Outline of Final Research Achievements

We investigated knee function, physical function, and physical activity after TKA over a long period of time, examined items related to an increase in physical activity, and examined the effects of draw-in walking using an intervention study. As a result, significant increases were observed in the number of steps and all hours of low-intensity and medium- to high-intensity activity at both 6 months and 1 year after TKA compared with those before TKA. The group with diabetes mellitus was significantly lower than the group without diabetes mellitus at any time. Items related to physical activity after TKA were knee extensor strength before TKA and physical activity before TKA. In addition, continuation of draw-in walking for 3 months improved health-related QOL, exercise self-efficacy, waist circumference, blood test data, and trunk muscle mass, and the implementation rate was high.

Academic Significance and Societal Importance of the Research Achievements

観察研究で，糖尿病が併存するTKA患者の実際の身体活動量・膝機能・身体機能の経過を調査し，身体活動量に関連する項目を明らかにすることで，現状を把握でき，適切な介入方法を検討できる．また，運動でも工夫をすることによってたった1種類であっても効果があることを証明することで，糖尿病が併存するTKA後患者が地域社会に帰った際に，誰でも簡単に指導でき，継続しやすいという利点を生かして，2大疾患の重症化予防が大幅に進むことが期待できる．
