Quick User Guide


  • Take the electrode cable set from the package. Five electrode cables are included. In black, white, yellow, red and green.
  • The yellow electrode cable is the ground / earthing electrode.
  • For a 1-channel measurement, please use the electrodes black (channel 1+), white (channel 1-) and yellow (grounding).
  • For a 2-channel measurement, please use the electrodes black (channel 1+), white (channel 1-), yellow (grounding), red (channel 2+) and green (channel 2-).

  • Two examples for a 1-channel measurement:
  • An example of a 2-channel measurement:

  • Clean the skin areas where you want to place the electrodes with the enclosed alcohol swabs or isopropyl alcohol.
  • Take the appropriate number of EMG surface electrodes from the enclosed package. Clip the electrodes to the cable ends before placing them on cleansed skin.
  • Remove the protective film from the electrodes and stick them to the cleaned skin. If you have not already done so, plug the electrode cables into the matching colored sockets on the eSense Muscle.
  • Now the eSense Muscle is ready for use and connected to the eSense (web) app.

General information on EMG (electromyography) biofeedback training

 

  The 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 mobile device, tablet or computer 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.

Short version of an EMG biofeedback training

.

To 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).

Specific muscle relaxation exercises can help to reduce the muscle tone of stress muscles. The electrodes are placed so that they can accurately measure the muscle. The closer the electrodes are to each other, the more accurate the measurement.

For muscle building and strengthening, various leads can be used. The closer the electrodes are to each other, the more accurate the measurement of the muscle. Larger muscle groups are measured with increasing distance.

During training, the muscle tone is increased, maximum values are increased, and endurance is improved. The tension phases are extended and strengthened with increasing training. It is important to also include sufficient rest periods.

Channel 1 and channel 2 can be cleverly combined for coordination exercises and targeted separation of muscle groups. For example, channel 1 can be placed on the muscle to be tensed, while channel 2 "monitors" a neighboring muscle so that it is not tensed during movement.

EMG biofeedback training offers a variety of possibilities for stress reduction, muscle building, and coordination exercises.

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.
