Descrizione dettagliata
Multiple sclerosis (MS) is the most common non-traumatic disabling neurologic condition of young adulthood, affecting more than 2.5 million people worldwide. Permanent disability in MS is caused by recurrent demyelination due to episodic inflammation, followed by neuronal damage, axonal degeneration, and progressive failure of remyelination. There is an urgent need to restore activity and participation in people with MS (pwMS), and remyelination is the most promising therapeutic strategy to accomplish this goal.
Remyelination in pwMS will likely require integration of pharmacologic and rehabilitative approaches to ensure effective remyelination of appropriate neural pathways. Aerobic exercise is an ideal complement to remyelinating medications because aerobic exercise 1) improves walking function in pwMS, and 2) promotes remyelination in animal models both independently and synergistically with medications. However, there are many unknowns that need to be addressed before aerobic exercise can be explored in multimodal clinical trials for remyelination. First, it is imperative to understand how myelination impacts disability in MS, as many other factors could contribute to reduced activity and participation. Additionally, as remyelination occurs over 12 to 24 weeks, it is imperative to establish the feasibility of similar duration of aerobic exercise interventions, and explore if exercise independently influences established remyelination outcomes before integration into multimodal strategies.
This is a randomized, single-blind, parallel clinical trial of a 24-week aerobic stationary cycling intervention to determine feasibility and explore if aerobic exercise independently promotes remyelination in pwMS.

Somatosensory Evoked Potentials
Lasso di tempo: From baseline to week 24
|
Somatosensory evoked potentials (SSEPs) are a measure of functional myelination of the somatosensory tracts (i.e., the time it takes for a sensory signal to travel from the limb to the cortex of the brain). Z-scores were calculated for each leg, adjusting for participant height. A Z-score measures how many standard deviations a specific data point is from the average (mean) of a dataset (where a Z-score of 0 represents the population mean). Averaged Z-scores of the cortical latencies of both legs (i.e., P40) were compared between baseline and week 24 (post-intervention). Z-scores increase with myelin damage in multiple sclerosis (MS). Those with an average Z-score of ≥2 were considered abnormal. |

Higher scores represent better cognitive processing speed and executive function. Scores can range to 0 (i.e., no correct number-symbol pairings) to a theoretically infinite score. |

Quality of Life in Neurological Disorders (Neuro-QoL)
Lasso di tempo: From baseline to weeks 24
|
Quality of Life in Neurological Disorders (Neuro-QoL) questionnaires are patient-reported outcomes of upper and lower extremity function, depression, sleep, and self efficacy. The scores are based on T-scores which is a standardized score with a set mean of 50 and a standard deviation of 10. This scale is used to convert raw data into positive, comparable scores (e.g., T = z × 10 + 50). Increased symptom severity is reflected by lower Neuro-QoL Upper Extremity Function scores, lower Neuro-QoL Lower Extremity Function scores, higher Neuro-QoL Depression scores, higher Neuro-QoL Sleep scores, and lower Self Efficacy scores. |
