This study aimed to evaluate the effect of stepping exercises in addition to conventional physical therapy on the recovery of muscle strength and walking speed after total hip arthroplasty.
This was a retrospective study with 6 wks of follow-up care and evaluation. Patients (n = 30) undergoing primary total hip arthroplasty for hip osteoarthritis were divided into two groups based on whether stepping exercises were performed after surgery. The control group (n = 15) received supervised conventional physical therapy for 6 wks. The stepping group (n = 15) performed stepping exercises with conventional physical therapy. Outcome measures were lower limb muscle strength and walking speed at 6 wks postoperatively.
The stepping group showed significantly higher recovery of the hip abductor and the knee extensor muscle strengths on the involved side compared with the control group. There were no significant differences between the two groups in walking speed and hip extensor, hip flexor and knee flexor strength on the involved side.
Our findings suggest that stepping exercises may be effective in facilitating the muscular recovery of the hip abductors and knee extensors in the early postoperative phase after total hip arthroplasty.
本研究旨在评估在常规物理治疗之外进行踏步练习对全髋关节置换术后肌肉力量和行走速度恢复的影响。
这是一项具有 6 周随访和评估的回顾性研究。将因髋关节骨关节炎接受初次全髋关节置换术的患者（n=30）根据术后是否进行踏步练习分为两组。对照组（n=15）接受 6 周的监督常规物理治疗。踏步组（n=15）在常规物理治疗中进行踏步练习。术后 6 周时评估下肢肌肉力量和行走速度。
与对照组相比，踏步组患侧髋关节外展肌和膝关节伸肌的力量恢复明显更高。两组之间在患侧的行走速度以及髋关节伸肌、髋关节屈肌和膝关节屈肌力量方面无显著差异。
我们的研究结果表明，在全髋关节置换术后的早期阶段，踏步练习可能有助于促进髋关节外展肌和膝关节伸肌的肌肉恢复。
