About this study

Official title: Towards a Better Understanding of Neuromuscular Alterations and Fatigue in Chronic Obstructive Pulmonary Disease (COPD)

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).

Read the detailed description

This study will include three experimental sessions for both COPD patients and healthy participants. These experimental sessions will be performed on three separate days. Each session will last between 1.5 and 2 hours.

The first session will correspond to a familiarization session with the different tests that will be performed during the two next sessions. During this first session, different functional tests will be also performed : 1-minute sit-to-stand tests and postural tests, with and without a concomitant cognitive task.

The second and third sessions will correspond to experimental sessions during which the participants will accomplish a fatiguing task in single or dual-task situation (randomized order). The cognitive task will be a memory cognitive task, called n-back task. The fatiguing tasks will involve submaximal isometric contractions of the knee extensors performed until task failure. The neuromuscular fatigue will be evaluated regularly during the fatiguing tasks (i.e. about each minute) using the magnetic stimulation of the femoral nerve in order to assess to central and peripheral determinants of the neuromuscular fatigue. Moreover, the autonomic nervous system activity (via cardiac recordings), perceived exertion and cognitive performance (in dual-task situation) will be continuously recorded during the fatiguing tasks. Before and after each fatiguing tasks, several questionnaires will be completed (i.e. mood, motivation, subjective workload) in order to evaluate the psychological determinants of performance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Single then dual task situationOther

    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).

  • Dual then single task situationOther

    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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 7 days

Secondary outcomes (4)
  1. Neuromuscular fatigue of knee extensors

    The neuromuscular fatigue will be evaluated regularly during the fatiguing tasks using the magnetic stimulation of the femoral nerve , during and after maximal voluntary contraction. Moreover, the muscle activity of the Vastus Lateralis, using non-invasive surface electromyography (sEMG), will be continuously recorded during the fatiguing tasks.

    Measured: About each minute during the fatiguing tasks lasting about 20 minutes

  2. Autonomic nervous system activity

    Autonomic nervous system activity will be continuously recorded during the fatiguing tasks using cardiac measurements .

    Measured: Continuously during the fatiguing tasks lasting about 20 minutes

  3. Mental fatigue

    The influence of mental fatigue on the performance will be assessed using the cognitive performance (i.e. rate of correct answers and reaction time) that will be continuously recorded during fatiguing dual-task.

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

  4. Psychological state

    Psychology influence on task performance will be evaluated with questionnaires before, during and after the task. For motivation: 14 items, scores from 0 (not at all) to 4 (extremely), 2 subscales assessing intrinsic and success-based motivation (scores from 0 to 28). For mood: 24 adjectives, scores from 0 (not at all) to 4 (extremely), 6 subscales evaluating fatigue, confusion, vigor, depression, tension and anger (scores from 0 to 16). For Rating-of-Fatigue scale: one score from 0 (not tired) to 10 (exhaustion). For dyspnea: one score from 0 (nothing) to 10 (extremely strong). For Task Load Index: 6 subscales, from 0 (very low) to 20 (very high), measure mental and physical difficulties, time pressure, performance perception, effort perception and frustration. For Sleep Quality Index: 24 questions, 7 subscales from 0 to 3 evaluating subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, sleep medication and day dysfunction due to sleepiness.

    Measured: Before, during and after fatiguing task lasting about 20 minutes
