Neuromuscular Electrical Stimulation with Russian Current for Expiratory Muscle Training in Patients with Chronic Obstructive Pulmonary Disease

Abstract

Abstract.[Purpose] To analyze the effects of neuromuscular electrical stimulation (NMES) applied to the abdominal muscles of patients with COPD.[Subjects] A total of 22 patients in group A, mean age of 68.2 ± 6.4 years and in group B, 71.2 ± 10.1 years.[Methods] Randomized clinical trial. Patients with COPD were randomly an evenly divided into two groups: group A (NMES + conventional therapy) and group B (conventional physiotherapy) and respiratory muscle strength was measured by pressure manometry before and after the end of the experimental protocols.[Results] Maximum inspiratory pressure before and after the intervention of group A was −64 (44-74) cm H2O, respectively, and −68 (56-96) cmH2O, and in group B, −52 (46-92) cm H2O and −60 (50-72) cmH2O. Maximum expiratory pressure of group A was 84 (72-92) cmH2O and 112 (94-120), respectively, and in group B, 76 (60-100) cmH2O and 84 (60-108) cmH2O.[Conclusion] The results indicate that expiratory muscle training with Russian current together with conventional physical therapy during hospitalization improves the respiratory muscle strength of patients with COPD.

Effectiveness of neuromuscular electrical stimulation for the rehabilitation of moderate-to-severe COPD: a meta-analysis

“…Of 25 full-text citations, nine studies with 276 participants fulfilled inclusive criteria to be reviewed. For papers excluded from this analysis, eight were due to study design,10,13,15,16,40–43 four were due to the fact that stimulation was acupuncture,44–47 three11,24,28 had insufficient or inapplicable data, and one25 reported on the same group of participants as in another paper 26Figure 1 describes the different phase of the search process.…”

“…Previous studies11–20 have not reached consistent conclusions, and a meta-analysis21 published in 2014 draw equivocal findings on the effects of NMES in moderate-to-severe COPD. Also, there have been several larger-scale and higher-quality trials22–28 published in recent years; therefore, we performed a meta-analysis to investigate the effects of NMES in these patients.…”

Inspiratory Plus Expiratory Neuromuscular Electrical Stimulation Versus Diaphragm Pacing for Rehabilitation in Severe COPD Patients: A Randomized Controlled Trial

“…At present, respiratory muscle electrical stimulation To some extent replace muscle training pulmonary rehabilitation for some particular COPD patients, which can improve the patient's respiratory muscle endurance and strength [9]. A systematic retrospective study on respiratory muscle training recommends that each training time lasts 20-30 minutes [17].…”

“…Historically, transcutaneous electrical diaphragmatic stimulation, a form of inspiratory neuromuscular electrical stimulation, has been shown to increase respiratory minute volume in patients with COPD [8]. Studies have con rmed that abdominal electrical stimulation can improve ventilation parameters such as peak expiratory ow rate in patients with COPD [9]. However, until now, there have been no studies on evaluation of the inspiratory plus expiratory neuromuscular (diaphragmatic and abdominal muscles) electrical stimulation for COPD individuals.…”
