Effects of the Cross-Training in Patients With Multiple Sclerosis (CTSM)

Detailed Description
Muscle weakness is a major disability that is responsible for deeply reducing the overall quality of life (QoL) of patients with Multiple Sclerosis (MS). Research has shown that strength training (ST) has a significant positive effect on the performance of daily living activities in people with MS, resulting in an increased QoL. Several ST methods are currently employed for reducing strength impairment in MS but no one regimen has been portrayed as superior to others. When strength impairment is prominently lateralized to one limb, training is commonly addressed to the weaker side in order to balance the deficit. However, such ST may not always be applicable to a severely weakened limb that is too compromised to sustain it. For these selected patients we hypothesize that training the less affected limb with a Cross Training (CT) approach may overcome the problem, also avoiding patients' frustration and potential withdrawals from rehabilitation programs.
Aim of this project is to investigate and compare in two groups of selected MS patients, with a marked asymmetry of strength, the effects induced on dynamometric, neurophysiological, functional and clinical outcomes by a CT of the less-impaired leg (CT group) compared to a ST of the more-impaired leg (ST group). In order to make comparisons with a population which is not exposed to the condition MS, a third group composed of healthy subjects will also be included in the study.
The research plan will be articulated in 5 phases (recruitment, baseline assessment, 6 week-intervention phase, post-intervention assessment and follow up at 12 weeks).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Cross-Training healthy subjects
A cohort of healthy subjects (N=15) will undergo a phase of intervention consisting of cross-training of the stronger limb employing an isokinetic contraction regimen at maximal intensity.
|
The phase of intervention will consist of a 6-week cross-training of the stronger limb employing an isokinetic contraction regimen at maximal intensity.
|
Active Comparator: Standard-Training multiple sclerosis
A cohort of patients with multiple sclerosis (N=15), presenting with a marked asymmetry in limb strength, will undergo a standard-training of the more-impaired limb employing an isokinetic contraction regimen at maximal intensity.
|
The phase of intervention will consist of a 6-week standard strength training of the more-impaired limb employing an isokinetic contraction regimen performed at maximal intensity.
|
Experimental: Cross-Training multiple sclerosis
A cohort of patients with multiple sclerosis (N=15), presenting with a marked asymmetry in limb strength, will undergo a cross-training of the less-impaired limb employing an isokinetic contraction regimen at maximal intensity.
|
The phase of intervention will consist of a 6-week cross-training of the less-impaired limb employing an isokinetic contraction regimen at maximal intensity.
|
No Intervention: Healthy Control
A cohort of healthy subjects (N=15) will undergo baseline assessment and a second evaluation after one month of no-intervention

What is the study measuring?
Primary Outcome Measures

Measure Description |
Time Frame |

Muscular strength
Time Frame: Muscular strength will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Strength changes in the weaker side compared to the contralateral, through isokinetic dynamometry.
|
Muscular strength will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Neural adaptations to Cross Training
Time Frame: Neural adaptations will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Neural adaptations to CT occurring at cortical and/or spinal level, through transcranial magnetic stimulation (TMS) and peripheral electrophysiological recordings.
|
Neural adaptations will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Walking performance
Time Frame: It will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Regarding the clinical and functional relevance to MS patients, changes from baseline in walking performance will be assessed through 6-Minute Walking Test (6MWT), which has been demonstrated to be a feasible, reproducible and reliable measure in MS and to be strongly correlated to subjective measures of ambulation; 10 Meter-Walk Test (10MWT), which estimates the walking speed at both comfortable and maximal velocities.
|
It will be assessed at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Fatigue
Time Frame: Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Modified Fatigue Impact Scale (MFIS): extracted from the Multiple Sclerosis Quality of Life Inventor.
It consists of 21 items and provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning.
|
Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Executive functions
Time Frame: Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Frontal Assessment Battery (FAB): it tests executive functions, in a form of an interview with 6 functional tasks covering 5 domains: memory, planning, attention, reflex and visual spatial.
The FAB correlates with dysfunction in a variety of cognitive domains including attention, memory, and executive functions.
|
Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Spasticity symptom severity
Time Frame: Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
|
Modified Ashworth Scale: it is a widely used qualitative scale for the assessment of spasticity symptom severity and measures resistance to passive stretch, scoring from 0 (no increase in tone) to 4 (affected parts rigid in flexion or extension).
|
Assessment at baseline, within one week from the completion of the 6-week rehabilitation phase and at 12-week follow up.
