 The study will use 20 n20 healthy volunteers. These subjects will be actively recruited from Naval Medical Center San Diego and Orthopedic by research staff. We will also use an informational flyer placed in the NMCSD Physical Therapy and Orthopedic outpatient clinic waiting room. No medical records will be used to identify subjects for recruitment. Subjects will be approached by research staff and will be asked about participation and will undergo standard practices regarding meeting, inclusion and exclusion criteria and clinical trial consent by trained research staff. Those who consent to participate will be taken to an area that houses the RMT hardware and software. Subjects will then undergo a brief 5 minute tutorial on the setup, power-on, and navigation of the hardware and gesture controlled software.
