The scientific literature has a multitude of strengthening exercises recommended, and they have been criticized for not adhering to best practice and for being poorly reported. The aims of this scoping review were to (i) describe what foot and ankle strengthening exercises have been recommended in the scientific literature, (ii) compare the prescription of these exercises to best practice recommendations, and (iii) assess the completeness of the reporting of these exercises and exercise programs.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This scoping review was conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews. A systematic search of peer-review journal articles was conducted on 23 February 2023. Study designs that were included were experimental, quasi-experimental, feasibility, pilot studies, and observational. For each study included in the review, study design and participant details such as age, sex, and conditions treated were noted. To describe the foot and ankle strengthening exercises, each exercise was noted, which included its name, the number of sets and repetitions recommended, the load type and its magnitude, and whether there were any progression strategies. Exercises were grouped according to primary movement and a general exercise descriptor. To compare to best practice, each program's prescription parameters of frequency, intensity, and time were compared to the American College of Sports Medicine's (ACSM) guidelines. To assess completeness of reporting, each study was assessed with the Consensus on Exercise Reporting Template (CERT).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The search yielded 1511 documents, and 87 were included after full-text screening.

Teaching the FPI-6 can be challenging but 3D foot models provide a controlled risk-free way to practice, potentially reducing anxiety and increasing confidence. This study examined the effects of 3D foot models on podiatry students' confidence and anxiety when performing the FPI-6 and compared their scores to experts.</p><p><strong>Methods: </strong>Fifty podiatry students from three Australian universities used the FPI-6 to score nine 3D printed foot models ranging from -11 (highly supinated) to +12 (highly pronated). Students' self-confidence and anxiety were measured before and after exposure to the 3D foot models using a 10-item self-confidence questionnaire and the 27-item Competitive State Anxiety Inventory-2 (CSAI-2). Changes in self-confidence were analysed with paired t-tests, whereas median differences in CSAI-2 scores pre- and post-intervention were assessed using the Wilcoxon signed-rank test.
