We have developed new type of walking orthosis for paraplegics named "HALO". The HALO orthosis has a linking mechanism that connect both ankle joints with a medial single hip joint. This orthosis allows users to keep both feet always parallel to the floor while walking, and assists the swinging of the leg when the contralateral ankle is flexed dorsally by loading. To evaluates this orthosis, we performed gait analysis useing 3-dimensional motion analysis system and force platforms and compared with previous type of orthosis for paraplegics. The results of analysis showed that HALO orthosis gives stability in walking and utilise the dorsiflexion moment of ankle to assist the swing of the contralateral leg. However, there is the usage of the better dorsiflexion moment, and further improvement has been left.
