[Purpose] Information about clinical trials related to physical therapy (CTPT) in Japan, which has the highest aging rate in the world, is essential for physical therapy education, research, and policymaking to change and strengthen the education system and promote research grants. This survey aimed to clarify the proportion of CTPT in the clinical registry and compare the proportion of CTPT in Japan with that in North America. [Participants and Methods] The ClinicalTrials.gov (CTG) and National Institute of Public Health (NIPH) Clinical Trials were used. The number and proportion of CTPT were compared each year. The analyzed data spanned 10 years from 2010 to 2019. [Results] A total of 222,821 trials were registered in CTG during the 10 years. In search of "physical therapy", 3,001 trials searched. The proportion of CTPT increased from 0.8% to 1.7%. In total 42,194 trials were registered in the NIPH Clinical Trials Search. From the CTPT, 141 trials were obtained. The proportion of CTPT increased from 0.05% to 0.5%. The proportion of CTPT in the NIPH Clinical Trials Search was one-third or less than that in the CTG. The proportion of CTPT in CTG increased yearly, but the proportion of CTPT in NIPH Clinical Trials Search has not increased since 2016. [Conclusion] The proportion of CTPT is relatively low in Japan, compared with that in North America, and it showed no increasing trend. It is important to provide education and support for clinical trials in an aging country such as Japan.
[目的] 在全球老龄化率最高的日本，有关物理治疗相关临床试验（CTPT）的信息对于物理治疗教育、研究以及政策制定至关重要，有助于改变和加强教育体系并促进研究资助。本调查旨在明确CTPT在临床注册中的比例，并将日本的CTPT比例与北美地区进行比较。[参与者与方法] 使用了ClinicalTrials.gov（CTG）和日本国立公共卫生研究所（NIPH）的临床试验数据。每年对CTPT的数量和比例进行比较。分析的数据涵盖了2010年至2019年的10年时间。[结果] 在这10年期间，CTG共登记了222,821项试验。搜索“物理治疗”，共检索到3001项试验。CTPT的比例从0.8%增至1.7%。NIPH临床试验搜索中总共登记了42,194项试验。从CTPT中获得了141项试验。CTPT的比例从0.05%增至0.5%。NIPH临床试验搜索中CTPT的比例是CTG中的三分之一或更低。CTG中CTPT的比例逐年增加，但自2016年以来，NIPH临床试验搜索中CTPT的比例未再增加。[结论] 与北美相比，日本CTPT的比例相对较低，且无上升趋势。在日本这样的老龄化国家，为临床试验提供教育和支持很重要。
