Outline of Annual Research Achievements

By dissecting formalin-fixed cadavers, the mechanical and morphological properties of the hamstrings muscles and aponeuroses have been investigated.
1. Differential effects of formalin fixation on cadaveric muscles and aponeuroses were investigated;
2. Reliability and validity of the myotonometer in cadaveric studies were examined;
3. Morphological distribution characteristics of hamstrings aponeuroses were measured.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

The morphology and mechanical properties of the aponeuroses of the hamstrings has been conducted smoothly, and the samples and data were collected according to the schedule of cadaveric research at Aichi Medical University.

Strategy for Future Research Activity

The morphological and mechanical properties of the aponeuroses of the quadriceps muscle will be further studied. In addition, the fiber orientation of the aponeurosis tissue will be further investigated to find the relationship between the aponeurosis and the susceptibility to strain-injury.

Causes of Carryover

次年度使用額が生じた理由として、コロナ感染拡大のため、当初予定していた旅費を使用できませんでした。昨年の予算から約32万円が残っています。
2023年度は、感染が落ち着くと予想され、大腿四頭筋の腱膜の形態的・力学的特性の実験を滞りなく実施できると考えられます。未使用額はその経費に充てる予定です。
