Abstract	〔要旨〕本研究は片脚立ち上がりテスト(SLST)の成績と片脚着地時の股関節, 膝関節屈曲角度, 膝関節筋力の関係について検討することを目的とした. 整形外科的徴候のない65名に20cm台からSLSTを行わせ, 可能群と不可群の2群に分類した. 片脚着地動作の解析では, 腸骨稜最上部(a), 大転子(b), 大腿骨外側上顆(c), 外果(d)にマーカーを貼付し, 30cm台から着地動作を行わせ, 側方からハイスピードデジタルカメラで撮影した. (a)(b)(c)でなす角と(b)(c)(d)でなす角から, 股関節, 膝関節の屈曲角度を算出し, つま先接地から最大下腿前傾時の股関節, 膝関節の屈曲角度偏位量を解析パラメータとした. さらに, 徒手筋力計を用いて膝90°屈曲位における等尺性膝伸展, 屈曲筋力を計測し, 計測項目の群間比較を行った. その結果, 可能群は不可群に比べ着地時の股・膝関節屈曲角度が有意に大きかった. また, 2群間で膝伸展筋力に差はなかったが, 膝屈曲筋力は可能群が有意に高かった. 20cm台からSLSTが可能な者は, 着地時の股関節, 膝関節屈曲角度が大きく, 膝屈曲筋力も高いことが示唆された.

Abstract	[Abstract] The purpose of this study was to investigate the relationships between the single-leg standing-up test (SLST), hip/knee flexion angles during single-leg landing and knee muscle strength. Sixty-five subjects without any orthopaedic symptoms were included in the study. The subjects were classified into higher and lower SLST ability groups depending on whether they could perform SLST from the 20cm level. For the kinematic analysis of landing, single-leg landing motion from a 30cm high platform was videotaped from the lateral side. Markers were attached to bony landmarks in the pelvis and lower limbs, and knee and hip flexion angles were measured on the video image. Isometric knee extensor and flexor strength were also evaluated. During the data analysis, the obtained results were compared between the groups. The comparative analyses showed that the hip and knee flexion angles on landing were significantly larger and the knee flexor strength was significantly greater in the group exhibiting higher SLST ability. These results suggest that larger hip and knee joint flexion angles on single-leg landing and higher knee flexor strength are associated with superior performance in the SLST.
