- The effects of plantar fasciitis and pain on plantar pressure distribution of recreational runners(2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; TESSUTTI, Vitor D.; LIMA, Fernanda R.; JOAO, Silvia M. A.; SACCO, Isabel C. N.Background: Plantar fasciitis is the third most frequent injury in runners. Despite its high prevalence, its pathogenesis remains inconclusive. The literature reports overload as the basic mechanism for its development. However, the way that these plantar loads are distributed on the foot surface of runners with plantar fasciitis and the effects of pain on this mechanical factor has not yet been investigated. Therefore, the aim of this study was to evaluate and compare the plantar pressure distributions during running in runners with symptom or history of plantar fasciitis and runners without the disease. Methods: Forty-five recreational runners with plantar fasciitis (30 symptomatic and 15 with previous history of the disease) and 60 runners without plantar fasciitis (control group) were evaluated. Pain was assessed by a visual analogue scale. All runners were evaluated by means of the Pedar system insoles during running forty meters at a speed of 12(5%) km/h, using standard sport footwear. Two-way ANOVAS were employed to investigate the main and interaction effects between groups and plantar areas. Findings: No interaction effects were found for any of the investigated variables: peak pressure (P=0.61), contact area (P=0.38), contact time (P=0.91), and the pressure-time integral (P=0.50). Interpretation: These findings indicated that the patterns of plantar pressure distribution were not affected in recreational runners with plantar fasciitis when compared to control runners. Pain also did not interfere with the dynamic patterns of the plantar pressure distributions.
- Postural control during single leg stance in individuals with clinical indication for combined reconstruction of the anterior cruciate and the anterolateral ligaments of the knee: a cross-sectional study(2022) NOVAES, Marilia; CARVALHO, Adriana; SAUER, Juliana F.; BRECH, Guilherme C.; HELITO, Camilo P.; JOAO, Silvia M. A.Background Several studies have shown persistent postural control deficits and rotatory instability in patients after isolated Anterior Cruciate Ligament (ACL) reconstruction. There is evidence to support that the Anterolateral Ligament (ALL) plays an important role in the remaining anterolateral rotatory laxity of the knee. There are no further evidences in order to understand how patients with a combined ACL + ALL reconstruction surgery indication behave regarding postural control. The aim of this cross-sectional study was to assess if patients with a clinical indication for the combined ACL + ALL surgery showed a deficient postural control in single leg stance compared to subjects with a regular ACL reconstruction indication and to a control group. Methods An assessment of static postural control on single leg stance was performed on a force plate, with eyes open and closed, and the center of pressure (COP) displacement variables were analyzed: maximum and mean amplitude in anteroposterior (AP) and in mediolateral (ML) direction; mean velocity of displacement and area of displacement. Eighty-nine male individuals participated and were divided into 3 groups: ACL Group, ACL + ALL Group and Control Group. Results The ACL+ ALL Group showed significantly greater COP displacement in most variables in the injured leg for the eyes closed test, compared to the ACL Group, as detailed: Total ML displacement (9.8 +/- 6.77 vs. 13.98 +/- 6.64, p < 0.001); Mean ML displacement (2.58 +/- 2.02 vs. 3.72 +/- 1.99, p < 0.001); Total AP displacement (9.5 +/- 3.97 vs. 11.7 +/- 3.66, p = 0.001); Mean AP displacement (1.77 +/- 0.87 vs. 2.27 +/- 0.86, p = 0.001); Area of displacement (111.44 +/- 127.3 vs. 183.69 +/- 131.48, p < 0.001). Conclusion Subjects with a clinical indication for ACL + ALL combined reconstruction surgery showed increased COP displacement compared to patients with indication for an ACL isolated reconstruction surgery.
bookPart Dores lombares(2013) JOãO, Sílvia Maria Amado; MARQUES, Amélia Pasqual; FERREIRA, Elizabeth Alves Gonçalves- Effectiveness of mechanical treatment with customized insole and minimalist flexible footwear for women with calcaneal spur: randomized controlled trial(2022) RIBEIRO, Ana Paula; SOUZA, Brenda Luciano de; JOAO, Silvia Maria AmadoBackround: Calcaneal spurs are described as bony outgrowths arising on medial calcaneal, where inappropriate footwear can promote disease progression. Objective: Investigate the effectiveness of mechanical treatment with customized insole and minimalist flexible footwear during gait training program in women with calcaneal spur. Methods: Design: A single-blinded, randomized and controlled trial. Setting: Biomechanics laboratory. Participants: Forty-three women, 29 with calcaneal spur and 14 control. Intervention: Gait training program with use of the minimalist flexible footwear (MFG n = 15, age: 48.9 +/- 9.4, height: 1.61 +/- 0.1, BMI: 32.1 +/- 7.0) and customized insole on footwear (COIG n = 14, age: 50.3 +/- 5.8, height: 1.62 +/- 0.1, BMI: 32.2 +/- 4.3) and control (CG n = 14, age: 47.8 +/- 8.6, height: 1.63 +/- 0.1, BMI: 27.5 +/- 4.5), followed of the evaluations: baseline (T0) and after three (T3) and six (T6) months. Duration of the intervention was of the six months consecutive for at least 42 h per week (six hours a day, seven days a week). Outcome primary were calcaneus pain (visual analogue scale), Foot Function Index (FFI), Foot Health Status Questionnaire (FHSQ-Br) and 6-min walk test (6MWT). Secondary was plantar pressure distribution by a pressure platform system during gait and static index foot posture (FPI). Statistical analysis: analysis of variance for repeated measure and between groups were used to detect treatment-time interactions (alpha = 5%). Effect size with D Cohen's also was used between T0 and after six (T6) months of intervention. Results: The MFG and COIG were effective at reducing pain after six months (MFG: 2.5-4.5 CI, p = 0.001; COIG: 1.5-3.5 CI, p = 0.011). The FFI and FHSQ-Br showed improvements with MFG and COIG after T6 (MFG: 13.7-15.4 CI, p = 0.010; COIG: 11.3-15.0 CI, p = 0.001). The 6MWT increased with MFG (589.3-622.7 CI) and COIG (401.3-644.7 CI) and foot pronation was decreased after T3 and T6 MFG (FPI Right: 4.2-5.4 CI; Left: 3.6-5.4 CI) COIG (FPI Right: 3.4-6.8 CI; Left: 3.3-5.7 CI). The contact area reduced on forefoot and rearfoot with MFG and GOIG and midfoot and rearfoot with MFG. Maximum force was reduced on foot with MFG after T3 and T6. The peak pressure was reduced on the forefoot with MFG and COIG and on midfoot and rearfoot with MFG. Conclusions: The mechanical treatment with customized insole and minimalist flexible footwear during gait training program during six months in women with calcaneal spur reduced the calcaneus pain, increased function and health feet and reduced plantar load on the rearfoot, midfoot and forefoot. However, the footwear alone was more effective than when combined customized insole, given the greater efficacy on clinical and biomechanical aspects.
- Treatment time of ultrasound therapy interferes with the organization of collagen fibers in rat tendons(2013) FARCIC, Thiago S.; BALDAN, Cristiano S.; CATTAPAN, Carla G.; PARIZOTTO, Nivaldo A.; JOAO, Silvia M. A.; CASAROTTO, Raquel A.BACKGROUND: The application time of therapeutic ultrasound is an infrequently studied dosimetric variable that affects tissue repair. OBJECTIVES: The aim of this study was to evaluate the effects of different treatment times of therapeutic ultrasound (US) on the organization of collagen fibers in the tendons of rats. METHOD: Forty Wistar rats were selected (300±45 g), and the rats were divided into five groups (n=8 for each group): Control, without tenotomy or any treatment; tenotomy group, with tenotomy and without treatment; US groups (US1, US2, and US3), subjected to tenotomy and treated with US for one, two, or three minutes per area of the transducer, respectively. The animals were sacrificed on the 12th post-operative day, and the tendons were surgically removed for analyses of the collagen fiber organization by means of birefringence analysis. RESULTS: The collagen fibers exhibited better aggregation and organization in the US3 group compared with the tenotomy group (p<0.05). CONCLUSIONS: The findings suggest that US applied for three minutes per treated area improves the organization of collagen fibers during rat tendon repair.
- Muscle function, Lysholm score and hop performance in individuals with clinical indications for the combined reconstruction of the anterior cruciate and the anterolateral ligaments of the knee: A cross-sectional study(2023) CARVALHO, Adriana; NOVAES, Marilia; SAUER, Juliana; DEMANGE, Marco Kawamura; HELITO, Camilo Partezani; JOAO, Silvia Maria AmadoObjective: To evaluate hip and knee muscular function, knee patient-reported outcome measures and hop performance in patients with a clinical indication for combined ACL+ALL reconstruction surgery compared to patients with an isolated ACL reconstruction surgery indication (preoperative phase) and to a control group. Design: Cross-sectional study. Methods: The sample was composed of male individuals, aged between 18 and 59 years, divided into three groups (ACL, ACL+ALL and Control). Isokinetic dynamometry was performed for the flexor and extensor knee muscles and for the hip abductors and adductors. SLHT, COHT and the Lysholm score were performed. Pain, swelling, and thigh trophism were also measured. Results: The study participants were 89 male individuals: 63 in the injury group and 26 in the control group. After applying the criteria for an ALL reconstruction indication, 33 patients were assigned to the ACL Group and 30 patients to the ACL+ALL Group. Regarding knee and hip muscle function, both groups presented worse results when compared to the control group, however, did not show significant differences compared to each other. Regarding the functional variables, the ACL+ALL group showed a significantly shorter distance achieved in the Crossover Hop Test than the other groups, as well as more pain during the tests. Conclusion: Knee and hip muscular functions are impaired after an ACL injury and do not seem to be influenced or worsened in individuals with greater rotational instability with clinical indications for combined reconstruction of the anterior cruciate and the anterolateral ligaments of the knee.
article 27 Citação(ões) na Scopus Changes in the Plantar Pressure Distribution During Gait Throughout Gestation(2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; SACCO, Isabel de Camargo Neves; RUANO, Rodrigo; ZUGAIB, Marcelo; JOAO, Silvia Maria AmadoBackground: The intention of this investigation was to longitudinally describe and compare the plantar pressure distribution in orthostatic posture and gait throughout pregnancy. Methods: A prospective longitudinal observational study was conducted with six pregnant women (mean +/- SD age, 32 +/- 3 years) with a mean +/- SD weight gain of 10.0 +/- 1.4 kg. Peak pressure, contact time, contact area, and maximum force in five plantar areas were evaluated using capacitive insoles during gait and orthostatic posture. For 1 year, the plantar pressures of pregnant women were evaluated the last month of each trimester. Comparisons among plantar areas and trimesters were made by analysis of variance. Results: For orthostatic posture, no differences in contact time, contact area, peak pressure, and maximum force throughout the trimesters were found. During gait, peak pressure and maximum force of the medial rearfoot were reduced from the first to third and second to third trimesters. Maximum force increased at the medial forefoot from the first to second trimester. Contact area increased at the lateral rearfoot from the second to third trimester and at the midfoot from the first to third trimester. Contact time increased at the midfoot and medial and lateral forefoot from the first to third trimester. Conclusions: Pregnant women do not alter plantar pressure during orthostatic posture, but, during gait, the plantar loads were redistributed from the rearfoot (decrease) to the midfoot and forefoot (increase) throughout pregnancy. These adjustments help maintain the dynamic stability of the pregnant woman during locomotion. (J Am Podiatr Med Assoc 101(5): 415-423, 2011)- Posture Alignment of Adolescent Idiopathic Scoliosis: Photogrammetry in Scoliosis School Screening(2017) PENHA, Patricia Jundi; PENHA, Narima Livia Jundi; KELLY, Barbarah; CARVALHO, Goncalves De; ANDRADE, Rodrigo Mantelatto; SCHMITT, Ana Carolina Basso; JOAO, Silvia Maria AmadoObjective: The objective of this study was to describe the posture patterns of adolescents diagnosed with adolescent idiopathic scoliosis (AIS) in a scoliosis school screening (SSS). Methods: Two-dimensional photogrammetry was used to assess the posture of 37 adolescents diagnosed with scoliosis (scoliosis group, SG) (Cobb angle >= 10 degrees) and 76 adolescents with a false positive diagnosis (false positive group, FPG) (Cobb angle <10 degrees, angle of trunk rotation >= 7 degrees). In total, 2562 10-to 14-year-old adolescents were enrolled in the SSS, which was performed in public schools in the cities of Amparo, Pedreira, and Mogi Mirimin the state of Sao Paulo, Brazil. Their posture was analyzed using Postural Analysis Software. Continuous variables were tested using Student t test, and categorical variableswere tested using a chi(2) test. The SG, FPG, simple curve group, and double curve groupwere all compared. Bivariate analysis was used to identify associations between postural deviations and scoliosis. The adopted significance level was alpha = .05. Results: The SG (2.7 +/- 1.9 degrees) had greater shoulder obliquity than the FPG (1.9 +/- 1.4 degrees) (P = .010), and this deviation was associated with scoliosis (odds ratio [95% CI] P = 1.4 [1.1-1.8] 0.011). The SG had asymmetry between the right-and left-side lower limb frontal angle, shoulder sagittal alignment, and knee angle. The double curve group (3 +/- 1.7 degrees) presented a greater value of the vertical alignment of the torso than the simple curve group did (1.9 +/- 1 degrees; P = .032). Conclusions: Adolescents diagnosed with AIS in an SSS had greater shoulder obliquity and asymmetry between the right and left sides. Shoulder obliquity was the only postural deviation associated with AIS.
conferenceObject Correlation between vitamin D, parathormone, creatinine and functional capacity of patients with end stage renal disease(2013) FRACINI, America; ABENSUR, Hugo; HASUE, Renata; JOAO, Silvia; FU, Carolina- Transcranial Direct Current Stimulation Combined With Therapeutic Exercise in Chronic Low Back Pain: Protocol of a Randomized Controlled Trial(2020) CAVALCANTE, Polyanna Gomes Lacerda; BAPTISTA, Abrahao Fontes; CARDOSO, Vinicius Saura; FILGUEIRAS, Marcelo de Carvalho; HASUE, Renata Hydee; JOAO, Silvia Maria Amado; HAZIME, Fuad AhmadObjective. Although some studies have shown the clinical benefits of therapeutic exercise in chronic nonspecific low back pain, the effect sizes are generally small to moderate and recurrence rates are high. Transcranial direct current stimulation (tDCS) has been used to modulate pain-processing systems and motor outputs and has the potential to optimize the clinical benefits of therapeutic exercise. However, evidence for this combination is still lacking. The purpose of this protocol for a randomized clinical trial is to investigate whether the combination of tDCS and therapeutic exercise is more effective in relieving pain than therapeutic exercise alone. Methods. This 2-arm, randomized controlled clinical trial will take place at the Federal University of Piaui, Brazil. Sixty patients will be randomized into 2 groups to receive tDCS (real/sham) + exercise therapies for 12 sessions over a period of 4 weeks. Pain intensity, sensory and affective aspects of pain, physical functioning, kinesiophobia, and global perceived effect will be recorded before treatment and at 4 weeks, 3 months, and 6 months after randomization. Data will be collected by an examiner unaware of (blind to) the treatment allocation. Impact. This trial can potentially provide important information and assist in clinical decision-making on the combined use of tDCS to optimize the clinical benefits of therapeutic exercise in patients with chronic nonspecific low back pain.
