Outline of Final Research Achievements

I designed a tiptoe, the inside, the outside, the smart insole which inserted a pressure sensor in four places of the heel and developed it. I aimed at there being early detection of sarcopenia and the local people motive syndrome by analyzing the diachronic load pressure data every part when I walked in the shoes which inserted this insole and studied it.
I analyzed a walk in a physically unimpaired person, orthopedics of each age over time in various groups such as degenerative gonarthrosis, a patient, an athlete or a patient after the skill in sports injury who had a diagnosis of hips spinal column stenosis.
I was able to estimate the detection, the stage of a disease of patients with degenerative gonarthrosis by betting these data on machine learning.

Academic Significance and Societal Importance of the Research Achievements

75~79歳では男女ともに約2割、80歳以上では男性の約3割、女性の約半数がサルコペニアに該当し、サルコペニアになると死亡、要介護化のリスクがいずれも約2倍高まると言われている。そのため、サルコペニアを早期発見し、運動や食事などの生活習慣の改善等によって、その進行を食い止めることは健康寿命の延伸につながる。
靴は家の中以外では自然と身に着け、外出時にはほぼ装着したままであり、日常生活の中での生体データを抵抗なく採取するのに有用なツールである。そこに注目し、靴の中に挿入できるインソールデバイスから早期にサルコペニアを検出し、対象者に早期介入することにより、健康寿命を延伸する。
