A note on the deep abdominal reflex.
Deep abdominal reflexes were recorded electromyographically in six patients with lesions of the upper motor neuron. The responses were bilateral, usually with identical latencies which ranged from 16.5 to 25 ms. Individual variation was never greater than 2 ms. It is postulated that these bilateral responses of abdominal muscles were independent stretch reflexes and were not mediated across the...
متن کاملIntra-abdominal Pressures during Voluntary and Reflex Cough
BACKGROUND Involuntary coughing such as that evoked from the larynx, the laryngeal cough reflex (LCR), triggers a coordinated contraction of the thoracic, abdominal and pelvic muscles, which increases intra-abdominal pressure (IAP), displaces the diaphragm upwards and generates the expiratory force for cough and airway clearance. Changes in the IAP during voluntary cough (VC) and the LCR can be...
متن کاملNeck circumference as a measure of neck fat and abdominal visceral fat in Chinese adults
BACKGROUND Visceral adipose tissue (VAT) is a unique pathogenic fatty deposit, in that it is closely correlated with risk of cardiovascular diseases. The present study is to investigate the usefulness of neck circumference (NC) to indicate VAT. METHODS Participants aged 35 to 75 years who had taken abdomen and neck computer tomography (CT) examination were included in this study. Neck adipose...
متن کاملEffect of straining on the muscles of the anterior abdominal wall. Identification of the 'straining-abdominal wall reflex'.
The external and internal oblique, transverse abdominis and the rectus abdominis muscles constitute the anterolateral abdominal wall muscles. They are striated and contract voluntarily. We investigated the hypothesis that contraction of these muscles by coughing or straining, can also occur as a reflex. Effect of straining on muscles was tested in 19 healthy volunteers. The intra-abdominal pres...
متن کاملImpaired reflex control of intestinal gas transit in patients with abdominal bloating.
BACKGROUND Patients with abdominal bloating and distension exhibit impaired transit of intestinal gas which may lead to excessive gas retention and symptoms. Furthermore, we have previously shown that intestinal gas transit is normally accelerated by rectal distension. We hypothesise that in patients with functional bloating this modulatory mechanism fails and impairs gas transit. METHODS In ...
