article 2 Citação(ões) na Scopus The Association Between Rearfoot Motion While Barefoot and Shod in Different Types of Running Shoes in Recreational Runners(2020) SILVA, Erica Q.; MIANA, Andreia N.; FERREIRA, Jane S. S. P.; KIYOMOTO, Henry D.; DINATO, Mauro C. M. E.; SACCO, Isabel C. N.The rearfoot angle (RFA) is a biomechanical variable widely used to determine the rearfoot motion (RM). Shoe manufacturers began to develop running shoes with RM control that would supposedly alter foot-ground interaction mechanics and neutralize excessive pronation or supination; moreover, some studies have not shown differences in rearfoot motion in shod condition compared to barefoot. This study intended to answer three questions: Do the shoes runners wear correspond to their respective barefoot RM? Does the eversion angle change during shod running, regardless the shoes worn? Can footwear designed for a specific RM (supination, pronation, neutral) correct or neutralize the eversion angle of runners? One hundred and eleven runners (38.6 +/- 9.7years; 74.9 +/- 12.0kg; 1.74 +/- 0.08 m), who ran an average of 32 +/- 17km/week, were included in this cross-sectional study. They had their RFA measured by a motion capture system when running barefoot and wearing their habitual running shoes (shod condition). Chi-squared test was used to assess associations between barefoot and shod condition and RFA was compared between conditions using Wilcoxon tests (p = 0.05). There was no association between the type of running shoe and barefoot RM (p > 0.05). There was an association between RFA when barefoot and when shod (p < 0.05). Among all participants classified as neutral, 61% continued to exhibit a normal/neutral RFA when wearing their habitual shoes. Among the overpronators, 100% showed a change in the RM to either normal or supinator. Among the participants classified as supinators, 62% exhibited normal pronation when shod even without using the appropriate footwear, claimed by the manufacturer. Only 44.1% of the sample chose the correct running shoe for their barefoot RM. The majority of runners did not choose their shoes designed for their natural type of RM. The rearfoot eversion angle changed an average 4 degrees when running shod and the RM barefoot altered quite a lot when using a running shoe. The running shoes did not correct the pronation detected barefoot, as claimed by the manufacturers.- 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.
- Feasibility and Preliminary Efficacy of a Foot-Ankle Exercise Program Aiming to Improve Foot-Ankle Functionality and Gait Biomechanics in People with Diabetic Neuropathy: A Randomized Controlled Trial(2020) MONTEIRO, Renan L.; FERREIRA, Jane S. S. P.; SILVA, Erica Q.; DONINI, Asha; CRUVINEL-JUNIOR, Ronaldo H.; VERISSIMO, Jady L.; BUS, Sicco A.; SACCO, Isabel C. N.Foot-ankle strengthening and mobility exercises are part of international guideline recommendations for people at risk of diabetic foot disease. We examined the feasibility and preliminary efficacy of a 12-week foot-ankle exercise program on clinical, functional and biomechanical outcomes in people with diabetic neuropathy (DPN). We randomly allocated 30 people with DPN to usual care (control) or usual care plus a supervised exercise program (intervention). For feasibility, we assessed recruitment rate and participant adherence and satisfaction. For program efficacy, we assessed baseline to 12-week changes in daily physical activity level, gait speed, tactile sensitivity, ankle range of motion, DPN symptoms, quality of life, foot health and functionality, foot strength and plantar pressure during gait, using paired t-tests (p< 0.05). In 52 weeks, we recruited 45 eligible participants (0.90/week). Program adherence was 80% and participants' satisfaction had a mean (SD) of 4.57 (0.70) out of 5. The intervention group significantly improved on toes strength, contact time during gait and DPN symptoms, and peak forefoot pressures increased over time; controls showed significantly increased heel peak pressures and force. The exercise program was feasible, based on a moderate recruitment rate and an adherent and satisfied population, and the intervention showed several positive preliminary effects over time compared to usual care.
- Effect of an educational booklet for prevention and treatment of foot musculoskeletal dysfunctions in people with diabetic neuropathy: the FOotCAre (FOCA) trial II, a study protocol of a randomized controlled trial(2020) SILVA, E. Q.; SUDA, E. Y.; SANTOS, D. P.; VERISSIMO, J. L.; FERREIRA, J. S. S. P.; CRUVINEL JUNIOR, R. H.; MONTEIRO, R. L.; SARTOR, C. D.; SACCO, I. C. N.Background This study is a part of a series of two clinical trials. We consider diabetic polyneuropathy (DPN), a common chronic and progressive complication of diabetes mellitus that has several impacts on individuals' foot health and quality of life. Based on the current trends of self-monitoring and self-care, providing a tool with foot-related exercises and educational care may help patients to avoid or reduce the musculoskeletal complications resulting from DPN, improving autonomous performance in daily living tasks. The aim of this trial is to evaluate the effects of an educational booklet for foot care and foot muscle strengthening on DPN symptoms and severity, clinical outcomes, and gait biomechanics in patients with DPN. Methods/design The FOotCAre (FOCA) trial II study has been designed as a single-blind, two-parallel-arm randomized controlled trial. It will include 48 patients with DPN who will be randomly allocated to a control (recommended foot care by international consensus with no foot exercises) group or an intervention (foot-related exercises using an educational booklet three times/week at home for 8 weeks) group. Participants from both groups will be assessed at baseline, after 8 weeks, and at 16 weeks for follow-up. The primary outcomes are the DPN symptoms and severity, and the secondary outcomes are foot-ankle kinematics, gait kinetics, plantar pressure distribution during gait, tactile and vibratory sensitivities, foot strength, functional balance, and foot health and functionality. Discussion The booklet is a management tool that allows users to be autonomous in their treatment by choosing how and where to perform the exercises. This allows the patients to perform the exercises regularly as a continuous habit for foot care and health, which is an important element in the management of the diabetic foot. As the booklet focuses on specific foot-ankle exercises, we expect that it will improve the clinical aspects of DPN and produce beneficial biomechanical changes during gait, becoming a powerful self-management tool that can be easily implemented to improve the performance of daily living tasks.
