    Study protocol for a randomized controlled trial on the effect of the Diabetic Foot Guidance System (SOPeD) for the prevention and treatment of foot musculoskeletal dysfunctions in people with diabetic neuropathy: the FOotCAre (FOCA) trial I
    (2020) FERREIRA, J. S. S. P.; CRUVINEL JUNIOR, R. H.; SILVA, E. Q.; VERISSIMO, J. L.; MONTEIRO, R. L.; PEREIRA, D. S.; SUDA, E. Y.; SARTOR, C. D.; SACCO, I. C. N.
    Background This study is part of a series of two clinical trials. Taking into account the various musculoskeletal alterations of the foot and ankle in people with diabetic peripheral neuropathy (DPN) and the need for self-care to avoid more serious dysfunctions and complications, a self-manageable exercise protocol that focuses on strengthening the foot muscles is presented as a potentially effective preventive method for foot and gait complications. The aim of this trial is to investigate the effect of a customized rehabilitation technology, the Diabetic Foot Guidance System (SOPeD), on DPN status, functional outcomes and gait biomechanics in people with DPN. Methods/design Footcare (FOCA) trial I is a randomized, controlled and parallel two-arm trial with blind assessment. A total of 62 patients with DPN will be allocated into either a control group (recommended foot care by international consensus with no foot exercises) or an intervention group (who will perform exercises through SOPeD at home three times a week for 12 weeks). The exercise program will be customized throughout its course by a perceived effort scale reported by the participant after completion of each exercise. The participants will be assessed at three different times (baseline, completion at 12 weeks, and follow-up at 24 weeks) for all outcomes. The primary outcomes will be DPN symptoms and severity classification. The secondary outcomes will be foot-ankle kinematics and kinetic and plantar pressure distribution during gait, tactile and vibration sensitivities, foot health and functionality, foot strength, and functional balance. Discussion As there is no evidence about the efficacy of rehabilitation technology in reducing DPN symptoms and severity or improving biomechanical, clinical, and functional outcomes for people with DPN, this research can contribute substantially to clarifying the therapeutic merits of software interventions. We hope that the use of our application for people with DPN complications will reduce or attenuate the deficits caused by DPN. This rehabilitation technology is freely available, and we intend to introduce it into the public health system in Brazil after demonstrating its effectiveness.

    Instrumentos de avaliação para limitações funcionais associadas à instabilidade crônica de tornozelo: uma revisão sistemática da literatura
    (2012) SUDA, Eneida Yuri; COELHO, Ana Tereza
    Ankle instability is defined as the tendency of the ankle to ""give way"" and suffer recurrent sprains after a lateral ankle sprain. Since the presence of instability is defined by means of subjects' complaints, it has a subjective characteristic it is important to identify the best assessment tool to determine its presence and/or severity. The purpose of this study was to systematically review assessment instruments designed for patients with chronic ankle instability. A computerized literature search was performed in the databases of PubMed, Embase, VHL, LILACS and SciELO to identify eligible instruments. Five studies were included and presented five different instruments - Foot and Ankle Disability Index (FADI), Ankle Joint Functional Assessment Tool (AJFAT), Foot and Ankle Ability Measure (FAAM), Ankle Joint Functional Assessment Tool (AII) e Cumberland Ankle Instability Tool (CAIT). There were instruments that can detect functional limitations in subjects with functional ankle instability but that are not reliable to detect this condition. There is still a need for further clinimetric studies in order to validate these tools to obtain an effective and complete evaluation of the functional instability of the ankle.

    Recognition of Foot-Ankle Movement Patterns in Long-Distance Runners With Different Experience Levels Using Support Vector Machines
    (2020) SUDA, Eneida Yuri; WATARI, Ricky; MATIAS, Alessandra Bento; SACCO, Isabel C. N.
    Running practice could generate musculoskeletal adaptations that modify the body mechanics and generate different biomechanical patterns for individuals with distinct levels of experience. Therefore, the aim of this study was to investigate whether foot-ankle kinetic and kinematic patterns can be used to discriminate different levels of experience in running practice of recreational runners using a machine learning approach. Seventy-eight long-distance runners (40.7 +/- 7.0 years) were classified into less experienced (n= 24), moderately experienced (n= 23), or experienced (n= 31) runners using a fuzzy classification system, based on training frequency, volume, competitions and practice time. Three-dimensional kinematics of the foot-ankle and ground reaction forces (GRF) were acquired while the subjects ran on an instrumented treadmill at a self-selected speed (9.5-10.5 km/h). The foot-ankle kinematic and kinetic time series underwent a principal component analysis for data reduction, and combined with the discrete GRF variables to serve as inputs in a support vector machine (SVM), to determine if the groups could be distinguished between them in a one-vs.-all approach. The SVM models successfully classified all experience groups with significant crossvalidated accuracy rates and strong to very strong Matthew's correlation coefficients, based on features from the input data. Overall, foot mechanics was different according to running experience level. The main distinguishing kinematic factors for the less experienced group were a greater dorsiflexion of the first metatarsophalangeal joint and a larger plantarflexion angles between the calcaneus and metatarsals, whereas the experienced runners displayed the opposite pattern for the same joints. As for the moderately experienced runners, although they were successfully classified, they did not present a visually identifiable running pattern, and seem to be an intermediate group between the less and more experienced runners. The results of this study have the potential to assist the development of training programs targeting improvement in performance and rehabilitation protocols for preventing injuries.

    Predictive Effect of Well-Known Risk Factors and Foot-Core Training in Lower Limb Running-Related Injuries in Recreational Runners: A Secondary Analysis of a Randomized Controlled Trial
    (2022) SUDA, Eneida Yuri; WATARI, Ricky; MATIAS, Alessandra B.; TADDEI, Ulisses T.; SACCO, Isabel C. N.
    Background: Running carries the risk of several types of running-related injuries (RRIs), especially in the lower limbs. The variety of risk factors and the lack of strong evidence for several of these injury risks hinder the ability to draw assertive conclusions about them, hampering the implementation of effective preventive strategies. Because the etiology of RRIs seems to be multifactorial, the presence of RRI risk factors might influence the outcome of therapeutic strategies in different ways. Thus, further investigations on how risk and protective factors influence the incidence and prevention of RRIs should be conducted. Purpose: To investigate the predictive effect of well-known risk factors and 1 protective factor-foot-core training-on the incidence of lower limb RRIs in recreational runners. Study Design: Cohort study; Level of evidence, 2. Methods: Middle- and long-distance recreational runners (N = 118) were assessed at baseline and randomly allocated to either an intervention group (n = 57) or a control group (n = 61). The intervention group underwent an 8-week (3 times/wk) foot-core training program. Participants were followed for a year after baseline assessment for the occurrence of RRIs. Logistic regression with backward elimination of variables was used to develop a model for prediction of RRI in recreational runners. Candidate predictor variables included age, sex, body mass index, years of running practice, number of races, training volume, training frequency, previous RRI, and the foot-core exercise training. Results: The final logistic regression model included 3 variables. As previously shown, the foot-core exercise program is a protective factor for RRIs (odds ratio, 0.40; 95% CI, 0.15-0.98). In addition, older age (odds ratio, 1.07; 95% CI, 1.00-1.14) and higher training volume (odds ratio, 1.02; 95% CI, 1.00-1.03) were risk factors for RRIs. Conclusion: The foot-core training was identified as a protective effect against lower limb RRI, which can be negatively influenced by older age and higher weekly training volume. The predictive model showed that RRIs should be considered a multivariate entity owing to the interaction among several factors. Registration: NCT02306148 (ClinicalTrials.gov identifier).

    Effects of a Home-Based Foot-Ankle Exercise Program with Educational Booklet for Foot Dysfunctions in People with Diabetic Neuropathy: Results of the FOCA-II Randomized Controlled Clinical Trial
    (2023) SILVA, erica Q.; VERISSIMO, Jady L.; FERREIRA, Jane S. S. P.; CRUVINEL-JUNIOR, Ronaldo H.; MONTEIRO, Renan L.; SUDA, Eneida Y.; SACCO, Isabel C. N.
    Exercise rehabilitation and education are important strategies for preventing the progression of diabetic neuropathy-related musculoskeletal deficits. The purpose of this randomized controlled trial was to investigate the effect of an 8-week home-based foot-ankle exercise program using an educational booklet on clinical outcomes (foot muscle strength and functionality; functional balance; diabetic neuropathy symptoms and severity; tactile and vibratory sensitivities; plantar pressure distribution; and foot-ankle, knee, and hip biomechanics during gait). Fifty participants with neuropathy were randomly allocated into an intervention group (59.1 +/- 6.4 years, 23.5 +/- 4.8 kg/m(2), males = 6, females = 19) that performed the exercises for 8 weeks and a control group (56.5 +/- 9.4 years, 22.9 +/- 3.6 kg/m(2), males = 5, females = 20) that received usual care recommendations. Generalized estimating equation method and intention-to-treat approaches were adopted. No significant differences were found for any clinical outcome after 8 weeks. Heel contact area increased in the intervention group compared to controls (p = 0.043, mean difference = 2.7 cm) and heel peak pressure was increased in controls compared to intervention (group effect p = 0.020, mean difference = -64.16 kPa) at 8 weeks. Controls showed increased joint moments for the hip at heel strike (p = 0.007) and for the knee and hip at push off over 8 and 16 weeks (p < 0.001 and p = 0.009, respectively). Although the intervention is easy to perform and showed a good adherence (72%), home-based foot-ankle exercise programs are unlikely to sufficiently modify the main risk factors related to foot ulcers and to change foot-ankle kinematics and kinetics.

    Impact of diabetic neuropathy severity on foot clearance complexity and variability during walking
    (2019) SUDA, Eneida Yuri; MATIAS, Alessandra Bento; BUS, Sicco A.; SACCO, Isabel C. N.
    Background: The control of foot trajectory during swing phase is important to achieve safe clearance with the ground. Complexity of a physiological control system arises from the interaction of structural units and regulatory feedback loops that operate to enable the organism to adapt to a non-static environment. Diabetic polyneuropathy (DPN) impairs peripheral feedback inputs and alters ankle control during gait, which might affect toe clearance (ToC) parameters and its complexity, predisposing DPN-subjects to tripping and falling. Research question: How do different DPN-severity degrees change ToC trajectory and minimum ToC, and its complexity during gait of diabetic subjects? Methods: 15 healthy controls and 69 diabetic subjects were assessed and classified into DPN-severity degrees by an expert fuzzy model: absent (n = 26), mild (n = 21) and severe (n = 22). Three-dimensional kinematics was measured during comfortable walking. ToC was the minimum vertical distance between the marker placed at the first metatarsal head and the ground during swing. Mean ToC, ToC standard deviation (SD) between trials, and sample entropy (SaEn) and standard deviation (SD) of ToC trajectory were calculated from the ToC temporal series. ANOVA and ANCOVA (with the walking speed as the covariate) and Bonferroni pairwise post-hoc tests (P < 0.05) were used to compare groups. Results: Mean ToC and ToC SD did not show differences between groups (ANCOVA F = 0.436; df = 3; P = 0.705; F = 1.719; df = 3; P = 0.170, respectively). ToC trajectory SD also did not show differences between groups (ANCOVA F = 3.98; df = 3; P = 0.755). Severe-DPN subjects showed higher ToC_Traj_SaEn than controls (ANCOVA F = 2.60; df = 3; P = 0.05). Significance: Severe-DPN subjects showed a more complex pattern of overall foot-ankle trajectory in swing phase in comparison to controls, although did not present lower minimum ToC values. The higher complexity of ToC might lead to an increase in the motor system output (more strategies, increase in variability), resulting in a more unstable system and selected motor strategies.

    Effects of Foot-Core Training on Foot-Ankle Kinematics and Running Kinetics in Runners: Secondary Outcomes From a Randomized Controlled Trial
    (2022) MATIAS, Alessandra B.; WATARI, Ricky; TADDEI, Ulisses T.; CARAVAGGI, Paolo; INOUE, Rafael S.; THIBES, Raissa B.; SUDA, Eneida Y.; VIEIRA, Marcus F.; SACCO, Isabel C. N.
    This study investigated the effectiveness of an 8-week foot-core exercise training program on foot-ankle kinematics during running and also on running kinetics (impact loads), with particular interest in biomechanical outcomes considered risk factors for running-related injuries in recreational runners. A single-blind, randomized, controlled trial was conducted with 87 recreational runners randomly allocated to either the control (CG) or intervention (IG) group and assessed at baseline and after 8 weeks. The IG underwent foot-core training 3 times/week, while the CG followed a placebo lower-limb stretching protocol. The participants ran on a force-instrumented treadmill at a self-selected speed while foot-segment motion was captured simultaneously with kinetic measurements. After the intervention, there were statistically significant changed in foot biomechanics, such as: IG participants strike the ground with a more inverted calcaneus and a less dorsiflexed midfoot than those in the CG; at midstance, ran with a less plantarflexed and more adducted forefoot and a more abducted hallux; and at push-off, ran with a less dorsiflexed midfoot and a less adducted and more dorsiflexed hallux. The IG runners also had significantly decreased medial longitudinal arch excursion (p = 0.024) and increased rearfoot inversion (p = 0.037). The 8-week foot-core exercise program had no effect on impact (p = 0.129) and breaking forces (p = 0.934) or on vertical loading rate (p = 0.537), but it was positively effective in changing foot-ankle kinematic patterns.""

    Experimental knee-related pain enhances attentional interference on postural control
    (2019) SUDA, Eneida Yuri; HIRATA, Rogerio Pessoto; PALSSON, Thorvaldur; VUILLERME, Nicolas; SACCO, Isabel C. N.; GRAVEN-NIELSEN, Thomas
    Purpose To quantify how postural stability is modified during experimental pain while performing different cognitively demanding tasks. Methods Sixteen healthy young adults participated in the experiment. Pain was induced by intramuscular injection of hypertonic saline solution (1 mL, 6%) in both vastus medialis and vastus lateralis muscles (0.9% isotonic saline was used as control). The participants stood barefoot in tandem position for 1 min on a force plate. Center of pressure (CoP) was recorded before and immediately after injections, while performing two cognitive tasks: (i) counting forwards by adding one; (ii) counting backwards by subtracting three. CoP variables-total area of displacement, velocity in anterior-posterior (AP-velocity) and medial-lateral (ML-velocity) directions, and CoP sample entropy in anterior-posterior and medial-lateral directions were displayed as the difference between the values obtained after and before each injection and compared between tasks and injections. Results CoP total area ( - 84.5 +/- 145.5 vs. 28.9 +/- 78.5 cm(2)) and ML-velocity ( - 1.71 +/- 2.61 vs. 0.98 +/- 1.93 cm/s) decreased after the painful injection vs. Control injection while counting forward (P < 0.05). CoP total area (12.8 +/- 53.9 vs. - 84.5 +/- 145.5 cm(2)), ML-velocity ( - 0.34 +/- 1.92 vs. - 1.71 +/- 2.61 cm/s) and AP-velocity (1.07 +/- 2.35 vs. - 0.39 +/- 1.82 cm/s) increased while counting backwards vs. forwards after the painful injection (P < 0.05). Conclusion Pain interfered with postural stability according to the type of cognitive task performed, suggesting that pain may occupy cognitive resources, potentially resulting in poorer balance performance.

    Foot-ankle functional outcomes of using the Diabetic Foot Guidance System (SOPeD) for people with diabetic neuropathy: a feasibility study for the single-blind randomized controlled FOotCAre (FOCA) trial I
    (2021) CRUVINEL JUNIOR, Ronaldo H.; FERREIRA, Jane S. S. P.; I, Raquel Beteli; SILVA, Erica Q.; VERISSIMO, Jady L.; MONTEIRO, Renan L.; SUDA, Eneida Y.; SACCO, Isabel C. N.
    Background: Diabetic neuropathy dramatically affects musculoskeletal structure and function of the lower limbs by impairing their muscle strength and mobility. Specific muscle strengthening through physiotherapy strategies appears to be promising; however, adherence to physiotherapy treatment is low in people with chronic diseases. Thus, an internet-based foot-ankle exercise program was created as a potential telerehabilitation alternative for people with diabetes to improve their self-monitoring and self-care management. This study assessed the feasibility, safety, acceptability, and changes in foot health and neuropathy symptoms in people with diabetes after 12 weeks of the intervention program with the Sistema de Orientacao ao Pe diabetico - Diabetic Foot Guidance System (SOPeD). Methods: Fourteen individuals were recruited and randomized to either the usual care (control group) or usual care plus an internet-based foot-ankle exercise program through SOPeD (intervention group) three times per week for 12 weeks. For feasibility, we assessed contact and recruitment rates per week; program adherence, determined as completing over 70% of the 36 sessions; and participant satisfaction and safety assessed through a questionnaire and scored on a 5-point Likert scale. We assessed changes in neuropathy symptoms and foot health and functionality from baseline to 12 weeks estimating differences or median of differences and 95% confidence intervals in the intervention group. Results: In 24 weeks, of the 822 patients in the database, 192 were contacted, 65 were assessed for eligibility, and 20 were considered eligible. The recruitment rate was 0.83 participants per week. Fourteen out of the 20 eligible participants agreed to participate, resulting in recruitment success of 70%. Adherence to the program was 66.7%, and there was no dropout. Participants' median level of satisfaction was 5.0 (IQR: 4.5-5.0) and perceived safety was 5.0 (IQR: 5.0-5.0). Conclusion: The internet-based foot-ankle exercise program using SOPeD is feasible, satisfactory, and safe. Although this study had moderate adherence and a zero-dropout rate, recruitment needs to be improved in the larger trial.
