Sham Transcutaneous Electrical Stimulation of Vagus NerveThis study aims to determine whether electrical stimulation of the ear, when combined with physical and speech therapy, can improve symptoms in subjects diagnosed with Parkinson´s disease, by comparing two different application sites. Each subject will undergo an initial in-person screening and provide consent before participating in the study. The main questions to answer are: * Does transcutaneous electrical nerve stimulation (tVNS) in the ear paired with physical and speech therapy improve speech and voice-related problems, airway protection, salivation, and swallowing? * Does tVNS paired with physical and speech therapy improve tremor, walking speed, and balance in people with PD? * Does tVNS paired with physical and speech therapy improve heart rate and heart rate variability in people with PD? * Do its effects persist at 8 weeks? Participants will: Attend 12 rehabilitation sessions over 4 weeks (three per week). During each session, participants received either active or sham tVNS, accompanied by speech therapy (once per week), physical therapy (once per week), or conducted alone (once per week). Undergo speech, voice, swallowing, respiratory, gait, balance, tremor, heart rate variability, and cognitive testing, as well as questionnaires regarding the quality of life, before and after treatment. Return for a follow-up visit eight weeks after therapy to check how long the effects last.	Parkinson	Non applicable	Traitement symptomatique	Spain	À vérifier
Sham Transcutaneous vagus nerve stimulation (Sham t-VNS)Cardiovascular disease is one of the most important causes of death and disability in the world. An autonomic imbalance is associated to cardiovascular risks and disorders. Electrical stimulation (ES) applied by surface electrodes is a non-invasive therapeutic approach with low side-effects. In the last years, some studies had investigated the effects of ES on the autonomic nervous system and cardiovascular system. However, different intensities, frequencies and electrode locations had been used, which makes difficult to clarify the optimal parameters. The aim of this study is to analyze the effects of ES on autonomic nervous modulation in healthy subjects comparing three different locations of application for ES. Participants will be aleatory assigned to one of three groups for a single-session of 20-minute transcutaneous ES: a) an auricular intermittent ES in an area that is believed to be connected to the vagal nerve (cymba conchae); b) an auricular sham intermittent ES, meaning a real ES but applied on an ear location not connected to the vagal nerve (scapha); and c) an upper back continuous ES (C7-T4), a placement that is thought to be connected to the stellate (sympathetic) ganglion. All the protocols will be stated at a non-painful intensity. After that, the hand grip exercise will be executed. The heart rate variability (HRV) and heart frequency (HR) will be measured in four main times: the baseline, in the final minutes of the ES, after the ES and after finishing the hand grip exercise. Blood pressure will be measured also at all the time points except during the ES due to the possibility of interferences. Adverse effects will be assessed after ES and 48 h later. The study will provide initial knowledge about how different electrical stimulation locations contribute to reduce sympathetic excitation and improve the sympathovagal balance.
