Effects of Lumbar Transcutaneous Electrical Nerve Stimulation on Exercise Performance in Patients With Chronic Obstructive Pulmonary Disease (LENS-REHAB)
Effects of Lumbar Transcutaneous Electrical Nerve Stimulation on Exercise Performance in Patients With Chronic Obstructive Pulmonary Disease : A Pilot Study
Chronic obstructive pulmonary disease is a leading cause of morbidity and mortality worldwide.
Pulmonary rehabilitation effectively improves outcomes in patients with chronic respiratory disease. There is a link between training intensity and physiological improvements following pulmonary rehabilitation. However, high intensity training is not sustainable for every patients.
Therefore, actual strategies for pulmonary rehabilitation aimed at decreasing dyspnea to improve muscle work.
Electrical muscle stimulation is widely used during rehabilitation to promote muscle function recovery. Transcutaneous electrical nerve stimulation was recently used to relief dyspnea and improve pulmonary function in patients with chronic respiratory disease. Moreover, spinal anesthesia with fentanyl has been shown to be effective in improving exercise tolerance in patients with chronic obstructive pulmonary disease (inhibiting group III and IV muscle afferents). As transcutaneous electrical muscle stimulation stimulates the same receptors in the spinal cord dorsal horn as fentanyl, it is hypothesized that it could also improve exercise capacity.
Therefore, the aim of this study is to assess wether transcutaneous electrical stimulation (high or low frequency) is effective in improving exercise capacity in patients with severe to very severe chronic obstructive pulmonary disease.
Study Overview

---|---|
Experimental: CWT with high-frequency electrical nerve stimulation
This study has a cross-over design.
Patients will achieve CWT with either sham, high-frequency or low-frequency lumbar transcutaneous electrical nerve stimulation in a randomised order.
|
4 self adhesive surface electrodes are positioned by pair at the L3-L4 level, laterally. Stimulation is setted at rest, 10min before constant workload testing. During this period, intensity is increased every 3minutes to the maximum tolerated by the patient (pain threshold). Thereafter, intensity is not increased anymore during the test. It is explained to the patient that he might or no experience the electrical stimulation sensation. Current characteristics : 100Hertz, 100ms, bidirectional. Constant workload testing : 60-70rpm ; 75% Wpic ; up to exhaustion or rpm < 60 during more than 10s. |
Experimental: CWT with low-frequency electrical nerve stimulation
This study has a cross-over design.
Patients will achieve CWT with either sham, high-frequency or low-frequency lumbar transcutaneous electrical nerve stimulation in a randomised order.

During this period, intensity is increased every 3minutes to the maximum tolerated by the patient (pain threshold). Thereafter, intensity is not increased anymore during the test. It is explained to the patient that he might or no experience the electrical stimulation sensation. Current characteristics : 4Hertz, 100ms, bidirectional. Constant workload testing : 60-70rpm ; 75% Wpic ; up to exhaustion or rpm < 60 during more than 10s. |
Experimental: CWT with sham electrical nerve stimulation
This study has a cross-over design.
Patients will achieve CWT with either sham, high-frequency or low-frequency lumbar transcutaneous electrical nerve stimulation in a randomised order.
|
The procedure is the same as high-frequency transcutaneous electrical stimulation but intensity is progressively setted back to 1mA (over a 45sec period) after every increment so that constant workload testing is performed with 1mA.
