BACKGROUND: Neuromuscular electrostimulation has become a promising issue in cardiovascular rehabilitation. However there are few articles published in the literature regarding neuromuscular electrostimulation in patients with heart failure during hospital stay. METHODS: This is a randomized controlled pilot trial that aimed to investigate the effect of neuromuscular electrostimulation in the walked distance by the six-minute walking test in 30 patients admitted to ward for heart failure treatment in a tertiary cardiology hospital. Patients in the intervention group performed a conventional rehabilitation and neuromuscular electrostimulation. Patients underwent 60 minutes of electrostimulation (wave frequency was 20 Hz, pulse duration of 20 us) two times a day for consecutive days until hospital discharge. RESULTS: The walked distance in the six-minute walking test improved 75% in the electrostimulation group (from 379.7 +/- 43.5 to 372.9 +/- 46.9 meters to controls and from 372.9 +/- 62.4 to 500 +/- 68 meters to electrostimulation, p < 0.001). On the other hand, the walked distance in the control group did not change. CONCLUSION: The neuromuscular electrostimulation group showed greater improvement in the walked distance in the six-minute walking test in patients admitted to ward for compensation of heart failure.
