We previously found acute administration of TRP sensory stimulants improved VFS signs and swallow response. We hypothesized that sub-acute administration of TRP pharyngeal sensory stimulants, would improve cortical neuroplasticity and will lead into a faster and stronger swallow response, however desensitization of TRP receptors may occur. Therefore, the aim of the present study was to assess the biomechanical (Videofluoroscopy) and neurophysiological (pharyngeal sensory evoked potentials -PSEPs- and motor-evoked potentials (MEPs)) effect of 2 week treatment with TRP agonists in older patients with OD. Design: 150 older (\\>70yr) patients with OD will be included in a Randomized Control Trial assessing the effect of oral administration of either: a) capsaicin (TRPV1); b) piperine (TRPV1/TRPA1) c) cinnamaldehyde (TRPA1); d) citric acid (ASIC3); e) capsaicin+citric acid (TRPV1/ASIC3); and f) placebo (Control). Measurements: 1) VFS signs of safety and efficacy of swallow and timing and extent of swallow response; 2) Latency, amplitude and cortical representation of PSEP and MEP; 3) Substance P concentration in saliva by ELISA as a marker of peripheral stimulation. Results from this study might help to develop new and effective pharmacological treatments for older dysphagic patients, from compensation to recovery of swallow function.', 'detailedDescription': 'The project consists of a randomized, double-blind controlled interventional clinical trial (patient and analysis of results) with five treatment arms and a control group (placebo) involving a total of 150 elderly patients with oropharyngeal dysphagia (25 patients per group).\n\nThe recruitment of participants for the study will be carried out from the patients referred to the Dysphagia Unit of the Hospital de Mataró for the evaluation of swallowing disorders. The swallowing function of all candidates to be included in the study will be clinically evaluated using the volume-viscosity swallowing test (V-VST). Those patients with signs of impaired safety of swallowing during the examination (cough, decreased O2 saturation greater than 2% or voice change) will be candidates to participate in the study. They will be informed and in case of acceptance a saliva sample will be taken, and a videofluoroscopy (VFS) will be performed. If the patient presents impaired safety of swallow (Penetration aspiration scale higher or equal than 2), the patient will be definitively randomized to one of the branches of intervention and the rest of the explorations will proceed (sensory evoked potentials to pharyngeal electrical stimulation and pharyngeal motor evoked potentials to transcranial magnetic stimulation). After the treatment period a second evaluation of study procedures will be performed.\n\nThe treatment will consist of administering 10mL solution of the study product, according to randomization, 3 times a day (before breakfast, lunch and dinner) for 14 consecutive days after inclusion in the study. Treatment selected according our previous studies (Alvarez-Berdugo et al. Neurogastroenterol Motil 2017) are: Capsaicin 10microM, Piperine 150microM, Cinnamaldehyde 756,6microM + zinc 70microM, citric acid 457,5microM (pH=3,5), Capsaicin 10microM + citric acid 457,5microM (pH=3,5). For the control group, placebo product will be administered, which will be the vehicle solution with a more neutral pH.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['OLDER_ADULT'], 'minimumAge':
