Abstract:

BACKGROUND: Reciprocating gait orthosis makes the paraplegia patients walking, but reciprocating gait orthosis can only perform walking rehabilitation training and simple walking, which was far from real walking function compensation.
OBJECTIVE: To summarize and analyze construction features, action mechanism and bionic effect of reciprocating gait orthosis.
METHODS: We retrieved PubMed Database and Wanfang Database for articles concerning features, bionic effect and clinical application of reciprocating gait orthosis published from January 1990 to December 2008. The key words were “reciprocation gait orthosis, walkabout, bionice”. A total of 32 articles were researched.
RESULTS AND CONCLUSION: At present, unpowered reciprocating gait orthosis has been extensively utilized, but it can only perform walking rehabilitation training and simple walking, which was far from real walking function compensation for paraplegia patients. The bionic effects of reciprocation gait orthosis and walkabout were poor; gait lacked fidelity; physical ability was greatly consumed. However, the gait orthosis that requires outer energy for supplement can overcome the disadvantage of unpowered gait orthosis. With the wide usage of artificial intellectual technology in robot and many industry fields, its development can provide gait orthosis that has good function, safety, reliability, and bionics.
