Functional and Quality of Life Effects of the Mollii Neuromodulatory Suit in Patients With Stroke and Multiple Sclerosis

* Objective assessment of clinical symptoms resulting from stroke, as well as changes in mobility and quality of life, and determination of changes resulting from therapies * Objective assessment of the quality of life, functionality, and clinical symptoms of patients with multiple sclerosis (MS) and determination of changes resulting from therapies * Comparison of measured data from the two main neurological patient groups (stroke, multiple sclerosis) and follow-up of changes in relation to themselves and each other. * Mapping the role of the placebo effect in neuromodulation devices by comparing subjective and objective outcomes. * Analyzing the expectations and experiences of patients receiving placebo treatment using quality of life questionnaires. * Analyzing the effects of the Mollii suit among subgroups of MS and stroke patients. * Assessing the safety, possible side effects, and tolerability of the Mollii suit. * Mapping changes in gait pattern due to the effects of therapy using 3D motion analysis. * Examining the maintenance effects of neuromodulation during a 1-month follow-up.
