shown to induce higher activation in deep abdominal muscles such as transversus abdominis and internal oblique muscles, which are c...

QUESTION Do different sitting postures require different levels of pelvic floor and abdominal muscle activity in healthy women? DESIGN Observational study. PARTICIPANTS Eight parous women with no pelvic floor dysfunction. OUTCOME MEASURES Bilateral activity of pelvic floor muscles (assessed vaginally) and two abdominal muscles, obliquus internus abdominis and obliquus externus abdominis, ...

Herpes zoster (HZ) is caused by the reactivation of varicella-zoster virus (VZV), which has ability to remain latent in neural tissue. We report a case rare complication, abdominal pseudohernia, developed 63-year-old woman, partial protrusion wall due paralysis muscles.

STUDY DESIGN Cross-sectional study. OBJECTIVE Comparison of the timing of onset of lateral abdominal muscle activity during rapid arm movements in patients with nonspecific chronic low back pain (cLBP) and back-pain-free controls. SUMMARY OF BACKGROUND DATA Rapid movements of the arm are normally associated with prior activation of trunk-stabilizing muscles in readiness for the impending po...

present research was for study on parasitic infections of domestic ruminants in golestan province. 234 samples of the gastrointestinal tracts contents, 260 livers, 180 lungs, 350 hearts and muscles, 300 abdominal cavities and 100 eyes for infection to helminthes, 800 blood samples for protozoa and external coats of 700 animals were examined for arthropoda. results showed that 19.74% of sheep ga...
