Description
<p>Purpose: Thermal-tactile stimulation (TTS) is an indirect training method for dysphagia. Some reports have shown that TTS increases the sensitivity to induce swallowing, while others have demonstrated that the effect does not always appear. In addition, the benefit and mechanism of the effect of TTS remains to be elucidated. In this study, to investigate the effect of TTS, a frozen cold cotton swab was used as a stimulant, and the influence on latency before the swallowing reflex induced by droplets of water was examined.</p><p>Subjects and Methods: The subjects were 10 healthy young adults with no eating or swallowing problems. After saliva was swallowed, water was dropped at 1.0 ml/min to the posterior part of the back of the tongue and latency before the induction of swallowing reflex was measured five times. After a rest, TTS was performed, and latency before swallowing reflex induced by droplets of water was measured five times. Latency was compared before and after TTS.</p><p>Results: The average of the latency in 10 subjects measured before and after TTS was 13.8±6.7 s and 11.2±5.6 s, respectively, and latency was significantly reduced after TTS (p<0.05). The average latency was 11.3±4.7 s at the first measurement, 10.7±5.1 s at the second, 11.7±6.9 s at the third, 11.2±5.8 s at the fourth, and 11.4±5.5 s at the fifth measurement (about 10 min after TTS). After TTS, the latency was significantly reduced at each measurement (p<0.05).</p><p>Conclusions: Latency before swallowing reflex was reduced immediately after TTS, and the effect continued for at least 10 min. These results indicate that TTS hastens the beginning of the swallowing reflex and suggest that it is an effective training method for dysphagia.</p>
