CON-TREX® TP is a special back module, ideal for the testing and training of straight trunk musculature with its flexor and extensor muscles. It is connected to the CON-TREX® MJ system, the measuring range of version TP 500 being designed for rehabilitation and leisure, with the TP 1000 being more suited to top-level competitive sport (TP 500 and TP 1000 only differ in their torque range, maximum torque 1000 Nm).

The many customisation options, easy positioning and numerous different load types of CON-TREX® human kinetics software make possible various testing and therapeutic applications of the trunk.

Together with the various load modes operated by the PM control module, the freely definable scope of motion in the range between -15° and +105° enables the therapeutic handling of numerous problems related to longitudinally-running trunk musculature.

The height of both the footplates and knee rests can be electronically adjusted to facilitate easier positioning of the patient. The kneerests are synchronised with the footplates. Just one finger is all it takes to easily change the position of even those heavier-set patients already standing in the machine.

The dynamometer technology of CON-TREX® guarantees previously unequalled precision and sets new benchmarks when it comes providing quality in diagnostic and therapeutic work. It works free from backlash and with a 100% digitally controlled drive system. The controls are optimised to be simple in usage and easy to clean, while making sure that the risk of injury is kept to a minimum. The entire drive and control system can be adapted at any time to future trends in physiotherapy thanks to the easy software upgrade and smoothly updated to the latest computer technologies.

In its ballistic mode, CON-TREX® has a one-of-a-kind control system. Here, in order to compensate for the inertia of moving body parts, the expected motional development is calculated beforehand and the generated “inner strength” is continuously equalised. To this user this means the following: the motion can be executed functionally, realistically and for a longer period at the desired target speed – particularly with minimal effort, at high motion speeds or when large body segments are being moved. CON-TREX®’s ballistic mode enables both isokinetic and isotonic work.

Another advantage is the active compensation for gravitational force during training and diagnosis. Patients with little strength are often unable to move individual segments of their bodies without assistance. This means that active compensation for these static weight influences is required. While the movement is being performed, the dynamometer can continuously reduce the external forces or even compensate them completely; this produces a “gravity-free”’ situation for the patient where every movement can be performed with minimal expenditure of force.

CON-TREX® software also offers the option of merely measuring the forces acting on the movement, without active compensation. When evaluating data, the measured values can then be displayed as “gravity-corrected”.
