The aim of the study is to analyze the effects of Nordic Walking and free walking in the clinical-functional, postural balance, motor control, muscular echographic quality, and gait analysis (pendulum gait mechanism), in people with Multiple Sclerosis.
Objective: Analyze the effects of Nordic Walking and free walking in the clinical-functional parameters, postural balance, muscular echography quality, pendulum gait mechanism, in people with Multiple sclerosis. Experimental Design: Randomized controlled multicenter clinical trial with translational study characteristics. Search Location: Exercise Research Laboratory at the School of Physical Education, Physiotherapy and Dance, Federal University of Rio Grande do Sul, Brazil, and University of Pavia, on Department of Public Health, Experimental Medicine and Forensic Sciences, Pavia, Italy. Participants: 60 patients from the Unified Health System (UHS) of both sexes, from 20 to 75 years old, diagnosed with multiple sclerosis, sedentary. Interventions: In this research, four groups of patients with multiple sclerosis will receive intervention during 4 months of different physical therapy programs (Nordic walking and free walking), who will receive telephone guidance for performing home-based exercises. The training programs will have a duration of 3 months and will be periodized so that the duration of the sessions is matched between them. The intensity of the interval training will be manipulated by the subjective effort scale (Borg) and by the heart rate, with predetermined series durations. All training programs will have a frequency of two sessions per week and a duration of 60 minutes. To evaluate the effects of the training, evaluations will be performed before and after the training period: 1) Basal (month 0): initial pre-training evaluation; 2) month 4: Evaluation 48h after the last training session. Outcomes: clinical-functional parameters, postural balance, muscular echography quality, pendulum gait mechanism, and biochemistry. Data Analysis: Data will be described by average values and standard deviation values. The comparisons between and within groups will be performed using a Generalized Estimating Equations (GEE) analysis, adopting a level of significance (α) of 0.05. Expected Results: The intervention groups of the Nordic walking are expected to be more effective in all outcomes analyzed, especially improving functional mobility when compared to the control group of unsupervised home exercises. In addition, it is expected that the results of the research will be expandable and the possibility of future developments in the scientific, technological, economic, social, and environmental fields and that they will be implemented in the Unified Health System (UHS).

Test Timed Up and Go
Test Timed Up and Go: This test evaluates the mobility functional in three meters of self-selected speed (TUGSS) or at forced speed (TUGFS) \[Time Frame: Change from baseline at 12 weeks\]
Time frame: Change from baseline at 12 weeks
Locomotor Rehabilitation Index
The Locomotor Rehabilitation Index is a method of determining how close is the SSW compared to the Optimum Speed (Vopt).
Time frame: Change from baseline at 12 weeks
Self-selected walking speed
SSWS This outcome will be measure in test of treadmill walking
Time frame: Change from baseline at 12 weeks
Optimal Walking Speed (OPT)
Optimal Walking Speed (OPT) This outcome will be measure through of the registered image movement analysis using the three-dimensional motion analysis system (VICON) of the walking test on treadmill.
Time frame: Change from baseline at 12 weeks
Quality of life (QoL)
Quality of life (QoL) The quality of life will be estimated using the World Health Organization Quality of Life. (WHOQOL-short domains: physical, psychological, social relationships, environment, and general quality of life) and (WHOQOL-Long domains: sensory abilities, autonomy, Past. Present and Future Activities, social participation, death and dying, intimacy, and general quality of life).
Time frame: Change from baseline at 12 weeks

Depressive symptoms
This outcome will be measure for the Geriatric Depression Scale - 15 item. The scale consists of 15 dichotomous questions in which participants are asked to answer yes or no in reference to how they felt over the past week (for instance, "Do the patient feel that their life is empty?," Do the patient feel that their situation is hopeless?). Scores range from 0 to 15 with higher scores indicating more depressive symptoms.
Time frame: Change from baseline at 12 weeks
Expanded Disability Status Scale
The Expanded Disability Status Scale is the most appropriate to assess evolution and point to a new relapse. The Expanded Disability Status Scale has been the most commonly used. It has twenty items with scores ranging from 0 to 10, with the score increasing by half a point according to the patient's degree of disability, giving more focus on the patient's ability to walk (especially in scores above 4.0).
