conferenceObject CHRONIC EFFECTS OF A FLEXIBLE AND MINIMALIST FOOTWEAR ON CLINICAL, FUNCTIONAL AND GAIT BIOMECHANICAL ASPECTS IN THE KNEE OSTEOARTHRITIS: A SINGLE-BLIND RANDOMIZED CLINICAL TRIAL(2012) TROMBINI-SOUZA, F.; MATIAS, A.; YOKOTA, M.; SCHAINBERG, C.; FULLER, R.; SACCO, I. C.Purpose: Recent studies have shown that the acute use of shoes that mimic barefoot gait decrease substantially knee loads while walking in elderly with knee osteoarthritis (OA). Probably due to methodological difficulties to implement this type of conservative treatment during extended period, the effectiveness of minimalist footwear has not been evaluated yet in elderly patients with knee OA. The purpose is to describe a randomized clinical trial protocol for evaluating the therapeutic effect of a minimalist (flexible, non-heeled) and inexpensive footwear on clinical, functional, and biomechanical gait in elderly women with knee OA. Methods: Fifty six elderly women with knee OA grade 2 or 3 (Kellgren and Lawrence) will be randomized in blocks and allocated in the intervention group that will use a flexible non-heeled shoes- Moleca® forat least 6 hours daily or in the control group, which could not use these shoes or be under physical therapy or acupuncture treatment throughout these sis months. The use of Paracetamol 500 mg every six hour was allowed for both groups in case of pain. Moleca® (Calçados Beira Rio S.A., Novo Hamburgo, RS, Brazil) is a women's double canvas flexiblefl at walking shoe without heels, with a 5-mm anti-slip rubber sole and a 3-mm internal wedge of ethylene vinyl acetate. The mean weight is 172±19.6 g, ranging from 142 to 193 g depending on the size. Both groups will be followed during 6 months. They will be assessed at baseline condition, after 3 months (intervention group) and after 6 months of baseline condition(end of intervention, both groups). All the assessments will be performed by a physiotherapist that is blind to which group thepatient was allocated. The main outcome assessmentis the pain WOMAC score and the secondary outcomes are other WOMAC scores pain assessment (visual analogue scale - VAS), Lequesne index, Six-Minute Walk Test, and biomechanical gait analysis by means of 6 infrared cameras and a multi-component force plate to determine the knee adduction moment during gait. At baseline, all patients receive a diary to record the hours of daily use of footwear intervention. Every two weeks, the same physiotherapist carries phone calls to all patients in order to verify adherence to treatment and the correct filling this diary. Theinter group andinter-moments will be performed by repeated measures analysis of variance (α=0.05). This Trial was approved by the local Ethics Committee and was registered in ClinicalTrials.gov Identifier: NCT01342458. Results: Six hundred thirty-four elderly women have been contacted so far and 20 have already been allocated in the intervention group (9) and in the control (11). Five patients from intervention group have already completed all 3 assessments and finished the protocol. The preliminary results have shown that the elderly women of the intervention group have used the Moleca® shoe for an average monthly of 7 hours and 24 minutes (±3:47), corresponding to approximately 50% of the home-work hours of the day. Conclusion: This is the first randomized clinical trial protocol to assess the chronic effect of a minimalist footwear on the clinical, functional and gait biomechanics of elderly women with knee osteoarthritis. We expect that the use of Moleca® shoes for 6 months provides pain relief, reduction of the knee adduction moment while walking and improves joint function in elderly women with knee OA, and therefore can be considered as another inexpensive option for conservative OA treatment.

C.- Long-term use of minimal footwear on pain, self-reported function, analgesic intake, and joint loading in elderly women with knee osteoarthritis: A randomized controlled trial(2015) TROMBINI-SOUZA, Francis; MATIAS, Alessandra B.; YOKOTA, Mariane; BUTUGAN, Marco K.; GOLDENSTEIN-SCHAINBERG, Claudia; FULLER, Ricardo; SACCO, Isabel C. N.Background: Efforts have been made to retard the progressive debilitating pain and joint dysfunction in patients with knee osteoarthritis. We aimed to evaluate the therapeutic effect of a low-cost minimalist footwear on pain, function, clinical and gait-biomechanical aspects of elderly women with knee osteoarthritis. Methods: Throughout a randomized, parallel and controlled clinical trial, fifty-six patients with medial knee osteoarthritis were randomly allocated to an intervention (n = 28) or control group (n = 28), and assessed at baseline and after three and six months. The intervention involved wearing Moleca footwear for at least 6 h/day, 7 days/week, over 6 months. The pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index was the primary outcome. The secondary outcomes were the other subscales, Lequesne score, distance walked in 6 min, knee oedema and effusion, knee adduction moment and paracetamol intake. Intention-to-treat analysis was performed using two-way casewise ANOVA (< .05) and Cohen's d coefficient. Findings: Intervention group showed improvement in pain (effect size: 1.41, p < .001), function (effect size: 1.22, p = .001), stiffness (effect size: 0.76, p = .001), Lequesne score (effect size: 1.07, p < .001), and reduction by 21.8% in the knee adduction moment impulse (p = .017) during gait wearing Moleca (R). The analgesic intake was lower in the intervention group. Interpretation: The long-term use of Moleca (R) footwear relieves pain, improves self-reported function, reduces the knee loading while wearing Moleca (R), refrains the increase of analgesic intalce in elderly women with knee ostearthritis and can be considered as a conservative mechanical treatment option.

C.- Axial Gout Is Frequently Associated With the Presence of Current Tophi, Although Not With Spinal Symptoms(2014) MELLO, Filipe Martins de; HELITO, Paulo Victor Partezani; BORDALO-RODRIGUES, Marcelo; FULLER, Ricardo; HALPERN, Ari Stiel RaduStudy Design. Prospective cross-sectional study. Objective. To analyze the association of tomographically identified axial gouty lesions with clinical and laboratory characteristics. Summary of Background Data. Axial gout might be more common than previously thought. The true relationship of these lesions to symptoms or other gout-associated features is poorly understood. Methods. Forty-two patients with gout underwent thoracic and lumbar spine computed tomographic (CT) scans. CT scans were read by an experienced radiologist blinded to the features of the patients. Axial gout was defined as the presence of bony erosions, facet joints, or disc calcification and tophi in the axial skeleton. Epidemiological and clinical data were collected from medical records. At study entry, patients were evaluated for axial symptoms (back pain or neurological complaints) and subcutaneous tophi. The Fisher exact test and the Student t test were performed for statistical analyses of data. Results.Twelve (29%) of the 42 patients had CT evidence of axial gout. Axial tophi were identified in 5 patients (12%), interapophyseal joints erosions or calcifications in 7 patients (17%), and discal abnormalities in 9 patients (21%). Lumbar spine involvement was a universal finding. Five patients (42%) had thoracic spine involvement and 2 patients (18%) had sacroiliac lesions. No association was found between symptoms and axial gout (P = 0.62). Duration of gout, mechanism of disease (overproduction vs. underexcretion), and metabolic comorbidities were not related to axial involvement. A higher prevalence of axial gout was found between patients with current peripheral tophi (67% vs. 30%; P = 0.03); however, no association was found in patients with a past history of tophi (P = 0.72). Conclusion. Our study demonstrated a high prevalence of axial gout not associated with spine symptoms. This finding introduces a differential diagnosis in axial lesions in patients with gout. In addition, the unique association with a current but not previous history of peripheral tophi suggests that gout treatment might be effective in preventing or solving gout axial lesions.
- Efficacy of platelet-rich plasma and plasma for symptomatic treatment of knee osteoarthritis: a double-blinded placebo-controlled randomized clinical trial(2021) DORIO, Murillo; PEREIRA, Rosa Maria Rodrigues; LUZ, Alexandre Galeno Branco; DEVEZA, Leticia Alle; OLIVEIRA, Ricardo Manoel de; FULLER, RicardoBackground: Platelet-rich plasma (PRP) has a still conflicting efficacy for knee osteoarthritis (KOA) and might be a minimally invasive and safe treatment alternative. The potential benefit of only plasma (non-enriched) has never been investigated. Our aim was to evaluate the efficacy of intra-articular platelet-rich plasma (PRP) and plasma to improve pain and function in participants with KOA over 24 weeks. Methods: Randomized, double-blind, placebo-controlled trial with 3 groups (n = 62): PRP (n = 20), plasma (n = 21) and saline (n = 21). Two ultrasound-guided knee injections were performed with a 2-week interval. The primary outcome was visual analog scale 0-10 cm (VAS) for overall pain at week 24, with intermediate assessments at weeks 6 and 12. Main secondary outcomes were: KOOS, OMERACT-OARSI criteria and TUGT. Results: At baseline, 92% of participants were female, with a mean age of 65 years, mean BMI of 28.0 Kg/m(2) and mean VAS pain of 6.2 cm. Change in pain from baseline at week 24 were -2.9 (SD 2.5), -2.4 (SD 2.5) and -3.5 cm (SD 3.3) for PRP, plasma and saline, respectively (p intergroup = 0.499). There were no differences between the three groups at weeks 6 and 12. Similarly, there were no differences between groups regarding secondary outcomes. The PRP group showed higher frequency of adverse events (65% versus 24% and 33% for plasma and saline, respectively, p = 0.02), mostly mild transitory increase in pain. Conclusions: PRP and plasma were not superior to placebo for pain and function improvement in KOA over 24 weeks. The PRP group had a higher frequency of mild transitory increase in pain.
- Effectiveness of a long-term use of a minimalist footwear versus habitual shoe on pain, function and mechanical loads in knee osteoarthritis: a randomized controlled trial(2012) TROMBINI-SOUZA, Francis; FULLER, Ricardo; MATIAS, Alessandra; YOKOTA, Mariane; BUTUGAN, Marco; GOLDENSTEIN-SCHAINBERG, Claudia; SACCO, Isabel C. N.Background: Recent studies have shown an important reduction of joint overload during locomotion in elderly women with knee osteoarthritis (OA) after short- term use of minimalist shoes. Our aim is to investigate the chronic effect of inexpensive and minimalist footwear on the clinical and functional aspects of OA and gait biomechanics of elderly women with knee OA. Methods/Design: Fifty-six elderly women with knee OA grade 2 or 3 (Kellgren and Lawrence) are randomized into blocks and allocated to either the intervention group, which will use flexible, non-heeled shoes-Moleca (R)-for six months for at least six hours daily, or the control group, which could not use these shoes. Neither group is undergoing physical therapy treatment throughout the intervention period. Moleca (R) is a women's double canvas, flexible, flat walking shoe without heels, with a 5-mm anti-slip rubber sole and a 3-mm internal wedge of ethylene vinyl acetate. Both groups will be followed for six months and will be assessed at baseline condition, after three months, and after six months (end of intervention). All the assessments will be performed by a physiotherapist that is blind to the group allocation. The primary outcome is the pain Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score. The secondary outcomes are global WOMAC score; joint stiffness and disability WOMAC scores; knee pain with a visual analogue scale; walking distance in the six-minute walk test; Lequesne score; amount and frequency (number of days) of paracetamol (500 mg) intake over six months; knee adduction moment during gait; global medical assessment score; and global patient auto-assessment score. At baseline, all patients receive a diary to record the hours of daily use of the footwear intervention; every two weeks, the same physiotherapist makes phone calls to all patients in order to verify adherence to treatment. The statistical analysis will be based on intention to treat analysis, as well as general linear models of analysis of variance for repeated measure to detect treatment-time interactions (alpha = 5%). Discussion: This is the first randomized, clinical trial protocol to assess the chronic effect of minimalist footwear on the clinical and functional aspects and gait biomechanics of elderly women with knee osteoarthritis. We expect that the use of Moleca (R) shoes for six months will provide pain relief, reduction of the knee adduction moment when walking, and improve joint function in elderly women with knee OA, and that the treatment, thus, can be considered another inexpensive and easy-to-use option for conservative OA treatment.
- A rare giant geode of humeral head in an uncontrolled rheumatoid arthritis: a case report(2023) PIROLA, Fernanda Junqueira Cesar; DORIO, Murillo; FULLER, Ricardo; COBRA, Jayme Fogagnolo; SALES, Lucas Peixoto; FIGUEIREDO, Camille PintoIntroductionRheumatoid Arthritis (RA) is a chronic inflammatory disease depicted by peripheral bone erosive damage leading to joint destruction, deformity and functional impairment. Shoulder involvement is less frequent than hands, wrists and feet, and relevant joint damage may be underdiagnosed if a lower threshold for careful analysis of this joint is not settled, especially in uncontrolled disease.Case ReportA 70-year-old male with a difficult-to-manage RA since 2010, presenting severe shoulder arthritis with MRI showing a striking giant geode in the left humeral head.ConclusionAn impressive MRI image showing a giant geode in poorly controlled RA should alert rheumatologists to raise suspicion of shoulder involvement for early investigation and treatment.
