[en] Introduction. Parkinson's disease is the second degenerative disease in Spain, after Alzheimer's disease, with important repercussions on the patient, his/her family environment and at a health level. Its main symptoms are: tremor, rigidity, bradykinesia and postural instability. There are also other less frequent symptoms such as speech, urinary, sexual, olfactory, digestive and breathing disorders among others, but which are not less important, taking into account that, concerning breathing disorders, pneumonia is one of the first causes of death among patients with Parkinson's disease (PD), and its prevention is essential in order to improve the patients' quality of life, reduce hospital admissions as well as lower healthcare expenditure. Chest physiotherapy is a relevant and efficient treatment, since it prevents respiratory infections and/or treats them if there are already previous infections. There is no consensus on the breathing pattern that patients with Parkinson's disease (PD) show and there are no intervention protocols that deal with the current breathing disorders and that can guide healthcare professionals in their treatment. Due to the lack of scientific evidence it is necessary to increase the studies that prove the efficacy of chest physiotherapy with effective and reasonable protocols. Objective. The principal objective is to study the efficacy of chest physiotherapy for the treatment of thoracic-pulmonary disorders of patients with Parkinson's disease. Methodology. A single-blind, randomised, controlled clinical trial will be undertaken in a public hospital in Ferrol area. The subjects will participate in an intervention program of chest physiotherapy which will last two months, four days a week, and each session will be forty-five minutes long. The treatment is divided in five exercises (diaphragmatic breathing, global costal expansions, prolonged slow expiratory (PSE) technique, exercises with an incentive spirometer and directed or manual coughing). The control group will not interfere in any way. It will conduct the assessments and explorations before and after the treatment period of the experimental group. By means of different respiratory assessments and explorations which will be performed before and after the treatment, the effectiveness of chest physiotherapy will be evaluated and an analysis of whether there have been significant changes in them or not will be made.

[gl] Introdución A enfermidade de Parkinson é a segunda enfermidade neurodexenerativa en España, despois da enfermidade de Alzheimer, con importantes repercusións no enfermo, no seu entorno e a nivel sanitario. Os seus principais síntomas son:O tremor, a rixidez, a bradicinesia e a inestabilidade postural. Ademais, existen outros síntomas menos frecuentes, como son os trastornos da fala, urinarios, sexuais, olfativos, dixestios, respiratorios, entre outros, non menos importantes, tendo en conta que nos trastornos respiratorios a neumonía é unha das principais causas de morte en a enfermidade de Parkinson, sendo a súa prevención primordial para mellorar a calidade de vida do enfermo, diminuír os ingresos hospitalarios como tamén reducir o gasto sanitario. A fisioterapia respiratoria é un tratamento eficaz e relevante, xa que prevén as infeccións respiratorias e / ou trata no caso de que xa existan estas infeccións. Non hai un consenso sobre o patrón respiratorio que presente el EP nin hai protocolos de intervención. Debido á falta de evidencia científica é necesario aumentar os estudios que demostren a eficacia da fisioterapia respiratoria con protocolos efectivos e asequibles. Obxectivo. Como obxectivo principal búscase estudar a eficacia da fisioterapia respiratoria nas alteración toraco-pulmonares no enfermo do Parkinson. Metodoloxía. Realizárase un ensaio clínico controlado e aleatorizado a simple cego, nun centro hospitalario público da comarca de Ferrol. Os suxetos formarán parte dun programa de intervención da fisioterapia respiratoria que durará un periodo de dous meses, 4 días á semana, cada sesión terá unha duración de 45 minutos. O tratamiento divídese en 5 exercicios (respiración diafragmática, expansións costales globais, aumento do fluxo espiratorio lento (AFEL), exercicios con espirómetro incentivador e tos asistida ou manual. O grupo control non terá ningún tipo de intervención. Realizará as valoracións e exploracións antes e despois do período do tratamento do grupo experimental. A través de diferentes valoracións ou exploracións respiratorias que faranse antes e despois do tratamento, evaluarase a eficacia da fisioterapia respiratoria e se analizará se tivese ou non cambios significativos nos mesmos.
