Acceptability and Safety of MR-C-014 in Persons With Neuromyelitis Optica Spectrum Disorder

This is a single arm, prospective, multi-center feasibility study designed to evaluate the acceptability and safety of MR-C-014. MR-C-014 is an autonomous neurorehabilitation system based on the principles of Rhythmic Auditory Stimulation (RAS) and is designed to operate digitally and autonomously. The core mechanism of RAS is "auditory-motor entrainment." Studies have shown that there is rich connectivity between the auditory and motor systems via multiple cortical and subcortical networks. The MR-C-014 system consists of two foot sensors that measure walking, a locked touchscreen device preloaded with a proprietary software application, a headset, and charging equipment. The electronic components are powered by lithium-ion rechargeable batteries. MR-C-014 is an investigational device.
