The GM-REHAB-2025 study aims to evaluate the impact of physiotherapy interventions using the C-Mill treadmill, with and without semi-immersive virtual reality, on gut microbiota and metabolic parameters in patients with Parkinson\'s disease. Three groups will be involved: one undergoing conventional physiotherapy, one treated with the C-Mill without virtual reality (VR), and one treated with C-Mill technology combined with VR. Clinical assessments and the collection of biological samples (stool, serum, and plasma) will be carried out at three time points: at baseline, at the end of treatment (21 days), and after 3 months.
