Brief summary
The aim of the randomized controlled study is to investigate the effects of NMES superimposed on voluntary contraction combined with patient education and exercise training program in patients with chronic obstructive pulmonary disease.
Detailed description
When initial assessments will be completed, patients will be assigned to one of two possible sequences by simple randomization: Superimposed NMES group (SG) or control group (CG). All volunteers will receive an COPD patient education program for once and conventional physiotherapy exercise program for COPD with the duration of 8 weeks. Additionally, superimposed NMES will be applied on quadriceps muscle of both limbs at the same time with voluntarily contraction of quadriceps muscle in SG. All patients will be assessed in terms of functional capacity, pulmonary functions, quadriceps muscle endurance and strength, dyspnea, respiratory muscle strength and quality of life at the baseline and at the end of study. Data will be collected from all the patients at baseline and at the end of study (8 weeks) by the same physiotherapist who also will supervise the exercise sessions.
Interventions
OTHERSuperimposed Neuromuscular Electrical Stimulation
NMES will be applied during each strengthening exercise session. A dual channel NMES stimulation device will be used with biphasic symmetric constant current impulses with a pulse width 300ms, a frequency of 50 Hz and a duty cycle of 10s on and 20s off protocol for 3 days a week for eight weeks.
Quadriceps strength training will be done with resistive elastics bands for 3 days a week for eight weeks.
BEHAVIORALPatient Education Program
The aim of patient education is to increase awareness of patients about COPD and develop skills to better manage their disease. The patient education will be performed at least once via face to face interview. Education topics will be covered basic information about COPD, environmental risk factors, monitoring and managing the signs and symptoms of their disease, energy conservation techniques and relaxation positions to reduce dyspnea and usage of a specific inhaler.
OTHERAerobic Exercise Training
Exercise training will be comprised of cardiovascular endurance training with cycle ergometer and lower extremity strength training. The exercises will be done 3 days a week at the clinic under the supervision of physiotherapist. Total duration of exercise training will last for 8 weeks
