Summary

This study is a randomised controlled trial designed to thoroughly investigate the effects of aerobic exercise on NVU biomarkers in individuals with MS. The study was conducted between February and June 2025 at the MS clinic affiliated with the Department of Neurology, Faculty of Medicine, Ondokuz Mayıs University. Participants were randomly assigned to either a control group or an exercise group. Assessments were conducted at baseline (pre-assessment) and eight weeks after the intervention (post-assessment).

Detailed description

In multiple sclerosis (MS), impairments occur in many of the cell types involved in the functioning of the Neurovascular Unit (NVU). The study examined the relationship between aerobic exercise and biomarkers associated with NVU function in individuals with MS, including Neurofilament Light Chain (NfL), Vascular Endothelial Growth Factor (VEGF), Glial Fibrillary Acidic Protein (GFAP), and the effects of aerobic exercise on the 6-Minute Walk Test (6MWT), Timed Up and Go Test (TUG), and 9-Hole Peg Test (9HPT), which determine clinical progression. Methods: Thirty RRMS patients with a confirmed diagnosis of MS who met the inclusion criteria were included in the study. Patients who scored 24 points or higher on the Standardised Mini Mental Test (SMMT) and had an EDSS score between 0 and 4 underwent pre-testing, which included a demographic data form, 6 DWT, TWT, and 9 DPT. Blood samples were collected for analysis of NfL, VEGF, and GFAP biomarkers. Patients were randomly assigned to either the control or exercise group, and the exercise group underwent an aerobic exercise programme for 8 weeks. After the exercise programme, all patients underwent the 6 DYT, ZKYT, and 9 DPT as a post-test, and blood samples were collected.

Interventions

Type	Name	Description
OTHER	aerobic exercise intervention	The aerobic exercise programme was implemented over a total of 8 weeks, with two sessions per week, using a treadmill under the supervision of a specialist physiotherapist. Patients' functional capacities were determined by estimating VO2 peak using walking distance, heart rate, and blood pressure measured at 6 DYT. During the aerobic exercise programme, patients' heart rates and oxygen saturation levels were monitored using a pulse oximeter, and care was taken to ensure that the Borg Scale value perceived by patients was between 11 and 14. After the aerobic exercise programme ended, heart rate, blood pressure, and Borg Scale were monitored for at least 5 minutes until they returned to baseline values. The session duration was planned in accordance with the literature, consisting of three phases: a warm-up phase, a loading phase, and a cool-down phase, lasting a minimum of 30 minutes and a maximum of 40 minutes.
