Early pulmonary rehabilitation is recommended after an episode of severe exacerbation of chronic obstructive pulmonary disease (COPD). However, its implementation is challenging particularly as regard exercise training. Several studies showed that transcutaneous electrical nerve stimulation (TENS) could improve dyspnea and pulmonary function. The aim of this study is to assess the acute effect of TENS on exercise tolerance in post-exacerbation COPD patients

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Test with TENS | Experimental | Patients will perform one Constant Work-Rate Exercise Test at 80% of maximum workload with low frequency TENS |
|
| Test with sham-TENS | Sham Comparator | Patients will perform one Constant Work-Rate Exercise Test at 80% of maximum workload with low frequency sham-TENS |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| CWRT with low frequency transcutaneous electrical nerve stimulation | Other | 4 self adhesive surface electrodes will be positioned by pair on quadriceps. Patients will have a low frequency TENS for 20 min at rest. During this period, intensity will be increased every 5 minutes to the maximum tolerated by the patient (below pain threshold, sensation strong but comfortable). Thereafter, intensity is not increased anymore during the test. Current characteristics : Rehab 400, CefarCompex 5Hz 200 µs frequency bidirectional |
| Measure | Description | Time Frame |
|---|---|---|
| comparison of exercise tolerance | Comparison of endurance time (Tlim, in second) during constant workload testing (CWRET) under 2 conditions | two CWRET will be carried out in different days, separate from 24 hours minimum for a total time frame of 5 days maximum |
| Measure | Description | Time Frame |
|---|---|---|
| Difference in peripheral muscle oxygenation | Muscle oxygenation (arbitrary unit) will be evaluated using Near-infrared spectroscopy technology. | The outcome will be measure during every CWRET. The two CWRET will be carried out in different days, separate from 24H minimum for a total time frame of 5 days maximum. Data will be continuously collected during exercise |

sham transcutaneous electrical nerve stimulation
|
| CWRT with sham-low frequency transcutaneous electrical nerve stimulation | Other | 4 self adhesive surface electrodes are positioned by pair on quadriceps. Patients will have a sham-low frequency TENS for 20 min at rest. During this period, intensity will be increased for 1 minute to the maximum tolerated by the patient. After this procedure, intensity will be progressively setted back to 1mA. Current characteristics : Rehab 400, CefarCompex 5Hz 200 µs frequency bidirectional |
