Neuromuscular Adaptations to Low-Frequency Stimulation Training in a Patient with Chronic Heart Failure
Electrical myostimulation (EMS) has recently been proposed as an interesting rehabilitation tool in patients with chronic heart failure (CHF). Although its beneficial effects on exercise capacity and muscle strength have been demonstrated, the neuromuscular adaptations responsible for improved performance are not well understood. This preliminary case report was therefore planned to investigate the neural and muscular adaptations to a 5-wk EMS program in one patient. An increase in maximal strength (10.5%) was accompanied by increased twitch torque (13.9%) and slowing of muscle contractile properties (half-relaxation time, time to peak torque, and maximal rate of relaxation increased by 7.1…
Rehabilitación en la arteriopatía de los miembros inferiores
La rehabilitacion en la arteriopatia de los miembros inferiores se basa en programas personalizados que asocian readaptacion al esfuerzo y educacion terapeutica. Aumenta las capacidades fisicas, sobre todo la distancia de la marcha, permite reanudar las actividades, reduce los factores de riesgo y mejora los frecuentes trastornos del estado de animo que se observan en estos pacientes. Mejora las anomalias fisiopatologicas, en especial el desequilibrio neurovegetativo y la disfuncion endotelial. Se recomienda un programa ambulatorio de al menos tres sesiones por semana durante 2-3 meses. La evaluacion funcional (pruebas de esfuerzo maximo, pruebas de marcha) permite adaptar el programa de re…
Reproducibility, validity and responsiveness of the 200-metre fast walk test in patients undergoing cardiac rehabilitation
Objective: To investigate the reliability, validity and responsiveness of the 200-metre fast walk test in patients with coronary artery disease engaged in a cardiac rehabilitation programme. Design: Descriptive study. Setting: Tertiary care hospital. Subjects: Thirty stable patients with coronary artery disease (51.9 ± 8.7 years), referred to the cardiac rehabilitation department after an acute coronary syndrome. Intervention: Not applicable. Main measures: Six-minute walk test distance, time to perform the 200-m fast walk test, peak power output of the graded maximal exercise test, before and after the programme; SF-36 quality of life questionnaire at baseline. Walk tests were performed tw…
Effects of an eccentric training personalized by a low rate of perceived exertion on the maximal capacities in chronic heart failure: a randomized controlled trial
International audience; BACKGROUND: The eccentric (ECC) training, in spite of its potential interest (slightest request of the cardiorespiratory system) compared with the concentric (CON) training, is not applied during the rehabilitation of the chronic heart failure (CHF). The main reasons are the difficulty personalizing the ECC exercises by avoiding the muscle complications and the lack of information concerning the specific effects on the maximal capacities in CHF patients.AIM: To compare — following a prior study on the feasibility and on the functional impacts — the effects on maximal capacities and tolerance in CHF of ECC training tailored by a low rate of perceived exertion (RPE) an…
Comparison of low-frequency electrical myostimulation and conventional aerobic exercise training in patients with chronic heart failure.
Physical training is recommended as an efficient therapy in patients with chronic heart failure (CHF). Low-frequency electrical myostimulation (EMS) has recently been suggested as a good alternative to conventional aerobic training. The aim of this study was to compare the effects of EMS and conventional exercise training in patients with moderate to severe CHF.Twenty-four patients with stable CHF (56.7+/-7.3 years, New York Heart Association grades II and III) underwent 5 weeks of exercise training, 5 h a week, using EMS (n=12) or conventional (n=12) training programmes. At baseline and after the training period, patients performed a symptom-limited cardiopulmonary test, a 6-min and a 200-…
Is the Short and Fast Step Test a safe and feasible tool for exploring anaerobic capacities of individuals with coronary heart disease in clinical practice?
Background While its importance in daily living, the anaerobic metabolism is not taken into account in clinical practice. The lack of validated functional performance tests for patients with chronic disabilities may explain this defect. In this context, the Short and Fast Step Test (SFST) was recently developed and validated in healthy volunteers. Aim The purpose of this study was to investigate the safety, feasibility and reliability of the SFST, a functional test exploring anaerobic metabolism in coronary patients during cardiac rehabilitation. Design This study was a monocentric prospective study. Settings This study took place in the rehabilitation center of the University Hospital Cent…
