Foot orthoses for people with rheumatoid arthritis, involving quantitative and qualitative outcomes : protocol for a randomised controlled trial

Introduction: Rheumatoid arthritis (RA) involves changes to foot structure and function, and there is an association between RA and foot pain. This pain affects those patient’s physical activity and experience of daily living. While there is clinical evidence for the value of foot orthoses (FO) on foot pain, there is a wide range of FO available and there is little evidence on the relative benefits of one orthoses type over another, especially in terms of their impact on physical activity and associated well-being. The aim of this study is to compare physical activity, general and foot health and foot health experiences in people with RA when wearing three different types of FO. Methods and analysis: A randomised controlled trial with three arms will compare the effects of (1) custom FO made using a direct adaptation technique, (2) custom FO made through a digital design and production process and (3) prefabricated orthoses. The primary outcome is physical activity measured using a GENEActiv bracelet. Secondary outcomes will be pain, function and disability and associated foot and general health evaluated using existing questionnaires. Semistructured interviews will identify patients’ experiences of the orthoses and living with RA. Ethics and dissemination: The study has been approved by the Portal de Ética de la Investigación Biomédica de Andalucía ethical committee (SPAR-001). The results will be disseminated regardless of the magnitude or direction of effect. Trial registration number: NCT03170947; Pre-results

The biopsychosocial-digital continuum of foot orthosis practice and research : the VALUATOR model

Foot orthoses have been used for decades despite uncertainty surrounding their therapeutic efficacy. Orthoses have been used exclusively to affect neuro-biomechanical input and outcome variables, however, there is emerging evidence that therapeutic efficacy may be affected by a psychological stimulus. Critical appraisal of the literature highlights that there is no holistic model upon which foot orthosis practice is taught, practised nor investigated. This paper introduces a conceptual model of foot orthosis practice (Value Based Foot Orthosis Practice (VALUATOR) model) that embraces a broader range of factors that are pertinent to orthosis practice, incorporating contemporary health service behaviours and values into orthosis practice for the first time. Within the VALUATOR model, foot orthosis design and clinical value is considered along a bio-psycho-social-digital continuum that reflects the reality of foot orthosis practice. The model contextualises the variable outcomes that are observed in research and practice within 6 key areas: 1) value, 2) person-centered approach, 3) zone of optimal bio-psycho-social stress, 4) bio-psycho-social assessment, 5) monitoring, 6) primary and secondary clinical strategies. The VALUATOR model is targeted at students, lecturers, scientists and practitioners and includes carefully chosen terminology to support a robust basis for educational and scientific discussion. It is believed that it provides a contemporary viewpoint and a structured conceptual metaphor that builds on existing evidence from a wide range of sources, invites constructive intellectual debate, and is anchored in the experiences of practitioners too. Stress testing the VALUATOR model will help determine its model and support further developments and evolution of orthotic practice in a evidence based way

Conservative treatment for acute ankle sprain : a systematic review

The aim was to identify conservative treatments available for acute ankle sprain and to evaluate their effectiveness with respect to pain relief and short-term recovery of functional capacity. A systematic review of the relevant literature was conducted via a data search of the PROSPERO, PubMed, Scopus, CINAHL, PyscINFO and SPORTDiscus databases, from inception until December 2019, focusing on randomised control trial studies. Two of the authors independently assessed the quality of each study located and extracted the relevant data. The quality of each paper was assessed using the Cochrane risk of bias tool included in RevMan 5. In all, 20 studies met the inclusion criteria. In terms of absence of bias, only nine papers were classed as “high quality”. Studies (75%) were of low quality in terms of the blinding of participants and personnel and uncertainty in blinding of outcome assessment and all presented one or more other forms of bias. Despite the generally low quality of the studies considered, it can be concluded that conservative treatment for acute ankle sprain normally achieves pain relief and rapidly improved functionality. Research based on higher-quality study designs and procedures would enable more definitive conclusions to be drawn

A conceptual framework for contemporary professional foot care practice : ''The value based digital foot care framework''

Background: A small minority of countries around the globe have podiatry as a recognized profession, hence, there are considerable differences among these countries when it comes to the curricula, the duration of training and legislation regulating the profession. The growth in research led evidence based practice, and the emerging digital landscape of health care practice, occur alongside trends in disease and health behaviours that strongly impact on foot health. As such, the changing complex role of the podiatrist requires critical reflection on current frameworks of practice and whether they are fit for purpose. This commentary presents a conceptual framework which sets the scene for further development of concepts in a podiatry context, reflecting contemporary health care beliefs and the changing expectations of health care and society. The proposed conceptual framework for podiatry practice utilizes the metaphor of an electronic circuit to reflect the vast and complex interconnections between factors that affect practice and professional behaviours. The framework helps in portraying and defining drivers of practice, actual practice as well potential barriers for current and future practice. The circuit emphasis the interconnectedness/interaction of three clusters: 1) internal factors, 2) interaction factors, 3) external factors. Conclusion: Whatever promise this new framework holds, it will only be realised through conscious development of community consensus, respectful dialogue, constructive critical appraisal, and maintaining passion and focus on improving the health of people with foot related problems

A qualitative study exploring the experiences and perceptions of patients with rheumatoid arthritis before and after wearing foot orthoses for 6 months

Foot pathology in people with rheumatoid arthritis (RA) can have a psychosocial impact, but interventions such as foot orthoses can reduce foot pain, improving physical activity and quality of life. A previous meta-analysis concluded that foot orthoses can relieve pain and disability and enhance patient's well-being. The aim of this study was to explore the experiences of people with RA, before and after wearing foot orthoses for 6 months. Data were collected through digital recordings of semi-structured interviews carried out before and after wearing foot orthoses for 6 months. A thematic analysis of the transcripts was used to identify themes. Six female participants with RA wore foot orthoses for 6 months in Spain. The mean disease duration was more than 10 years. The findings showed three key themes emerged from the data: (1) improvement in physical activity; (2) footwear… a tricky situation and (3) social implications of RA feet. It is concluded that patients reported that wearing foot orthoses can have a positive impact on physical activity and improve general wellness and quality of life. However, to achieve the potential positive benefits, people with RA also needed to wear suitable footwear (defined as footwear which accommodates both the foot and the insole while maintaining the fit and function of the shoe). Despite the positive impact of wearing orthoses, participants stated that complexities of finding suitable footwear acted as a blocker. [Abstract copyright: © 2021 John Wiley & Sons Ltd.

Die Druckmessplattform als klinisch-diagnostisches Instrument zur Analyse der Fußstatik nach dem Foot Posture Index

Background: The foot posture index is a static measurement that splits up the foot posture into neutral, pronatus and supinatus. However, the relation between the foot posture and the plantar pressure standards is not well known. For this, the objective of this research is to check the relationship between the foot posture and plantar pressure standard. Subjects and Material: 144 participants (101 women and 43 men), mean age 25.4 +/- 6.3 years, were measured for the FPI. The pedobarometric measurement was made with the plantar pressure platform, we measured total surface (cm(2)), mean pressure (kPa) and maximum pressure (kPa), these measurements were correlated with the FPI measurements. Results: 288 feet were analysed with regard to the correlation between point 5 of FPI (medial arch height) and the plantar surface total area (p = 0.038): lower arch height and supinated foot are related to the maximum pressure points with p = 0.029. The total contact surface can be determined with the final score of the FPI, the scores of FPI 3, 5 and 6 FPI (r(2) = 0.059, p < 0.001) with a 5.9% prediction. Conclusion: The supinatus foot is correlated statistically significantly through the maximum pressure and the plantar surface with the pronatus foot
