A lower extremity rehabilitation system for ground training at 16 weeks after total hip arthroplasty: a randomized controlled trial

Abstract

Abstract Objective To observe the effect of the lower limb rehabilitation system on the function of the lower limbs of patients after total hip replacement, and to explore the advantages and clinical application value of the lower limb rehabilitation system. Methods Sixty patients admitted to the orthopaedic ward of the Affiliated Hospital of Chengdu University from January 2021 to June 2021 who underwent total hip arthroplasty for different etiologies were analyzed.The patients were divided into a conventional rehabilitation group (Group A) and a lower limb rehabilitation system rehabilitation group (Group B) using a random number table, with 30 cases in each group.Fugl-Meyer scores were collected at the follow-up visits after 8, 12 and 16 weeks of rehabilitation treatment respectively. Holden Functional Ambulation Classification (FAC) data were collected at the follow-up visits after 16 weeks of rehabilitation treatment for evaluation and analysis. Peak moment values, single foot support time, step frequency and 10m maximum walking speed were collected at week 16 using the lower limb rehabilitation system. Results There was no statistical difference between the general data of the two groups and they were comparable. After 16 weeks of training, the Fugl-Meyer scores of limb function increased in both groups as the training time increased; the Fugl-Meyer scores of limb function were higher in Group B than in Group A for the same training time (P < 0.05); there was a statistical difference in the comparison of unipedal support time, peak hip torque, stride frequency and maximum walking speed between the two groups (P < 0.05). Lower limb function was better in Group B than in Group A. However, there was no statistical difference between the two groups in Holden's Functional Ambulation Classification (FAC) (p > 0.05). Conclusion The Lower Limb Rehabilitation System combined with conventional rehabilitation training can significantly improve the lower limb motor function, balance function and walking ability of patients after total hip arthroplasty in the early postoperative period, enabling patients to recover better and faster, and has greater clinical application value.
