简要总结
A prospective assessor-blinded randomized clinical trial investigating the effect of aerobic exercise therapy or cognitive behavioural therapy on fatigue in patients with myasthenia gravis.
详细描述
This study will be a prospective assessor-blinded randomized controlled trial comparing AET and CBT with usual care (UC). For an individual participant, the overall study duration will be 52 weeks with a total intervention duration of 16 weeks. After 32 and 52 weeks the investigators will analyse the data from the activity tracker and approach each participant to digitally complete a total of three questionnaires. After 32 weeks the researchers will be unblinded and the study will proceed as an open-label extension study.
After signing the informed consent form, an activity tracker (Withings Pulse HR) will be provided to all participants. After a four week observation period to evaluate the baseline levels of daily activity, participants will visit the LUMC for baseline measurements and a blood test. After obtaining these baseline characteristics, all participants will be randomly assigned to either AET, CBT or UC.
Participants in the AET group start with an intake meeting with a physical therapist. AET will consist of three weekly sessions of aerobic workouts on a bicycle ergometer for a period of 16 weeks. The first training session will be supervised by an experienced physical therapist at the LUMC. Subsequently, participants will perform the remaining workouts at home. One session per week will be carried out independently at home. The other two sessions will be digitally supervised via a digital connection by students, who will be trained and supervised by an experienced physical therapist. During the intervention, training intensity will be adjusted based on the participant's rate of perceived exertion (Borg Rating of Perceived Exertion (RPE) scale). During each session, the participant is also able to adjust the wattage of that specific training. Training activity and execution will be monitored remotely using the bicycle ergometer and the activity tracker. Adherence and reasons for possible non-adherence will be monitored by the students. Outcome measures will be collected on follow-up immediately after the 16-week intervention.
Participants in the CBT group start with an online intake meeting with a psychologist. The entire CBT program will be followed digitally through an online platform and will span 12-16 weeks. The program will be tailored to the individual participants' needs and preferences. Every week or every two weeks, the psychologist provides feedback on the finished sessions and gives new assignments. If necessary, the psychologist will contact a participant by phone for additional support. Outcome measures will be collected on follow-up immediately after the 16-week intervention.
The outcome measures of the participants in the UC group are obtained after the four week observation period and after 20 weeks follow-up. Participants are not restricted in their activities, but will be instructed not to start a new exercise or cognitive behavioural program. Chronic physical therapy and psychological counselling in the context of usual care are allowed to continue. After the 32-week follow-up, the participants in the UC group have the option to follow a modified version of the AET or CBT interventions without supervision.

研究组 & 干预措施
Usual care
Participants are not restricted in their activities, but will be instructed not to start a new exercise or cognitive behavioural program. Chronic physical therapy and psychological counselling in the context of usual care are allowed to continue.
干预措施: Usual care (Other)
Cognitive behavioural therapy
The entire CBT program will be followed digitally through an online platform and will span 12-16 weeks. The program will be tailored to the individual participants' needs and preferences. Every week or every two weeks, the psychologist provides feedback on the finished sessions and gives new assignments. If necessary, the psychologist will contact a participant by phone for additional support.
干预措施: Cognitive behavioural therapy (Behavioral)
Aerobic exercise therapy
AET will consist of three weekly sessions of aerobic workouts on a bicycle ergometer for a period of 16 weeks. The first training session will be supervised by an experienced physical therapist at the LUMC. Subsequently, participants will perform the remaining workouts at home. One session per week will be carried out independently at home.

结局指标
主要结局
A change in CIS-fatigue in the AET and CBT group, compared to UC, before and after intervention.
时间窗: Assessed after 4 weeks and 20 weeks.
Fatigue measured on the Checklist Individual Strength (CIS-) fatigue subscale. The CIS-fatigue consists of eight questions on fatigue experienced during the previous two weeks. Each question is scored on a 7-point Likert scale and a score ≥ 27 indicates increased fatigue and a score ≥ 35 indicates severe fatigue. A higher score means more severe fatigue. A decline of ≥8 is considered clinically relevant. The total score of the fatigue subscale ranges from 8-56 (the total score of the CIS questionnaire ranges from 20-140).
