Normativa SEPAR sobre disfunción muscular de los pacientes con enfermedad pulmonar obstructiva crónica / Guidelines for the evaluation and treatment of muscle dysfunction in patients with chronic obstructive pulmonary disease

La disfunción muscular de pacientes con enfermedad pulmonar obstructiva crónica (EPOC) constituye una de las comorbilidades más importantes, con repercusiones negativas en su capacidad de ejercicio y calidad de vida. En la presente normativa se ha resumido la literatura publicada más recientemente sobre los diferentes aspectos del tema y se ha utilizado también la escala Grading of Recommendations Assessment, Development, and Evaluation (GRADE) de recomendaciones sobre el grado de evidencia de las diferentes propuestas de la normativa. Respecto a una población control, se estima que en un tercio de los pacientes EPOC la fuerza del cuádriceps es un 25% inferior incluso en estadios precoces de su enfermedad. Aunque tanto los músculos respiratorios como los de las extremidades están alterados, estos últimos suelen verse mayormente afectados. Diversos factores y mecanismos biológicos están involucrados en la disfunción muscular de los pacientes. Se proponen diversas pruebas para evaluar y diagnosticar el grado de afectación de los músculos respiratorios y de las extremidades (periféricos), así como identificar la capacidad de esfuerzo de los pacientes (prueba de marcha de 6 min y cicloergometría). Se describen también las posibles estrategias terapéuticas vigentes que incluyen las diversas modalidades de entrenamiento y de soporte farmacológico y nutricional

In patients with chronic obstructive pulmonary disease (COPD), skeletal muscle dysfunction is a major comorbidity that negatively impacts their exercise capacity and quality of life. In the current guidelines, the most recent literature on the various aspects of COPD muscle dysfunction has been included. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) scale has been used to make evidence-based recommendations on the different features. Compared to a control population, one third of COPD patients exhibited a 25% decline in quadriceps muscle strength, even at early stages of their disease. Although both respiratory and limb muscles are altered, the latter are usually more severely affected. Numerous factors and biological mechanisms are involved in the etiology of COPD muscle dysfunction. Several tests are proposed in order to diagnose and evaluate the degree of muscle dysfunction of both respiratory and limb muscles (peripheral), as well as to identify the patients’ exercise capacity (six-minute walking test and cycloergometry). Currently available therapeutic strategies including the different training modalities and pharmacological and nutritional support are also described

Rehabilitación respiratoria / Pulmonary Rehabilitation

La rehabilitación respiratoria (RR) ha demostrado mejorar la disnea, la capacidad de esfuerzo y la calidad de vida relacionada con la salud en los pacientes con enfermedad pulmonar obstructiva crónica (EPOC). En otras enfermedades distintas de la EPOC también ha mostrado beneficios, aunque el grado de evidencia es menor. Los componentes fundamentales de los programas de RR son el entrenamiento muscular, la educación y la fisioterapia respiratoria, siendo aconsejable también contemplar la terapia ocupacional, el soporte psicosocial y la intervención nutricional. Los programas domiciliarios han demostrado igual eficacia que los hospitalarios. La duración de los programas de RR no debe ser inferior a 8 semanas o 20 sesiones. La RR iniciada precozmente, incluso durante las exacerbaciones, ha demostrado ser eficaz y segura. La utilización de oxígeno o ventilación no invasiva durante el entrenamiento es controvertida y dependiente de la situación del paciente. En el momento actual desconocemos cuál es la mejor estrategia para mantener los beneficios de la RR a largo plazo. Una mayor duración de los programas o la telemedicina podrían ser claves para prolongar los resultados conseguidos

Pulmonary rehabilitation (PR) has been shown to improve dyspnea, exercise capacity and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD). PR has also shown benefits in diseases other than COPD but the level of evidence is lower. The fundamental components of PR programs are muscle training, education and chest physiotherapy. Occupational therapy, psychosocial support and nutritional intervention should also be considered. Home programs have been shown to be as effective as hospital therapy. The duration of rehabilitation programs should not be less than 8 weeks or 20 sessions. Early initiation of PR, even during exacerbations, has proven safe and effective. The use of oxygen or noninvasive ventilation during training is controversial and dependent on the patient's situation. At present, the best strategy for maintaining the benefits of PR in the long term is unknown. Longer PR programs or telemedicine could play a key role in extending the results obtained
