A Study on the Adduction and Abduction Measurement of Children with Spastic Cerebral Palsy for the Development of Multi-axial Lower Extremity Orthosis

In the present study. the design of multi-axial lower extremity orthosis was presented with adduction and abduction force data which were measured from three children with cerebral palsy and a normal child. The measurements of adduction and abduction forces were conducted in standing and wolking condition. Adduction and abduction forces were measured by strain gages which were attached on the lateral uprights of lower extremity orthoses. In the standing condition. addcution force of childrens was distributed from 0.11 kgf to 0.26 kgf. During the walking condition. adduction force was reached to 1.56 kgf and abduction force was reached to 1.52 kgf.

경직성 뇌성마비 소아의 다축 하지 보조기 설계를 위한 내.외전력 측정

다축 하지 보조기의 설계는 정확한 내$.$외전력의 측정이 필요하다. 내$.$외전력 측정을 위해 정상아동과 장애아동들의 실험을 통해 내$.$외전력을 측정하였다. 내$.$외전력의 측정은 정지상태와 보행상태에서 측정되었으며, 다축하지 보조기의 측방지주에 장착된 변형률 게이지를 이용하여 측정하였다. 정지상태에서 경직성 뇌성마비 아동은 0.11 kgf부터 0.26 kgf까지 내전력만 나타났으나 보행상태에서 1.56 kgf의 내전력과 1.52 kgf의 외전력이 작용됨을 알 수 있었다.
