• high-precision isokinetic mode • ballistic mode • active compensation of gravity • unique combined load types • precise and very close adjustment of the rotary axis of the dynamometer in relation to the joint axis • The system includes a 3-level safety system based on mechanic and software-controlled mechanism. • Software features: o the system allows for easy setup of patient or anonymous subjects. The software should automatically apply test or training protocol used from the most recent session. o The software should allow for active compensation of gravity in the total movement pattern to compensate weight of limb and adapter during measurement
