[Development of biologic report systems for prostheses and ortheses (author's transl)].

By linkage with the physiologic sensory nervous system we have tried to open up information channels for reporting back states of prostheses and ortheses. Wired surface- and subcutaneous electrodes are used. Stable and conductive contact has been observed up to 1 1/2 years. Detachment is secured but quantitative allocation to certain sensory processes is not yet possible. Future work with improved technical means and using correlation analysis is required.
