Surface Diaphragm EMG Evaluate the Clinical Efficacy of Pulmonary Rehabilitation in Patients With Chronic Obstructive Pulmonary Disease: a Multi Center Prospective Randomized Controlled Study
Pulmonary rehabilitation is recognized as a core component of the management of individuals with chronic obstructive respiratory disease, which has become first-line treatment besides drug therapy.
However, in the current clinical evaluation system of pulmonary rehabilitation, there is still a lack of simple, objective index,which can be monitored at any time.Neural respiratory drive , as an important physiological index, is closely related to the symptoms and the severity of the disease.
It may be a sensitive indicator to evaluate the effectiveness of pulmonary rehabilitation.
Surface EMGdi can accurately evaluate neural respiratory drive , its detection is non-invasive, simple and safety .
In recent years, with the development of signal detection and analysis technology, EMG recording is more stable, but as the related research samples were low, surface diaphragm EMG has not yet the establishment of standardization.
Therefore, based on the previous work, the project was carried out in a multicenter randomized controlled study,in which the stable stage of COPD patients were included in different ways of pulmonary rehabilitation training, a comprehensive clinical assessment will be conducted before and after training.
Compared with the traditional evaluation methods and standard esophageal diaphragmatic electromyography, surface EMGdi detect the changes of neural respiratory drive in patients with COPD,that can help to explore the application value of surface EMGdi in the assessment of chronic obstructive pulmonary disease with pulmonary rehabilitation, to provide a basis for the promotion of the diaphragm and the optimization of pulmonary rehabilitation program.

Conditions
Detailed Description
The patients with COPD will participate in a rehabilitation program for 52 weeks.
Participants in the proposed study will be randomly programmed into one of four intervention groups:
- Neither cycle training nor inspiratory muscle training.
- Cycle training program alone (performing on calibrated stationary cycle ergometer).
- Inspiratory muscle training alone (performing on threshold loading device).
- Combined cycle training and inspiratory muscle training(performing on calibrated stationary cycle ergometer and threshold loading device).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Control group
Neither cycle training nor inspiratory muscle training.
|
Neither cycle training nor inspiratory muscle training.
|
Experimental: Cycle training group
A calibrated cycle ergometer is used to do 30-minute cycling training session 3 days a week.
|
The most common device to perform cycle training is calibrated cycle ergometer.
|
Experimental: Inspiratory training group
A threshold loading device is used to perform 21-minute inspiratory muscle training 3 days a week.
|
Threshold loading device is used to perform inspiratory muscle training.
|
Experimental: Combined group
Calibrated cycle ergometer and threshold loading device are applied.A 30-minute cycle training is performed using calibrated cycle ergometer and a 21-minute inspiratory muscle training using threshold loading device 3 days a week.
|
Combined cycle training and inspiratory muscle training.The threshold loading device is composed of a mouth -piece attached to a small plastic cylinder that contains a spring-loaded poppet value.
The valve opens to permit inspiratory flow only once the person has generated adequate negative intrathoracic pressure to condense the spring.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Diaphragmatic function(composite outcome measure)
Time Frame: Change from baseline in diaphragm electromyogram.(8 weeks later, 26 weeks later, 52 weeks later)
|
Diaphragmatic function can be assessed by diaphragm electromyogram (EMGdi), which reflect the physiological activity of the diaphragm and indicate functional status of the central drive.
|
Change from baseline in diaphragm electromyogram.(8 weeks later, 26 weeks later, 52 weeks later)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Inspiratory muscle function(composite outcome measure)
Time Frame: Change from baseline in inspiratory muscle function.(8 weeks later, 26 weeks later, 52 weeks later)
|
Currently, the maximal inspiratory pressure (PImax) and maximal expiratory pressures(PEmax) are measured by a digital manometer (AZ-8205, AZ Instrument, Taichung City, Taiwan)and combined to evaluate inspiratory muscle function.
|
Change from baseline in inspiratory muscle function.(8 weeks later, 26 weeks later, 52 weeks later)
|
Pulmonary Function(composite outcome measure)
Time Frame: Change from baseline in pulmonary function.(8 weeks later, 26 weeks later, 52 weeks later)
|
Pulmonary function is measured using a spirometer(PonyFX 229, Cosmed, Rome, Italy) that is calibrated daily.The FEV1 and percent-of-predicted FEV1, FVC and percent-of-predicted FVC which are presented in one report are used to evaluate Pulmonary Function.
