ABSTRACT
Objective:To explore the effect of core muscle strength training intervention on postoperative rehabilitation of patients after total knee arthroplasty, and to provide reference for the rehabilitation of patients after total knee arthroplasty.Methods:A total of 109 patients with total knee arthroplasty who were admitted to Medical Health Group of First People′s Hospital of Xiangshan County from May 2020 to July 2021 were selected as the research objects, and were divided into an intervention group of 54 cases and a control group of 55 cases according to the random number table method. The control group received conventional rehabilitation methods after surgery, and the intervention group received core muscle strength training on the basis of conventional rehabilitation. The intervention time was 6 weeks. The knee joint function, balance function and activities of daily living were evaluated by Hospital for Special Surgery Knee Score, Berg Balance Scale, modified Barthel Index before and after intervention and the results were compared between the two groups.Results:In the end, there were 50 cases in the intervention group and 52 cases in the control group. There was no significant difference in the score of the knee joint function, balance function and activities of daily living before intervention between the two groups( P>0.05). The scores of the knee joint function, balance function and activities of daily living were (74.78 ± 3.12), (46.50 ± 3.82), (92.80 ± 5.17) points in the intervention group, and (72.15 ± 3.31),(44.44 ±3.66),(89.42 ± 4.50) points in the control group, the differences were statistically significant ( t=4.12, 2.78, 3.52, all P<0.01). The knee joint function recovery grade in the intervention group was higher than that in the control group, and the difference was statistically significant ( Z=3.43, P<0.01); the degree of dependence on self-care ability in daily life in the intervention group was lower than that in the control group, and the difference was statistically significant ( Z=3.98, P<0.01). Conclusions:Core muscle strength training can effectively improve postoperative knee function, balance function and activities of daily living in patients with total knee arthroplasty. This program is practical in clinical work and has clinical application value.
