From the desire to create a functional system for assessment and dynamic training in a sitting position, TecnoBody gave life to MF Trunk.
A product with which we at TecnoBody wanted to focus on the motor crossroads between upper, lower and upper limbs, an area of the body often lacking mobility and traumatized.
The patient sitting on the Balance Trunk system can control in real time the movement of his trunk and interact with the system thanks to constant visual feedback in real time. The applications of this intervention are numerous both in the neuromotor field, for example in cases of hemiplegia, and in the orthopedic field, in the treatment of scoliosis.



MF Trunk is a dynamic TRUNK Balance System of assessment and training in a sitting position and in getup transition, TRUNK-MF is also part of the Postural/Functional Circuit.
