Biofeedback Cardiovascular y sus Aplicaciones: revisión de literatura

El biofeedback cardiovascular es una técnica de automodulación fisiológica mediada por la resonancia entre dos mecanismos de regulación cardiovascular: el reflejo barorreceptor y la arritmia sinusal respiratoria. Cuando ese fenómeno ocurre, es posible visualizar un aumento significativo en la amplitud de la frecuencia en torno a 0.1Hz, llamada baja frecuencia (low frequency, LF). En ese trabajo, se consultó la base de datos Pubmed y fueron revisados 31 trabajos, publicados entre el 2000 y junio del 2012. El protocolo más utilizado (en 43.94% de los artículos) fue desarrollado por Lehrer, Vaschillo, & Vaschillo (2000), y involucra 10 sesiones semanales, de 20 minutos cada una, y entrenamiento doméstico diario, dos veces al día durante 20 minutos. El entrenamiento con biofeedback ha presentado resultados promisorios como terapia complementar en diferentes trastornos, con reducción significativa en las escalas de ansiedad y depresión, sea cuando esas patologías se presentan como única molestia o como comorbilidad en otros trastornos. Los efectos sobre alteraciones cognitivas presentan resultados inconsistentes.

Effects of pulmonary rehabilitation program in a patient with severe asthma diagnosis

Objective: to present the effectiveness of pulmonary rehabilitation programs in the treatmentof a patient with asthma, this is the case of a young Caucasian girl —17 years old— with severe asthma diagnosis, with symptoms since she was eight years old, 10th grade student. Method: She was referred to the program of Pulmonary Rehabilitation after three hospitalizations during the last year due to asthmatic crises, dyspnoea in activities of daily living, and intolerance to physical exercise. In the initial evaluation, a patient with non-controlled asthma was found; she was receiving short-acting medication admitting that she was not complying with regular use and with a prescribed dose of the pharmacological treatment and that she ignored the importance of this commitment for optimal evolution. The patient expressed concern about the progressive deterioration at her respiratory and functional level during the last year and her fear and anxiety for not being able to breathe during activities befitting her age. Results: One month after receiving bronchodilators and long-acting steroids permanently and complying with recommendations about regular use and adequate inhalatory technique, the patient was included in a three-times a-week program of pulmonary rehabilitation during eight weeks for upper and lower extremity endurance and resistance training. Conclusion: This intervention showed significant changes in the patient at functional level and a greater social participation.

Implementation of ‘School Back’ by the ‘Core’ technique in a factory of geotextiles to prevent back pain

Introduction: This article aims to show an alternative intervention for the prevention and control of back pain to the people of a production plant of geotextiles for the construction exposed to handling and awkward postures through the implementation of the Back School using the CORE technique. This technique being understood as trainer of the stability musculature of the spine; whose benefit is proportionate the muscular complex of the back, stability and avoid osteomuscular lesions and improved posture. Objective: To present the results about the implementation of the back school by the CORE technique for prevention of back pain in a population of forty-eight male collaborators. Materials and methods: The back school began with talks of awareness by the occupational health physician explaining the objectives and benefits of it to all participants. Once this activity was done, was continued to evaluate all plant employees to establish health status through the PAR-Q questionnaire, who were surveyed for the perception of pain using visual analog scale (VAS) and stability was determined column through the CORE assessment, to determine the training plan. Then, were made every six months the revaluations and implementation of a survey of assistant public perception to identify the impact of the implementation of the school back on the two variables referred (pain perception and stability of column). Results: The pain perception according VAS increased in the number of workers asymptomatic in 12% and based in the satisfaction survey 94% of population reported that with the development of this technique decrease the muscle fatigue in lumbar level; and 96% of population reported an improvement in the performance of their work activities. Discussion: Posterior to the analysis of all results, it is interpreted that back schools practice through CORE technique, contributes to the prevention and / or control of symptoms at the lumbar level in population of productive sector exposed to risks derived from the physical load, provided that ensure its continuously development and supervised for a competent professional.
