What is thermal stimulation?
A stimulus produced by a change in skin temperature, a rise giving sensations of warmth, a fall giving sensations of coldness. See also: stimulus.
When do you use thermal tactile stimulation?
Thermal-tactile stimulation (TTS) is a technique used on patients with oropharyngeal dysphagia to increase sensitivity in the oral cavity and trigger a faster swallowing reflex(12). Cold temperatures or ice are used to provide sensory stimulation to the anterior faucial pillars(13,14).
How do you do thermal gustatory stimulation?
Thermal gustatory stimulation (TGS) therapy – This technique involves pressing a cold metal object against the back of the throat to elicit a swallow response. Improvements in swallowing functionality are generally temporary.
What is DPNS in dysphagia?
Deep pharyngeal neuromuscular stimulation (DPNS) is a noninvasive, electrical stimulation therapy for people with dysphagia (difficulty swallowing). Therapists are certified to perform this therapy.
What is chemical stimulation?
activity or a change of activity generated in olfactory (smell) or gustatory (taste) receptor cells by contact with specific electrolytes or molecules. Both chemical senses have specialized receptor proteins to which stimulating molecules bind to create electrical potentials.
What is an example of mechanical stimuli?
Mechanoreceptors respond to physical movement in the receptor. This can result from water currents, sound, body movements, pressure or gravity. Mechanical stimuli are hard to record without interfering with the stimulus itself, particularly stimuli from touch or small turbulent water movements.
How do you trigger a swallow reflex?
The swallowing reflex is triggered by mechanical or chemical stimulation of the soft palate, uvula, dorsum of the tongue, or posterior wall of the pharynx [19].
How do you promote swallowing?
As example, you may be asked to:
- Inhale and hold your breath very tightly.
- Pretend to gargle while holding your tongue back as far as possible.
- Pretend to yawn while holding your tongue back as far as possible.
- Do a dry swallow, squeezing all of your swallowing muscles as tightly as you can.
