Background: Functional hallux limitus (FHL) refers to dorsiflexion hallux mobility limitation when the first metatarsal head is under loading conditions but not in the unloaded state. The goal of the study was to evaluate 3 common manual tests (Buell, Dananberg, and Jack tests) for assessing first metatarsophalangeal joint (MPJ) mobility and determining the normal values needed to detect FHL, and clarify the signs and symptoms associated with this pathology. Methods: Forty-four subjects were included in this reliability study. Subjects were divided into healthy control (non-FHL) and FHL groups according to the Buell first MPJ limitation values in addition to signs and symptoms derived from the literature. In both groups, we measured the mobility in the Buell, Dananberg, and Jack tests using a goniometer; their intraclass correlation coefficients (ICCs), sensitivities, and specificity indexes were also calculated. Results: All techniques showed high reliability across measurement trials with ICCs ranging from 0.928 to 0.999. The optimal mobility grades for predicting FHL were 68.6 ± 3.7 degrees, 21 ± 5.9 degrees, and 25.5 ± 6.5 degrees (mean±SD) ( P < .05) for the Buell, Dananberg, and Jack tests, respectively. Conclusion: Normal and limited mobility values were established for assessing FHL using each technique. The sensitivity and specificity data were perfect for the Dananberg and Jack tests, thus identifying these tests as specific and valid tools for use in FHL diagnosis. Pinch callus was the sign most associated with FHL. Level of Evidence: Level II, comparative series.

Background: The COVID-19 pandemic has made it necessary to adapt university health-education. Virtual simulation has been proposed to be a suitable tool. Methods: A quasi-experimental study was conducted on nursing students in the final year. The virtual simulation platform vSim® was used. Improvements in knowledge, skills during simulation, satisfaction and self-confidence obtained through the training provided were analyzed, as well as satisfaction with the platform. Results: Pre-post training knowledge improved. Skill acquisition improved between the first and last attempts in all cases. The levels of self-confidence and satisfaction with the training and the platform used were high. Conclusions: The vSim® was a useful solution during the pandemic. Knowledge improved and high self-confidence was obtained.
