Muybridge made his most important photographic studies of motion from 1884 to 1887 under the auspices of the University of Pennsylvania. These consisted of photographs of various activities of human figures, clothed and naked, which were to form a visual compendium of human movements for the use of artists and scientists.
The movement of bolus is measured in patients who have subtle flow disorders. Pharyngeal Manometry tests the muscle contractions and coordination of esophagus peristalsis. Upper Esophageal Sphincter (UES) Manometry tests UES tone, pressure, and relaxation. The UES may fail to relax or be unsynchronized with the pharynx causing peristaltic dysfunction or the sensation of an object being stuck in the throat. Esophageal Body Manometry tests the muscle contractions and esophagus peristalsis. Lower Esophageal Sphincter (LES) Manometry tests sphincter tone and relaxation ability. High-resolution esophageal manometry testing utilizes a small tube containing solid state pressure sensors. The tube is inserted through the nose into the esophagus to measure esophagus contractions and the relaxation of the LES.
