sEMG stands for surface electromyography. Surface indicates that the sensors are placed on, not into, the skin; in the mTrigger Biofeedback System, we use self-adhesive custom sensing electrodes. Electromyography is a process which reads the electrical activity produced in skeletal muscles during muscle movements/contractions by detecting the electric potential in muscles. This informs the signal we display and interact with in our mobile interface. See our Science section (About) or visit our Resources links (Getting Started) for more information.
At our core, we stand for providing engaging tools that enable better outcomes, empowering patients and providers, and a commitment to innovation.
FOR SYSTEM OWNERS
We don’t recommend it! The mTrigger electrodes and electrode connector cables are custom for the mTrigger system, with a special connector and features that are designed to improve signal transmission. Use of unauthorized electrodes or electrode cables not specified or sold for use with the system may result in ineffective signal transmission or cause damage to the system.
If you need smaller electrodes for a specific patient or application, the electrodes can be cut down to the appropriate size and perform as intended so long as the central plate is not damaged.
The units hold battery well and can be used for a few days without charge. All units accept micro-USB charging and the LED behind the logo will turn green to indicate a full charge. Recommended charging frequency is once per week; do not charge overnight.
First, please ensure that your unit is not resting on another electronic device or conductive surface. Due to the circuitry inside the mTrigger, some electrical noise can make its way into the system and impact the displayed signal. While this will not damage the system, it could impact the signal displayed in the app interface. Remove the device from contact with other electronic devices during use to get the best signal. If signal seems hyper-responsive or unresponsive, please force close the mTrigger app and reconnect your device.
sEMG is inherently somewhat noisey, and some signal fluctuation is expected. However, if you are seeing signals displayed that consistently do not seem responsive/appropriate to activity, please contact us and have your invoice and serial numbers on hand. We will do what we can to assess the issue remotely and determine appropriate next steps.
FOR PROSPECTIVE OWNERS
Additionally, feel free to download our setup resources, available on our Getting Started page.
Yes, we do offer a 2-week demo option for a $25 fee. You will be sent an Individual Unit kit and you will have two weeks from delivery date to use the unit and determine if it is a good fit for your practice. During this time, our support staff will be available to answer any questions you may have and help you get the ball rolling. After the two-week assessment period, you will be asked to make a purchase decision. A representative will reach out to assist you with your purchase or return. If we are unable to contact you within 30 days of your demo close date, you will be charged for the unit.
PLEASE NOTE: We will be discontinuing the demo option as of January 31, 2019. Purchases as of February 1, 2019 will offer a 30-day money back guarantee.
