Skeletal muscle dysfunction impairs exercise capacity, quality of life and prognosis in chronic obstructive pulmonary disease (COPD). The purpose of this prospective randomized controlled study was to evaluate effects of Neuromuscular electrical stimulation (NMES) plus quadriceps muscle training (NMES group) and sham NMES plus quadriceps muscle training (control group) on muscle function, exercise capacity, health related quality of life, activities of daily living, and self-efficacy in patients with COPD who are eligible and able to participate in endurance training.
Skeletal muscle dysfunction is common and impaires exercise capacity in patients with chronic obstructive pulmonary disease (COPD)Exercise training is the main component of the treatment of COPD.
Neuromuscular electrical stimulation (NMES) is successful in COPD patients who are unable to perform exercise training. The NMES has positive effect on peripheral muscle function, exercise capacity and breathlessness in activities of daily living in COPD patients who had an abnormal body composition or who were too dyspneic to leave their home. A nonrandomized uncontrolled study has shown that application of NMES at home for improved exercise capacity in patients with better-preserved muscle mass. Evidence from a preliminary study without applying sham NMES revealed that NMES applied as complementary to ambulatory respiratory rehabilitation program increased quadriceps strength, quality of life and six minute walk distance in severe to very severe patients.
Despite documented benefits of NMES in COPD patients, the place of NMES as an adjunct to pulmonary rehabilitation in COPD patients who were able to do regular endurance and strength training on is unknown. Therefore, the purpose of this study was to compare the effects of NMES plus quadriceps muscle training (NMES group) and sham NMES plus quadriceps muscle training (control group) on muscle function, dyspnea, fatigue, exercise capacity, health related quality of life, activities of daily living, and self-efficacy in patients with COPD who are eligible and able to participate in endurance training.

| Neuromuscular electrical stimulation | Other | Bilateral quadriceps NMES using a four-channel portable electrical stimulator. Biphasic symmetric constant current impulses with a pulse width 300 µs, a frequency of 50 Hz, and duty cycle of 10 s on and 20 s off was applied for 20 min per day, 2 days per week for 10 weeks. |
| Measure | Description | Time Frame |
|---|---|---|
| Incremental shuttle walk test | The incremental shuttle walk test was performed in an enclosed corridor. Patients were required to walk back and forth, turning around two cones placed 9 meters apart making the shuttle distance 10 meters long. Patients followed the rhythm dictated by the audio signal. | 10 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Endurance shuttle walk test | An endurance shuttle walk test was used to measure endurance walking capacity. The endurance shuttle walk test was performed 85% of peak oxygen consumption as predicted from the incremental shuttle walk test. | 10 weeks |
