超音波画像装置と三次元動作解析装置の同期による筋骨格系組織の動態解析に挑戦
　超音波画像装置による評価の多くは、座位や立位など静的な姿勢で行われます。そこに、三次元動作解析装置を同期することで、歩行といった動的な条件下での筋骨格系組織の動態解析に成功しました。歩行中に骨や筋がどのような動きをしているか、可視化して分析を行います。BGU Murnauとの共同研究で、外反母趾やアキレス腱症など、整形外科的疾患の発症メカニズムの解明に迫ります。

ハムストリング肉ばなれ・鼠径部痛症候群に対する主観的アンケート評価の妥当性の実践的課題

　ハムストリング肉ばなれや鼠径部痛症候群は再発しやすいスポーツ傷害として知られています。

　危険因子は、既往歴や筋力低下をはじめとして数多く報告されていますが、我々はアスリートの主観的症状に着目しました。デジタル社会の強みを活かして、オンラインで評価を実施することで選手だけでなく評価者の負担も軽減でき、定期的な評価の継続を加速させることができます。評価スコアの発案者であるDr. Andersと共同で、日本語版の妥当性の検証を進めています。

足関節装具がジャンプ動作時の下肢関節キネマティクスに及ぼす影響の検証

　足関節捻挫は最も代表的なスポーツ外傷の一つであり、繰り返すことで慢性足関節不安定症の発症にもつながります。受傷予防に用いられる足関節装具の着用によって、ジャンプ動作における下肢関節のキネマティクスの変化を分析しています。さらにContinuous relative phase(CRP)に着目し、運動制御と協調性変動についての検証に取り組んでいます。PolyUのDr. Kobayashiとの共同研究で、理学療法学と医用工学を組み合わせた研究の発展を進めています。
