Mechanical role of the abdominal muscles in relation to posture

Respiration Physiology, 1983
Abdominal muscle activity was studied in 10 normal naive subjects during quiet breathing in different body positions. Electromyograms of the upper and lower portions of the external oblique and rectus abdominis were recorded with bipolar needle ...

The Anatomy of the Abdominal Muscles of the Chinchilla

Research in Veterinary Science, 1967
SUMMARY The abdominal muscles of the male and female chinchilla are described and illustrated. An external inguinal ring is present, but the extensive contributions of internal oblique and transverse abdominal muscles to the cremasteric sac make it difficult to define clearly the internal inguinal ring.

Co-activation of the abdominal and pelvic floor muscles during voluntary exercises

Neurourology and Urodynamics, 2001
The response of the abdominal muscles to voluntary contraction of the pelvic floor (PF) muscles was investigated in women with no history of symptoms of stress urinary incontinence to determine whether there is co-activation of the muscles surrounding ...

Postoperative Abdominal Muscle Spasm

Archives of Surgery, 1957
Every laparotomy is followed by several days of discomfort, but postoperative pain varies greatly among patients. Such discomfort may include (1) ordinary abdominal wall pain due to cutting and retraction of nerves and muscles; (2) distention of the gastrointestinal tract because of ileus, an almost invariable accompaniment of intraabdominal surgery ...

The Abdominal Muscles and Vertebral Stability

Spine, 1987
It has been suggested that the muscles of the anterolateral abdominal wall increase the stability of the lumbar region of the vertebral column by tensing the thoracolumbar fascia and by raising intra-abdominal pressure. In this report these new mechanisms are reviewed and their contribution to vertebral stability assessed.

Abdominal Muscle Strength in Patients with Tetraplegia.

Cardiopulmonary Physical Therapy Journal, 2000
Abstract The abdominal muscles are completely paralyzed after traumatic transection of the cervical cord. To assess the residual pressure-generating capacity of these muscles, we first measured the changes in gastric pressure ( Δ Pga) during paired bilateral stimulation of the lower thoracic nerve roots in eight chronic patients with ...

Control of abdominal muscles

Progress in Neurobiology, 1998
Abdominal muscles serve many roles; in addition to breathing, especially at higher levels of chemical drive or at increased end-expiratory lung volumes, they are responsible for, or contribute to, such protective reflexes as cough, sneeze, and vomiting, generate the high intra-abdominal pressures necessary for defecation and parturition, are active ...

TRANSVERSE AND MUSCLE-SPLITTING ABDOMINAL INCISIONS

Archives of Surgery, 1953
A RECENT survey of over 500 certified surgeons in this country revealed that only about 26% are employing transverse or muscle-splitting abdominal incisions for the common types of abdominal operations.1It appears therefore that the majority of surgeons and most of the other physicians performing surgery are using midline or paramedian incisions.

Hernia Due to Banding of the Abdominal Muscles

Archives of Surgery, 1968
SUPERIMPOSED parallel slits between bands of the internal oblique and transversus abdominis muscles occasionally open to allow formation of a hernia at the level of the semicircular line of Douglas, which enters a shallow subaponeurotic space lateral to the rectus sheath and deep to the aponeurosis of the external oblique.

Phasic stretch reflex of the abdominal muscles

Experimental Neurology, 1986
This analysis of the abdominal stretch reflex (ASR) evoked by a tap to the abdomen was designed to explore how abdominal motoneurons process signals from respiratory and nonrespiratory sources. We recorded surface EMGs from the external and internal oblique muscles in standing subjects. Amplitudes of the abdominal stretch reflex varied despite constant
