Abstract: Charcot neuropathic osteoarthropathy is commonly known as 'Charcot foot'. It is a serious foot complication of diabetes mellitus that can frequently lead to foot ulceration, gangrene, hospital admission and foot utation. A multidisciplinary approach to the management of Charcot foot is taken involving medical and allied health professionals. The management approach may also differ between different countries. To date, there is no systematic review of the literature undertaken to identify the clinical effectiveness of non-operative interventions in the treatment of acute Charcot foot. The objective of this review was to identify the effectiveness of non-surgical interventions with reducing lesions, ulceration, the rate of surgical intervention, reducing hospital admissions and improve the quality of life of subjects with Charcot foot. A comprehensive search strategy was undertaken on databases available from University of South Australia from their inception to November 2006. Randomised controlled trials or clinical controlled trials were primarily sought. Critical appraisal of study quality and data extraction was undertaken using Joanna Briggs Institute instruments. Review Manager software was used to calculate comparative statistics. This review identified 11 trials and five trials were included in the review. Three trials involved the use of bisphosphonate, a pharmacological agent. Two experimental treatments were also included, evaluating palliative radiology and magnetic fields. No trials were found using immobilisation and off-loading interventions for acute Charcot foot. The overall methodological quality score of the five studies was moderate. Owing to heterogeneous data, meta-analysis could not be performed.The trials did not report on reducing lesions, ulceration, rate of surgical intervention, hospital admissions and the quality of life of subjects with Charcot foot.The trials evaluating bisphosphonates reported greater reduction in foot temperature and disease activity for intervention subjects compared with controls. Another outcome of this review indicated additional beneficial effects of bisphosphonates in reducing pain and discomfort. The trial evaluating palliative radiotherapy found no difference between groups on any outcome. A significant reduction in the amount of deformity and reduced healing time to consolidation was found after treatment in the group receiving magnetic therapy treatment. There is a lack of clinical trials evaluating the effectiveness of non-operative interventions for the management of Charcot foot (immobilisation, removable cast walkers, advice/dispensing of footwear and prescribing of orthotics). Bisphosphonates may be useful adjuncts to standard management of Charcot foot by improved healing demonstrated by a reduction in disease activity indicated by skin temperature and bone destruction. Magnetic therapy may reduce deformity, joint destruction and improve mobility. There is a lack of evidence supporting the use of pharmacological or non-surgical interventions with reducing lesions, ulceration, rate of surgical intervention, hospital admissions and improving the quality of life of subjects with Charcot foot. Bisphosphonates may improve the healing of Charcot foot by reducing skin temperature and disease activity of Charcot foot, when applied in addition to standard interventions to control the position and shape of the foot.

Abstract: Podiatrists regularly use scalpels in the management of foot pathologies, yet the teaching and learning of these skills can be challenging. The use of 3D printed foot models presents an opportunity for podiatry students to practice their scalpel skills in a relatively safe, controlled risk setting, potentially increasing confidence and reducing associated anxiety. This study evaluated the use of 3D printed foot models on podiatry students’ anxiety and confidence levels and explored the fidelity of using 3D foot models as a teaching methodology. Multiple study designs were used. A repeated measure trial evaluated the effects of a 3D printed foot model on anxiety and confidence in two student groups: novice users in their second year of podiatry studies (n = 24), and more experienced fourth year students completing a workshop on ulcer management (n = 15). A randomised controlled trial compared the use of the 3D printed foot models (n = 12) to standard teaching methods (n = 15) on students’ anxiety and confidence in second year students. Finally, a focus group was conducted (n = 5) to explore final year student’s perceptions of the fidelity of the foot ulcer models in their studies. The use of 3D printed foot models increased both novice and more experienced users’ self-confidence and task self-efficacy however, cognitive and somatic anxiety was only reduced in the experienced users. All changes were considered large effects. In comparison to standard teaching methods, the use of 3D printed foot models had similar decreases in anxiety and increases in confidence measures. Students also identified the use of 3D foot models for the learning of scalpel skills as ‘authentic’ and ‘lifelike’ and led to enhanced confidence prior to assessment of skills in more high-risk situations. Podiatry undergraduate programs should consider using 3D printed foot models as a teaching method to improve students’ confidence and reduce their anxiety when using scalpels, especially in instances where face-to-face teaching is not possible (e.g., pandemic related restrictions on face-to-face teaching).

Abstract: Barefoot impressions collected from crime scenes can be used in forensic analysis. The reliability of the measurement method employed during comparison of these foot impressions is paramount to prevent incorrect conclusions being made. A number of methods of obtaining measurements from barefoot impressions have been described in the research literature however there has been no comprehensive review of their reliability. Therefore, the aim of this systematic review was to determine the reliability of measurements used to describe footprint morphology obtained from static and dynamic barefoot impressions. Four electronic databases were searched from inception to 23 November 2017. Eligible studies were required to report either the test-retest, intra or inter-rater reliability of measurements taken from barefoot impressions for the purposes of identification or classification of foot morphology. Methodological quality was assessed using the COSMIN checklist. Eleven studies were identified that reported the reliability of 10 measurements (Reel method, arch index, Chippaux-Smirak index, footprint angle, Staheli index, contact area, Martirosov's K index, toe score and metatarsal ridge-to-toe measurement). High intra-rater reliability has been established for the Reel method (ICC=0.98-0.99), arch index (ICC=0.96-0.99), Chippaux-Smirak index (ICC=0.98-0.99), footprint angle (ICC=0.97-0.98), Staheli index (ICC=0.98-0.99) and footprint index (ICC=0.96-0.97). High inter-rater reliability has been established for the Reel method (ICC=0.99) and footprint angle (ICC=0.99). Overall methodological quality was rated as 'Poor' to 'Fair'. The measurement developed by Reel et al. has both its intra- and inter-rater reliability established to be high. However, the findings of this review were unable to inform a recommendation of one specific technique based on reliability data due to a small body of research at this time. Furthermore, there is a lack of data on the reliability of footprint measurement and comparison techniques in real-world scenarios. Overall, the findings regarding reliability of the techniques covered in this systematic review are to be interpreted with caution due to the methodological quality of reliability testing conducted within the included studies.

Abstract: This systematic review and meta-analysis aimed to synthesise and clarify the effect of running-induced fatigue on impact loading during running. Eight electronic databases were systematically searched until April 2021. Studies that analysed impact loading over the course of a run, in adult runners free of medical conditions were included. Changes in leg stiffness, vertical stiffness, shock attenuation, peak tibial accelerations, peak ground reaction forces (GRF) and loading rates were extracted. Subgroup analyses were conducted depending on whether participants were required to run to exhaustion. Thirty-six studies were included in the review, 25 were included in the meta-analysis. Leg stiffness decreased with running-induced fatigue (SMD -0.31, 95% CI -0.52, -0.08, moderate evidence). Exhaustive and non-exhaustive subgroups were different for peak tibial acceleration (Chi

Abstract: The training of undergraduate and graduate-entry podiatry students in Australia and New Zealand includes practical sessions in a simulated and real-life clinical setting and Work Integrated Learning (WIL) comprising professional clinical placements. Student performance during WIL is evaluated by their Clinical Educators using clinical competency tools. Having a standardised and validated clinical assessment tool for WIL in podiatry would facilitate consistency in assessment, promote standardisation between programs, and ensure that all podiatry students are assessed against a set of criteria over the course of their clinical programs to the point of threshold clinical competency. Therefore, the aim of this study was to develop a series of consensus-based statements via Delphi technique as the first step towards developing guidelines to direct the assessment of podiatry students during WIL. This study used a three-round modified Delphi consensus method. A panel of 25 stakeholders was sought. Specifically, representation from each of the universities in Australia and New Zealand who provide entry level programs, Clinical Educators, podiatry student representatives, new podiatry graduates and consumers (podiatrists hiring new graduates). The survey for Round 1 aimed for consensus and consisted of five open-ended questions. Questions one to three asked respondents to nominate what they considered were the important elements that needed to be assessed for podiatry students undertaking WIL for: Clinical performance/skills, Communication and Professional behaviour, Question 4 asked respondents to identify further/other elements of importance, whilst Question 5 asked a) how these elements should be evaluated and b) how should overall competency and ability to progress within the program be determined. Round 2 and 3 aimed to gather agreement and the questions were based on the responses from previous rounds. Twenty-five participants agreed to participate, 17 females (68%) and eight males (32%). The panel consisted of 10 podiatry educators (40%), nine Clinical Educators (36%), two student representatives (8%), two new podiatry graduates (8%) and two consumers (8%). From the 25 recruited participants, 21 responded to Round one, 18 to Round two and 17 in Round three. At the conclusion of the Delphi survey, 55 statements had reached consensus or agreement. This Delphi study is the first of its kind for the podiatry profession to develop consensus-based statements regarding the assessment of WIL. Fifty-five statements pertinent to the assessment of WIL were identified. This is an important first step toward the development of a consistent WIL assessment tool which may be applied across entry-level podiatry programs across Australia and New Zealand.

Abstract: Ankle traumas are common presenting injuries to emergency departments in Australia and worldwide. The Ottawa Ankle Rules (OAR) are a clinical decision tool to exclude ankle fractures, thereby precluding the need for radiographic imaging in patients with acute ankle injury. Previous studies support the OAR as an accurate means of excluding ankle and midfoot fractures, but have included a paediatric population, report both the ankle and mid-foot, or are greater than 5 years old. This systematic review and meta-analysis aimed to update and assess the existing evidence of the diagnostic accuracy of the Ottawa Ankle Rule (OAR) acute ankle injuries in adults. A systematic search and screen of was performed for relevant articles dated 1992 to 2020. Prospective and retrospective studies documenting OAR outcomes by physicians to assess ankle injuries were included. Critical appraisal of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Outcomes related to psychometric data were pooled using random effects or fixed effects modelling to calculate diagnostic performance of the OAR. Between-study heterogeneity was assessed using the Higgins I2 test, with Spearman’s correlation test for threshold effect. From 254 unique studies identified in the screening process, 15 were included, involving 8560 patients from 13 countries. Sensitivity, specificity, negative likelihood ratio, positive likelihood ratio and diagnostic odds ratio were 0.91 (95% CI, 0.89 to 0.92), 0.25 (95% CI, 0.24 to 0.26), 1.47 (95% CI, 1.11 to 1.93), 0.15 (95% CI, 0.72 to 0.29) and 10.95 (95% CI, 5.14 to 23.35) respectively, with high between-study heterogeneity observed (sensitivity: I2 = 94.3%, p 0.01 specificity: I2 = 99.2%, p 0.01). Most studies presented with low risk of bias and concern regarding applicability following assessment against QUADAS-2 criteria. Application of the OAR is highly sensitive and can correctly predict the likelihood of ankle fractures when present, however, lower specificity rates increase the likelihood of false positives. Overall, the use of the OAR tool is supported as a cost-effective method of reducing unnecessary radiographic referral, that should improve efficiency, lower medical costs and reduce waiting times.

Abstract: Evaluation of psychomotor skills is undertaken in a number of broad contexts. This includes testing of health professional populations as a measure of innate ability, to evaluate skill acquisition, or to compare professions. However, the use of psychomotor tests is frequently confounded by a lack of understanding of a particular tool's psychometric properties, strengths, and weaknesses. To identify and appraise the most commonly used tests on health professional populations, 86 articles were reviewed and the top nine tests identified. Few tests have had sufficient validity or reliability testing on health professionals. Based on the evidence available, use of the Grooved Pegboard Test, the Purdue Pegboard Test, or the Finger Tapping Test is recommended for the evaluation of dexterity in a health professional population however, this choice may be dependent on the task(s) to which findings are generalised. More rigorous evaluation of validity and other psychometric properties is required.
