Brief Summary

Fatigue is a prevalent symptom in Chronic Obstructive Pulmonary Disease (COPD) that limits patients in their daily living activities. It is now well established that COPD patients may have altered neuromuscular functions compared to healthy individuals. However, the different studies conducted on muscle fatigue in COPD have been done independently of any cognitive solicitation, yet present in most of daily living activities. Therefore, the aim of this research is to evaluate the impact of the disease on neuromuscular fatigue during dual-task situation (simultaneous accomplishment of a muscle contraction and a cognitive task). A better understanding of fatigue in COPD will promote the development of new perspectives in patient management. The hypothesis is that COPD patients will exhibit increased fatigue level (compared to healthy subjects), particularly during dual-task situation. It is assumed that the higher negative effect associated with the dual-task will be related to different neurophysiological mechanisms (i.e., neuromuscular fatigue, autonomic nervous system activity, mental fatigue).

Outcome Measures

Primary Outcomes (1)

  • Endurance time differences between simple and dual-task conditions, in COPD patients compared to healthy participants

    The endurance times will correspond to the duration of the fatiguing tasks (simple and dual-task). The endurance time differences between simple and dual-task conditions will be calculated as follows : Endurance time in simple task condition - Endurance time in dual-task condition = Difference of endurance time.

    7 days

Secondary Outcomes (4)

  • Neuromuscular fatigue of knee extensors

    About each minute during the fatiguing tasks lasting about 20 minutes

  • Autonomic nervous system activity

    Continuously during the fatiguing tasks lasting about 20 minutes

  • Mental fatigue

    Continuously during the fatiguing task in dual-task condition, which should last about 20 minutes

  • Psychological state

    Before, during and after fatiguing task lasting about 20 minutes

Interventions

Firstly, the participants have to perform the fatiguing task in simple task condition (control condition, i.e., muscle contraction alone). Secondly, few days later (between 3 and 7 days later), the participants have to perform the same fatiguing task with a concomitant memory cognitive task (i.e. dual-task condition).

Evaluation of fatigue in control patients (condition 1)Evaluation of fatigue level in BPCO patients (condition 1)

Firstly, the participants have to perform the fatiguing task in dual-task condition (i.e. muscle fatiguing contraction with a concomitant memory cognitive task). Secondly, few days later (between 3 and 7 days later), the participants have to perform the same muscle fatiguing task without a concomitant memory cognitive task (i.e. control condition).
