“…Clinical benefits of NMES have been demonstrated in patient populations other than COPD with a broad range of frequencies and session durations ranging from as few as 10-15 muscle contractions?day -1 up to 8-12 h continuous NMES has been used among patients with severe exercise limitation due to congestive heart failure (CHF), with skeletal muscle dysfunction similar to that found in COPD. NMES delivered to the quadriceps and calf muscles for 1 h?session -1 , 5 days?week -1 and 5 weeks at a frequency of 10 Hz and the maximal tolerated amplitude, without any additional exercise training, led to significant improvements in muscle mass, exercise tolerance and delay in reaching the anaerobic threshold [37]. 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].…”

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.

“…We demonstrated that LFES can effectively counterbalance their decreased physical capacity. The LFES protocol selected (frequency 10 Hz, stimulation 1 h/day, 7 days/week for 8 weeks) was very similar to that used by Maillefert, et al 21) who first reported a significant improvement of exercise capacity parameters in 14 patients with CHF after 5 weeks of LFES, namely an improvement of VO 2peak , VO 2AT , and a 6 minute walking test. In the same study, a nuclear magnetic resonance test showed a significant increase in the muscle mass of the triceps surae muscle.…”

Electrical Stimulation of Skeletal Muscles An Alternative to Aerobic Exercise Training in Patients With Chronic Heart Failure?

et al. 2006

SUMMARYThe aim of this study was to investigate whether electrical stimulation of skeletal muscles could represent a rehabilitation alternative for patients with chronic heart failure (CHF). Thirty patients with CHF and NYHA class II-III were randomly assigned to a rehabilitation program using either electrical stimulation of skeletal muscles or bicycle training. Patients in the first group (n = 15) had 8 weeks of home-based low-frequency electrical stimulation (LFES) applied simultaneously to the quadriceps and calf muscles of both legs (1 h/day for 7 days/week); patients in the second group (n = 15) underwent 8 weeks of 40 minute aerobic exercise (3 times a week). After the 8-week period significant increases in several functional parameters were observed in both groups: maximal VO 2 uptake (LFES group: from 17.5 ± 4.4 mL/kg/min to 18.3 ± 4.2 mL/kg/min, P < 0.05; bicycle group: from 18.1 ± 3.9 mL/kg/min to 19.3 ± 4.1 mL/kg/min, P < 0.01), maximal workload (LFES group: from 84.3 ± 15.2 W to 95.9 ± 9.8 W, P < 0.05; bicycle group: from 91.2 ± 13.4 W to 112.9 ± 10.8 W, P < 0.01), distance walked in 6 minutes (LFES group: from 398 ± 105 m to 435 ± 112 m, P < 0.05; bicycle group: from 425 ± 118 m to 483 ± 120 m, P < 0.03), and exercise duration (LFES group: from 488 ± 45 seconds to 568 ± 120 seconds, P < 0.05; bicycle group: from 510 ± 90 seconds to 611 ± 112 seconds, P < 0.03). These results demonstrate that an improvement of exercise capacities can be achieved either by classical exercise training or by home-based electrical stimulation. LFES should be considered as a valuable alternative to classical exercise training in patients with CHF. (Int Heart J 2006; 47: 441-453)

“…40 The fact that we did not find significant difference in relation to trophism, besides the application of NMES being consistently considered related to an increase in body mass, 41 it can be explained by the subjectivity of this measurement method to determine the muscular circumference when different muscle tensions is applied to the tape measure during the evaluation as well as the small number of subjects in the sample.…”

Muscle training program in patients with severe chronic obstructive pulmonary disease

Objective: The objective of this study was to analyze the effects of a muscle training program with neuromuscular electrical stimulation (NMES) for lower limbs (LL) and active resisted exercises for upper limbs (UL) for patients with severe Chronic Obstructive Pulmonary Disease. Methods: With a sample of 5 subjects (65.2 ± 6.09 years), the initial and final evaluations were: One-RepetitionMaximum testing; Sit-to-stand test; perimetry of the thigh; 6-minute walk test; Saint George's Respiratory Questionnaire; Medical Research Council scale for dyspnea and the BODE index. The intervention was performed three times a week and was composed of 18 sessions of 30-minute NMES followed by 30 minutes of exercise for the UL based on the diagonal Kabat method. The NMES parameters were: 50Hz of frequency, 6s on and 8s off, increase slope of 2s and decrease slope of 2s, pulse width of 400µs, and intensity defined as patient tolerance and increased from 1 to 5mA each day. Results: The results have shown an increase in muscle strength (p = 0.01) and of muscle resistance (p = 0.01). There was an improvement tendency in the quality of life (p = 0.16) and in the cardiorespiratory fitness (p = 0.11). Conclusion: The association of physical exercises with diagonals and NMES can be a beneficial resource for the treatment of patients with severe COPD. It is suggested, however, the need for new researches with a wider sample size for assuring these benefits.
