Summary

Multiple Sclerosis (MS) is a chronic neurological disease that can affect daily functioning, mobility, and overall quality of life. High-Intensity Interval Training (HIIT) is known to be a time-efficient exercise approach that improves exercise capacity and reduces fatigue in MS. However, current research lacks sufficient data on how HIIT affects individuals with different levels of disability.

The main purpose of this study is to evaluate the effects of a stationary bicycle-based HIIT protocol on maximum walking distance, fatigue, balance, muscle strength, endurance, gait speed, and quality of life in MS patients across three different disability levels: mild, moderate, and severe (classified according to Expanded Disability Status Scale - EDSS scores).

Participants will complete a cycle ergometer-based HIIT program. Assessments will be conducted at three time points:

Before starting the exercise program (baseline)

Immediately after completing the program (post-treatment)

4 weeks after the completion of the program (follow-up)

To ensure unbiased results, a triple-blind design will be used, meaning the outcome assessor, the treating physiotherapist, and the data analyst will be blinded to group assignments. The findings aim to help clinicians tailor personalized, effective HIIT protocols based on a patient's specific disability level rather than using a standardized, one-size-fits-all approach in MS rehabilitation.

Interventions

BEHAVIORAL

High-Intensity Interval Training

All exercise sessions in our study will be conducted using a bicycle ergometer (Monark Cardio Care 827 X, Monark Exercise AB, Sweden). The HIIT protocol will consist of five 3-minute high-intensity intervals performed at 80-100 revolutions per minute, corresponding to 85-90% of maximum heart rate. Between these intervals, active rest periods will be implemented, during which cadence is reduced to 50-60 revolutions per minute for 1.5 minutes to lower heart rate to 50-60% of maximum heart rate. The total training duration is planned to be 20 minutes, consisting of a 2-minute warm-up at the beginning and a 2-minute cool-down at the end. Sessions will be conducted three times a week. The total treatment duration is planned to be 8 weeks.
