The modulation of bone ECM is regulated by several types of matrix metalloproteinase (MMP); however, MMP-2 activity in different trabecular bones in response to resistance training (RT) has been neglected. Remodeling differs in different bones under the application of the same mechanical loading. Thus, we investigated the effects of 12 weeks of RT on MMP-2 activity in the lumbar vertebra (L6), tibia, and femur of young (3 months) and older rats (21 months).Methods: Twenty Wistar rats were divided into four groups (five animals per group): young sedentary or trained and older sedentary or trained. The 12-week RT consisted of climbing a 1.1-m vertical ladder three times per week with progressive weights secured to the animals’ tails. The animals were killed 48 h after the end of the experimental period. The MMP-2 activity was assessed by the zymography method.Results: The aging process induced lower MMP-2 activity in the lumbar vertebrae and tibia (p=0.01). RT upregulated pro, intermediate, and active MMP-2 activity in the tibia of young rats (p=0.001). RT also upregulated pro and active MMP-2 activity in the lumbar vertebrae and tibia with advancing age (p=0.01). There was no significant difference (p> 0.05) between groups for MMP-2 of the femur, regardless of age and RT.Conclusion: The aging process impairs MMP-2 activity, but RT is a potential therapeutic approach to minimize the deleterious effects of ECM degeneration in different aged bones. Distinct MMP-2 responses to exercise training may result in specific remodeling processes.Keywords: senescent, skeletal system, remodeling, matrix metalloproteinase, exercise

The abdominal drawing-in maneuver (ADIM) is a clinical tool used for identifying preferential activity of deep abdominal muscles. However, concurrent validity and reproducibility of palpation during the ADIM has not been formally investigated. The aims of this study were (1) to assess intra- and interrater reliability of manual palpation during the ADIM, and (2) to determine the concurrent validity of manual palpation during the ADIM by calculating preferential activation ratio cut-off as assessed with ultrasound imaging (RUSI). Thirty-two subjects (n = 16 patients with nonspecific low back pain and 16 comparable healthy individuals) performed the ADIM in a supine hook-lying position. Two experienced assessors evaluated the presence or absence of preferential contraction of the deep abdominal muscles by palpation during the ADIM on 2 different days. Intrarater (test-retest) and interrater reliability of palpation were calculated using Cohen’s kappa coefficients. Muscle thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles at rest and during the ADIM were also measured. TrA-Contraction Ratio (TrA-CR), TrA-Preferential Activation Ratio (TrA-PAR), and Modified-TrA-PR (M-TrA-PAR) were calculated. The concurrent validity of manual palpation was determined using the correlation between manual palpation and imaging and by calculating ROC curve (operating characteristics curve), Youden index, and sensitivity and specificity. Intra- and interrater reliability of manual palpation during the ADIM was excellent (k: 0.82–1.00) and good to excellent (k: 0.71–1.00), respectively. Interrater reliability for muscle thickness ranged from good to excellent (ICC3,1 0.79–0.91). Manual palpation and TrA ratio showed low to moderate correlations (r: 0.36–0.60). When evaluating the diagnostic accuracy of manual palpation, the best predictive model (ROC value: 0.89, p &lt, 0.001) for correct a preferential contraction of TrA was obtained when the M-TrA-PAR was ≥0.08 (sensitivity: 0.95–1.00, specificity: 0.62). Good to excellent intra- and interrater reliability of manual palpation was found during the ADIM in both patients and healthy groups. Manual palpation showed concurrent validity for identifying the preferential activity of the TrA muscle supporting its use in clinical practice.

Worldwide, the burden of musculoskeletal disorders is increasing with great variations between-countries, which makes it difficult for policymakers to provide resources and adequate interventions in order to provide for their appropriate management. Thus, musculoskeletal disorders remain a public health problem and their incidence and trend is increasing for some specific conditions. Indeed, nutrients and biological biomarkers play a key role in the prognosis, diagnosis and health status of patients suffering from musculoskeletal conditions, being the main indicators for understanding biological processes as well as tailoring therapeutic interventions and nutritional programs in patients with musculoskeletal disorders. Thus, the purpose of this Special Issue was to provide an update on the state of the art, through current reviews as well as new insights and interventions, about the main role of nutrients and biomarkers in patients who suffer from musculoskeletal conditions from a multidisciplinary point of view.

SUMMARY Using computer-aided engineering (CAE) in the concept design stage of automobiles has become a hotspot in human factor engineering research. Based on human musculoskeletal biomechanical computational software, a seated human-body musculoskeletal model was built to describe the natural sitting posture of a driver. The interaction between the driver and car in various combinations of seat-pan/back-rest inclination angles was analyzed using an inverse-dynamics approach. In order to find out the “most comfortable” driving posture of the seat-pan/back-rest, the effect of seat-pan/back-rest inclination angles on the muscle activity degree, and the intradiscal L4-L5 compression force were investigated. The results showed that a much larger back-rest inclination angle, approximately 15°, and a slight backward seat-pan, about 7°, may relieve muscle fatigue and provide more comfort while driving. Subsequently, according to the findings above, a preliminary driving-comfort function was constructed. RESUMO O uso de engenharia assistida por computador (CAE) na fase de projeto do conceito do automóvel tornou-se um ponto de acesso na pesquisa de fatores humanos. Com base no software computacional biomecânico musculoesquelético humano, foi construído um modelo musculoesquelético sentado para descrever a postura sentada natural de um condutor. A interação entre um motorista e um carro em várias combinações de ângulos de inclinação do assento-pan/encosto foi analisada usando uma abordagem dinâmica do verso. A fim de descobrir a postura de condução “mais confortável” do assento-pan/encosto, o efeito dos ângulos de inclinação do assento-pan/dorso sobre o grau de atividade muscular e a força de compressão intradiscal L4-L5 foi investigado. Os resultados mostraram que um ângulo de inclinação para trás muito maior, aproximadamente 15°, e um ligeiro assento-pan para trás, cerca de 7°, pode aliviar a fadiga muscular e levar a dirigir em uma posição confortável. Posteriormente, de acordo com as conclusões acima expostas, foi construída uma função preliminar de conforto ao dirigir.

Subungual osteochondroma (SO) is an infrequent and non-malignant bone tumour of the distal phalanx, especially prominent in paediatric populations. The aim of this research was to describe a case series of paediatric feet with SO which received surgical treatments. The secondary purpose was to compare these descriptive data by sex distribution. Methods: Twenty-three paediatric feet with SO confirmed by clinical or radiological features received surgical treatment. Socio-demographic (age, sex, height, weight and BMI) and clinical features (side, location, tumour or pain presence, and nail lift before surgery, as well as recurrence and adverse effects at one month after intervention) were reported. Results: Regarding clinical features before intervention, the most frequent locations of SO were the first toe (86.8%) and the right lower limb (56.5%). In addition, the presence of the tumour, pain and nail lift showed a prevalence of 91.3%, 69.5% and 47% of the study sample, respectively. Considering clinical features at one month after intervention, the most frequent adverse effect was the pain presence (69.5%). In addition, one case (4.4%) presented ulceration. Only one patient (4.4%) suffered from recurrence with a new tumour. There were not statistically significant differences by sex distribution (p &gt, 0.05). Conclusions: This novel study showed that surgery treatment for SO in paediatric populations presented a very low recurrence degree with minor adverse effects and without differences by sex distribution. Thus, further randomized clinical trials should be carried out in order to determine the effectiveness of this intervention in this special population.

Nowadays, the use of insoles in sport practice have been recognized to decrease the foot and lower limb injury patterns. The aim of this study was to analyse the effect of four types of hardness insoles (HI) in the activity patterns of the hip and thigh muscles (HTM) in motoriders during motorcycling sport. The study was a crossover trial. Subjects were elite motoriders. The mean age was 33 &plusmn, 5.14 years. Electromyography (EMG) of hip and thigh muscles (HTM) data was registered via surface while subjects were riding on an elite motorcycle simulator. Subjects had to complete different tests with randomly hardest insoles (HI): 1: only polypropylene (58&deg, D Shore), 2: Polypropylene (58&deg, D Shore) with selective aluminium in hallux and metatarsal heads (60 HB Brinell hardness), 3: Ethylene vinyl acetate (EVA) (52&deg, A Shore), and finally, 4: Ordinary EVA (25&deg, A Shore) as the control. EMG patterns of the HTM, riding on an elite motorcycle simulator, showed the lowest peak amplitude with the insoles with polypropylene and selective aluminium. Using the hardest insoles in our study (selective aluminium) the EMG amplitude peaks decreased in all HTM.

We are currently experiencing a vitamin D (VITD) deficiency pandemic across the world. Athletes have the same predisposition to low levels of vitamin D, the majority of its concentrations being below 20 ng/mL in a wide range of sports, especially in the winter months. Vitamin D is important in bone health, but recent research also points out its essential role in extraskeletal functions, including skeletal muscle growth, immune and cardiopulmonary functions and inflammatory modulation, which influence athletic performance. Vitamin D can also interact with extraskeletal tissues to modulate injury recovery and also influence the risk of infection. The data presented in this paper has triggered investigations in relation to the importance of maintaining adequate levels of vitamin D and to the possible positive influence supplementation has on immune and musculoskeletal functions in athletes, benefiting their performance and preventing future injuries. The objective of this review is to describe the latest research conducted on the epidemiology of vitamin D deficiency and its effects on sports performance and musculoskeletal health.

Introduction: The impairment of muscle strength and fatigue in leprosy remains a problem that requires careful attention to avoid or minimize its progression, as well as prevention of disabilities and deformities. Objective: To investigate the maximum voluntary contraction and time to muscle fatigue in leprosy patients. Method: A total of 21 leprosy patients and 21 healthy subjects completed the sample. The method used to determine the maximum voluntary contraction (MVC) of the handgrip followed the recommendation of the American Society of Hand Therapists with the use of a hydraulic hand grip dynamometer. The test was performed three times with each hand, with a time interval of 60 seconds between successive trials. The subject was instructed to perform a maximal isometric force against the dynamometer for 5 seconds. The peaks were recorded and used for the fatigue test. For the fatigue test, we recorded the electromyogram of the forearm muscles to offline determine the onset time for the muscle contraction (14 bits, Miograph 2 USB®, Miotec, Brazil). Results: Leprosy patients had lower MVC compared with healthy subjects (p > 0.05), both in the dominant and the non-dominant hands. The time to fatigue in the leprosy and control groups was similar (p < 0.05). We observed that leprosy patients had more contractions than the healthy subjects (22.6 ± 11.8 contractions for the leprosy group vs. 12.3 ± 6.9 contractions for the control group, p > 0.05). Conclusion: Multibacillary leprosy patients lost muscle force without modifying the resistance to fatigue. Resumo Introdução: O comprometimento da força muscular e a fadiga na hanseníase continuam sendo problemas que requerem cuidadosa atenção para evitar ou minimizar sua progressão, bem como prevenir incapacidades e deformidades. Objetivo: Avaliar a força muscular e o tempo até a fadiga em pacientes com hanseníase Método: Vinte e um pacientes com hanseníase e 21 indivíduos saudáveis completaram a amostra. O método utilizado para determinar a contração voluntária máxima (CVM) da força de preensão palmar seguiu a recomendação da Sociedade Americana de Terapeutas da Mão com o uso de um dinamômetro de preensão manual. O teste foi realizado três vezes em cada mão, com intervalo de tempo de sessenta segundos entre tentativas sucessivas. O sujeito foi instruído a realizar força isométrica máxima contra o dinamômetro durante cinco segundos. Os picos foram registrados e usados para o teste de fadiga. Para o teste de fadiga, registrou-se o eletromiograma dos músculos do antebraço para determinar off-line o tempo de início da contração muscular (14 bits, Miograph 2 USB ® , Miotec, Brasil). Resultados: Os pacientes com hanseníase apresentaram menor CVM em relação aos saudáveis (p < 0,05) nas mãos dominante e não dominante. Não houve diferença no tempo de fadiga entre os grupos hanseníase e controle (p > 0,05). Foi observado que os pacientes com hanseníase tinham mais contrações do que os saudáveis (22,6 ± 11,8 contrações para o grupo com hanseníase vs. 12,3 ± 6,9 para o grupo controle, p < 0,05). Conclusão: Pacientes com hanseníase multibacilar apresentaram perda de força muscular sem modificação da resistência à fadiga. Resumen Introducción: El compromiso de la fuerza muscular y la fatiga en la lepra sigue siendo un problema que requiere atención cuidadosa para evitar o minimizar su progresión, así como la prevención de incapacidades y deformidades. Objetivo: Evaluar la fuerza muscular y el tiempo hasta la fatiga de pacientes con lepra. Método: Veintiún pacientes con lepra y 21 sujetos sanos completaron la muestra. El método utilizado para determinar la contracción voluntaria máxima (CVM) de la fuerza de asimiento palmar siguió la recomendación de la Sociedad Americana de Terapeutas de la Mano con el uso de un dinamómetro de asimiento manual. La prueba se realizó tres veces con cada mano, con un intervalo de tiempo de 60 segundos entre intentos sucesivos. El sujeto fue instruido a realizar una fuerza isométrica máxima contra el dinamómetro durante 5 segundos. Los picos se registraron y se utilizaron para la prueba de fatiga. Para la prueba de fatiga, registramos el electromiograma de los músculos del antebrazo para determinar fuera de línea el tiempo de inicio de la contracción muscular (14 bits, Miograph 2 USB ® , Miotec, Brasil). Resultados: Los pacientes con lepra presentaron menor CVM con relación a los sanos (p < 0,05) en las manos dominante y no dominante. No hubo diferencia en el tiempo de fatiga entre los grupos de lepra y control (p > 0,05). Se observó que los pacientes con lepra tenían más contracciones que los sanos (22,6 ± 11,8 contracciones para el grupo con hanseniasis frente a 12,3 ± 6,9 para el grupo control, p < 0,05). Conclusión: Pacientes con hanseniasis multibacilar presentaron pérdida de fuerza muscular sin modificación de la resistencia a la fatiga.

Rigidity is one of the cardinal symptoms of Parkinson’s disease (PD). Present in up 89% of cases, it is typically assessed with clinical scales. However, these instruments show limitations due to their subjectivity and poor intra- and inter-rater reliability. To compile all of the objective quantitative methods used to assess rigidity in PD and to study their validity and reliability, a systematic review was conducted using the Web of Science, PubMed, and Scopus databases. Studies from January 1975 to June 2019 were included, all of which were written in English. The Strengthening the Reporting of observational studies in Epidemiology Statement (STROBE) checklist for observational studies was used to assess the methodological rigor of the included studies. Thirty-six studies were included. Rigidity was quantitatively assessed in three ways, using servomotors, inertial sensors, and biomechanical and neurophysiological study of muscles. All methods showed good validity and reliability, good correlation with clinical scales, and were useful for detecting rigidity and studying its evolution. People with PD exhibit higher values in terms of objective muscle stiffness than healthy controls. Rigidity depends on the angular velocity and articular amplitude of the mobilization applied. There are objective, valid, and reliable methods that can be used to quantitatively assess rigidity in people with PD.

Background: Hallux valgus (HV) has been previously associated with psychological disorders. Thus, the purposes of this study were to associate kinesiophobia and pain intensity with HV deformity degrees, as well as predict kinesiophobia and pain intensity based on HV deformity and demographic features. Methods: A cross-sectional study was carried out recruiting 100 subjects, who were divided into HV deformity degrees, such as I-no HV (n = 25), II-mild (n = 25), III-moderate (n = 25), and IV-severe (n = 25) HV. Kinesiophobia total and domains (activity avoidance and harm) scores and levels were self-reported by the Tampa Scale of Kinesiophobia (TSK-11). Pain intensity was self-reported by the numeric rating scale (NRS). Results: Statistically significant differences (p &lt, 0.01, &eta, 2 = 0.132&ndash, 0.850) were shown for between-groups comparison of kinesiophobia total and domain scores (activity avoidance and harm) and levels, as well as pain intensity among HV deformity degrees. Post hoc comparisons showed statistically significant differences with a large effect size (p &lt, 0.05, d = 0.85&ndash, 4.41), showing higher kinesiophobia symptoms and levels and pain intensity associated with greater HV deformity degrees, especially for III-moderate and/or IV-severe HV deformity degrees versus I-no HV and/or II-mild deformity degrees. Both statistically significant prediction models (p &lt, 0.05) for kinesiophobia (R2 = 0.300) and pain intensity (R2 = 0.815) were predicted by greater HV deformity degree and age. Conclusions: Greater kinesiophobia symptoms and levels and pain were associated with higher HV deformity degrees, especially severe and/or moderate HV with respect to no and/or mild HV. The kinesiophobia and pain intensity were predicted by greater HV deformity degree and age.

Background: People with Parkinson&rsquo, s disease (PD) present deficits of the active range of motion (ROM), prominently in their trunk. However, if these deficits are associated with axial rigidity, the functional mobility or health related quality of life (HRQoL), remains unknown. The aim of this paper is to study the relationship between axial ROM and axial rigidity, the functional mobility and HRQoL in patients with mild to moderate PD. Methods: An exploratory study was conducted. Non-probabilistic sampling of consecutive cases was used. Active trunk ROM was assessed by a universal goniometer. A Biodex System isokinetic dynamometer was used to measure the rigidity of the trunk. Functional mobility was determined by the Get Up and Go (GUG) test, and HRQoL was assessed with the PDQ-39 and EuroQol-5D questionnaires. Results: Thirty-six mild to moderate patients with PD were evaluated. Significant correlations were observed between trunk extensors rigidity and trunk flexion and extension ROM. Significant correlations were observed between trunk flexion, extension and rotation ROM and GUG. Moreover, significant correlations were observed between trunk ROM for flexion, extension and rotations (both sides) and PDQ-39 total score. However, these correlations were considered poor. Conclusions: Trunk ROM for flexion and extension movements, measured by a universal goniometer, were correlated with axial extensors rigidity, evaluated by a technological device at 30&deg, /s and 45&deg, /s, and functional mobility. Moreover, trunk ROM for trunk flexion, extension and rotations were correlated with HRQoL in patients with mild to moderate PD.

Customized foot insoles (CFI) have been recognized to reduce the prevalence of foot disorders in sport. The aim of this study was to evaluate the effect of four types of CFI on the activity patterns of the lower limb muscles (LLM) in healthy people during sport motorcycling. Methods: This was a cross-over trial (NCT03734133. Participants were recruited from an outpatient foot specialist clinic. Their mean age was 33 &plusmn, 5.14 years. While participants were sport motorcycling in a simulator, the electromyography (EMG) function was registered for LLM via surface electrodes. Participants completed separate tests while wearing one of four types of CFI: (1) only polypropylene (58&deg, Shore D), (2) selective aluminum (60 HB Brinell hardness) in metatarsal and first hallux areas and polypropylene elsewhere (58&deg, Shore D), (3) ethylene vinyl acetate (EVA) (52&deg, Shore A), and (4) standard EVA (25&deg, Shore A) as the control. Results: The activity patterns of the LLM while sport motorcycling showed significantly lower peak amplitude for the selective aluminum CFI than the other types of CFI. Conclusion: EMG amplitude peaks for several LLM were smaller for the hardest CFI (selective aluminum 60 HB Brinell hardness) than the other CFIs (polypropylene 58&deg, Shore D, EVA 52&deg, Shore A, and standard EVA 25&deg, Shore A), except for the fibularis longus in right curves that is increased when the knee touches the road increasing the stability.

Purpose: To compare and quantify with ultrasound imaging (USI) the inter-recti distance (IRD), rectus abdominis (RA), external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), and multifidus thickness and the RA and multifidus cross-sectional area (CSA) between individuals with and without chronic mid-portion Achilles tendinopathy (AT). Methods: A cross-sectional study. A sample of 143 patients were recruited and divided into two groups: A group comprised of chronic mid-portion AT (n = 71) and B group composed of healthy subjects (n = 72). The IRD, RA, EO, IO, TrAb, and multifidus thickness, as well as RA and multifidus CSA, were measured by USI. Results: USI measurements for the EO (p = 0.001), IO (p = 0.001), TrAb (p = 0.041) and RA (p = 0.001) thickness were decreased as well as IRD (p = 0.001) and multifidus thickness (p = 0.001) and CSA (p = 0.001) were increased for the tendinopathy group with respect the healthy group. Linear regression prediction models (R2 = 0.260 − 0.494; p < 0.05) for the IRD, RA, EO, and IO thickness (R2 = 0.494), as well as multifidus CSA and thickness were determined by weight, height, BMI and AT presence. Conclusions: EO, IO, TrAb, and RA thickness was reduced and IRD, multifidus thickness and CSA were increased in patients with AT.

The white-footed tamarin (Saguinus leucopus) is an endangered endemic primate of Colombia, mainly due to the deforestation of its habitat and illegal trade, which generates a high incidence of these animals in wildlife care centres. Musculoskeletal system disorders in S. leucopus are one of the most common diseases and therefore the aim of this study was to contribute to the morphologic studies with a morphometric, anatomic and radiographic description of the scapula in this species to provide a basis for medical interventions, surgical approaches, radiologic diagnoses and comparative functions of this bone. Gross dissections of each scapular region were made in eight specimens without a diagnosis of osteomuscular disease. These specimens died from natural cases in the wildlife care centres of the Corporacion Autonoma Regional de Caldas (CORPORCALDAS); after necropsy their carcasses were fixed with 10% formaldehyde, 5% mineral oil and 1% phenic acid in these centres over the course of at least 1 week. X-rays of the scapula were taken in the small animal clinic of the Universidad del Tolima, and morphometric data of the scapulae were obtained with a digital calliper. The scapula of the white-footed tamarin was a flat triangular bone with a deep scapular notch in its cranial margin, where there was a cranial transverse scapular ligament that was absent in two specimens. The coracoid process was highly developed, medially covering the humeral joint. The dorsal margin was covered by the scapular cartilage, which was highly developed in the caudal angle. In the dorsal fourth of the caudal margin, there was a surface from which the m. teres major originated. The lateral surface had a scapular spine with a long hamatus process of the acromion until the lateral part of the humeral joint. The infraspinatus fossa was wider than the supraspinous fossa. On the costal surface, the subscapular fossa was formed by three subscapular lines and one subscapular ridge, the latter helping to form the surface for the m. teres major. In the two radiographic views, caudocranial to the scapula and dorsoventral to the thorax, the scapular spine, acromion, coracoid process, scapular incisura, supraglenoid tubercle, caudal margin, subscapular ridge, and the joints with the clavicle and the humerus could be observed. The scapula of the white-footed tamarin presented bony reliefs that share characteristics with other primates but also with domestic mammals due to its quadrupedal locomotion, which allowed us to correlate its morphologic adaptation with its quadrupedal arboreal displacement.

Objective A cross-sectional study was conducted to investigate the role of whole-body vibration as a risk factor for spinal musculoskeletal symptoms among agricultural pilots. Method The study was conducted in two stages that included measuring the pilots’ exposure to whole-body vibration during the flight procedures and applying a self-administered questionnaire about musculoskeletal symptoms of the spine. Results None of the four aircraft texted exposed the pilot above the Exposure Limit Value (ELV) established by the standards. However, in a few specific situations, two of them exceeded the Exposure Action Value (EAV). About 62% of the pilots who operated these aircraft reported some musculoskeletal symptoms of the spine in the last few 12 months. Conclusion Using the data from this study, it was possible to calculate the odds ratio of the agricultural pilot suffering low back pain, based on eight personal and work-related factors. Relevance for the industry Based on the results of the present study, it was possible to define strategies to reduce whole-body exposure in agricultural aircraft and, consequently, improve the pilots’ health. Strategies included management of the exposure and aircraft improvement.

A identificação das idosas cuidadoras se deu por meio de consulta aos prontuários da pessoa dependente, e a entrevista ocorreu no período de março a junho de 2017. Os dados foram sistematizados com base na Análise de Conteúdo. Resultados: Participaram do estudo seis idosas cuidadoras de pessoas com capacidade funcional comprometida. Emergiram três categorias: dor osteomuscular relacionada ao cuidado; problemas de saúde relacionados à somatização do sentimento vivido; e deficit do autocuidado em virtude do cuidado com o outro. Conclusão: O estudo revelou as consequências de cuidar de familiares dependentes para a saúde de idosas cuidadoras, sendo essencial uma gestão que prime pelo cuidado do cuidador no sentido de prevenir e/ou reduzir problemas de saúde, principalmente no tocante ao sistema osteomuscular.

Objective: The aim was to analyze effects of a percutaneous neuromodulation (PNM) treatment on the radial nerve, regarding pain, functionality, electrophysiologic excitability, and morphology, in patients with chronic lateral epicondylalgia (LE). Methods: Twenty-four patients with chronic unilateral elbow pain were recruited for this preliminary study and were divided into two groups: control (n = 12) and PNM group (n = 12). The subjects in the PNM group received percutaneous peripheral neurostimulation with an acupuncture needle that was located next to the nerve with ultrasound guidance. Pain using a numerical rating scale (NRS), functional ability using patient-rated tennis elbow evaluation (PRTEE), radial nerve cross-sectional area measured by ultrasound, and chronaxie and accommodation index (AI) measured by the strength–duration curve were evaluated. Results: Both groups showed no differences in the baseline measurements (all p = 0.001). However, at the end of the treatment, there were significant differences between groups since only the PNM group significantly improved their values compared to their baseline values: level of pain and cross-sectional area (CSA) values showed a significant decrease while the PRTEE scores showed a significant improvement. Then, regarding AI, the PNM group showed significant improvement for the electrophysiologic nerve excitability pattern, reporting normal function in all radial nerves after treatment (p = 0.001). However, chronaxie values always reported similar values with no differences between groups (p &gt, 0.05), Conclusion: Ultrasound-PNM technique may be an interesting therapeutic tool for the treatment of chronic LE due to the improvement in the level of pain, functionality, nerve morphology, and excitability in this population.

ResumoObjetivoAvaliar os efeitos do ultrassom terapêutico e/ou alongamento, na morfologia após contusão muscular em ratos.MétodosRatos Wistar machos (n=35, 8‐9 semanas, 271±14g) foram divididos em cinco grupos: Grupo Controle (GC=3); Grupo Lesão (GL=8); Grupo Lesão+Ultrassom (GLUS=8); Grupo Lesão+Alongamento (GLA=8); Grupo Lesão+Ultrassom+Alongamento (GLUSA=8). A aplicação do ultrassom no GLUS e GLUSA foi feita do terceiro ao sétimo dia, pulsado 50%, 0,5W/cm2, 5min. Do décimo ao vigésimo primeiro dia foi feito o alongamento passivo no GLA e GLUSA, em quatro repetições de 30 s, com 30 s de intervalo, cada repetição. Após 22 dias, os ratos foram pesados e os músculos de ambas as patas foram retirados para análise do peso e comprimento muscular, número e comprimento dos sarcômeros, área de secção transversa e porcentagem de colágeno.ResultadosO peso corporal final foi maior do que o inicial em todos os grupos. O número de sarcômeros foi maior no GLA em relação ao GLUS e no GLUSA em relação ao GLUS e ao GC; o comprimento dos sarcômeros foi maior no GLUS comparado com o GLA (p

RESUMO As adaptações da matriz extracelular, que está intimamente ligada à manutenção da integridade e do desempenho do sistema musculoesquelético, não estão consensualmente descritas na literatura após recarga por desuso. O objetivo deste estudo foi analisar a área de tecido conjuntivo perimisial e de secção transversa das fibras musculares nos músculos sóleo e plantar de ratas imobilizadas e posteriormente reabilitadas por protocolos de alongamento e exercício excêntrico. A expressão do tecido conjuntivo perimisial de ambos os músculos estudados não apresentou diferença significativa após o procedimento de imobilização e treinamento. O treino excêntrico aplicado por 10 dias foi suficiente para recuperar a área das fibras para o músculo plantar, enquanto a recuperação do músculo sóleo aconteceu somente após o protocolo de 21 dias. RESUMEN No figuran descriptas de manera consensual en la literatura las adaptaciones extracelulares, ligadas al mantenimiento de la integridad y del desempeño del sistema musculoesquelético tras inmovilizaciones. En este estudio se evalúa el área del perimisio del tejido conjuntivo y de la sección transversal de las fibras musculares del sóleo y del plantar en ratas inmovilizadas y después rehabilitadas siguiendo los protocolos de estiramiento y de ejercicio excéntrico. En el área evaluada de ambos músculos no se observaron significativas diferencias tras el procedimiento de inmovilizarlos y entrenarlos. Aplicados en diez días, el entrenamiento excéntrico ha sido suficiente para recuperar el área de las fibras para el músculo plantar, mientras que el músculo sóleo ha tardado veintiuno días en recuperarse. ABSTRACT The adaptations of the extracellular matrix, which is closely related to the maintenance of the integrity and performance of the musculoskeletal system, are not widely described in the literature after rehabilitation due to prolonged disuse. The aim of this study was to analyze the perimysial connective tissue area and the cross-sectional area of muscle fibers in soleus and plantaris muscles of immobilized female rats, later rehabilitated due to stretching and eccentric exercise protocols. The expression of the perimysial connective tissue of both studied muscles did not show significant differences after the procedure of immobilization and training. Eccentric training applied for 10 days was enough to recover the area of fibers for the plantaris muscle, while the recovery of the soleus muscle happened only after the 21-days protocol.

This study analyzed the effects of resistive exercise and/or stretching in the muscle morphology of ovariectomized rats. Seventy-five female Wistar rats (218±22g) were divided into 8 groups: Control (CONTROL, n=5); Ovariectomy/Hysterectomy (OH, n=10): ovariectomized/hysterectomized and then waited 8 weeks for the onset of osteopenia. Stretching (STRET, n=10): manual stretching of the soleus muscle (10 repetitions of 60s), twice weekly; Ovariectomy/Hysterectomy and Stretching (OH+STRET, n=10); Progressive Loading (PL, n=10): 4 sets of 10 repetitions, initial load 50% of body weight, increasing weekly until 70%, three times a week. Progressive Loading and Stretching (PL+STRET, n=10); Ovariectomy/Hysterectomy and Progressive loading exercise (OH+PL, n=10); Ovariectomy/Hysterectomy, Progressive Loading and Stretching (OH+PL+STRET, n=10). Stretching and/or progressive loading were performed for 6 weeks. After 14 weeks, the female rats were euthanized to remove the soleus muscle. The following variables were assessed: body weight; muscle weight and length; number and length of sarcomeres and the muscle fiber cross-sectional area (MFCSA). Comparisons between the groups were performed with ANOVA one-way post hoc Tukey or Kruskall-Wallis (p

Nursing research is expected to provide options for the primary prevention of disease and health promotion, regardless of pathology or disease. Nurses have the skills to develop and lead research that addresses the relationship between genetic factors and health. Increasing genetic knowledge and research capacity through interdisciplinary cooperation as well as the development of research resources, will accelerate the rate at which nurses contribute to the knowledge about genetics and health. There are currently different fields in which knowledge can be expanded by research developed from the nursing field. Here, we present an emerging field of research in which it is hypothesized that genetics may affect bone metabolism. Better insight of genetic factors that are contributing to metabolic bone diseases would allow for focused nursing care and preventive interventions.

Ankle sprains have been defined as the most common injury in sports. The aim of the present study was to investigate the ankle taping for the reduction of ankle dorsiflexion range of motion (ROM) and inter-limb in elite soccer and basketball players U18 in a single training session. Methods: A cross-sectional pilot study was performed on 38 male healthy elite athletes divided into two groups: a soccer group and a basketball group. Ankle dorsiflexion ROM and inter-limb asymmetries in a weight-bearing lunge position were assessed in three points: with no-tape, before the practice and immediately after the practice. Results: For the soccer group, significant differences (p &lt, 0.05) were observed for the right ankle, but no differences for the asymmetry variable. The basketball group reported significant differences (p &lt, 0.05) for the right ankle and symmetry. Conclusions: Ankle taping decreased the ankle dorsiflexion ROM in youth elite soccer and basketball players U18. These results could be useful as a prophylactic approach for ankle sprain injury prevention. However, the ankle ROM restriction between individuals without taping and individuals immediately assessed when the tape was removed after the training was very low.

Background: Based on changes in lung function and musculoskeletal disorders in patients with asthma, this study aimed to compare the tarsal tunnel and fibular bone pressure pain thresholds (PPTs) of patients with asthma and healthy matched-paired controls. Methods: A case-control study was performed. One hundred participants were recruited: 50 asthma patients and 50 healthy matched-paired controls. Bilaterally, tarsal tunnel and fibula bone PPTs were registered. Results: Statistically significant differences (p &lt, 0.01) were shown bilaterally for tarsal tunnel PPT. With the exception of fibula PPT (p &gt, 0.05), asthma patients presented less tarsal tunnel PPT than healthy participants. Statistically significant differences (p &lt, 0.05) were shown for two linear regression prediction models of the right (R2 = 0.279) and left (R2 = 0.249) tarsal tunnels PPTs as dependent variables, and based on sex, group, contralateral tarsal tunnel PPT and ipsilateral fibula PPT as independent variables. Conclusions: The study findings showed that a bilateral tarsal tunnel mechanosensitivity increase is exhibited in patients diagnosed with asthma. The presence of asthma may bilaterally predict the PPT of tarsal tunnel. These findings may suggest the presence of central sensitization in asthma patients, which could clinically predispose them to musculoskeletal disorders, such as tarsal tunnel syndrome.

[Abstract] Generalized ligamentous hyperlaxity (GLH) has been shown to predispose an individual to a number of orthopaedic conditions. Little is known about how GLH affects people’ foot health-related quality of life. This study analyses a sample of people with GLH and people without GLH with normalised reference values of the scores collected with regard to using the Foot Health Status Questionnaire (FSHQ). A total of 100 respondents with mean age of 22.69 ± 3.78 years old, who attended a health centre were classified as GLH (n = 50) or non-GLH (n = 50). The GLH was determined of the patients with and without GLH using assessment with Beighton tool and the scores on the FHSQ were compared. The control group recorded higher scores in the First Section for foot pain, foot function and general foot health, and lower scores in footwear. In the Second Section, they obtained higher scores in social capacity and lower scores in physical activity, vigour and general health. Differences between the two groups were evaluated through a t-test for independent samples, showing statistical significance (P

Olive oil has been demonstrated to enhance various cardiometabolic risk factors. However, to our knowledge, the association between olive oil intake and cortical and trabecular bone microarchitecture has never been evaluated in Spanish women. We aimed to examine the association between olive oil intake and cortical and trabecular bone microarchitecture. We analyzed 523 women aged 50 (9) year, range (23&ndash, 81) year. Participants underwent dual-energy X-ray absorptiometry and peripheral quantitative computed tomography scans. Dietary intake of calcium, vitamin D, energy and olive oil (g/day) were assessed by a self-administered food frequency questionnaire (FFQ). After adjustment for potential confounding factors (calcium (mg/day), vitamin D (&mu, g/day) energy (Kcal/day), age, body mass index (BMI) (kg/m2), menopausal status, and osteoporotic diagnosis (normal, osteopenia, or osteoporosis)), there were significant increases in volumetric bone mineral density (vBMD) (mg/cm3) (p &lt, 0.01) in the group with a higher intake of olive oil. Total, trabecular and cortical bone density were positively correlated with olive oil intake. The dietary intake of olive oil was significantly associated with vBMD in multiple regression analysis, total density: olive oil intake (g/day) standardized &beta, = 0.185 (p &lt, 0.001), trabecular density: olive oil intake (g/day) standardized &beta, = 0.186 (p &lt, 0.001) and cortical density olive oil intake (g/day) standardized &beta, = 0.114 (p = 0.008). We conclude that the dietary intake of olive oil is positively associated with a better vBMD in Spanish women.

Objective: To describe the preoperative localization of musculoskeletal lesions with the radioguided occult lesion localization (ROLL) technique. Materials and Methods: In all cases, computed tomography-guided injection of technetium-99m sulfur colloid was performed, directly into or near the suspicious lesion, up to 36 hours before the surgical procedure. Lesions were detected intraoperatively with a gamma probe. Results: We report the cases of six patients submitted to radioguided surgery, including three patients with bone lesions suspicious for metastasis, two patients suspected of recurrent sarcoma, and one patient with no previous diagnosis who had a nodular lesion on the left leg. Patients tolerated the procedure well, and no complications were associated with the puncture. All marked lesions were easily identified intraoperatively and were excised with clear margins. Conclusion: The ROLL technique was effective in the intraoperative localization of occult musculoskeletal lesions, demonstrating that it is a feasible and promising technique for the surgical exploration of selected cases. Resumo Objetivo: Descrever a localização pré-operatória de lesões musculoesqueléticas utilizando a técnica radioguided occult lesion localization (ROLL). Materiais e Métodos: Em todos os casos foi realizada administração guiada por tomografia computadorizada de enxofre coloidal marcado com tecnécio-99m, diretamente no interior ou adjacente à lesão suspeita, até 36 horas antes do procedimento cirúrgico. As lesões foram localizadas no intraoperatório utilizando um gama-probe. Resultados: São descritos seis casos de pacientes submetidos a cirurgia radioguiada, sendo três pacientes com lesões ósseas suspeitas para metástase, dois pacientes com sarcoma recidivado e um paciente com lesão nodular na perna esquerda sem diagnóstico prévio. Os pacientes toleraram bem o procedimento e não ocorreram complicações. Todas as lesões foram identificadas adequadamente no intraoperatório e ressecadas com margens livres. Conclusão: A técnica ROLL foi efetiva na localização intraoperatória de lesões musculoesqueléticas ocultas, demonstrando que este procedimento é factível e promissor para facilitar a exploração cirúrgica em casos selecionados.

Background: Down syndrome is the most common chromosomal abnormality and a cause of intellectual disability. It is also associated with orthopaedic and musculoskeletal problems of the locomotive apparatus, especially of the feet. These problems are believed to have a harmful effect on health, social functioning, and mobility. In addition, these persons generally don’t have access to podiatric health services, even when their foot problems are well known, because of limited access to healthcare facilities. The goal of our research was to evaluate and compare the foot health status of study participants with and without Down syndrome and to determine whether inadequate footwear is being used with normalized reference values. Methods: A total of 105 participants with and without Down syndrome, with a mean age of 35.71 (SD = 12.93) years, were enrolled in the study. They self-reported demographic data and their clinical characteristic data were recorded. Measurements of their foot and shoe fitting were taken at all stages of the research process. Ninety-two percent of the participants with Down syndrome had foot problems. Results: Only 12 (24%) participants with Down syndrome used bilateral shoes that met the requirements of their feet compared to their controls (50 participants, 90.9% for the right foot; 46 participants, 83.6% for the left foot). Participants with Down syndrome presented statistically significant differences with respect to controls and wore incorrectly sized shoe. Conclusions: Evaluation of foot length and width may prevent development of foot deformities, as well as to improve general Sin financiación 2.468 JCR (2018) Q2, 112/251 Environmental Sciences, 67/186 Public, Environmental & Occupational Health 0.818 SJR (2018) Q2, 37/137 Health, Toxicology and Mutagenesis, 157/562 Public Health, Environmental and Occupational Health No data IDR 2018 UEM

Gran parte de la población no presenta una postura bípeda ideal, presentando un desequilibrio postural y predisponiendo a sufrir trastornos musculoesqueléticos, que pueden ser agravados por las condiciones del trabajo. Objetivo: Determinar la frecuencia de dolor osteomuscular y de las alteraciones posturales del personal de una clínica materno infantil de Lima. Material y métodos: Estudio de tipo transversal. La recolección de información se realizó durante las evaluaciones médicas ocupacionales periódicas de 188 trabajadores. Se evaluaron los segmentos corporales empleándose la cuadrícula postural y la prueba de Adams, mientras que para evaluar los rangos de movimiento articular tanto pasivos como activos, el goniómetro. Para la calificación de la intensidad del dolor se empleó la Escala Visual Analógica del dolor. Resultados: En la evaluación estática la alteración más frecuente fue la elevación de alguno de los hombros en 90,4%, luego la inclinación de cabeza 85,1%, alteraciones en columna lumbar 58%, la rotación de cabeza 49,5% y las alteraciones en pie 41%. Los trabajadores refirieron dolor en la evaluación dinámica de la columna vertebral en 64%, de las extremidades en 30% y en ambas zonas 6%. Conclusiones: Se encontró una frecuencia elevada de alteraciones posturales a predominio de columna vertebral lumbar, tanto sintomáticas y no sintomáticas. La inclusión de la evaluación postural en los exámenes médicos ocupacionales identificó que el 39% de los evaluados con alteraciones posturales estaban asintomáticos, requiriendo acciones preventivas integrales. A great proportion of the population does not exhibit an ideal posture leading to suffer skeletal muscle disorders that can be exacerbated by conditions at work. Objective: To determine the frequency of postural abnormalities among workers of a mother-child clinic in Lima. Methods: A cross-sectional study was conducted during periodic medical evaluations of the center. Body segments were evaluated using postural evaluations and Adam´s test, while range of movement was evaluated with the goniometer. The visual analog pain scale was used to measure intensity of pain. Results: In the static evaluation, the most common disorder was elevation of shoulders in 90.4%, followed by inclination of the head in 85,1%, alterations in the lumbar spine in 58%, head rotation in 49.5%, and foot alterations in 41%. The health workers referred pain at the dynamic evaluation of the spine in 64%, of the extremities in 30% and in both areas in 6%. Conclusions: A high prevalence of postural abnormalities was found in this study with a predominance of both symptomatic and asymptomatic disorders of the spine. The inclusion of postural evaluation in routine occupational examination allowed to detect that 39% of those evaluated had postural defects requiring preventive action.

Alzheimer’s disease (AD) shows a marked presence of physiologic changes and the start or aggravation of underlying diseases such as physical frailty in diverse anatomical regions. It is believed to have a particularly harmful effect on the health of the foot. We examined the foot health status in older persons with AD, with a specific focus on the extent to which people with AD may be using inadequate footwear in old age. Seventy-three community-dwelling people with probable, mild to moderate AD aged 65–95 years were recruited from a center of excellence for AD. A single trained physician evaluated health status and foot conditions. Current shoe and foot length and width measurements were taken using a calibrated Brannock device. The results indicate that sixty-five participants (89.04%) suffered from feet problems. Also, only twenty-two subjects (30.14%) used the correct shoes in width and size related with the morphology of their feet. Fifty-one participants (69.86%) were using incorrect shoes in length or width. The present study revealed that peoples with AD had a high presence of foot health problems. Also, the use of inappropriate shoes revealed measurable differences of association between shoe size and the morphology of the foot.

Introduction: A fracture is a traumatic bone injury that can occur from a variety of causes. Although the repercussions of fractures on the musculoskeletal system are documented, studies with more comprehensive outcomes and later stages of injury are still scarce. Objective: To evaluate the structural and physical-functional adaptations in individuals who suffered unilateral lower limb fractures treated surgically. Methods: Thirty-two patients of both genders, aged between 18 and 59 years, with a diagnosis of unilateral fracture of the lower limb and hospital discharge of at least one year, participated in the study. The affected lower limb was compared to the healthy lower limb of all participants using the outcome measures: vastus lateral muscle thickness (ultrasonography), knee extension and flexion strength (isokinetic dynamometer), ankle dorsiflexion range of motion of the distance from the foot to the wall) and functional fitness of the lower limb (single and triple horizontal jump test). Results: Statistically significant differences were found between the limbs affected and not affected in the measurements of muscle thickness (p = 0.0001), knee extension force (p = 0.0094), dorsiflexion amplitude (p = 0.0004) and functional performance (p = 0.0094, single jump and = 0.0114, triple jump). In all significant outcomes, the values of the affected limb were smaller than that of the non-affected limb. The peak torque of the knee flexor muscles did not show a statistically significant difference between limbs (p = 0.0624). Conclusion: Individuals who have undergone a surgically treated unilateral fracture of the lower limb present important structural and physical-functional late changes in relation to the non-affected limb. Resumo Introdução: Fratura é uma lesão traumática sofrida pelo osso que pode ocorrer por causas diversas. Embora as repercussões das fraturas sobre o sistema musculoesquelético sejam documentadas, estudos com medidas desfecho mais abrangentes e em fases mais tardias da lesão ainda são escassos. Objetivo: Avaliar as adaptações estruturais e físico-funcionais em indivíduos que sofreram fratura unilateral de membro inferior tratadas cirurgicamente. Métodos: Participaram do estudo 32 pacientes de ambos os sexos, com idade entre 18 e 59 anos, com diagnóstico de fratura unilateral de membro inferior e alta hospitalar de no mínimo 1 ano. O membro inferior acometido foi comparado ao membro inferior saudável de todos os participantes utilizando as medidas de desfecho: espessura muscular do vasto lateral (ultrassonografia), força de extensão e flexão do joelho (dinamômetro isocinético), amplitude de movimento de dorsiflexão do tornozelo (teste da distância do pé à parede) e aptidão funcional do membro inferior (teste de salto horizontal simples e triplo). Resultados: Foram encontradas diferenças estatisticamente significativas entre os membros acometidos e não acometidos nas medidas de espessura muscular (p = 0,0001), força de extensão do joelho (p = 0,0094), amplitude de dorsiflexão (p = 0,0004) e desempenho funcional (p = 0,0094, salto simples e p = 0,0114, salto triplo). Em todos os desfechos significativos os valores do membro acometido foram menores que o do membro não acometido. O pico de torque dos músculos flexores do joelho não demonstrou diferença estatisticamente significante entre membros (p = 0,0624). Conclusão: Indivíduos que sofreram fratura unilateral de membro inferior tratado cirurgicamente apresentam alterações estruturais e físico-funcionais tardias importantes em relação ao membro não acometido. Resumen Introducción: La fractura es una lesión traumática sufrida en el hueso que puede ocurrir por diversas causas.

RESUMO Objetivo Verificar a ocorrência e associar a presença dos hábitos orais deletérios com as estruturas e funções do Sistema Estomatognático, quanto aos aspectos de fala, oclusão e respiração, na percepção dos responsáveis. Método Estudo transversal, de caráter exploratório. A amostra, não probabilística, foi composta por 289 crianças de zero a 12 anos atendidas em uma unidade de estratégia de saúde da família. Os dados foram obtidos através de um questionário de identificação de hábitos deletérios aplicado com os responsáveis pelas crianças. Os resultados foram considerados a um nível de significância de 5% e as análises foram realizadas utilizando o programa SPSS versão 19.0 e o teste Quiquadrado de associação para análise das variáveis categóricas. Resultados O índice de aleitamento materno foi de 85%, entretanto, apenas 32,4% foram amamentados exclusivamente até os seis meses. Os hábitos mais prevalentes e mantidos atualmente foram a mamadeira (28,62%) e a chupeta (23,18%) convencional. Houve associação significativa (p=0,001) entre o fato de a criança permanecer com a boca aberta e respirar de modo oral e oronasal. A presença de hábitos como a mamadeira (p=0,016) e a chupeta (p=0,001) ortodôntica estava relacionada ao modo respiratório relatado. O tempo de manutenção dos hábitos estava associado à percepção da presença de alterações na fala (p=0,046); e oclusais (p=0,014). Conclusão A presença e a manutenção de hábitos orais deletérios mostraram-se associadas à percepção da presença de alterações nas estruturas e funções do Sistema Estomatognático de alterações de oclusão, respiração e fala, representando parcela importante da demanda por reabilitação. ABSTRACT Purpose To verify the occurrence and associate the presence and duration of harmful oral habits with the structures and functions of the stomatognathic system. Methods This is a cross-sectional, exploratory study. Participants’ participation was formalized by the signing of an Informed Consent Form. The non-probabilistic sample comprised 289 children aged one to 12 years assisted at a Family Health Strategy unit. The data were obtained through a questionnaire to identify harmful oral habits applied to the children’s parents and/or guardians. The results were considered at 5% level of significance. The statistical analyses were performed using the SPSS 19.0 software and the chi-squared association test was employed to investigate the categorical variables. Results The breastfeeding rate found was 85%; however, only 32.4% of the children were exclusively breastfed until six months of age. The most prevalent habits and those currently maintained were use of conventional bottle (28.62%) and conventional pacifier (23.18%). Significant correlation (p=0.001) was found between keeping the mouth open and oral and oronasal breathing. The presence of habits such as using orthodontic bottle (p=0.016) and orthodontic pacifier (p=0.001) was associated with the breathing mode reported. Habit duration was associated with the perception of changes in speech (p=0.046) and with malocclusion (p=0.014). Conclusion The presence and duration of harmful oral habits were associated with the perception of changes in the structures and functions of the stomatognathic system regarding occlusion, breathing, and speech, accounting for a significant portion of the demand for rehabilitation.

The bone is one of the relevant target organs of heavy metals, and heavy metal toxicity is associated with several degenerative processes, such osteoporosis and bone mineral alterations, that could lead to fractures. We aimed to study a presumed relationship between bone density, evaluated by quantitative bone ultrasound (QUS), dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) and the dietary intake of cadmium, lead and mercury in healthy premenopausal women. A total of 158 healthy, non-smoking, premenopausal women were incorporated into the study. A validated food frequency questionnaire (FFQ) was administered to assess intake during the preceding seven days. The median predicted dietary cadmium intake among the 158 women studied was 25.29 μg/day (18.62–35.00) and 2.74 μg/kg body weight/week (b.w./w) (1.92–3.83). Dietary lead intake was 43.85 μg/day (35.09–51.45) and 4.82 μg/kg b.w./w (3.67–6.13). The observed dietary mercury intake was 9.55 μg/day (7.18–13.57) and 1.02 μg/kg b.w./w (0.71–1.48). Comparisons, in terms of heavy metal intake, showed no significant results after further adjusting for energy intake. No statistically significant correlations between heavy metal intake and the QUS, DXA and pQCT parameters were observed. Levels of dietary exposure of cadmium, lead and mercury were mostly within the recommendations. We did not find associations between the QUS, DXA and pQCT parameters and the dietary intake of the studied heavy metals in healthy premenopausal women.

Background: Deep dry needling (DDN) and ischemic compression technic (ICT) may be considered as interventions used for the treatment of Myofascial Pain Syndrome (MPS) in latent myofascial trigger points (MTrPs). The immediate effectiveness of both DDN and ICT on pressure pain threshold (PPT) and skin temperature of the latent MTrPs of the triceps surae has not yet been determined, especially in athletes due to their treatment requirements during training and competition. Objective: To compare the immediate efficacy between DDN and ICT in the latent MTrPs of triathletes considering PPT and thermography measurements. Method: A total sample of 34 triathletes was divided into two groups: DDN and ICT. The triathletes only received a treatment session of DDN (n = 17) or ICT (n = 17). PPT and skin temperature of the selected latent MTrPs were assessed before and after treatment. Results: Statistically significant differences between both groups were shown after treatment, showing a PPT reduction (p &lt, 0.05) in the DDN group, while PPT values were maintained in the ICT group. There were not statistically significant differences (p &gt, 0.05) for thermographic values before and treatment for both interventions. Conclusions: Findings of this study suggested that ICT could be more advisable than DDN regarding latent MTrPs local mechanosensitivity immediately after treatment due to the requirements of training and competition in athletes&rsquo, population. Nevertheless, further studies comparing both interventions in the long term should be carried out in this specific population due to the possible influence of delayed onset muscle soreness and muscle damage on PPT and thermography values secondary to the high level of training and competition.

OBJECTIVE: Evaluate the effects of ultrasound and stretching in morphology after rat muscle contusion. METHODS: Male Wistar rats (n = 35, 8-9 weeks, 271 ± 14 g) were divided into five groups: control group (CG = 3); lesion group (LG = 8); lesion + ultrasound group (LUG = 8); lesion + stretching group (LSG = 8); lesion + ultrasound + stretching group (LUSG = 8). The ultrasound was applied in LUG and LUSG from the third to the seventh day, the dose used was 50% pulsed, 0.5 W/cm2, 5 min. From the tenth until the twenty first day, passive stretching was performed, in four repetitions lasting 30 s each with 30 s of rest. Initial and final body weight, muscle weight and length, number and sarcomere length, muscle fiber cross-sectional area, and percentage of collagen were evaluated after 22 days. RESULTS: The final body weight was higher than the initial in all groups. The number of sarcomeres was statistically higher in LSG than LUG and higher in LUSG than LUS and CG; in sarcomere length was higher in LUG when compared with LSG (p < 0.05). The cross sectional area in LG was higher than LSG, and the percentage of collagen was higher in LG when compared with LSG and CG; in LUG when compared with LSG and CG; and in LUSG when compared with CG. CONCLUSION: The passive stretching protocol induced sarcomerogenesis and antifibrotic effect over the muscle submitted to contusion. Ultrasound, even in association with stretching, was not sufficient to prevent fibrosis in the injured muscle. RESUMO OBJETIVO: Avaliar os efeitos do ultrassom terapêutico e/ou alongamento, na morfologia após contusão muscular em ratos. MÉTODOS: Ratos Wistar machos (n = 35, 8-9 semanas, 271 ± 14 g) foram divididos em cinco grupos: Grupo Controle (GC = 3); Grupo Lesão (GL = 8); Grupo Lesão + Ultrassom (GLUS = 8); Grupo Lesão + Alongamento (GLA = 8); Grupo Lesão + Ultrassom + Alongamento (GLUSA = 8). A aplicação do ultrassom no GLUS e GLUSA foi feita do terceiro ao sétimo dia, pulsado 50%, 0,5 W/cm2, 5 min. Do décimo ao vigésimo primeiro dia foi feito o alongamento passivo no GLA e GLUSA, em quatro repetições de 30 s, com 30 s de intervalo, cada repetição. Após 22 dias, os ratos foram pesados e os músculos de ambas as patas foram retirados para análise do peso e comprimento muscular, número e comprimento dos sarcômeros, área de secção transversa e porcentagem de colágeno. RESULTADOS: O peso corporal final foi maior do que o inicial em todos os grupos. O número de sarcômeros foi maior no GLA em relação ao GLUS e no GLUSA em relação ao GLUS e ao GC; o comprimento dos sarcômeros foi maior no GLUS comparado com o GLA (p < 0,05). A área de secção transversa no GL foi maior do que no GLA e a porcentagem de colágeno foi maior no GL comparado com o GLA e o GC; no GLUS com o GLA e o GC; no GLUSA com o GC. CONCLUSÃO: O protocolo de alongamento passivo induziu a sarcomerogênese e apresentou efeito antifibrótico em músculos submetidos a contusão. O ultrassom, independentemente da associação com o alongamento, não foi suficiente para impedir a fibrose nos músculos lesados.

The aim of this study was to analyze the effects of short-term resistance training on the body composition profile and muscle function in a group of Anorexia Nervosa restricting type (AN-R) patients.The sample consisted of AN-R female adolescents (12.8 ± 0.6 years) allocated into the control and intervention groups (n = 18 each). Body composition and relative strength were assessed at baseline, after 8 weeks and 4 weeks following the intervention.Body mass index (BMI) increased throughout the study (p = 0.011). Significant skeletal muscle mass (SMM) gains were found in the intervention group (p = 0.045, d = 0.6) that correlated to the change in BMI (r = 0.51, p 0.031). Meanwhile, fat mass (FM) gains were significant in the control group (p = 0.047, d = 0.6) and correlated (r 0.60) with change in BMI in both the groups. Significant relative strength increases (p 0.001) were found in the intervention group and were sustained over time.SMM gain is linked to an increased relative strength when resistance training is prescribed. Although FM, relative body fat (%BF), BMI and body weight (BW) are used to monitor nutritional progress. Based on our results, we suggest to monitor SMM and relative strength ratios for a better estimation of body composition profile and muscle function recovery. Implications for Rehabilitation Anorexia Nervosa Restricting Type (AN-R) AN-R is a psychiatric disorder that has a major impact on muscle mass content and function. However, little or no attention has been paid to muscle recovery. High intensity resistance training is safe for AN-R after hospitalization and enhances the force generating capacity as well as muscle mass gains. Skeletal muscle mass content and muscular function improvements are partially maintained for a short period of time when the exercise program ceases.

Background: Heavy metals, such as lead, cadmium, and mercury, are absorbed through contaminated food sources and water. Few studies have investigated the extent to which dietary heavy metals are associated with low bone mineral density. Aims: We aimed to characterize the dietary intake of the heavy metals lead, cadmium and mercury among healthy, non-smoking postmenopausal women in Spain. Furthermore, we sought to establish a putative relationship between bone health and the intake of these heavy metals in this population. Study Design: The daily intake of the heavy metals considered for the different food groups was calculated by accounting for food content and consumption in 281 postmenopausal women. Bone measurements were performed using a Quantitative Bone Ultrasound (QUS), a Dual-Energy X-ray Absorptiometry (DXA) and a Peripheral Quantitative Computed Tomography (pQCT). Results: The average estimated dietary cadmium exposure among the 281 women studied was 29.87 µg/day (20.41–41.04) and 3.03 µg/kg body weight (b.w.; 2.17–4.40). Dietary lead exposure was 46.24 µg/day (38.11–54.77) and 4.87 µg/kg b.w. (4.00–6.14). The estimated dietary mercury exposure was 11.64 µg/day and 1.19 µg/kg b.w. (0.82–1.76). Participants were classified according to their heavy metal intake (above or below the respective medians). After further adjustment for potential confounding factors, no significant differences were found in all the measured parameters (p > 0.05). Conclusions: We did not find associations between bone health and the dietary intake of three heavy metals in postmenopausal women. Dietary intake of the measured heavy metals were within the recommended valuesofilms.

RESUMO Introdução: As lesões esportivas são desordens que têm grande impacto no desempenho do atleta. Objetivo: Desenvolver e validar um questionário de pré-participação em esportes que identifique atletas com fatores de risco ou probabilidade de lesão musculoesquelética, a fim de selecioná-los para avaliação médica especializada. Métodos: Utilizou-se a técnica Delphi, que consiste em reunir informações e chegar a um consenso de especialistas sobre um tema não encontrado na literatura pertinente. A versão inicial do questionário de prontidão para o esporte com foco nas lesões musculoesqueléticas (MIR-Q) foi embasada na experiência do pesquisador nas áreas de ortopedia/traumatologia esportiva e medicina do exercício e do esporte (MEE) e amparada por referenciais teóricos. Resultados: Na fase piloto realizou-se a análise de conteúdo do MIR-Q com avaliação de nove especialistas em MEE. Das sete questões iniciais, houve a retirada da questão cinco. Na primeira rodada da técnica Delphi, 25 especialistas avaliaram as seis questões do MIR-Q. As rodadas de avaliação foram programadas para repetição, caso não se alcançasse o mínimo de concordância de 75% entre as respostas da maioria dos especialistas (mais de 50%) para cada questão, utilizando-se uma escala tipo Likert, com variação de 1 a 5. Na rodada um, três questões foram modificadas, e obteve-se consenso (concordância de 80% a 100%), índice que variou de 75% a 87,5% quanto à reprodutibilidade. A medida da consistência interna do MIR-Q (alfa de Cronbach) foi satisfatória tanto na primeira rodada (0,70) quanto na reprodutibilidade (0,88). Conclusão: Considera-se que o MIR-Q é um instrumento simples e válido, do ponto de vista da validade do conteúdo, para triagem de atletas com possíveis lesões musculoesqueléticas e encaminhamento ao médico especialista. ABSTRACT Introduction: Sports injuries are disorders that have great impact on athletic performance. Objective: To develop and validate a questionnaire of pre-participation in sports that identifies athletes with risk factors or likelihood of musculoskeletal injury in order to select them for specialized medical evaluation. Methods: We used the Delphi Technique to gather information and reach a consensus of experts on a topic, which is not found in the related literature. The initial version of the Sport Readiness Questionnaire (MIR-Q) focusing on musculoskeletal injuries was based on the researcher's experience in the areas of sports orthopedics/traumatology and medicine of exercise and sport (MES) and was supported by theoretical references. Results: In the pilot phase, the analysis of the MIR-Q content was performed by nine specialists in MES. Of the seven initial questions, the question 5 was removed. In the first round of the Delphi Technique, 25 experts evaluated the six questions of the MIR-Q. The rounds were programmed to be repeated until the minimum agreement of 75% was reached among the responses of the majority of specialists (over 50%) for each question, through a Likert-type scale ranging from 1 to 5. In the round one, three questions were modified and consensus was reached (concordance of 80% to 100%), an index that varied from 75% to 87.5% as for reproducibility. The measure of the internal consistency of MIR-Q (Cronbach's alpha) was satisfactory both in the first round (0.70) and reproducibility phase (0.88). Conclusion: The present questionnaire proved to be a simple and valid tool from the point of view of content validity for screening athletes with probability of musculoskeletal injuries for referral to specialists.

SUMMARY BACKGROUND: To present data on the social security burden of diseases of the musculoskeletal system and connective tissue (DSOTC) in Brasil in 2014, and evolution of these social security expenditures between 2009 and 2014. METHOD: Compilation and analysis of data on the granting of disability pensions and sickness benefits in the year 2014, available on the official website of Social Security, classified according to ICD 10. It was evaluated the evolution between 2009 and 2014, using the F test to compare the curves with the growth of the active age population (PIA). RESULTS: Among the 22 disease groups classified according to ICD-10, the DSOTC group led benefits grants in 2014, with 19% of the sickness benefits and 13.5% of the disability pensions. The main causes of sickness benefit and disability retirement were, respectively: dorsopathies (43.3% and 41.2%), soft tissue diseases (27.3% and 19.7%), osteoarthritis (7.6% % And 27.8%) and chronic inflammatory arthropathies (2.8% and 7.9%). In the evolution of the number of sickness benefits granted between 2009 and 2014, both INSS and DSOTC totals showed an increasing tendency (35.9 and 35.3%, respectively, with p = 0.000 for both). As for disability retirement, there was a 5.9% increase in the INSS total (p = 0.039), while for the DSOTC there was a decrease of 7.6% (p = 0.005). CONCLUSIONS: These data point to a progressive increase in the granting of sickness pensions and disability benefits in the country, superior to the growth of the PIA, as well as a high participation of DSOTC in these benefits. RESUMO OBJETIVOS: Apresentar dados sobre o ônus previdenciário das doenças do sistema osteomuscular e tecido conjuntivo (DSOTC) no Brasil no ano de 2014, e sua evolução entre 2009 e 2014. MÉTODO: Compilação e análise de dados sobre a concessão de aposentadorias por invalidez e auxílios-doença no ano de 2014 disponíveis no portal oficial da Previdência Social, classificados segundo o CID 10. Avaliação da evolução entre 2009 e 2014, utilizando-se o teste F para comparar as curvas com o crescimento da população em idade ativa (PIA). RESULTADOS: Entre 22 grupos de doenças classificados de acordo com o CID 10, o das DSOTC liderou as concessões de benefícios em 2014, com 19% dos auxílios-doença e 13,5% das aposentadorias por invalidez. As principais causas de concessão de auxílio-doença e aposentadoria por invalidez foram, respectivamente: dorsopatias (43,3% e 41,2%), doenças de partes moles (27,3% e 19,7%), osteoartrite (7,6% e 27,8%) e artropatias inflamatórias crônicas (2,8% e 7,9%). Na evolução do número de auxílios-doença concedidos entre 2009 e 2014, tanto o total do INSS quanto o do grupo DSOTC apresentaram tendência crescente (35,9 e 35,3%, respectivamente, com p = 0,000 para ambos). Já para aposentadoria por invalidez, houve aumento de 5,9% no total do INSS (p = 0,039), enquanto que para as DSOTC houve um decréscimo de 7,6% (p = 0,005). CONCLUSÕES: Verificou-se uma elevação progressiva na concessão de auxílio-doença e aposentadoria por invalidez no País, superior ao aumento da população em idade ativa. As DSOTC foram o grupo com maior participação relativa nesses benefícios.

RESUMO Objetivo Estabelecer ponto de corte entre as variáveis clínicas e funcionais para avaliar a prevalência de sarcopenia e dinapenia em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC), além de analisar o impacto da Disfunção Muscular Esquelética (DME) nestas variáveis. Métodos Realizado estudo transversal com pacientes diagnosticados com DPOC para determinar sarcopenia ou dinapenia por meio do índice de baixa massa muscular e Força de Preensão Palmar (FPP). Avaliadas a função pulmonar, força muscular respiratória e capacidade funcional (CF). A precisão das variáveis na determinação dos pontos de corte previstos para as doenças em questão foi obtida a partir da curva Receiver Operating Characteristic (ROC) e de uma análise bidirecional da variância. Resultados Ao final da análise, obtiveram-se 20 pacientes com DPOC estratificados por sarcopenia (n = 11) e dinapenia (n = 07). O grupo com sarcopenia apresentou menor massa magra e menor pressão inspiratória máxima (PImáx), diminuição da Força de Preensão Palmar (FPP) e redução da CF (p
