RESUMO

BACKGROUND AND AIMS: Motivational approaches may help target the psychological aspects of self-care, improving adherence to good practices in individuals with diabetes. The present study was designed to test the feasibility and effectiveness of a psychoeducational program for diabetic foot prevention or disease progression. METHODS AND RESULTS: Eighty-one subjects with or at high risk of foot ulcer development entered a program consisting of six 120-min group sessions, conducted by a podiatrist and an expert in psycho-education. Occurrence/recurrence of lesions in a 3-year follow-up was compared with 172 cases with similar risk score (IWGDF score 2019), receiving education at any 6-month podiatric visit (standard-of-care). Motivation to self-care and competence were assessed by specific questionnaires. The experimental program increased adherence to follow-up. The prevalence of foot lesions was higher at baseline and was remarkably reduced at any time-point in patients attending the psychoeducational program, whereas it remained relatively stable in standard care (around 10% of cases). The cumulative incidence was lower in the psychoeducational program (13.2, 95% CI 9.2-18.0 per 100 patient-year vs. 26.1; 95% CI 22.1-30.2); time to new lesions was increased (P = 0.022). Cox proportional hazard analysis confirmed an overall reduction of lesions in the psychoeducational program (HR 0.34; 95% CI 0.18-0.66; P < 0.001), after adjustment for confounders. The program was associated with significant changes in competence and motivation to self-care. CONCLUSION: A psychoeducational approach is both feasible and effective to support patients with diabetes at high risk of first or recurrent foot lesions, increasing their adherence to self-care practices.

RESUMO

BACKGROUND: Measurements of plantar loading reveal foot-to-floor interaction during activity, but information on bone architecture cannot be derived. Recently, cone-beam computer tomography (CBCT) has given visual access to skeletal structures in weight-bearing. The combination of the two measures has the potential to improve clinical understanding and prevention of diabetic foot ulcers. This study explores the correlations between static 3D bone alignment and dynamic plantar loading. METHODS: Sixteen patients with diabetes were enrolled (group ALL): 15 type 1 with (N, 7) and without (D, 8) diabetic neuropathy, and 1 with latent autoimmune diabetes. CBCT foot scans were taken in single-leg upright posture. 3D bone models were obtained by image segmentation and aligned in a foot anatomical reference frame. Absolute inclination and relative orientation angles and heights of the bones were calculated. Pressure patterns were also acquired during barefoot level walking at self-selected speed, from which regional peak pressure and absolute and normalised pressure-time integral were worked out at hallux and at first, central and fifth metatarsals (LOAD variables) as averaged over five trials. Correlations with 3D alignments were searched also with arch index, contact time, age, BMI, years of disease and a neuropathy-related variable. RESULTS: Lateral and 3D angles showed the highest percentage of significant (p < 0.05) correlations with LOAD. These were weak-to-moderate in the ALL group, moderate-to-strong in N and D. LOAD under the central metatarsals showed moderate-to-strong correlation with plantarflexion of the 2nd and 3rd phalanxes in ALL and N. LOAD at the hallux increased with plantarflexion at the 3rd phalanx in ALL, at 1st phalanx in N and at 5th phalanx in D. Arch index correlated with 1st phalanx plantarflexion in ALL and D; contact time showed strong correlation with 2nd and 3rd metatarsals and with 4th phalanx dorsiflexion in D. CONCLUSION: These preliminary original measures reveal that alteration of plantar dynamic loading patterns can be accounted for peculiar structural changes of foot bones. Load under the central metatarsal heads were correlated more with inclination of the corresponding phalanxes than metatarsals. Further analyses shall detect to which extent variables play a role in the many group-specific correlations.
