BackgroundOver 1 in 3 older people with diabetes sustain a fall each year. Postural instability has been identified as independent risk factor for falls within people with Diabetic Peripheral Neuropathy (DPN). People with DPN, at increased risk of falls, are routinely required to wear offloading insoles, yet the impact of these insoles on postural stability and postural control is unknown. The aim of this study was to evaluate the effect of a standard offloading insole and its constituent parts on the balance in people with DPN.MethodsA random sample of 50 patients with DPN were observed standing for 3 × 30 s, and stepping in response to a light, under five conditions presented in a random order; as defined by a computer program; 1) no insole, 2) standard diabetic: a standard offloading insole made from EVA/poron®, and three other insoles with one design component systematically altered 3) flat: diabetic offloading insole with arch fill removed, 4) low resilient memory: diabetic offloading insole with the cover substituted with low resilience memory V9, 5) textured: diabetic offloading insole with a textured PVC surface added (Algeos Ltd). After each condition participants self-rated perceived steadiness.ResultsInsole design effected static balance and balance perception, but not stepping reaction time in people with DPN. The diabetic and memory shaped insoles (with arch fill) significantly increased centre of pressure velocity (14 %, P = 0.006), (13 %, P = 0.001), and path length (14 %, P = 0.006), (13 %, P = 001), when compared to the no insole condition. The textured shaped and flat soft insole had no effect on static balance when compared to the no insole condition (P > 0.05).ConclusionInsoles have an effect on static balance but not stepping reaction time. This effect is independent of neuropathy severity. The addition of a textured cover seems to counter the negative effect of an arch fill, even in participants with severe sensation loss. Static balance is unaffected by material softness or resilience. Current best practice of providing offloading insoles, with arch fill, to increase contact area and reduce peak pressure could be making people more unstable. Whilst flat, soft insoles maybe the preferable design option for those with poor balance. There is a need to develop an offloading insole that can reduce diabetic foot ulcer risk, without compromising balance.

The aim of this systematic review was to identify the best footwear and insole design features for offloading the plantar surface of the foot to prevent foot ulceration in people with diabetic peripheral neuropathy. We searched multiple databases for published and unpublished studies reporting offloading footwear and insoles for people with diabetic neuropathy and nonulcerated feet. Primary outcome was foot ulcer incidence; other outcome measures considered were any standardized kinetic or kinematic measure indicating loading or offloading the plantar foot. Fifty‐four studies, including randomized controlled studies, cohort studies, case‐series, and a case‐controlled and cross‐sectional study were included. Three meta‐analyses were conducted and random‐effects modelling found peak plantar pressure reduction of arch profile (37 kPa (MD, −37.5; 95% CI, −72.29 to −3.61; P < .03), metatarsal addition (35.96 kPa (MD, −35.96; 95% CI, −57.33 to −14.60; P < .001) and pressure informed design 75.4 kPa (MD, −75.4 kPa; 95% CI, −127.4 to −23.44 kPa; P < .004).The remaining data were presented in a narrative form due to heterogeneity. This review highlights the difficulty in differentiating the effect of different insole and footwear features in offloading the neuropathic diabetic foot. However, arch profiles, metatarsal additions and apertures are effective in reducing plantar pressure. The use of pressure analysis to enhance the effectiveness of the design of footwear and insoles, particularly through modification, is recommended.

Background With growing recognition of the importance of research in allied healthcare, the new Health Education England (HEE) research strategy articulates a need to transform Allied Health Professional (AHP) identities, culture and roles. An understanding of current AHP research capacity and culture is first required. Methods A cross-sectional survey targeted AHPs working in NHS health and social care settings across the United Kingdom. The validated Research Capacity and Culture tool was modified and distributed through research and professional networks. Aggregate median scores for perceived research success were categorised as adequate, more than, or less than adequate. Results Of 3344 participants, 3145 identified as HEE-defined AHPs. Individual- and organisation-level research success was perceived as adequate (median scores 4 (IQR 2 to 6); 4 (IQR 2 to 7) respectively). Team-level research success was rated less than adequate (median score 2 (IQR 1–5)). Conclusions In the UK, AHPs working in NHS health and social care perceive individual and organisational level research skill/success to be adequate. In contrast, inadequacies in research skill/support at team level were exposed, which may hinder successful integration of allied health research into everyday health and social care practice. Recommendations are made with reference to the HEE AHP research strategy.

Background Diabetes related foot complications are increasing in complexity, frequency and cost. The application of self-management strategies can reduce the risk of individuals developing foot complications. The type, range and nature of the literature focusing on interventions that support patients with diabetic foot self-management is unknown. This scoping review aimed to i) identify self-management actions and risky behaviour avoidance strategies within interventions, ii) map the theoretical functions through which these behaviour change interventions have an effect, iii) display gaps in the research. Methodology Arksey and Malley’s (2003) 5 stage framework was followed to conduct the scoping study. This methodological framework was selected because it was developed specifically for scoping reviews and therefore offered clear methodological distinction from systematic review methodology. . Databases were searched from inception of the project until June 2020 supplemented by hand searching of reference lists. In total 988 papers were identified. These were independently screened by three reviewers, identifying 19 eligible papers. Data extraction and charting of data was independently conducted by three reviewers to identify study characteristics, self-management actions and risky behaviours. Data was charted against the COM-B (capability, opportunity, motivation, behaviour) model of behaviour to determine intervention function. Results In total 25 different foot self-management actions and risk behaviours were classified into three themes; routine self-management, trauma avoidance and warning signs and actions. Inspect feet daily received the most attention. The majority of interventions focused on knowledge and skills, but overlooked taking action and decision making. Intervention mapping identified four primary intervention functions (education, persuasion, training and enablement) used to address deficits in capability, opportunity and motivation that positively improved foot self-management behaviour. No studies targeted first ulcer prevention, and most either did not measure or improve foot health outcomes. Conclusion This review charted the evidence for interventions promoting diabetic foot self-management through a theoretical behaviour change perspective. A core set of behaviour change activities and intervention functions associated with positive changes in behaviour were identified. This information will provide researchers with a useful basis for developing self-management interventions.
