| Zusammenfassung: | The invention relates to a device for determining the degree of mobility of the ankle applicable to the biomedical field, namely for determining the mobility of the tibial-astragalian joint in the saggital plane The device comprises a mechanical unit (A) having two rods (1 and 2) mounted on the shank and, respectively, on the foot by means of a dismountable holding system The rods (1 and 2) are joined by a movable joint (3) fastened to the leg in the region of the ankle A rotary opto-electronic transducer (B) having two semiconductor layers and consisting of a slotted disk (4) mounted on a shaft (5) attached to the joint (3), quantifies the mechanical information by means of a diode (6) and a semiconducting element (7) mounted on a wafer (8) attached to the rod The processed signal is transmitted to a digital - analogue conversion system (C) which transmits the information to a computer system (D) for data processing and display of results |
