Abstract
Abstract In this study, three knee-orthoses (dial lock type, medium size, right side) were used for a quality level test (static bending test and solidity test of the locking system) of the knee-orthosis locking system. In the static bending test, a smaller maximum load was observed in samples A and C compared to the reference standard value(KS P 8408 standard value: 1000 N, sample A: 865 N, sample C: 833 N). In addition, in the solidity test of thelocking system, a smaller maximum load was observed in the all samples compared to the referenced standard value(KS P 8411 standard value: 200 N, sample A: 41 N, sample B: 97 N, sample C: 54 N). Korean industrial standardsfor knee-orthoses and systematic test methods are lacking. Therefore, a systematic management plan for knee-orthosesis required. The result of the current study showed that a systematic management plan for the knee-orthosis lockingsystem is required. In particular, the development of a quantitative and objective test method is needed. The findingsof the current study may be useful for monitoring the quality of the knee-orthosis locking system and may providefoundational information for the development of a quantitative and objective test method.
