PRIMA ISO • PRIMA PLUS – Multi-Joint isokinetic system

Isokinetics is an essential methodology in modern rehabilitation practice. The knowledge of the advantages and the limits associated with this method, combined with the long experience acquired working with users, has allowed the creation of the PRIMA ISO.
This is a compact, user-friendly, cost-effective unit, developed to optimise the advantages of isokinetic method. The PRIMA ISO utilises a hydraulic brake to improve the movement fluidity while ensuring the patient’s complete safety.
The dynamometric brake is integrated in the seat support structure for maximum compactness. The control console is designed to house a small accessory basket. The PRIMA ISO is a complete system for rehabilitation, training and evaluation. All measured data can be displayed in real time and saved for post-processing. The completely new software, developed with new technologies for Windows™, is user-friendly and provides an amusing video game designed to enhance the patient’s motivation.
The programmable software ensures maximum safety for the patient (the range of motion can be limited at any point of the movement either by mechanical stops or via software setting). The system allows storage and printing of comprehensive modular final reports via simple operations.
With the PRIMA PLUS, furthermore, there is the possibility to have an active function of the machine.
