Introduction and objectiveThe Bachelor Thesis (BT) is a compulsory subject in the Physiotherapy Degree. The objective of this work was to elaborate an exploratory analysis of the BT in the Spanish Universities 12years after its implementation. Material and methodsCross-sectional descriptive study using a structured search on the websites public and private Spanish universities offering Physiotherapy Degrees. The variables studied were number of credits, timing, type of work, teaching guide, language, distribution of hours, supervisor profile, evaluation system and defense format. Results57 degrees in 53 universities were analysed. The number of credits most frequently assigned was 6. Observed distribution of hours was face-to-face hours (17.5±19.5); hours of supervised work (18.8±21.3); hours of autonomous work (144.4±46.9). The most frequently used methodological design was the bibliographic review (n=24). In the evaluation criteria, the supervisor's rating ranged between 0 and 90% of the final mark (41.7±23.7) compared to 10-100% corresponding to the thesis evaluation panel (58.1±24.4). Only 21 degrees report the profile of the tutor teachers. ConclusionsThe assignment of credits, methodologies and evaluation systems are very heterogeneous among Spanish universities in the BT of the Physiotherapy Degree. After 15years since its implantation into the degree, it is necessary to establish a consensus to rationalize the subject.
