Introduction:
Stimulation of proprioceptors by the kinesiotherapist determines the initiation of therapy, different manual skills can be replaced with a unified, calibrated electric or magnetic stimulus.

Aim:
The aim of the study was to check whether stimulation using the motor evoked potentials (MEP) method can be used to verify the activation of the propriospinal system and as a source of stimulus in kinesiotherapy using the Vojta method.

Material and methods:
The study included 26 healthy subjects who underwent the magnetic stimulation at the acromion (ACR) on the left side and transvertebrally at C3-C4 levels. The MEPs were recorded from the biceps brachii (BB) and rectus femoris (RF) muscles using the surface electrodes (sEMG).

Results:
Parameters of 52 MEPs potentials recorded from BB bilaterally and 30 recorded from RF were analysed. Based on their frequency value, the sequence of muscles activation was calculated, which with stimulation from left ACR as well as at C3-C4 levels in a midline was as follows: left BB, right BB, right RF and left RF. Latencies of potentials after ACR stimulations were shorter in recordings from both BB and RF muscles than following the stimulation at C3-C4 level.

Conclusions:
Different fractions of the fibers in the long cervico-lumbar propriospinal system are activated following the magnetic stimulus applied at ACR via the afferent connections or only at C3-C4 cells of origin. However, they both transmit the neural signals in a velocity range characteristic for the propriospinal system.
