## Indications for use
WIEMSPRO is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. The WIEMSPRO is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. None of WIEMSPRO training programs is designed for injured or ailing muscles and its use on such muscles is contraindicated. WIEMSPRO is a machine with electronic muscle stimulation based on EMS technology. Regarding its use, the device is specifically designed as an addition to other sports and for training muscles. It must be used for only healthy muscles and clients, not for rehabilitation purposes. WIEMSPRO electrical impulses allow the triggering of action potentials on motoneurones of motor nerves (excitations). These excitations of motoneurones are transmitted to the muscle fibers via the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, total session duration), different types of muscle work can be imposed on the stimulated muscles.
