EMF & EMS
The application of electric and magnetic fields outside of medicine has expanded significantly. Both nerve and muscle cells are stimulated by external fields, for example, to improve cognitive abilities or induce targeted muscle contractions.
Electrical muscle stimulation has established itself as a new training method, particularly in the fitness sector, and is increasingly being offered.
For the devices used in this field, such as low-frequency, direct current, and magnetic field devices, there are internationally recommended exposure limits (ICNIRP 2009, 2010) that ensure protection against acute health effects. Exceeding these limits may result in side effects if used improperly or if contraindications are not known. The basic effect of these devices is the irritation of nerves and muscles as a result of the additional electrical fields generated in the body. Muscle stimulation can cause muscle pain and damage if the irritation is too strong for the person being treated. In extreme cases, even muscle death and disintegration is possible.
When muscles are overloaded, the concentrations of certain proteins in the blood rise, which can lead to kidney damage. The physical characteristics of the person being treated must also be taken into account. For example, small and petite individuals are always subject to greater stress than tall and strong individuals.
Untrained muscle cells also react more sensitively to the same stimulation than trained ones. Therefore, untrained individuals can be damaged more quickly and severely.
In order to exclude risks as far as possible, the NiSV sets out requirements regarding the qualification of persons who use non-ionizing radiation sources (expertise).
