| Outline of Final Research Achievements |
The present study investigated the effect of functional leg length discrepancy on the extensibility of tensor fasciae latae and the effectiveness of the use of a shoe lift to correct the compensatory posture with functional leg length discrepancy for the tensor fascia latae extensibility using ultrasound shear wave elastography. In the condition of functional leg length discrepancy, the shear elastic modulus of the tensor fasciae latae decreased. In the condition of shoe lift, the shear elastic modulus of the tensor fasciae latae was restored. These results suggest that using the shoe lift for functional leg length discrepancy can result in a functional hip position, extending the tensor fasciae latae.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の知見より，人工股関節置換術後に生じた機能的脚長差に大腿筋膜張筋の伸張性低下が影響を及ぼす可能性があることを，超音波診断装置を用い証明することができた．さらに，機能的脚脚長差に対して，補高装具を用い股関節を伸展位に保つことは，大腿筋膜張筋の筋長を伸長させる効果があることが示唆された．したがって，機能的脚長差に対するリハビリテーション治療の選択肢のひとつとして補高装具が有効である可能性が見出された．
