Healthcare is characterized by professional, organizational, and institutional boundaries. Digital health innovations can help overcome these boundaries by providing information access to all healthcare professionals. Such innovations emerge from inputs from different health professionals at different positions along the entire care process and have the potential to substantially change the way in which interprofessional tasks are performed among the involved professionals. Consequently, as less empowered professionals, physiotherapists may resist the adoption of digital health innovations in particular if the innovation is dominated by physicians, and thus the not-invented-here syndrome may become a major barrier. We aim to examine whether the origin of a digital health innovation affects German physiotherapists’ adoption decision and whether the collaboration quality and physiotherapists’ proactive job crafting behavior may help overcome adoption barriers. We applied a mixed-method sequential design with a qualitative study one in which we interviewed 20 physiotherapists to provide exploratory insights, and a quantitative study two in which we tested our proposed hypotheses with survey data including an experimental vignette from 165 physiotherapists. Physiotherapists adopt digital health innovations developed by their own professional group more likely than digital health innovations developed by physicians. Our results also confirm that physiotherapists’ job crafting behavior and the quality of the collaboration with physicians weaken the resistance against physician-driven innovations. Our study underlines (1) the need to involve allied health professionals as physiotherapists in digital health innovation development, (2) the relevance of interprofessional collaboration in daily practice and, (3) an open mind set of allied health professionals to cope with innovation adoption barriers.医疗保健领域以专业、组织与制度层面的边界为显著特征。数字健康创新（digital health innovations）可通过为全体医疗从业者提供信息获取渠道，打破此类边界。此类创新源自照护全流程中不同岗位的多元健康从业者的参与贡献，并有潜力从根本上重塑相关从业者间跨专业任务的执行模式。因此，作为话语权相对较弱的专业人员，物理治疗师（physiotherapists）可能会抵触数字健康创新的采纳，尤其当此类创新由医师主导时，此时非我所创综合征（not-invented-here syndrome）或将成为主要采纳障碍。本研究旨在探究数字健康创新的研发归属是否会影响德国物理治疗师的创新采纳决策，同时验证协作质量与物理治疗师的主动性工作重塑行为是否有助于破解采纳障碍。本研究采用混合方法序贯设计：首先开展质性研究（qualitative study），通过访谈20名物理治疗师获取探索性研究发现；随后开展量性研究（quantitative study），基于包含165名物理治疗师参与的情境实验调查数据，对本研究提出的研究假设进行检验。相较于医师主导研发的数字健康创新，物理治疗师更倾向于采纳本专业团队研发的同类创新。研究结果同时证实，物理治疗师的工作重塑行为及与医师的协作质量，可有效缓解其对医师主导型创新的抵触情绪。本研究强调三点核心内容：其一，需吸纳物理治疗师这类辅助医疗专业人员参与数字健康创新的研发工作；其二，跨专业协作在日常临床实践中的重要价值；其三，辅助医疗专业人员需以开放心态应对创新采纳障碍。
