Mindfield® eSense Muscle | Assess muscle tone
Assess muscle tone with the eSense Muscle
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 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. Assess muscle tone with the eSense Muscle is therefore very precise and simple at the same time. 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. This biofeedback for stress and relaxation is very important so that you can train your body and thus actively reduce stress levels.Assess muscle tension – get biofeedback on stress
With the eSense Muscle you can find out how stressed your body is. Using electromyography (EMG), you can assess your muscle tone and thus get an accurate picture of your state of tension. You receive direct biofeedback during relaxation and stress.
The eSense Muscle is therefore the optimal device for a user-friendly measurement of body tension. You do not need any medical knowledge or skills to get biofeedback during stress. But you can also read and recognise biofeedback during relaxation without any problems via your mobile device.
The instant biofeedback of the eSense Muscle allows you to control and reduce your body tension. In real time, the muscle tone is assessed and you can follow the biofeedback via the screen of your smartphone. You can recognise stress by a higher body tension, a low muscle activity indicates that you are relaxed. Biofeedback on relaxation is very valuable for your everyday life and stress management. Assessing muscle tone has never been so easy and effective.
There are also other devices, such as the eSense Skin Response, which allows you to measure your skin resistance and detect your stress level.
Muscle relaxation – muscle biofeedback
The eSense Muscle can also help you loosen your muscles. Simply connect the device to a tense part of your body to read the muscle tone. The biofeedback gives you information about your muscle activity, so you can specifically improve your relaxation techniques and see if certain exercises have led to a loosening of the muscles.
This can be very helpful for rehabilitation, especially after sports injuries or accidents. You can also use your body tension during a muscle loosening exercise and thus check whether a muscle has come to rest or not. In this way, you can specifically reduce tension and optimise your rehabilitation process.
The eSense Muscle is the perfect tool to assess body tone, prevent pain and detect stress in the muscles!
