A two axis flexible electrogoniometer made of electroconductive rubber has been developed. The goniometer is highly flexible and does not break even if deeply deformed. Four pieces of electro conductive rubber string are plastered on a silicone rubber column of squaresection, and both ends are molded by hard plastics. A slide mechanism is constructed on one side of each end to prevent excessive deformation of the measuring part. Each pair of the two opposite sides of electroconductive rubber construct a half Wheat-stone bridge circuit to detect only the angle made by both ends of the goniometer. Two different sizes are made. The section of the measuring part is 4mm×4mm or 3mm×3mm, and its length is 150mm or 100mm. The weight of the sensing part is 10g or 5g, and the weight of the amplifier is 170g. The method of making the measuring part using a specially designed jig is described. The goniometer is calibrated to set correct bending angle separately in the directions perpendicular to each other from -90°to 90°. The nonlineality, hysteresis, and interference between the two directions are very small, and there is no necessity to compensate for clinical use. This goniometer is applied on the human wrist joint and ankle joint of a normal subject. The result is displayed in real time as the relative motion of the distal segment against the proximal segment in three-dimensional space on the CRT display. The minute phenomena of the motion can be observed, and the range of motion in the direction of dorsal, palmar, radial, and ulnar flexion of the wrist and planter, dorsal, invert, and evert flexion of the ankle can be easily grasped quantitatively.
