To describe the change with time of the reported methodological quality of randomized controlled trials of physiotherapy interventions.
For all trials of physiotherapy interventions indexed on the Physiotherapy Evidence Database (PEDro), year of publication, and methodological quality scores (11-item PEDro scale and total PEDro score [range, 0-10]) were extracted. The relationship between trial quality and time was evaluated using regression analyses for the PEDro total score and individual quality items. The study was carried out in a university research center.
Data from 10,025 trials published since 1960 were analyzed. The total PEDro score was related to time (year of publication), with the total score increasing by an average of ∼0.6 points each decade between 1960 and 2009. The reported use of eight of the 11 individual items from the PEDro scale (intention-to-treat analysis, concealed allocation, groups similar at baseline, reporting of results of between-group statistical comparisons, point measures and measures of variability reported, subjects randomly allocated to groups, eligibility criteria specified, and blinding of assessors) also improved with time.
The reported methodological quality of randomized controlled trials of physiotherapy interventions has improved over time. Further improvement is still necessary.
描述物理治疗干预措施随机对照试验报告的方法学质量随时间的变化。
对 Physiotherapy Evidence Database（PEDro）索引中的所有物理治疗干预措施试验，提取发表年份和方法学质量评分（11 项 PEDro 量表和总 PEDro 评分[范围，0-10]）。使用回归分析评估试验质量与时间的关系，分析总 PEDro 评分和个别质量项目。研究在大学研究中心进行。
分析了自 1960 年以来发表的 10025 项试验数据。总 PEDro 评分与时间（发表年份）相关，1960 年至 2009 年，总评分每十年平均增加约 0.6 分。PEDro 量表的 11 个单项中有 8 项（意向治疗分析、隐藏分配、基线组相似、组间统计比较结果报告、点测量和变异性测量报告、受试者随机分组、规定纳入标准和评估者盲法）的报告使用情况也随时间改善。
物理治疗干预措施的随机对照试验报告的方法学质量随时间推移有所提高。仍需进一步改进。
