腸骨筋と大殿筋の筋緊張低下により立ち上がり動作・立位保持において後方への転倒の危険性を認めた両変形性膝関節症の症例

抄録

We administered physical therapy for a patient with knee osteoarthritis who had an increased risk of falling backward while standing up or standing. The patient experienced poor hip flexion during sitting and the flexion phase of standing up, causing the pelvis to tilt backward. Moreover, the extension of both hip joints was poor in standing and the flexion phase of standing up, which compromised the support of the upper limbs. Improved muscle tone in the iliacus muscle and gluteus maximus increased the flexion of both hip joints during sitting and the flexion phase of standing up. Additionally, the extension of both hip joints increased in standing. Consequently, the risk of falling backward was reduced in standing up and standing, which improved the patient's safety and standing ability.
