Advance in measuring and loading methods of 3-dimension human spine movement.

Exact quantitative characteristic description of human spine 3-dimension motion can help to understand the pathology of spine disease and provide proper therapy and functional substitution synchronously with evaluating the effect of spine damage and surgical on spine motion correctly.The author summarized the former researching findings and expatiated on research of spine motion measuring in vitro in three aspect of spine motion measurement index,loading parameter and mode.It also gave out major outgrowth and deficiency of spine 3-dimention motion measurement and brought forward the research direction that provided reference and help on research of spine motion measurement in future.
