    Acupuncture-like transcutaneous electrical nerve stimulation as an accelerating tool for the recovery of the tissues exposed to vocal overload
    (Universidad de Castilla la Mancha, 2020) Fuentes Aracena, C.; Arrau Bordali, J.; Pino Quiroz, G.; Valdivia Alarcón, N.; Aguilar Pavez, C.
    Traditionally, it has been suggested that rest is the ideal tool to allow natural recovery of tissues induced by overload. However, the times necessary for this to occur are very long. It has been estimated that electrotherapy is useful when it comes to recover some overused tissues, however, these benefits in vocal function are unknown. The purpose of this study was to describe the effects of acupuncture-like transcutaneous electrical nerve stimulation on the laryngeal and cordai tissues that were previously subjected to vocal overload. In this research. 21 women without pathology or vocal training participated, whose age was 24 ± 1.28 years. The participants were subjected to vocal overload for 40 minutes and subsequently to 15 minutes of acupuncture-like transcutaneous electrical nerve stimulation. Through continuous laryngoscopy, acoustic-perceptual analysis and symptomatic study, the changes caused by electrotherapy were examined. The main results include perilaryngeal and intrinsic laryngeal muscles relaxation, and elimination of the symptoms suffered. This way it is concluded that electrostimulation is a useful tool in the acceleration of tissue recovery subjected to vocal overload.

    Role of physical agents in vocal rehabilitation: A literature review
    (Universidad de Castilla la Mancha, 2020) Fuentes Aracena, C.
    Physical agents are natural or artificial elements that are applied for the treatment of certain symptoms or pathologies. In vocal rehabilitation, the study of physical agents is an emerging area, where systematic reviews and meta-analyzes are scarce. This, many times, hampers the decision making and the correct choice by the clinician. The objective of this study was to analyze the role of physical agents in vocal rehabilitation. A literature review was conducted through the search for papers in the databases PubMed, EBSCOHost and Scielo. Eligibility criteria were established according to type, year and characteristics of the studies. Six hundred and three (603) papers were assessed, of which, following the analysis of their titles, abstracts and compliance with the eligibility criteria, 16 were selected. Results were delivered based on the number of participants, level of evidence, type and setup of the physical agent, evaluation procedures and instruments and benefits obtained. The most frequently used physical agents in the vocal clinic are electrotherapy (TEN'S and NMES) and laser therapy. In general, they act as adjuvants in vocal therapy. TENS reduces pain, laryngeal tension and tight voice perception during phonation. NMES benefits the neuromuscular activation of vocal cords, and the laser use allows for the recovery of laryngeal tissues after vocal overloading tasks.
