General information on EMG (electromyography) biofeedback trainingThe musculature of the human being plays an essential role in the body. Our muscles are the largest energy consumer and are responsible for about 70- 80% of our body weight. Muscle activity is manifested along the fibers of a striated muscle in the form of permanent, electrical potential shifts. This electrical activity can be measured at the skin surface in the form of more considerable summation potentials. This form of measurement is called (surface) electromyography, and the result is an electromyogram. The eSense Muscle can measure and train electromyographic muscle activity and transmit it to your computer/smartphone/tablet via Bluetooth. Transverse striated muscles are controlled by our somatic nervous system and are subject to voluntary control. Every volitional action of a muscle can therefore be observed in an electromyogram. Thus, the tension of a muscle on 27 which surface EMG electrodes are placed immediately leads to increased trace in the EMG signal. However, involuntary reactions, such as stress, inner tension, and emotional experience, can also be measured as (tonic) activity in the EMG. EMG biofeedback can also report back the general psychophysiological tension. The interplay between the autonomic and somatic nervous systems can be depicted particularly well in the EMG. Increased muscle tone is mainly based on an increase in sympathetic activity. A decrease can be attributed to more robust parasympathetic activation. 11. Features of the eSense MuscleThe eSense Muscle can measure and train electromyographic muscle activity and transmit it to your computer/smartphone/tablet via Bluetooth. The eSense Muscle with the eSense App offers you:
12. The EMG signalWith EMG, we measure a voltage curve over time. We pay attention to the amplitude (the magnitude) of the signal and the frequency. Depending on the musculature, considerable differences become plain. An EMG signal from a small muscle; e.g. from a finger on the hand, is significantly lower in amplitude and frequency range than the signal from the large thigh muscle. The eSense Muscle can measure the EMG raw signal and transmit it via Bluetooth, as well as already three preset bandpass signals (RMS) in the frequency ranges: 20 Hz to 950 Hz, 20 Hz to 300 Hz and 100 Hz to 200 Hz You can select and use these in the eSense web app and the mobile app. In biofeedback, we work exclusively with these bandpass RMS signals, as these are related to amplitude and applied muscle force. The amplitude ranges from a few µV (millionths of a volt) to several hundred µV in particularly strong muscles. The frequency range of the EMG signal does not play a significant role in EMG biofeedback. It only emphasizes the signal part you want to look at. EMG activity has a broad frequency spectrum, from 10 Hz to 500 Hz, focusing between 25 and 300 Hz. Choose a wide filter (20-950 Hz) if you want to capture and feedback all components in the EMG and choose a narrow filter (100-200 Hz) if you’re going to capture the majority and filter out possible sources of interference such as pulse artifacts or mains hum. It is advisable to always choose the narrowest filter (100-200 Hz) first and to check whether the measured signal is represented sufficiently well with it. The filter should only be widened and set wider if the amplitude appears too small and not very reactive. 13. Introduction to eSense MuscleTo reduce stress and its vegetative symptoms, an EMG biofeedback training can be performed by causing a reducing the muscle tone of certain “stress muscles” is aimed at. Typical stress muscles are the muscles of the forehead (M.Frontali), the jaw muscles (M.Masseter) and the shoulder muscles (M. Trapezius). Examples of possible EMG measurements:   Through exercises that involve targeted tensing and relaxing (similar to the progressive muscle relaxation) these muscles can be lowered in their basic tone and thus reduce stress. For muscle building and strengthening individual muscles or muscle groups, a variety of possible derivations can be used. The electrodes of a channel are placed closer to each other, the more precisely the underlying muscle is recorded. With increasing distance you reach the activity of larger muscle groups. During training you, then muscle tone increase maximum values and improve endurance. For this purpose, tension phases with progressive training being prolonged and increased. Pay attention however also make sure to always incorporate sufficient rest phases. For coordination exercises and targeted separation of muscle groups (e.g. lifting the arm without “pulling up” the shoulder), channel 1 and channel 2 can be cleverly combined. For example, channel 1 can be applied to the muscle that is to be tensed, while channel 2 can be applied to an adjacent muscle. Muscle to be tensed, while channel 2 “monitors” an adjacent muscle so that is not tensed during the movement. Each muscle movement generates a characteristic pattern under an EMG measurement, which is pattern, which can be practiced and repeated in the software. The possibilities of using EMG biofeedback are very diverse. Let a professional user assist you in this regard if you have any questions. Important: If you are suffering from a medical condition, do not perform a treatment on your own and always consult a therapist. The eSense Muscle is not a medical device and may be used exclusively for stress reduction, muscle building, relaxation of tension and for coordination exercises to be used! 14. ProceduresA procedure consists of different modules. The procedures can be used, for example, to implement instructions for relaxation, a stress test, a defined biofeedback training session or tasks for research purposes. The possibilities are manifold. During a procedure, your this electromyographic activity is recorded. At the end of a procedure, a summary is displayed, showing your readings for each module and the overall view.  We recommend that you try the demo procedures included in the app. These give you a guided overview of the different modules and functions. The included procedures are also protected by a password in order that those can’t be edited or deleted by accident. You can any time create a copy of those procedures without a password and change it as you wish. We also explain in detail how you can create and edit your own procedures in the chapter procedures settings. 15. Open TrainingAs a second option, you can also do free training. This differs from the procedures in that it is a little more complex. In the following we give you a few examples of how EMG biofeedback training with the eSense Muscle could look in different applications. Please consider this only as a rough guide. There are a variety of options, this is just a brief overview. There is a lot of literature on the subject of EMG biofeedback, which gives further assistance on how to proceed. Preparation and start

16. Cleaning and CareFor cleaning and care, there are the following essential tips:
17. Adapter for Android and Apple devicesSome newer Android and iOS (Apple) devices without the classic 3.5mm headphone jack and with the newer Lightning / USB-C connector also work perfectly with the eSense. AppleYou either need an original Apple USB-C (https://amzn.to/2OQYssu) or original Apple Lightning (https://amzn.to/2SJVg37) to 3.5 mm connection adapter (not included in the scope of delivery of the eSense).  has a 3.5mm headphone jack, e.g. the iPhone X.) Android & AppleAlternatively, you also can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1  An adapter is also only needed, if at all, for the eSense Skin Response, eSense Temperature and eSense Respiration (as these eSenses have a 3.5mm headphone jack). An adapter is never needed for the eSense Pulse and eSense Muscle (as these connect to the device wirelessly via Bluetooth). 18. Notes before starting the eSense Mobile App The Pro Edition of the eSense Muscle includes the eSense Mobile App. It offers a wealth of features for effective biofeedback training in a modern design. The app is available in English, German, Spanish, French, Italian, Portuguese, Ukrainian, Russian, Turkish, Dutch, Japanese and Chinese. The language is chosen automatically according to the set language of the smartphone or tablet. In the following course of the manual we will now go into the use of the mobile app. For an explanation of the use of the web app, please watch the videos at www.mindfield-esense.com. Many of the instructions on how to proceed are congruent between the mobile app and the web app. Therefore, please always make yourself fully familiar with this manual, it conveys a lot of knowledge for a successful use of the eSense Muscle, regardless of the software application. There is also no cloud connection for the eSense Muscle. The creation of an account does not bring any advantages for the use of the eSense Muscle. Download Links  iOS: https://itunes.apple.com/us/app/mindfield-esense/id1141032160?mt=8 Android: https://play.google.com/store/apps/details?id=com.mindfield.boisystem.esense 19. Preparation and start of the eSense Mobile AppCreate the conditions needed for a successful training:
Strong physical activity before measurement should be avoided. In order to obtain comparable measurements, you should always train under the same conditions . The number of sessions required for reliable success is relatively small compared to other biofeedback training sessions. Usually, six to ten sessions are sufficient. As far as the duration of a session is concerned, it depends on your ability to concentrate, but should not exceed 30 minutes. If you are experiencing severe fatigue, the training should be shorter and a higher number of sessions should be done. The next step is to start the app. Home Screens   First tap on the logo of the eSense you want to use (here eSense Muscle) and then choose between procedures or free training. At the beginning you can choose between a free training and a procedure. We recommend that you start with a procedure 20. General notes

22. Contraction Helper You can activate the contraction aid in the general settings. Tension and relax your muscle as the sphere expand. With growing sphere tension, with shrinking sphere relax. 23. Survey (optional)If you have activated this option in the general settings, a small survey will appear immediately after each measurement. This allows you to archive measurements that are reproducible in the long term or to document a change in your measurements. (If you for example start to use the eSense while lying down instead of sitting down).  Your position during measurement How do you feel? Note function, optional 24. Analysis (after the measurement)After the measurement (and optional questioning), in landscape format, a screen appears with an analysis: the measurement duration, the filter used, the refresh interval and the lost packets in percent. In addition, the minimum and maximum values of the channel(s) are displayed. At this point, you can also swipe the screen to the left or right to switch between the analysis and the graph of the measurement.  25. Procedure Overview Edit or delete procedure To edit a procedure, simply swipe it to the left in the overview. You can then tap the blue pen-symbol to edit the module. If you want to copy the procedure, tap on the green copy-symbol. By touching the red trash symbol, you can delete the module. 26.

Own media (photos, videos and audios)You can use your own pictures in the picture module, your own videos in the video module or your own music or melodies in the audio module in the procedures. Android usually enables this without any further problems. As long as you allow the eSense app to access your files on your device, you can upload them to the eSense app. iOS is a bit more restrictive. As usual, you can use your pictures from your device in the iCloud for pictures and videos. For audio files you need iTunes (or an alternative such as “CopyTrans Manager”). This is where your music or melody must be. You can find your music in iTunes (or CopyTrans Manager) under the tab “My Sound” and insert it into your procedures. We have a detailed video at https://www.youtube.com/watch?v=A_CRbmBeBBc where we show all the steps. On iOS the power saving mode must also be deactivated, otherwise the videos in the procedures cannot be played. 31.

32. In App Purchases In-App Purchases 33. Archive (overview) The app also contains an archive, in which you can save your measurements and export them as well. You can watch those in detail again, compare them to each other and export them individual or all together (as ZIP file). Recordings If you click on the clipboard symbol at the top right, you can mark one, several or all measurements. You can then export, analyze or delete the exported measurement (s). On the filter symbol you can choose whether you want to sort the measurements by name, date, length in ascending or descending order. If you want to delete a single measurement from this list, you can also tap on the trash can symbol to the right of the measurement.  Analyze Time, score, average of session HR, minimum HR, maximum HR, difference min/max HR, SDNN ms, RMSSD ms, NN50, pNN50 %, stress index, average RR ms, Average HR. With this, you can recognize trends over time and over several measurements (if, for example, your % of SCR of Session decreases by regular training, you can see this here immediately). 34. Archive (single view) Export data If you click on the export symbol on the top right, you can export the measurements as a .csv-file with all common apps (for instance, send over the Messenger, WhatsApp, email, etc.) or simply save them on your device or in your cloud. The data are exported as a.csv-file (comma separated values). This format can be opened with Microsoft Excel or Open Office Calc (for free). If you like to work with Google, Google Sheets can be an alternative to Excel for you. You can open your exported .csv-files, visualize and access them via the cloud easily from several devices. Google Sheets has almost the same functions and interface as Excel. Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data.   In Excel™ or Google Sheets™ Notice: If you open the .csv-file with Excel™ (or Google Sheets™) and your values make no sense, then there is usually a different set language in the eSense App and Excel™ and Sheets™. Note: We have also summarized more detailed information on CSV export and processing your data in an extra article on streaming and analyzing eSense data.  35. Marker featureYou can also set markers while you make measurements. For example, if you have a regular biofeedback exercise which involves breathing calmly at a specific point, you can set a marker in that moment when you breathe calmly. Later in the exported data, you can see the moment where you had breathed calmly. The marker feature comes in handy when you are making longer measurements with several actions. The markers can be displayed well in Excel:  36. Compatible Android and iOS devicesGeneralNote for all eSense: If you don’t have a device yet and/or want to buy an extra device for the eSense, we recommend depending on your taste either

You do not need to install any software. All you need is:
We recommend that you use the latest version of Google Chrome. Mozilla Firefox and Apple’s Safari are NOT SUPPORTED! So, if you have a computer with Bluetooth and one of the mentioned browsers, please go to the website: https://esense-muscle.comYou can then launch the web application on this web page and get further instructions on how to use it (please watch the instruction video). You then connect directly to the (switched on) eSense Muscle via Bluetooth in your web browser.You are offered different representations of the measurement (oscilloscope, different animations, different games, etc.) We update the eSense Muscle Web App regularly. You are offered different representations of the measurement (oscilloscope, different animations, different games, etc.) We update the eSense Muscle Web App regularly. Mindfield eSense Web App for mobile devices (Android or iOS)For the first time, the eSense Muscle comes with new software—a web app that runs exclusively in a web browser. This is also usable for mobile devices, but we recommend using the Mindfield eSense Mobile App once it supports the eSense Muscle. To use the web app on mobile devices (smartphones or tablets), you need:
On Android, you need to use “Google Chrome” for this. On iOS, Web Bluetooth is not supported by Safari. You need to download the app “eSense Muscle” from the Apple App Store, a minimal browser that supports Web Bluetooth. It will take you directly to our website after the start: iOS: https://apps.apple.com/app/esense-muscle/id1563762101 If you are using Google Chrome on Android or the “eSense Muscle” app on iOS, please navigate to: https://esense-muscle.comYou can then launch the web application on this web page and get further instructions on how to use it (please watch the instruction video). You will then connect directly to the (switched on) eSense Muscle via Bluetooth in your Chrome browser on Android or the “eSense Muscle” browser app on iOS. You are offered different representations of the measurement (oscilloscope, different animations, different games, etc.). We update the eSense Muscle Web App regularly. We recommend using the desktop version of the eSense Web App with a desktop PC, notebook with Windows, Mac or Linux. The mobile version of the web app comes with reduced content due to technical reasons. 39. Account and CloudYou can register your own, free account for the eSense app and book plans. You can also benefit from free, regularly added procedures without booking a plan. Thus, we recommend using the app with an account. With the plans you can mainly use the cloud and its functions and get also access to the eSense web app at https://esense.live. With the Basic plan, you can save your measurements locally and online in the cloud and thus access your measurements from all devices and from anywhere. You also get access to the eSense web app. The Premium Plan includes all functions of the Basis Plan. In addition to your measurements, you can also save your custom procedures online in the cloud and thus access your procedures from all devices. (Attention: Technical limitations from Apple unfortunately do not allow the upload (and thus the synchronization) of audio files. The synchronization of picture and video files is possible, however). You can also share your measurements with other users as Premium plan user. You also have the option to live stream your data to the eSense Web App in real time. To do this, activate “Real-time data transfer to eSense Web App” in the settings at the bottom. These plans can be used, among other things, to design a trainer’s client’s workflow. You can find an overview of the account and the cloud in our account comparison article. You can book the plans in our app in the profile tab:   Plans in profile tab 40. GroupsThe accounts enable you to create your own groups or to join other groups. This allows you to share your recordings with your friends. Or you can work with a trainer as a client since you can share your recordings with the trainer.  Create a group Tap on the plus symbol to create a group. Edit a group Tap on the 3 dots next to the group name You can then (if authorized) view and remove the members of the group or add new members. 41. Privacy policyThe eSense App does not collect any personal data, such as name, gender, date of birth, etc.. Each recording of measurement data is done under a general prefix such as “measurement”, supplemented by with the eSense sensor used, the current date and time of the measurement. The recorded measurement data cannot therefore be assigned to any person. The prefix of a recording, e.g. “measurement”, can be changed by the user in the settings and used for the assignment to a person. Users can decide whether to change this prefix to their name, for example. Then each measurement and also each CSV file exported from it contains the name of the user in the file name.
