Balance Trunk system offers a very sensitive multi-axial platform capable of detecting movements of the pelvis in an antero-posterior and right-left direction. The stability of the system is adjustable by the operator in relation to the patient's proprioceptive abilities from a minimum level of 1 (maximum instability) to a maximum of 30 (maximum stability). Thanks to the flexibility of adjusting the platform, you will be able to make your patient work on the mobility of the pelvis, correlating the work to the mobility of the lumbar area, acting on limitations at both the joint and muscular level.
