High-intensity Resistance Training in People With Multiple Sclerosis Experiencing Fatigue
Study Details
Study Description
Brief Summary
Fatigue is one of the most frequently reported and disabling impairments in multiple sclerosis (MS) and is associated with activity limitations, participation restrictions and reduced health-related quality of life (HRQL).MS fatigue is thought to be related to the disease itself, where increased levels of inflammatory biological markers (cytokines) are contributing. Resistance training may have an anti-inflammatory effect where a higher intensity is thought to have a more profound effect. Moderate-intensity resistance training is well tolerated in people with MS (PwMS) and can reduce self-reported fatigue. There is, however, a lack of high-quality studies including only fatigued PwMS when evaluating exercise regimes. Furthermore, the optimal dose (i.e. the combination of duration, frequency and intensity) is not known. Our hypothesis is that high-intensity resistance training will have positive effects in fatigued PwMS on functioning (fatigue, mood, activities and participation) and wellbeing/HRQL; and a positive immunomodulatory effect measured by inflammatory biological markers in blood. Further, that high-intensity resistance training twice a week will be superior to once a week

Detailed Description
Multiple sclerosis (MS) is chronic inflammatory neurodegenerative disease. About two-thirds of persons with MS (PwMS) report MS-related fatigue. It is a most disabling impairment and is associated with activity limitations, participation restrictions and reduced health-related quality of life (HRQL). MS fatigue may be related directly to the disease, e.g. inflammation. Resistance training can have direct effects on the MS disease by modulating cytokine levels, where a higher intensity is thought to have a more profound effect. Thus, there are reasons to hypothesise that high-intensity resistance training might reduce fatigue in PwMS. There are, however, no randomized controlled trials (RCTs) on resistance training in PwMS with fatigue. Although the recommendation of resistance training for adults with chronic diseases is twice a week, most primary health-care providers in Sweden only offer supervised training once a week for a limited period, e.g. 8-12 weeks. Thus, our aims are to evaluate the effects of 12 weeks high-intensity resistance training on functioning (fatigue, mood, activities and participation), wellbeing/HRQL and on inflammatory biological markers (e.g. cytokines) in blood. In this two-armed single-blinded RCT, 90 PwMS with fatigue will be recruited and randomly assigned to receive high-intensity resistance training under the supervision from a physiotherapist twice a week (group A) or once a week (group B). Primary outcome is fatigue measured with a patient reported outcome, i.e. the Fatigue Scale for Motor and Cognitive Functions (FSMC), and a change-score of ten points is considered clinically meaningful. Secondary outcomes include measures of mood, participation, self-perceived impact of MS, wellbeing/HRQL and inflammatory biological markers in blood. Data will be collected at baseline and within a week after the last training session of the 12-week intervention. All participants will after the end of intervention be offered a prescription of physical activity (FaR), and have the opportunity for follow-up telephone calls at 3-, 6- and 12 months after the end of the intervention. Assessment of fatigue will also be performed at these follow-up telephone sessions. Fatigue assessments from a natural history cohort (Combat study) will be available for comparisons of natural fluctuations of fatigue.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Group A The program consists of high-intensity resistance training for 60 minutes twice a week for group A during 12 weeks at the Karolinska University Hospital under the supervision of a physiotherapist. Participants in group A will have different possible training alternatives every week to ensure availability, and they will train in groups of three to five persons/session. |
Other: High-intensity resistance training
The program consists of high-intensity resistance training for 60 minutes twice a week (group A) during 12 weeks
|
| Active Comparator: Group B The program consists of high-intensity resistance training for 60 minutes once a week for group B during 12 weeks at the Karolinska University Hospital under the supervision of a physiotherapist. Participants in group B will have different possible training alternatives every week to ensure availability, and they will train in groups of three to five persons/session. |
Other: Low frequency of high-intensity resistance training
The program consists of high-intensity resistance training for 60 minutes once a week (group B) during 12 week

Outcome Measures
Primary Outcome Measures
- Fatigue Scale for Motor and Cognitive Functions [Directly after the intervention (ie change from assessments at baseline to follow-up after the 12 week intervention)]
Fatigue measured with the FSMC, minimum value 20, maximum value 100, higher scores mean a worse outcome
Secondary Outcome Measures
- Fatigue Severity Scale [Directly after intervention]
Fatigue measured with the FSS, minimum value 1, maximum value 7, higher scores mean a worse outcome
- Hospital Anxiety and Depression Scale [Directly after the intervention]
Mood measured with HADS, Anxiety and depression subscales, minimum value 0, maximum value 21, higher scores mean a worse outcome
- Occupational Gaps Questionnaire [Directly after the intervention]
Participation in everyday occupations measured with the OGQ, minimum value 0, maximum value 30, higher scores mean a worse outcome
- Multiple Sclerosis Impact Scale-29 [Directly after the intervention]
Health-related quality of life/impact of MS measured with the MS Impact Scale-29, Physical and psychological subscales, minimum value 0, maximum value 100, higher scores mean a worse outcome
- Euroqool five dimension five level [Directly after the intervention]
Wellbeing/health-related quality of life measured with the EQ-5D-5L, minimum value 0, maximum value 1, higher scores mean a better outcome
- Euroqool visual analogue scale [Directly after the intervention]
Wellbeing/health-related quality of life measured with the EQ VAS, minimum value 0, maximum value 100, higher scores mean a better outcome
- Multiplex proteomic immunoassay and enzyme-linked immunosorbent assay [Directly after the intervention]
Analyses of inflammatory biological markers (cytokines) in blood will be analysed, a minimum and maximum value can not be specified, and higher or lower values will have different meaning depending on which biological marker (cytokine)
