Randomization Procedure (please state who generates the random number sequence and by what method): |
A stratified block randomization method was used, with gender as the stratification factor. The randomization allocation codes were generated by a biostatistician using SAS 9.4 software on a computer. Allocation concealment was achieved using opaque sealed envelopes. Eligible participants were assigned a randomization number in sequence. An independent researcher opened the envelopes in order, recorded the person who opened the envelope and the time of opening, and assigned the participants to the two groups according to the randomization result. |

盲法: |
本研究采用严谨的盲法设计以控制偏倚: 1. 研究参与者盲:所有入组患者对自身分组情况不知情。他们被告知将接受一项涉及新型传感器评估的手术,但均不清楚评估结果是否被用于术中调整。两组采用完全相同的手术切口、术后包扎、镇痛及康复方案,确保了患者盲法的有效性。 2. 术者初始盲法与Sham程序:为控制术者操作可能带来的偏倚,我们引入了创新的“盲法外科医生”流程。在手术开始前及关键操作步骤中,外科医生对患者的分组信息不知情。 术中,由一名不参与手术和评估的独立研究协调员控制压力传感器显示界面。对于对照组患者,协调员屏蔽真实数据并向术者提供标准化虚假反馈;对于试验组患者,则显示真实数据。该Sham程序确保了两组手术体验的唯一区别在于“术者是否获得了真实反馈”,而非其他非特异性因素。 3. 结局评估者盲:所有负责术后随访、数据收集(包括量表评分、体格检查、影像学评估)的研究人员对患者的分组信息完全不知情。他们不参与手术过程,且被要求不得询问或猜测患者的分组。此举确保了主要和次要结局评估的客观性,有效控制了评估偏倚。 4. 数据分析者盲:在最终数据库锁定后,生物统计师将使用编码后的分组数据进行统计分析,直至生成统计报告初稿后方才揭晓代码对应关系,确保了分析过程的客观性。 |

Blinding: |
This study employs a rigorous blinding design to control bias: Participant Blinding: All enrolled patients are unaware of their group assignment. They are informed that they will undergo a surgery involving a novel sensor-based assessment but are not told whether the assessment results will be used for intraoperative adjustment. Both groups receive identical surgical incisions, postoperative dressings, analgesic protocols, and rehabilitation regimens, ensuring the validity of participant blinding. Surgeon Initial Blinding and Sham Procedure: To control for potential bias introduced by the surgeon’s actions, an innovative "blinded surgeon" process was implemented. Prior to the start of surgery and during key operative steps, the surgeon is unaware of the patient’s group assignment. During the procedure, an independent study coordinator who is not involved in the surgery or assessment controls the display interface of the pressure sensor. For patients in the control group, the coordinator shields the real data and provides standardized sham feedback to the surgeon; for patients in the experimental group, the real data are displayed. This sham procedure ensures that the only difference in the surgical experience between the two groups is whether the surgeon received real feedback, eliminating non-specific factors. Outcome Assessor Blinding: All researchers responsible for postoperative follow-up and data collection (including scale scores, physical examinations, and imaging assessments) are completely unaware of the patient’s group assignment. They are not involved in the surgical procedure and are instructed not to inquire or speculate about the patient’s group allocation. This ensures the objectivity of primary and secondary outcome assessments and effectively controls assessment bias. Data Analyst Blinding: After the final database is locked, the biostatistician conducts statistical analysis using coded group data. The code is not revealed until the initial draft of the statistical report is generated, ensuring the objectivity of the analytical process. |

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: |
本研究的数据采集和管理包括病例报告表(Case Report Form, CRF)和电子数据采集系统(Electronic Data Capture, EDC)两部分。 CRF用于记录受试者在研究过程中的各项研究数据,包括一般资料、既往病史、体格检查结果、实验室检查结果、影像学资料、术中观察与测量数据、围手术期资料以及术后各随访时间点的评价指标等。所有研究数据均应由经培训合格的研究人员按照研究方案要求及时、真实、准确、完整地填写。任何数据修改均须保留原始记录,并注明修改原因、修改日期及修改人,以保证研究数据的真实性和可追溯性。 EDC系统用于研究数据的电子化录入、存储、核查、管理和导出。本研究拟采用符合临床研究数据管理要求的电子数据采集平台进行数据管理,如ResMan系统。研究人员应根据CRF内容及时将相关数据录入EDC系统。EDC系统应具备权限分级管理、逻辑核查、数据追踪、修改留痕、数据备份及安全存储等功能,以保障研究数据的完整性、准确性和安全性。 为保证研究数据质量,本研究将建立统一的数据管理和质量控制流程。研究开始前,对所有参与研究的人员进行统一培训,明确数据填写、录入、核查及管理要求。研究实施过程中,将定期对CRF与EDC数据进行核对,对缺失值、异常值及逻辑错误进行质疑和核查,必要时由研究者予以更正和确认。数据库锁定前,应完成数据清理、质疑解决和质量审核;数据库锁定后,未经规定程序不得擅自修改数据。 本研究将严格保护受试者隐私和个人信息安全。所有受试者资料均采用唯一编码进行标识,研究数据库中不直接录入受试者姓名、身份证号、联系方式等可直接识别个人身份的信息。受试者身份信息与研究数据将分别保存,并由专人管理。除研究者、申办方授权人员、伦理委员会及监管部门因研究质量控制、审查或监管需要外,其他任何无关人员不得查阅研究资料。 所有研究资料,包括纸质CRF、知情同意书、原始记录及电子数据库等,将按照国家相关法律法规、伦理规范及本单位档案管理要求妥善保存,在研究结束后保存至规定年限,以备核查、审计和统计分析使用。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data collection and management in this study encompassed two components: the Case Report Form (CRF) and the Electronic Data Capture (EDC) system. The Clinical Record Form (CRF) is used to record various research data of the subjects during the study process, including general information, past medical history, physical examination results, laboratory test results, imaging data, intraoperative observation and measurement data, perioperative data, and evaluation indicators at various postoperative follow-up time points. All research data should be filled in by trained and qualified researchers in a timely, truthful, accurate, and complete manner according to the requirements of the research protocol. Any data modification must retain the original record, and indicate the reason for modification, modification date, and modifier, to ensure the authenticity and traceability of the research data. The EDC system is used for the electronic entry, storage, verification, management, and export of research data. This study intends to use an electronic data collection platform that meets the requirements of clinical research data management, such as the ResMan system. Researchers should promptly enter relevant data into the EDC system based on the content of the CRF. The EDC system should have functions such as permission level management, logical verification, data tracking, modification tracking, data backup, and secure storage to ensure the integrity, accuracy, and security of research data. To ensure the quality of research data, this study will establish a unified data management and quality control process. Before the study begins, all participants will undergo unified training to clarify the requirements for data filling, entry, verification, and management. During the implementation of the study, regular checks will be conducted on the Clinical Record Forms (CRF) and Electronic Data Capture (EDC) data, and missing values, outliers, and logical errors will be questioned and verified. If necessary, corrections and confirmations will be made by the researchers. Before the database is locked, data cleaning, resolution of questions, and quality review should be completed; after the database is locked, data should not be modified without following the prescribed procedures. This study will strictly protect the privacy and personal information security of the subjects. All subject data are identified using unique codes, and information that can directly identify individuals, such as the subjects' names, ID numbers, and contact information, will not be directly entered into the research database. The subjects' identity information and research data will be stored separately and managed by designated personnel. Except for researchers, authorized personnel of the sponsor, ethics committee, and regulatory authorities due to research quality control, review, or regulatory needs, no other unrelated personnel are allowed to access the research materials. All research materials, including paper CRFs, informed consent forms, original records, and electronic databases, will be properly stored in accordance with relevant national laws and regulations, ethical norms, and the archival management requirements of our institution. After the study is completed, they will be retained for the prescribed period for verification, audit, and statistical analysis. |
