3、aldensity.脊髓损伤是指损伤脊髓而导致损伤平面以下活动能力和感觉的丧失。大多数患者借用各类矫形器站立和行走。Y有人认为，配戴矫形器直立和走路可减少骨质疏松，改善关节活动度，并减少肌肉痉挛。然而，关于行走和站立对骨密度的临床效果存在差异。Theaimofthisresearchwastofindtheabsolutevaluesoftheloadstransmittedbybodyandorthosisinwalkingwithuseofanorthosis.5normalsubjectswererecruite

5、：通过解剖结构得到的数据比矫形器得到的数据更有意义。此外，该矫形器和身体的力和力矩模式彼此完全不同。在配戴矫形器行走的过程中，携带矫形器行走能够影响骨密度是由于大部分的载荷通过解剖结构进行综合的传递。Ithasbeenshownthattheloadsappliedontheanatomyweresignificantlymorethanthattransmittedthroughtheorthosis.Moreover,thepatternsoftheforcesandmomentsoftheorthosisandb
