Orthotic devices usually prescribed for ambulatory treatment of Legg-Perthes disease do not meet the severe kinematic requirements necessary for a comfortable gait. This paper describes the IMA II brace which offers several advantages in comparison with conventional braces. It is shown that improved kinematic characteristics are obtained by the use of six joints placed symmetrically at two levels of the brace.
通常为Legg-Perthes病的门诊治疗而开具的矫形器械无法满足舒适步态所需的严格运动学要求。本文介绍了IMA II支具,与传统支具相比,它具有若干优势。研究表明,通过在支具的两个层面上对称设置六个关节,可以获得更好的运动学特征。
