INTRODUCTION: To evaluate the acute effect of scapular mobilization with associated myofascial release compared to scapular mobilization without myofascial release on butterfly stroke sports performance. DESIGN: Randomized clinical trial. METHOD: Pilot study that non-probabilistically convenience sampling that selected butterfly swimmers who were simply randomized into three groups to receive the standard protocol (scapular mobilization with release of the subscapularis muscle by the lateral edge of the scapula and rib cage detachment) in intervention group (IG), sham group (SG) (scapular mobilization without subscapularis muscle release and without rib cage detachment) or no intervention in control group (CG). We evaluated the stroke frequency, length, and average speed of 30 swimmers using the 8.15 Kinovea® motion analysis system. RESULTS: The findings showed that, compared to the CG and IG, the SG showed a significant reduction in mean velocity (p = 0.002; p = 0.02, respectively), stroke frequency (p = 0.002; p = 0.003, respectively), and stroke length (p = 0.01; p = 0.05, respectively). DISCUSSION: The results showed that manual therapy through scapular mobilization without associated myofascial release with detachment of the scapula from the rib cage worsened the swimming efficiency indicators even after 30 min of application of the technique. The limitations of the studies are related to the sample size, the risk of non-probabilistic contraction bias and the lack of blinding of the evaluators. Thus, the results of this study should be evaluated with caution.

To investigate whether myofascial reorganization® in the trapezius muscle (MRT) improves peripheral muscle oxygenation and pain tolerance and decreases neck disability index (NDI) scores in individuals with and without nonspecific neck pain (NP) using a double-blind randomized controlled trial. Seventy-five subjects were equally and randomly assigned to three groups: the intervention groups (experimental [EG] and sham sSG]) and the control group (CG). Several inclusion criteria were applied to the intervention groups: male or female, aged 18-32 years, self-reported NP in the last 3 months without a defined cause; at least "soft" pain in session 1 of the NDI, and at least a score of 1 on the Visual Analogue Scale (VAS). The CG was required to have NDI and VAS scores of 0 at recruitment. Intervention: The EG underwent MRT for 10 min, once a week for 6 weeks. Patients with NP in the SG underwent classical massage for the same duration and frequency. Patients in the CG had no pain and underwent no intervention. Data collection was performed using the NDI Questionnaire, a pressure algometer for pain evaluation, and near-infrared spectroscopy for muscle oxygenation measurements. It was registered as NCT03882515 at ClinicalTrials.gov. The NDI score in both the EG (p<0.001) and SG (p<0.001) decreased after 6 weeks of intervention compared to the CG. The CG demonstrated a lower basal tissue saturation (TSI) index than the EG (p<0.001) and SG (p = 0.02). The EG demonstrated higher oxyhemoglobin values than the SG (p<0.001) and CG (p = 0.03). The CG had higher pain tolerance than the EG (p = 0.01) and SG (p<0.001) post-intervention. MRT increased trapezius muscle oxygenation after 6 weeks of intervention.

BACKGROUND: Patellofemoral pain (PFP) is typically accompanied by changes in movement pattern. However, it is unclear if these changes persist in the remission phase of symptoms. Investigating movement patterns in individuals in remission phase of PFP may help to further guide the rehabilitation process and to understand whether changes are due to high levels of pain or related to other factors. PURPOSE: To compare 3D kinematics during walking and the single leg squat (SLS) between individuals with history of PFP in remission phase and a control group without history of lower limb injuries and PFP. STUDY DESIGN: Cross-sectional case-control study. METHODS: Individuals with onset of PFP for at least one year and in phase of remission of symptoms (experimental group [EG]; n=13, 30±8 years) were compared to a control group (CG, n=13, 28±7 years). A 10-camera motion analysis system (Vicon-Nexus®) was used to record 3D ankle, knee, hip and trunk angles during walking and SLS. RESULTS: The EG presented less ankle dorsiflexion, knee and hip flexion during the stance phase of walking compared to the CG (p=0.005, large effect size ηp2 = 0.141). During the SLS, no between-group differences were observed for the ankle, knee and hip angles at the peak of knee flexion (p>0.05). A trend for increased trunk range of movement in the EG compared to the CG was observed (p=0.075, medium effect size ηp2 = 0.127). CONCLUSION: The results of this study indicate less movement in the sagittal plane during walking, and a trend towards more movement of the trunk during SLS in the EG compared to the CG. The participants of the EG had minimal symptoms, to the point of not classifying them as pathological. However, the between-group differences suggest that even in the remission phase, kinematic differences persist for some reason and may contribute to the recurring pain in PFP individuals. LEVEL OF EVIDENCE: Level 3.

Objetivos: Avaliar as variações antropométricas e a distribuição de pressão plantar dos pés durante o ciclo gravídico-puerperal de uma paciente.Descrição do caso: Este estudo descritivo-exploratório analisou uma gestante por meio de oito avaliações, seis durante a gestação (na 26ª, 28ª, 30ª, 32ª, 34ª e 36ª semana da gestação) e duas no puerpério (10º e 50º dia após o parto). Foram avaliadas seis variáveis antropométricas dos pés e tornozelos. Por meio do escaneamento dos pés, obteve-se indiretamente o ângulo da impressão plantar. O Sistema Pedar-Mobile (Novel GmbH), avaliou o índice do arco plantar e o pico de pressão máxima plantar tanto estático como dinâmico. Durante o período gestacional o comprimento e o perímetro do mediopé direito apresentaram-se maiores do que o esquerdo. Ocorreu diminuição do ângulo plantar com a evolução da gestação. A variação do índice do arco plantar na tarefa estática mostrou variação mínima em todo o período avaliado, enquanto na dinâmica demonstrou diminuição progressiva dos valores durante a gestação e aumento no período puerperal. As médias dos picos de pressão plantar na tarefa dinâmica foram mais elevadas durante o período gestacional em comparação ao puerpério.Conclusões: Estes dados mostram alterações nas características biomecânicas dos pés no ciclo gravídico-puerperal, ressaltando aumento na perimetria e diminuição do arco plantar.


Aims: To evaluate anthropometric variations and distribution of plantar pressure during pregnancy and puerperium. Case description: In this descriptive exploratory study, a pregnant woman was submitted to eight assessments, six of them during pregnancy (at 26, 28, 30, 32, 34, and 36 weeks of gestation) and two in the postpartum period (at 10 and 50 days postpartum). Six foot and ankle anthropometric parameters were assessed. The footprint angle was indirectly obtained by scanning electron microscopy. The Pedar-Mobile (Novel GmbH) system assessed the plantar arch index and maximum peak plantar pressure both statically and dynamically. The right mid-foot length and circumference were larger than those of the left mid-foot during the gestational period. Footprint angle decreased as the gestational period progressed. The plantar arch index in static footprints varied slightly throughout the study period, but it progressively decreased during pregnancy and increased in the postpartum period. The average peak plantar pressure in dynamic footprints was higher during pregnancy than in the postpartum period.Conclusions: These data reveal changes in the biomechanics of feet during pregnancy and puerperium, indicating an increase in circumference measurement and a reduction in plantar arch.

Objetivos: Os objetivos deste estudo foram caracterizar e descrever a postura de idosos praticantes de atividade física.Métodos: Foram estudados idosos com idade entre 60 e 80 anos, do Grupo de Estudos da Terceira Idade da Universidade do Estado de Santa Catarina, que praticavam atividade física por pelo menos dois dias na semana. Os dados foram obtidos por fotogrametria computadorizada com o Software para Avaliação Postural (SAPO) nas vistas laterais, anterior e posterior. Foi realizada estatística descritiva por meio de média e desvio padrão.Resultados: A amostra foi composta por 40 idosos, sendo 34 mulheres e seis homens. As características posturais encontradas na vista anterior foram rotação da cabeça, elevação de ombros, escápula e pelve e rotação interna dos membros inferiores; na vista posterior foi valgismo de retropé, tanto direito quanto esquerdo; e, na vista lateral, foram anteriorização da cabeça, inclinação do tronco para trás, extensão de quadril, anteversão pélvica e joelhos fletidos.Conclusões: Algumas características posturais observadas nos idosos ativos foram semelhantes àquelas encontradas no envelhecimento normal. No entanto, a inclinação do tronco para trás e a extensão do quadril diferiram da postura flexora típica dos idosos. Acreditamos que estas características sejam consequência dos exercícios físicos que promovem o fortalecimento da musculatura extensora, importante para a manutenção da postura correta...


Aims: The purposes of this study were to characterize and to describe the posture of elderly who practice physical activities.Methods: Elderly participants of the Third Age Study Group at the Santa Catarina State University, between 60 and 80 years old, who practiced physical activity for at least two days a week, were studied. Data were obtained through computerized photogrammetry using the Postural Assessment Software (PAS/SAPO) in anterior, posterior and side views. Descriptive statistics were performed by using the mean and standard deviation.Results: The sample consisted of 40 subjects, 34 women and six men. Postural characteristics in the anterior view were head rotation, lifting shoulders, scapula and pelvis, and internal rotation of the lower limbs; in the posterior view were right and left valgus hindfoot; and, in the side view, were the head forward, backward inclination of the trunk, hip extension, pelvic anteversion and flexed knees.Conclusions: Some postural features observed in seniors engaged in physical activity were similar to those found in normal aging. However, inclination of trunk backward and extension of the hip differed from the typical flexor posture of the elderly. We believe that these features are a consequence of physical exercises that promote the strengthening of the extensor muscles, important for maintaining the correct posture...
