An ambulatory monitoring system constructed from an instrumented pylon, a flexible electrogoniometer and a minicomputer for data processing was improved. Newly developed strain-gauged flexible electrogoniometers and foot switches made of pressure-sensitive electroconductive cloth were added to the system, and the minicomputer for data sampling and processing was replaced with a microcomputer. The whole system can move anywhere with a subject to measure various functions of the artificial leg continuously for long periods under any walking conditions. With this monitoring system, some dynamic functions of the foot-ankle units of A/K prostheses were measured and evaluated. The quantitative relations between bending moment and flexion angle in the sagittal plane were examined. The compliance of the heel bumper was set on five different levels by an adjustable screw. At each level of the compliance, two A/K amputees were measured during level and stairway walking. Each amputee is fitted with a prosthesis consisting of a total contact suction socket, single axis knee joint and single axis foot-ankle unit. Minute information about the dynamic behavior of the prosthetic foot-ankle unit was attained which could not be obtained by previous studies.
