重心動揺検査の国際基準化とわが国の問題点と今後の動向

抄録

　In 1969, the International Society of Posture and Gait Research (ISPGR) was established as an international association devoted to basic and clinical research into posture and gait. In 1983, international standards for clinical stabilometry were proposed by the ISPGR committee and published in an academic journal. These standards are widely accepted and are referred to in many countries. Japanese industrial standards for stabilometry were established in 1987, and Japanese standards for clinical stabilometry were produced by the Japanese Society for Equilibrium Research in 1988 based on the ISPGR standards. Stabilometry has been covered by the Japanese health insurance system since 1994.
　However, revised international standards were proposed at the 19th congress of the ISPGR in Bologna, and the discussions about such revisions are ongoing. In 2012, a proposed new set of standards was published in an academic journal by an Italian group. These standards were markedly different from the original ISPGR standards and the Japanese standards in terms of mechanical accuracy, precision, and sampling frequency. In 2014, a survey concerning the standardization of clinical stabilometry was carried out among the countries that have signed up to ISPGR by the informal Committee for the Standardization of Clinical Stabilometry. Recently, a French group devised another set of standards, which might become established in France. These standards are markedly different from the Japanese standards. Sudden major changes in the standards for clinical stabilometry are not considered desirable in Japan. In this paper, I would like to describe global trends in the standardization of clinical stabilometry and propose a way that Japan can deal with marked changes in international clinical stabilometry standards.
