The Effect of Functional Exercise Based on the Theory of Dynamic and Static Complementary Balance on Hip Joint Function Rehabilitation in Patients Undergoing Total Hip Arthroplasty
Abstract：Objective To explore the effect of functional exercise based on the theory of dynamic and static complementary balance on postoperative pain and hip joint function in patients undergoing total hip arthroplasty. Methods A prospective study was conducted on 84 patients who underwent total hip arthroplasty at the Department of Rehabilitation Medicine, Chengdu Bayi Orthopedic Hospital from June 2023 to June 2024. The patients were randomly divided into a control group and an observation group, with 42 cases in each group. The control group received conventional rehabilitation intervention, while the observation group received functional exercise intervention based on the theory of dynamic and static complementary balance. The postoperative pain and complications between the two groups were compared, as well as the hip joint function and lower limb function. Results The resting and activity visual analogue scale (VAS) scores of the observation group at 24, 36, and 48 hours after surgery were lower than those of the control group, with statistically significant differences (t=3.223, 2.749, 3.331, 3.312, 4.419, 3.053, P<0.05). The incidence of complications in the observation group was 2 cases (4.76%), which was lower than that of the control group (8 cases, 19.05%), with a statistically significant difference (x2=4.087, P<0.05). At 3 months post-surgery, the pain score, functional score, joint range of motion score, and limb deformity score in the observation group's Harris hip score were higher than those in the control group, with statistically significant differences (t=3.945, 4.299, 3.871, 3.723, P<0.05). The time taken for the timed up and go test (TUGT) in the observation group was shorter than that in the control group, with a statistically significant difference (t=8.277, P<0.05). Conclusion Implementing functional exercise based on the theory of dynamic and static complementary balance in patients undergoing total hip arthroplasty helps effectively relieve postoperative pain, reduce related complications, and further improve the rehabilitation effects of hip joint and lower limb functions.
