〔目的〕骨盤・下肢アライメントの年代間の相違とその性差を検討した．〔対象〕脊柱，下肢に整形外科的既往のない男女141名を，若年群，中年群，高齢群に分けた．〔方法〕骨盤前傾角度，膝伸展角度，骨盤傾斜角度，FTA，Q-angle，大腿骨前捻角，navicular drop test，leg-heel alignmentの測定を行った．〔結果〕高齢群でアライメント変化が著明に現れ，男性は膝屈曲方向，女性は骨盤後傾，股外旋，膝内反・屈曲方向へと変化することが示唆された．また，骨盤前傾角度，FTAは高齢群で性差がなくなることが明らかとなった．〔結語〕男女それぞれのアライメント変化の傾向を考慮し，理学療法を提供していくことが重要であると考える．, [Purpose] The purpose of this study was to examine the alignment of the pelvis and lower extremities in males and females of different age groups. [Subjects] The subjects were 141 healthy persons who were classified into three groups based on age: young, middle-aged, and elderly. [Methods] Anterior pelvic tilt, knee extension angle, lateral pelvic tilt, femoro-tibial angle (FTA), quadriceps angle, femoral anteversion, navicular drop test, and leg-heel alignment were measured. [Results] In the elderly group, significant changes of alignment due to aging were observed. Flexion of the knees was observed in both males and females. Posterior pelvic tilt, external rotation of the hip, and varus of the knees were observed in females. Anterior pelvic tilt and FTA did not show any difference between genders in the elderly group. [Conclusion] It is important to consider the tendency for alignment to change due to aging in each gender when providing physical therapy., 首都大学東京, 2015-03-25, 博士（理学療法学）, 甲第475号

本研究では，骨盤と下肢の姿勢分類と，それに関与するアライメント・関節可動域・筋力との関連について分析した。対象は若年健常者34名（男性15名，女性19名），平均年齢21.9歳であった。アライメント測定は骨盤・下肢の8項目に対して行い，関節可動域・筋力測定（最大等尺性収縮）は股・膝・足関節に対して行った。結果，姿勢はアライメント測定項目のうち大腿骨前捻角・大腿四頭筋角度・矢状面での膝関節角度を特徴として3群（内反膝群・膝過伸展群・外反膝群）に分類された。4群の男女比は内反膝群では男性，膝過伸展群，外反膝群で女性が有意に多かった。内反膝群では股内転・内旋可動域が有意に小さく，股外転筋力が有意に大きくなり，外反膝群ではその逆であった。膝過伸展群では膝伸展・足底屈可動域が有意に大きかった。若年健常者の姿勢は男性1群，女性2群の計3群に分類され，それぞれが特有のアライメント・関節可動域・筋力を有することが示唆された。, The purpose of this study was to analyze correlation of the posture classification of the pelvis and lower extremities with the alignment, range of motion (ROM) and muscle strength. Thirty four young healthy subjects (15 males and 19 females; mean age, 21.9 years) were participated. The measurement of the alignment included 8 items of the pelvis and the lower extremities, and the measurement of ROM and muscle strength (maximal isometric contraction) included the hip joint, knee joint, and the ankle joint. The types of posture were, in total, classified into three different groups: one male group characterized by genu varus, and two female groups characterized by genu recurvatum and genu valgus according to femoral anteversion, quadriceps angle, and knee joint angle (on a sagittal plane). ROM for adduction and internal rotation of the hip joint was significantly decreased and muscle strength for abduction of the hip joint was significantly increased in genu varus. In genu valgus the relation was the reverse of genu varus. ROM for extension of the knee joint and plantar flexion of the ankle joint was significantly increased in genu recurvatum. These results suggest that young healthy subject's posture was classified into one male group and two female groups; moreover, the results also suggest that each of them had characteristic alignment, ROM, and muscle strength., 首都大学東京学位論文甲第475号 副論文
