Evaluating a New Sensor That Measures the Health of the Retina in Normally-sighted Subjects

The primary purpose of this study is to evaluate the ability of a new contact lens electrode to record a measurable electroretinogram (ERG). ERG sensors in various forms have been in common clinical use for more than 50 years. The ERG sensor that is the subject of this study is the RM Electrode, developed by RetMap, Inc. (project sponsor). The RM Electrode is not yet approved by the FDA. The RM Electrode will be compared to other commercially available electrode The first Aim of the present study is to compare the functionality of the RM Electrode and other commercially available electrodes. Following standard ERG test protocols, responses will be recorded from ten healthy (normally-sighted) adult subjects using both electrodes (used in random order). The signal quality of the ERG responses obtained from both contact lens electrodes will be compared. Signal quality will be determined by measuring ERG signal amplitudes and calculating signal-to-noise ratios (SNR). Signal-to-noise ratios will be used to establish substantial equivalence. ERG test results will not be used to determine the effect of the devices on the participants. The second Aim of the present study is to evaluate the risk of ocular irritation caused by use of the RM Electrode compared to other commercially available electrodes. A typical ERG test session lasts 20 minutes. Ten healthy (normally-sighted) adult subjects will wear the RM Electrode on one eye and a commercially available electrode on the other eye, for a total of 60 minutes, in 20-minute sessions with short breaks in between. To determine the effect of the devices on the participants, the eyes will be evaluated for irritation.

Functional Electrostimulation on the Upper Lip in Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune disease where immune cells attack the body, triggering an inflammatory response. A study comparing multifield FES and conventional FES on upper extremity motor skills and functional independence in MS patients will be conducted. Results suggest that both types of FES treatments normalize muscle tone, showing superior results compared to those without FES therapy. The study aims to compare the effects of both types on MS patients.
