Results Before treatment, there was no significant difference in Harris score, joint stiffness score, Berg balance scale and fall index between the two groups(all P>0.05). After treatment, the Harris score and Berg balance scale were increased in the two groups(t=31.131, 3.580, 50.783, 2.384, all P<0.05), the joint stiffness score and fall index were decreased in the two groups(t=13.740, 7.990, 26.259, 19.156, all P<0.05). Compared with the control group, the Harris score and Berg balance scale of the observation group were significantly increased, and the joint stiffness score and fall index were significantly decreased(t=15.663, 2.176, 13.588, 11.890, all P<0.05). Before treatment, there was no significant difference in isokinetic muscle strength with the affected hip, healthy hip, affected knee and healthy knee in the two groups(all P>0.05). After treatment, the isokinetic muscle strength with the affected hip, healthy hip, affected knee and healthy knee were increased in the two groups(t=4.384, 3.051, 2.589, 3.867, 3.021, 4.370, 2.240, 3.223, 4.591, 3.643, 3.452, 6.060, 6.008, 4.542, 5.738, 5.181, 6.116, 3.456, 5.164, 6.524, 6.402, 5.879, all P<0.05). Compared with the control group, the isokinetic muscle strength with the affected hip, healthy hip, affected knee and healthy knee of the observation group were increased significantly(t=2.209, 2.493, 2.278, 2.493, 2.458, 2.577, 2.603, 2.493, 2.105, 2.369, 2.278, 2.119, all P<0.05). Compared with the control group, the total effective rate of treatment in the observation group was significantly increased (P<0.05).
