In the initial stages as with the less serious cases also, an apparative mobilisation treatment of the“friction bearing nerves” of the median nerve can be successful with the use of repeated, controlled traction movement in the wrist. Measured traction movements in different hand positions show positive effect on the afflicted symptoms in compression of the median nerve. Using this concept Contex has developed a non-powered, innovative medical traction apparatus, the PHYSTRAC GT10. Traction by this device is generated by means of gravitation. According to the Medical Device Directive 93/42/EEC annex IX, Rule 1 this product is classified into risk class I, registered with the Dutch  Competent Authority since August 1, 2005 comparable with a class 1 510(k) exempt USA according to the  Specific FDA regulations.
