The heart of the system
The heart of Pro-Kin system type B is managed by a sophisticated electric-pneumatic  rear actuated  loop.
 The compressed air introduced into the system, thanks to a electronic regulator,  allows a fluid and precise movement of the platform.
The instability levels of the system are 50. The levels from 1 to 10, very soft, allow an exercise also with the monopodalic formality. The levels from 1 to 50 are ideals for a very gradual bipodalic proprioceptive training.
