A randomised controlled trial of sensory awareness training and additional motor practice for learning scalpel skills in podiatry students
Ryan S Causby, Michelle N McDonnell, Lloyd Reed and Susan L Hillier
BMC Medical Education 201616:309

Background
The process of using a scalpel, like all other motor activities, is dependent upon the successful integration of afferent (sensory), cognitive and efferent (motor) processes. During learning of these skills, even if motor practice is carefully monitored there is still an inherent risk involved. It is also possible that this strategy could reinforce high levels of anxiety experienced by the student and affect student self-efficacy, causing detrimental effects on motor learning. An alternative training strategy could be through targeting sensory rather than motor processes.

Methods
Second year podiatry students who were about to commence learning scalpel skills were recruited. Participants were randomly allocated into sensory awareness training (Sensory), additional motor practice (Motor) or usual teaching only (Control) groups. Participants were then evaluated on psychological measures (Intrinsic Motivation Inventory) and dexterity measures (Purdue Pegboard, Grooved Pegboard Test and a grip-lift task).

Results
A total of 44 participants were included in the study. There were no baseline differences or significant differences between the three groups over time on the Perceived Competence, Effort/ Importance or Pressure/ Tension, psychological measures. All groups showed a significant increase in Perceived Competence over time (F1,41 = 13.796, p = 0.001). Only one variable for the grip-lift task (Preload Duration for the non-dominant hand) showed a significant difference over time between the groups (F2,41 = 3.280, p = 0.038), specifically, Motor and Control groups.

Conclusions
The use of sensory awareness training, or additional motor practice did not provide a more effective alternative compared with usual teaching. Further research may be warranted using more engaged training, provision of supervision and greater participant numbers.

A qualitative evaluation of scalpel skill teaching of podiatry students

Journal of Foot and Ankle Research 2017 10:21

Background
Degrees in health disciplines need a balance of theoretical knowledge and sufficient clinical practice to meet registration requirements, in particular those requiring specialist skills such as the use of scalpels and other small instruments, such as podiatry. However, despite this requirement there is a scarcity of literature and research to inform teaching of these particular manual clinical skills. Therefore, the aims of this study were to determine the current approaches being used to teach manual skills, in particular scalpel skills, in university podiatry programs in Australia and New Zealand, and to explore what issues, challenges and innovations exist.

Methods
A qualitative study, consisting of semi-structured interviews with staff at eight university podiatry programs in Australia and New Zealand was undertaken to determine how these skills are taught and evaluated, and how poor performers are managed. A conventional content analysis technique was used to analyse and code interview data, with the resultant categories reported.

Results
Approaches to teaching manual clinical skills, in particular scalpel skills, appear to be consistent between university programs in Australia and New Zealand in utilising didactic-style content, demonstration, physical practice on inanimate objects and real skin, and often the use of supplementary audio-visual material. The main reported differences between programs were in methods and processes of practice, with controversy regarding the use of inanimate objects versus real skin for practice.

Conclusions
Despite a lack of research and literature surrounding this topic, the approach to teaching is relatively consistent between programs with greatest disparity being the structure and duration of practice. Key issues for teaching staff in teaching manual skills were students’ clinical exposure, motivation, levels of anxiety and dexterity.

Teaching of Manual Clinical Skills in Podiatric Medicine.
Ryan S. Causby, Lloyd Reed, Michelle N. McDonnell, and Susan L. Hillier
Journal of the American Podiatric Medical Association: March 2018, Vol. 108, No. 2, pp. 158-167.

In the podiatric medicine profession, there are a variety of manual tasks that require precision and skill beyond what would be usually expected in everyday living. It is the expectation of employers, regulatory bodies, and the public that graduating podiatric physicians sufficiently meet certain minimum competencies for that profession, including those for manual skills. However, teaching and evaluation methods seem to be inconsistent between countries, institutions, and programs. This may be the consequence of uncertainty regarding the safest and most effective methods to do so. A review of available international literature pertaining to psychomotor learning across a range of health professions was undertaken. As a result of this broad review, we present herein the available evidence and make recommendations for the teaching of psychomotor skills in the podiatric medicine profession. Specific aspects considered important include methods of teaching, practice, and feedback.

Measuring dexterity in the podiatrist population: a cross-sectional comparison of novice students and experienced podiatrists
Ryan Causby, Michelle McDonnell, Lloyd Reed and Susan Hillier
BMC Medical Education201818:181

Background
There is no ‘gold-standard’ for the evaluation of dexterity for the health professional or podiatrist populations. This has resulted in a broad array of generalised tests to evaluate dexterity. Thus, the aim was to determine which objective generalised dexterity tests are best suited to evaluating dexterity in a podiatry student population.

Methods
A cohort of Novice podiatry students and Experienced podiatrists were recruited and evaluated on a battery of dexterity tests selected to evaluate a variety of different elements. Group differences were evaluated statistically and regression undertaken on significant test outcomes.

Results
A total of 108 participants were recruited with 54 participants in each of the Novice and Experienced groups. Five of the eight tests were able to discriminate dexterous ability of participants in the Novice and Experienced groups. These included the Grip-lift task, GPT, P-MVC, G-MVC and the AsTex® sensory discrimination test. These tests comprised a total of 11 significant dependent variables (p < 0.05). From the test battery, outcomes were able to predict 79% of the group membership. Age and experience did not explain within-group variability for the Experienced group.

Conclusion
Whilst the Experienced group displayed superior performance in strength and speed, the Novice group showed superior coordination and sensory ability. From these findings, we would recommend that outcomes from the Grooved Pegboard Test, Grip-lift task, Grip Strength test and Pinch Grip strength test be used to evaluate elements of dexterity in this population.
