Neuromuscular electrical stimulation improves clinical and physiological function in COPD patients

Summary Background Neuromuscular electrical stimulation (NMES) improves muscle performance and exercise tolerance in chronic obstructive pulmonary disease (COPD) patients. In contrast, no study has assessed the effect of NMES on dynamic hyperinflation (DH) in COPD. This study investigated the effect...

Description
Summary:Summary Background Neuromuscular electrical stimulation (NMES) improves muscle performance and exercise tolerance in chronic obstructive pulmonary disease (COPD) patients. In contrast, no study has assessed the effect of NMES on dynamic hyperinflation (DH) in COPD. This study investigated the effect of short-term, high-frequency NMES on DH in patients with COPD. Methods Twenty patients were randomly allocated to either a NMES applied bilaterally to the quadriceps muscles ( n  = 11: 8 weeks, 5 days/week, twice/day, 45 min/session) or a control group ( n  = 09). All patients received respiratory physical therapy and stretching exercises. Free fat mass, pulmonary function, time to exercise tolerance (T lim ), 6-min walk test distance (6-MWTD), tumor necrosis factor (TNF-α) and β-endorphin levels, Borg dyspnea and leg score (BDS and BLS) and quality of life by the St. George's Respiratory Questionnaire score (SGRQ) were examined before and after the intervention. Results Compared with the control group, NMES increased FEV1 and FEV1 /FVC, 6-MWD and T lim ( P
