Have you ever felt like you aren’t performing at your Best? That you just aren’t on top of your game? Opti Train will not only help you understand what an optimized performance feels like, but will teach you how to create that feeling in any area, especially when it’s most important! There are training modes for individual sports which guide you through sport-specific training routines!

Use the "Train" mode to get the same great training for performance areas not listed! ** This application requires a subscription with Opti Brain (www.myoptibrain.com) to use. Opti Train uses the Muse brain sensing headband or sunglasses to stream brain data into the app, calculate how close your brain is to a high performance brain pattern, and then outputs audio and video neurofeedback to inform you of your current state. **This application also requires an external accessory that senses your brain activity. Compatible brain sensing hardware includes: -Muse Headband -Smith Lowdown Focus Glasses powered by Muse The feedback provided by Opti Train helps you train your brain to reach an optimized performance pattern that helps you BETTER YOUR BEST® performance! Using the brain sensing headset or sunglasses, focus your thoughts to lower the volume of the feedback music or make a feedback video play. Every person’s brain looks different when they are performing at their optimum.

About

NuviCor RLX

Features
Read full description

NuviCor RLX is an application that works in conjunction with an electronic device and is designed for the user to independently solve their own cosmetic problems. NuviCor RLX implements technology aimed at deep and prolonged relaxation of facial muscles, primarily the masticatory muscles. Prolonged tension of the masticatory muscles gradually leads to the displacement of the skull bones, changes in the oval of the face, which looks like an obvious sign of aging. This is a fact generally recognized in cosmetology. The NuviCor RLX device and app implement a training-based method of autogenic muscle relaxation with hardware biofeedback. The training course consists of 30 sessions of 20 minutes each An electromyogram (EMG) sensor is placed on the patient's face, the NuviCor RLX electronic device measures the EMG of the masticatory muscles and transmits the information to the application. The NuviCor RLX application mathematically analyzes the EMG signal from the muscle, identifies muscle tone fluctuations with specified properties, and delivers motivational stimuli to the user (video files) at the moments when these fluctuations occur. Multiple repetition of unconditional (internal) and conditional (external motivational) stimuli leads to the gradual formation of a stable conditioned reflex that suppresses excessive facial muscle tension. The stability and depth of muscle relaxation are guaranteed by the effect on the cause of muscle hypertonus, namely on the brain structures that control muscle tone. The NuviCor RLX does not use any physical, vibration, electrical or electromagnetic effects on the user. The NuviCor RLX is not a medical device and is designed for muscle training at home.
