“…This was the first study to demonstrate that skeletal muscle electrical stimulation regimens can attenuate the production of cardiovascular inflammatory mediators and exert beneficial effects on endothelial dysfunction in patients with heart failure. However, in accordance with the studies of Harris et al [98] and Nuhr et al [99] and unlike the studies by Maillefert et al [94], Vaquero et al [95] Deley et al [100] and Dobsȃk et al [102], the investigators reported no significant differences in peak oxygen consumption after the completion of the protocol.…”

“…A more recent study by Deley et al [100] compared the effects of low-frequency electrical stimulation and conventional exercise training in 24 patients with stable CHF and NYHA grades II and III. The patients underwent 5 weeks of exercise training, 5 h per week, using FES (a low-frequency 10-Hz biphasic current delivered to both quadriceps and clf muscles) or conventional training programs (three 20-min periods of different aerobic exercises, i.e., treadmill, bicycle, arm cycling, with a global warm-up and cool-down).…”

Functional electrical stimulation of lower limbs in patients with chronic heart failure

Physical training is an important component of therapy for patients with chronic heart failure (CHF) and is considered complementary to their pharmacological treatment. The majority of conventional rehabilitation programs include aerobic training, which has been demonstrated to induce significant beneficial effects on the neurohumoral, immunoreactive and functional status of patients with moderate CHF. Functional electrical stimulation (FES) of skeletal muscles constitutes an alternative training mode with beneficial effects comparable to classical aerobic exercise, suitable for patients with CHF who cannot participate in traditional training programs due to either advanced grades of CHF or the presence of comorbidities. We present a review of the numerous studies evaluating the effects of FES in CHF, focusing on its main effects on skeletal myopathy reversal, exercise tolerance improvement and quality of life modification.

“…Muscle strength, assessed by isometric and isokinetic dynamometry, increased significantly in all subjects, which concords completely with similar clinical reports, highlighting the positive effects of chronic LFES against skeletal muscle atrophy and in enhancing muscle power in these patients. [29][30][31] In the present study, the increase in maximal muscle strength was achieved with a frequency of 10 Hz, although Quittan et al 30,31 reported an increase in muscle strength using a frequency of 50 Hz.…”

hronic congestive heart failure (CHF) is a complex metabolic syndrome resulting from global hypoperfusion and neurohumoral activation. Sympathoadrenergic hyperactivity and stimulation of the reninangiotensin -aldosterone cascade promote endothelial dysfunction in the macro-and microcirculation, and thus influence the distribution of the terminal blood flow. The increased total peripheral resistance, reduction of blood supply and impaired peripheral vascular dilatation in response to vasodilator stimuli result in atrophy of skeletal muscle and decreased oxidative activity. Physical training could reverse the pathologic changes in patients with CHF and there have been many reports during the past decade that clearly demonstrate the benefits of exercise on functional capacity, ventilation, metabolic status, autonomic control of heart rate (HR) variability and other parameCirculation Journal Vol. 70, January 2006 ters, 1-5 including skeletal muscle performance and impaired endothelial function. 6,7 However, most of the actual training protocols are based on systemic exercise requiring increased cardiac output, which cannot be achieved by all patients, and in general are only suitable for patients with a moderately advanced grade of CHF; less attention has been paid to the development of safe and efficient training programs for patients with severe grades of the disease. Background This study was designed to evaluate the effects of low-frequency electrical stimulation (LFES) on muscle strength and blood flow in patients with advanced chronic heart failure (CHF). Methods and ResultsPatients with CHF (n=15; age 56.5±5.2 years; New York Heart Association III -IV; ejection fraction 18.7±3.3%) were examined before and after 6 weeks of LFES (10 Hz) of the quadriceps and calf muscles of both legs (1 h/day, 7 days/week). Dynamometry was performed weekly to determine maximal muscle strength (Fmax; N) and isokinetic peak torque (PTmax; Nm); blood flow velocity (BFV) was measured at baseline and after 6 weeks of LFES using pulsed-wave Doppler velocimetry of the right femoral artery.

“…NMES delivered at a frequency of 50 Hz and an amplitude chosen to induce muscle contractions at 25-30% of maximal voluntary contraction induced significant increases in the strength and cross-sectional area of the thigh muscles in CHF patients awaiting heart transplantation [38]. Subsequently, additional studies have confirmed the benefits of NMES in CHF patients [39,40].…”

Evidence-based guidelines for chronic obstructive pulmonary disease (COPD) have recently been developed.Nonpharmacological treatments have evolved rapidly as an essential part of COPD therapy. They are especially important as complementary interventions in severe or very severe disease, when there is loss in function, a reduction in quality of life and when psychological impairments further complicate the disease.The present article discusses the most used nonpharmacological treatments for severe COPD patients (rehabilitation, long-term oxygen therapy, surgery, noninvasive positive pressure ventilation and supportive nutrition) and their evidence-based usefulness in promoting strategies that relieve symptoms.All of these interventions are used during end-stage disease, to promote self-efficacy, relieve symptoms and prevent further deterioration. These therapeutic options support physicians and allied professionals in improving symptom management for their patients.
