Fatigue in Long COVID (FALCON)

2026年7月7日 更新者：Jason Busse、McMaster University

Fatigue in Long COVID Managed With Conservative Care: An International, Randomized Controlled Trial (FALCON Trial)

Long COVID affects about 6 in 100 people after a COVID-19 infection. It can cause ongoing problems like ongoing tiredness, muscle pain, and "brain fog." We know very little about which treatments might be helpful for long COVID.

The goal of this trial is to compare two treatments for people with long COVID to try to manage their symptoms. The main question is to assess whether the Lightning Process is effective for people living with long COVID compared to activity pacing. Each person will be placed into one of the two groups randomly (by chance, like flipping a coin). Activity pacing helps people balance rest and daily activities. The Lightning Process teaches ways to change thought patterns and body responses to symptoms. We will include 100 adults with long COVID. Everything will be done online, including filling out surveys about health and daily life. The goal is to find out which approach helps people feel better and improve their daily activities.

詳細な説明

The COVID-19 pandemic presented an unprecedented global health crisis, affecting millions globally and causing significant health and economic consequences. Although most people recover from acute SARS-CoV-2 infection, a substantial minority, approximately 6 to 15%, develop persistent symptoms that last for months and impair daily function, commonly referred to as post-COVID-19 condition or long COVID. Common symptoms of long COVID include fatigue, myalgia, dyspnea, sleep disturbance, and cognitive dysfunction ("brain fog"). The prevalence of long COVID is difficult to establish because most symptoms are nonspecific and many data sources rely on study designs that cannot confidently attribute symptoms to prior SARS-CoV-2 infection. Despite this uncertainty, converging evidence points to a large global burden, with >65 million people estimated to be living with functional limitations attributed to long COVID. The Lightning Process (LP), is a mind-body training program that is hypothesized to help individuals to develop a conscious influence on their level of functioning, using practical tools such as discussion, gentle movement and meditation-like techniques. Emerging evidence suggests that gradually re-engaging long COVID patients in physical activation and modifying unhelpful beliefs may promote recovery. There are currently no established treatments for long COVID, and patients often use activity pacing to manage their symptoms. The purpose of this trial is to establish the efficacy and safety of LP vs. activity pacing in adults living with long COVID. We hypothesize that in our trial, people randomized to LP will report greater improvement in fatigue compared to those receiving activity pacing. Our trial will enroll people living with long COVID who are motivated and show willingness to change their condition through intervention. The trial will assess whether, among adults living with long COVID (post COVID-19 condition) and persistent, function limiting symptoms, LP improves fatigue and other patient important outcomes, compared to activity pacing.

The primary objective is to assess the effect of LP vs. activity pacing on fatigue among adults with long COVID.

The secondary objectives are to assess the effect of LP vs. activity pacing on

  • Physical functioning
  • Pain severity
  • Post exertional malaise
  • Health related quality of life
  • Somatic symptom severity
  • Functional impairment
  • Respiratory function
  • Adverse events and serious adverse events

Both LP and pacing interventions span 26 weeks. Patients assigned to the LP intervention will complete a brief preparatory phase, then attend three consecutive core sessions. The LP protocol includes two follow-up calls one week apart and a booster call at week 26. Patients assigned to the pacing intervention complete 15 sessions over 24 weeks-four weekly sessions, then sessions every two weeks until week 26.

Participants will complete outcome measures at 6 months, coinciding with the immediate the end of the intervention, and at 9 and 12 months. The post-treatment time point estimates the proximal effect of LP compared to pacing, where contamination is lowest, co-interventions are least likely to diverge across arms, and any harms (e.g., post-exertional worsening) are most plausibly related to the assigned strategy.

介入・治療
実験的：Lightning Process
Lightning Process is a mind body intervention that focusses on identifying and interrupting negative thoughts that may affect fatigue.
行動：Lightning Process
LP is a mind body intervention which is delivered over 3 consecutive days to individuals or in groups via video technology. The sessions are approximately 4 hours long. Experienced LP practitioners will deliver the LP intervention remotely and individually. The intervention is comprised of a preparation phase, core sessions, and follow-up. Preparation consists of an audio home-study module (about 4 hours total) and about 1 hour of preparatory coaching by telephone or videoconference in the days to weeks before delivery of the LP intervention to orient participants to the approach and address any questions.
アクティブコンパレータ：Activity pacing
Activity pacing is a self-management strategy that balances activity and rest to manage fatigue, allowing individuals to maintain consistent energy levels throughout the day.
他の：Activity Pacing
Activity Pacing, a self-management strategy that balances activity and rest to manage fatigue, allowing individuals to maintain consistent energy levels throughout the day. The aim of activity pacing is to avoid symptom exacerbations whilst achieving as much as possible with limited energy. Pacing focusses on developing awareness not only of the symptoms but also more subtle indicators that herald a future exacerbation of symptoms (listening to your body) and becoming aware of effect of activity or lack of rest on disability. Senior occupational therapy students will deliver activity pacing remotely and individually by videoconference.

メジャーの説明
時間枠
Fatigue (Checklist Individual Strength-Fatigue)
時間枠：12 months
The primary outcome will be the mean change in fatigue scores between Lightning Process and activity pacing group at 12 months post randomization. This will be assessed on the fatigue domain of the 8-item Checklist Individual Strength (CIS-fatigue) at 12 months follow-up. The CIS-fatigue domain consists of 8 items with a total score ranging from 8 to 56, with higher scores indicating more severe fatigue.
12 months

二次結果の測定

結果測定
メジャーの説明
時間枠
Respiratory function (Dyspnea-12)
時間枠：6 months, 9 months, and 12 months
Change in respiratory functioning will be assessed with the Dyspnea-12 (D-12) Scale which measures the current level of a patient's breathlessness severity, incorporating both physical and affective aspects, and does not depend on activity limitation. Each item scored from 0-3, for a total score range of 0-36. Higher scores indicate worse dyspnea.
6 months, 9 months, and 12 months
Post Exertional Malaise (De Paul Symptom Questionnaire)
時間枠：Baseline, 6 months, 9 months, and 12 months
Change in post exertional malaise (PEM) will be measured using a brief questionnaire derived from De Paul Symptom Questionnaire (DSQ). It is a 5-item self-report tool that evaluates common symptoms of long COVID, including worsening after physical or mental activity, recovery duration and activity intolerance. Each item is scored 0-4 on 5-point Likert scale. A score of ≥2 for frequency and ≥2 for severity on any item suggests PEM.
Baseline, 6 months, 9 months, and 12 months
Daily Pain (Brief Pain Inventory Short Form)
時間枠：6 months, 9 months, and 12 months
Change in pain will be assessed using Brief Pain Inventory short form (BPI-SF). This is a 9-item questionnaire used to evaluate the severity of a patient's pain and the impact of their pain on daily functioning. The BPI-SF evaluates pain severity at its worst, least, and average during the previous week, as well as current pain level, with 0 representing no pain and 10 the worst pain imaginable.
6 months, 9 months, and 12 months
Fatigue (Checklist Individual Strength-Fatigue)
時間枠：6 months and 9 months
Change in fatigue scores will be measured at 6 and 9 months post randomization. This will be assessed on the fatigue domain of the 8-item CIS-fatigue scale at 6 and 9 months follow-up.
6 months and 9 months
Physical function (SF-12)
時間枠：Baseline, 6 months, 9 months, and 12 months
Change in physical functioning will be measured using Short Form Health Survey (SF-12) scale, a 12-item questionnaire that assesses physical and mental health status.
Baseline, 6 months, 9 months, and 12 months
Health related quality of life (EuroQol-5 Dimensions)
時間枠：Baseline, 6 months, 9 months, and 12 months
Health related quality of life will be measured using the EuroQol-5 Dimensions (EQ-5D) scale that provides a generic measure of health for clinical and economic appraisal. Its a continuous (scale 0-100). Higher scores relate to better health.
