The aim of this study is to investigate the effects of a preoperative combined with postoperative moderate-intensity progressive resistance training (PRT) of the operative side in patients with hip osteoarthritis (HOA) who are undergoing total hip arthroplasty (THA). The study seeks to evaluate the impact of this combined intervention on muscle strength, gait, balance, and hip joint function in a controlled, measurable, and objective manner. Additionally, the study aims to compare the outcomes of this combined intervention with those of preoperative or postoperative muscle strength training conducted in isolation.
A total of 90 patients with HOA scheduled for unilateral primary THA were randomly assigned to three groups: Pre group (preoperative PRT), Post group (postoperative PRT), and Pre& Post group (preoperative combined with postoperative PRT) focusing on hip flexion, extension, adduction, and abduction of operated side. Muscle strength, gait parameters, balance, and hip function were assessed at specific time points during a 12-month follow-up period.
All three groups showed significant improvements in muscle strength, with the Pre& Post group demonstrating the most pronounced and sustained gains. Gait velocity and cadence were significantly improved in the Pre& Post group at 1-month and 3-month postoperative follow-ups compared to the other groups. Similarly, the Pre& Post group exhibited superior balance performance at 3-month and 12-month postoperative follow-ups. The Harris Hip Score also showed better outcomes in the Pre& Post group at all follow-up intervals.
Preoperative combined with postoperative moderate-intensity PRT in HOA patients undergoing THA led to superior improvements in muscle strength, gait, balance, and hip joint function compared to preoperative or postoperative PRT alone. This intervention shows significant promise in optimizing postoperative rehabilitation and enhancing patient outcomes following THA.
本研究旨在探讨术前联合术后中等强度渐进性抗阻训练（PRT）对接受全髋关节置换术（THA）的髋骨关节炎（HOA）患者手术侧的影响。该研究旨在通过控制、可测量和客观的方式评估这种联合干预对肌肉力量、步态、平衡和髋关节功能的影响。此外，该研究旨在将这种联合干预的结果与术前或术后单独进行的肌肉力量训练的结果进行比较。
共 90 例接受单侧初次 THA 的 HOA 患者被随机分为三组：术前组（术前 PRT）、术后组（术后 PRT）和术前联合术后组（术前联合术后 PRT），重点关注手术侧的髋关节屈伸、内收和外展。在 12 个月的随访期间，在特定时间点评估肌肉力量、步态参数、平衡和髋关节功能。
所有三组肌肉力量均显著提高，术前联合术后组的提高最为显著和持久。与其他组相比，术前联合术后组在术后 1 个月和 3 个月的步态速度和步频显著提高。同样，术前联合术后组在术后 3 个月和 12 个月的平衡表现也更为出色。Harris 髋关节评分也显示术前联合术后组在所有随访间隔的结果更好。
术前联合术后中等强度 PRT 可显著改善 HOA 患者接受 THA 术后的肌肉力量、步态、平衡和髋关节功能，优于术前或术后单独进行 PRT。这种干预在优化术后康复和提高 THA 后患者的结果方面显示出了显著的前景。
