全人工股関節置換術後の靴下着脱動作訓練プログラム

The exercise program for taking on and off shoe socks post-total hip arthroplasty

要旨：本研究は，全人工股関節置換術後の靴下着脱動作訓練プログラムを術前から立案するために，我々が過去に調査した結果をまとめたものである．我々の調査では，靴下着脱動作に必要な股関節の関節可動域(ROM)は，屈曲平均83.5°，外転平均27.7°，外旋平均33.3°であった．また，指極(両肩関節外転90°位での中指間距離)が身長より4cm以上長い患者では，平均値以下のROMにて動作が可能となることが多く，短いものほどROMが増大する傾向が認められ，とくに外旋角度の増大が認められた．以上の結果をもとに，術前の動作方法，股関節ROM，身長，指極から術後の靴下着脱動作が予測可能となり，訓練プログラムの立案が可能となった．

　In order to make a post-operation program for taking on and off shoe socks before total hip arthroplasty, we summarized the results that we investigated. In our past investigation, we found that mean hip joint angles for taking on and off shoe socks were 83.5 degrees for flexion, 27.7 degrees for abduction, and 33.3 degrees for external rotation. A patient whose arm span is 4cm longer than his or her height could take on and off shoe shocks using lower angles than the mean hip joint angles we described above. Furthermore, the shorter a patient's arm span was, the bigger hip angles were asked for taking on and off shoe shocks, especially the angle of hip external rotation. We found that information on how a patient used to take on and off shoe sock before operation, hip joint angles, height, and length of his or her arm span make it possible to make a post-operation program.
