随机方法(请说明由何人用什么方法产生随机序列):

本研究将采用区组随机化方法,使用计算机软件生成随机数字序列,以确保三组在整个招募过程中样本量均衡。由本单位不参与本临床试验的独立统计师,使用统计软件SAS 9.4 (Proc Plan) 生成随机分配序列。设定区组长度为6或9,按 1:1:1 的比例生成分为三组(A、B、C)的随机序列。序列清单将严格保密。

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

This study will employ a block randomization method. A computer-generated random number sequence will be used to ensure sample size balance across the three groups throughout the recruitment period. An independent statistician, not otherwise involved in the conduct of this clinical trial, will generate the random allocation sequence using the statistical software SAS 9.4 (Proc Plan). Block sizes of 6 or 9 will be set to generate a random sequence allocating participants to the three groups (A, B, C) in a 1:1:1 ratio. The allocation sequence list will be kept strictly confidential.

是否公开试验完成后的统计结果:

盲法:

鉴于三组干预措施(常规康复、语音阀训练、闭环控制训练)在物理形式和操作上存在本质差异,本研究无法对受试者和干预实施者(治疗师)实施盲法。为最大限度减少测量偏倚和分析偏倚,本研究将严格执行结局评估者和数据分析人员设盲。 结局评估者盲: 所有指标(FEES录像、MASA评分表等)将由不知晓受试者分组信息和评估时间点的两名独立评估员进行评阅。所有评估资料将在评估前进行脱敏和随机化编号处理。 数据分析盲: 在最终的统计分析阶段,数据分析师将使用一组临时代码(如A组、B组、C组)来代替真实的分组名称,直至完成主要结果的统计学检验后才会揭盲。

Blinding:

Given the essential differences in the physical form and application of the three interventions (conventional rehabilitation, speaking valve training, and closed-loop control training), it is not feasible to blind the subjects and intervention practitioners (therapists) to group assignment in this study. To minimize measurement bias and analysis bias to the greatest extent possible, this study will rigorously implement blinding of outcome assessors and data analysts. Outcome Assessor Blinding: All outcome measures (e.g., FEES videos, MASA score sheets) will be assessed by two independent evaluators who are blinded to subject group allocation and assessment time points. All evaluation materials will be anonymized and assigned random identification numbers prior to assessment. Data Analyst Blinding: During the final statistical analysis stage, the data analyst will use a set of temporary codes (e.g., Group A, Group B, Group C) in place of the true group names. Blinding will be maintained until the completion of the statistical testing for the primary outcomes.

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:

数据采集: 本研究采用 病例报告表(Case Report Form, CRF) 收集受试者人口学资料、健康信息及舌压测量结果。所有测量由经过统一培训的研究人员完成,确保操作标准化、一致性。数据采集过程包括:受试者基本信息登记 → 实验前测量 → 结果记录在纸质 CRF 中。 电子采集和管理:纸质 CRF 数据将由专人录入电子采集和管理系统(Electronic Data Capture, EDC),如 ResMan 平台。EDC 系统具备数据验证、逻辑检查、权限管理和审计追踪功能,确保数据完整性和可追溯性。录入数据须经双人核对,发现错误及时更正并记录修订人及日期。 数据管理与安全:数据分为纸质源文件与电子数据库两部分,均采用编号管理和加密保存。 电子数据定期备份至安全服务器,确保数据不丢失。 所有数据在公开前进行匿名化处理,保护受试者隐私。

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

Data Collection and Management Data Collection: Data on participant demographics, health information, and tongue pressure measurements will be collected using Case Report Forms (CRFs). All assessments will be performed by research staff who have undergone centralized training to ensure standardized and consistent procedures. The data collection process includes: registration of basic participant information → pre-intervention measurements → recording of results on paper-based CRFs. Electronic Capture and Management: Data from the paper CRFs will be entered into an Electronic Data Capture (EDC) system (e.g., the ResMan platform) by dedicated personnel. The EDC system features data validation, logic checks, access control, and an audit trail to ensure data integrity and traceability. All entered data will be double-checked by a second individual. Any identified errors will be promptly corrected, with the reviser's identity and revision date recorded. Data Management and Security: Data will be managed in two formats: paper-based source documents and an electronic database. Both will be managed using participant identification numbers and stored securely with encryption. Electronic data will be backed up regularly to a secure server to prevent data loss. All data will be anonymized prior to any public release to protect participant privacy.
