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.
