Typical single swallows and drinking of a person with recurrent tonsillitis, age 24 years, (MS, SUB and INF locations). Trials 1–3 – saliva swallows, trials 4–6 – normal swallows, trial 7 – excessive swallow, trial 8 – 100 ml drinking. The SUB peaks are normal (blue line) except trial 1; MS peaks are somewhat high, especially in single swallows being almost similar to the SUB amplitude (green line), INF is very high compare to normal database (red line).
