Abstract

Background: Total knee arthroplasty has proven to be an effective method for treating severe osteoarthritis, but this procedure may induce abnormal symptoms of gait and muscle synergy after surgery. Motor imagery is a special means of training that can heighten cortical-spinal excitability and spinal transmission efficiency. The training method can fortify muscle strength, enhance joint range of motion, and ameliorate gait and muscle synergy control patterns, all while avoiding postoperative intense pain resulting from high-intensity exercise. This study aims to investigate whether motor imagery training can improve patients' gait function and muscle synergy patterns, and to establish the effectiveness of motor imagery training in fostering postoperative knee joint function recovery in total knee arthroplasty patients.

Methods: This study will utilize a single-blind randomized clinical trial methodology. The research will aim to recruit forty patients from Guilin Medical College Affiliated Hospital who have undergone total knee arthroplasty and who meet the trial criteria. Random allocation to either the experimental group or the control group will be conducted for these patients. Participants in both the experimental and control groups will receive a 6-week conventional training intervention beginning on the first day after surgery and 5 sessions of rehabilitation training per week. In addition, the participants in the experimental group will receive motor imagery training alongside the conventional training programme. The parameters of gait, muscle synergy, lower limb kinematics and kinetics, isokinetic muscle strength, proprioception, and knee joint scoring will be measured one week before surgery and at 3, 6, and 12 weeks after surgery.

Discussion: This protocol is to evaluate the function of motor imagery training after total knee arthroplasty by analysing the parameters of gait and muscle synergy. The outcomes of this trial are expected to affirm the utility of motor imagery training in the postoperative rehabilitation of total knee arthroplasty patients.

全膝关节置换术后运动意象训练对步态和肌肉协同作用的影响:随机对照试验的研究方案。
背景:全膝关节置换术已被证明是治疗严重骨关节炎的有效方法,但手术后可能会引起步态和肌肉协同的异常症状。运动想象是一种特殊的训练手段,可以提高皮质-脊髓兴奋性和脊髓传递效率。该训练方法可以增强肌肉力量,增强关节活动范围,改善步态和肌肉协同控制模式,同时避免术后高强度运动引起的剧烈疼痛。本研究旨在探讨运动意象训练是否能改善患者的步态功能和肌肉协同模式,并建立运动意象训练促进全膝关节置换术患者术后膝关节功能恢复的有效性。方法:本研究采用单盲随机临床试验方法。该研究的目标是在桂林医学院附属医院招募40名接受过全膝关节置换术并符合试验标准的患者。将这些患者随机分配到实验组或对照组。实验组和对照组从术后第一天开始进行为期6周的常规训练干预,每周进行5次康复训练。此外,实验组的参与者将在常规训练计划的基础上接受运动意象训练。步态参数、肌肉协同、下肢运动学和动力学、等速肌力、本体感觉和膝关节评分将在手术前一周和手术后3、6和12周测量。讨论:本方案是通过分析步态和肌肉协同参数来评估全膝关节置换术后运动意象训练的功能。该试验的结果有望证实运动意象训练在全膝关节置换术患者术后康复中的作用。试验注册:中国临床试验注册中心ChiCTR2400082292。于2024年3月26日注册。

期刊介绍: Trials is an open access, peer-reviewed, online journal that will encompass all aspects of the performance and findings of randomized controlled trials. Trials will experiment with, and then refine, innovative approaches to improving communication about trials. We are keen to move beyond publishing traditional trial results articles (although these will be included). We believe this represents an exciting opportunity to advance the science and reporting of trials. Prior to 2006, Trials was published as Current Controlled Trials in Cardiovascular Medicine (CCTCVM). All published CCTCVM articles are available via the Trials website and citations to CCTCVM article URLs will continue to be supported.
