Many bilateral motor tasks engage simultaneous activation of distal and proximal arm muscles, but little is known about their physiological interactions. Here, we used transcranial magnetic stimulation to examine motor-evoked potentials (MEPs), interhemispheric inhibition at a conditioning-test interval of 10 (IHI(10)) and 40 ms (IHI(40)), and short-interval intracortical inhibition (SICI) in t...
The latissiimis dorsi muscle (LDM) receives its primary blood supply from a single nutrient artery located at its proximal insertion and it has not previously been established whether this effects the regional perfusion and nutrition of the muscle, A microelectrode technique was used to measure local oxygenation and permsion simultaneously at multiple sites in the rabbit LDM at rest, during and...
BACKGROUND Some patients with achalasia have distal esophageal contraction amplitude in the normal range, a condition called vigorous achalasia, and others have low contraction amplitude, a condition named classic achalasia. The difference in distal contraction amplitude may also be associated with a difference in proximal contraction amplitude. AIM To study the proximal and distal esophageal...
To elucidate the altered function of the lower esophageal sphincter (LES) in gastroesophageal reflux disease (GERD), we evaluated the motility proximal to LES using force transducers, contraction and relaxation responses to neurotransmitters in LES strips, and gene expression of neurotransmitter receptors in GERD rats. Force transducers were applied to the proximal LES, and contraction of the L...
PURPOSE To evaluate and correlate the amplitude of esophageal contractions triggered by swallowing water with dynamic extension and habitual, strong and weak sound intensity in total laryngectomees wearing a tracheoesophageal prosthesis. METHODS Thirty total laryngectomees using tracheoesophageal voice with a phonatory prosthesis were evaluated by measuring the amplitude of contractions in th...
