We made a barium containing jelly(here after referred to as Ba-jelly)for use in video fluoroscopy(VF)of the elderly patients and measured its physical properties with a hardness testing device. A video fluoroscope was used to observe healthy adult subjects when they ingested and swallowed the Ba-jelly. Incorporating a greater amount of gelatin of barium increased the hardness of the Ba-jelly. We also found that the Ba-jelly was harder at 4℃ than at 24℃. Examination of mastication of Ba-jelly using VF was easier when it had a higher content of barium. However, it was easier for the subjects to ingest and swallow Ba-jelly of lower hardness. These results gave us valuable insights into the physical properties of Ba-jelly and how it can be used in VF of elderly subjects.
