研究目的:

本研究主要目的是比较五种不同负重条件下,脑卒中偏瘫患者患侧下肢髋、膝、踝关节在支撑相的峰值力矩不对称性的差异。次要目的是比较五种不同负重条件下,患者步态时空参数(步长、支撑相时间等)和运动学参数(关节活动范围)不对称性的差异。  

Objectives of Study:

The primary objective of this study was to compare the differences in peak moment asymmetry of the hip, knee, and ankle joints on the paretic side during the stance phase among five different loading conditions in stroke patients with hemiplegia. The secondary objective was to compare the differences in asymmetry of spatiotemporal gait parameters (e.g., step length, stance time) and kinematic parameters (e.g., joint range of motion) across the five loading conditions.

随机方法(请说明由何人用什么方法产生随机序列):

随机化: 本研究采用平衡拉丁方设计控制顺序效应。通过R软件(v 4.4.1)生成一个5×5的平衡拉丁方矩阵(基于Williams设计算法),确保每种条件在序列的每个位置出现且仅出现一次,且所有条件间的双向顺序平衡。 分组实现: 生成5种不同的测试序列顺序。将30例受试者通过完全随机抽样(使用R软件,设置固定随机种子seed=123)分配至这5种序列顺序之一,每组序列分配6例受试者。随机分配序列由不参与受试者招募和评估的研究人员生成并密封保存。 分配隐蔽: 测试序列顺序封装在不透光的密封信封中,信封外仅标注受试者编号。在受试者完成基线评估后,由研究协调员按顺序打开信封,告知测试人员本次研究的负重条件顺序。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization: This study utilized a balanced Latin square design to control for order effects. A 5×5 balanced Latin square matrix was generated using R software (v 4.4.1) based on the Williams design algorithm, ensuring that each condition appeared exactly once in every position of the sequence and that all possible pairwise orderings of conditions were balanced. Allocation Implementation: Five distinct testing sequences were generated. Thirty participants were randomly assigned to one of the five sequences using complete random sampling in R software, with a fixed random seed (seed=123), resulting in six participants per sequence. The allocation sequence was generated and kept in sealed envelopes by a researcher not involved in participant recruitment or assessment. Allocation Concealment: The testing sequences were placed in opaque, sealed envelopes labeled only with the participant identification number. After baseline assessments were completed, a study coordinator opened the envelopes in sequential order and informed the testers of the loading condition sequence for each participant.

盲法:

由于干预性质(负重)所限,对受试者和治疗师实施盲法较为困难。但本研究结局指标的测量(三维动作捕捉与测力台数据)为客观仪器测量,数据分析将由不知晓分组情况的独立研究人员完成,以此实施结局评估盲法。

Blinding:

Due to the nature of the intervention (loading), blinding of participants and therapists was not feasible. However, outcome measures in this study were collected using objective instrument-based methods (3D motion capture and force plate data). Data analysis was performed by an independent researcher who was unaware of group allocation, thereby implementing blinding for outcome assessment.

否No

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

本试验收集的个体参与者数据(IPD)不会公开共享,这主要是出于伦理和法律限制。首要原因是为了保护参与者的隐私,因为数据中包含敏感的个人信息。所有参与者签署的知情同意书明确说明,数据仅用于本研究项目的目的,并未包含对公共数据共享的同意。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Individual Participant Data (IPD) collected in this trial will not be publicly shared, primarily due to ethical and legal restrictions. The foremost reason is to protect participant privacy, as the data contain sensitive personal information. The informed consent forms signed by all participants explicitly stated that the data would be used solely for the purposes of this research project and did not include consent for public data sharing.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据收集和管理将使用一个双组分系统进行:包括用于研究现场初始数据记录的纸质病例报告表(CRF),以及用于数据输入、存储和管理的基于网络的电子数据采集(EDC)系统。在这项研究中,我们将利用ResMan EDC系统(www.medresman.org)来确保数据的完整性和安全性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection and management will be conducted using a dual-component system: paper-based Case Report Forms (CRFs) for initial on-site data recording at the study site, and a web-based Electronic Data Capture (EDC) system for data entry, storage, and management. In this study, the ResMan EDC system (www.medresman.org) will be utilized to ensure data integrity and security.
