简要总结
Background: Patients with COPD often experience skeletal muscle dysfunction. For those who are unable or unwilling to undertake physical training, neuromuscular electrical stimulation (NMES) may provide an alternative method of exercise training.
Objective: To investigate the effects of adding neuromuscular electrical stimulation of gluteus maximus, quadriceps and calf muscles to chest physiotherapy, compared to chest physiotherapy alone, on muscles strength (gluteus max., quadriceps, calf muscles), femoral blood flow physical and pulmonary function in severe COPD Patients.
详细描述
Material and methods
This study include a group of 60 patients (30 males and 30 females) diagnosed with severe COPD), their age is ranged 65-75 years, they will be randomly divided into two groups; study group (A) 30 patients and study group (B) 30 patients. Study group (A): The patients in this group will receive the chest physiotherapy program for 20 min each day, for five days a week for three consecutive weeks. Study group (B): The patients in this group will receive the same chest physiotherapy program combined with neuromuscular electrical stimulation of gluteus max., quadriceps, calf muscles, performed for 30 min /day for five days a week for three consecutive weeks. Femoral blood Flow, gluteus maximus, quadriceps and calf muscles strength and pulmonary function (FEV1/FVC) will be measured for both groups pre and post treatment.

结局指标
主要结局
Muscle strength measurement
时间窗: change from baseline to 3 weeks after intervention and 3 days as a follow-up
To determine the maximal muscle strength the Lafayette manual muscle test system (USER MANUAL) (MMT) Model 01163, White Plains, New York (10602) of gluteus maximus, quadriceps and calf muscles will be measured on right lower limb.
Six-minute walking test (Physical function assessment
时间窗: change from baseline to 3 weeks after intervention and 3 days as a follow-up
The six-minute walking distance (6MWD) was measured according to a standardized protocol. * Subjects were instructed to walk at their own pace along a 34.5-m corridor from one end to the other, covering as much ground as possible in the allotted time. * Subjects were allowed to stop and rest during the test, but they were instructed to resume walking as soon as they felt able to do
Pulmonary function test
时间窗: change from baseline to 3 weeks after intervention and 3 days as a follow-up
Pulmonary capacity and respiratory muscle functions will be assessed using the CPFS/D USB™ 187 Spirometer (Medical Graphics-MGC, St. Paul, MN, USA) with airflow being measured by a 188 calibrated Pitot tube (PreVent, Pneumotach). The participant completed at least three acceptable maximal forced and slow expiratory maneuvers after 15 min the inhalation of 400 mg of salbutamol 190 via a metered-dose inhaler. Forced vital capacity (FVC, L), forced expiratory volume in one second (FEV1, L), FEV1/ FVC, and inspiratory capacity (IC) will be measured according to American Thoracic Society standards
次要结局
- Blood flow velocimetry measurement(change from baseline to 3 weeks after intervention and 3 days as a follow-up)
