ABSTRACT

Abstract Introduction The smartphone, a popular mobile device, has become attractive because it is easy to use and due to it multifunctionality. Its prolonged use, with anterior flexion of the neck and repetitive movements of the upper limbs, contributes to musculoskeletal symptoms. Objective To evaluate changes in cervical posture due to smartphone use in adults, as well as verify the association of posture with health-related factors. Methods Cross-sectional study, carried out at two universities in Fortaleza, Ceará, Brasil, between 2018 and 2019. A total of 769 adults (>18 years old) who routinely used smartphones participated. Data on socioeconomic variables, health conditions and smartphone use were collected. The cervical postural alignment was assessed, with the vertical head alignment (VHA) being measured using photogrammetry, in the anatomical position (baseline) and while typing on the smartphone. Results The mean age was 23 years (± 6.7), with a higher proportion of females (72.1%; n = 559) and an average of 7.9h (± 4.4) using the device. Smartphone use led to the forward head movement related to males (p < 0.05 by ΔVHA), time spent using the device (p < 0.05 by ΔVHA), functional disability in the cervical region (p < 0.05 by ΔVHA) and not sleeping well (p = 0.019 by ΔVHA on the R side). Conclusion Using a smartphone in the typing position causes the head to tilt forward, being related to longer usage time, male gender, cervical region dysfunction and sleep.

ABSTRACT

ABSTRACT - This study aimed to evaluate the relation between the postural pattern according to the Godelieve Denys-Struyf (GDS) method with postpartum depression and pain in immediate postpartum women. A cross-sectional study was conducted, including 29 women at 1-3 postpartum days. The Edinburgh Postnatal Depression Scale (EPDS) assessed depression and Visual Numerical Scale assessed pain score (from 0=no pain to 10=the most intense pain). Postural pattern was categorized into groups according to the deviation plane: axial (anteromedial, posteromedial, anteroposterior, and posteroanterior postures) and relational (anterolateral and posterolateral postures) or mixed, considering upper and lower limbs. Participants' age ranged from 19 to 41 years, body mass index from 21.4 to 43.8 kg/m 2 . The EPDS scored from 10 to 26 points. In total, 52% women reported pain, but the pain score was similar among postural pattern groups (p=0.77) and not correlated with EPDS (p=0.88). Women's postural patterns were: mixed (45%), relational (38%), and axial (17%). EPDS score was higher for relational pattern group than axial group (20.45±1.63 vs 15.00±3.24; p=0.01). In conclusion, the mixed postural pattern was the most frequent. The relational postural pattern group (anterolateral and posterolateral posture) presented a higher depression score than the axial postural pattern group. No association was found between postural patterns and the pain score or between pain and postpartum depression.


RESUMEN - El objetivo de este estudio fue evaluar la relación entre el patrón postural según el método Godelieve Denys-Struyf (GDS), la depresión postparto y el dolor en mujeres en el puerperio inmediato. Se realizó un estudio transversal con 29 mujeres en el período entre 1 y 3 días después del parto. Se evaluaron la depresión mediante la Escala de Depresión Postparto de Edimburgo (EPDS) y el dolor mediante la Escala Numérica Visual del Dolor (0=ningún dolor, 10=dolor intenso). El patrón postural se categorizó según el plano de la alteración postural: axial (planos anteromedial, posteromedial, anteroposterior y posteroanterior), relacional (planos anterolateral y posterolateral) o mixto considerando tanto las extremidades superiores como las inferiores. Los resultados mostraron que las mujeres, de entre 19 y 41 años de edad, tenían un índice de masa corporal entre 21,4 y 43,8 kg/m2. La puntuación de la EPDS osciló entre 10 y 26 puntos. El 52% de las mujeres declararon sentir dolor, pero la puntuación en la escala de dolor fue similar en los tres grupos de patrones posturales (p=0,77) y no hubo correlación con la puntuación de la EPDS (p=0,88). Los patrones posturales presentados fueron mixto (45%), relacional (38%) y axial (17%). La puntuación de la EPDS fue mayor en el grupo de patrón postural relacional en comparación con el axial (20,45±1,63 vs. 15,00±3,24; p=0,01). Se concluye que el patrón postural mixto fue el más frecuente entre las mujeres. El grupo con un patrón postural relacional (planos anterolateral y posterolateral) obtuvo mayores tasas en la EPDS que el axial. No hubo asociación entre el patrón postural y la puntuación en la escala de dolor ni entre el dolor y la depresión.


RESUMO - O objetivo deste estudo foi avaliar a relação entre o padrão postural, de acordo com o método Godelieve Denys-Struyf (GDS), a depressão pós-parto e a dor em mulheres no puerpério imediato. Foi realizado um estudo transversal com 29 mulheres no período de 1 a 3 dias após o parto. A depressão foi avaliada por meio da Escala de Depressão Pós-parto de Edimburgo (EPDS) e a dor pela Escala Visual Numérica de dor (0=ausência de dor, 10=pior dor possível). O padrão postural foi categorizado de acordo com o plano do desvio da postura: axial (posturas ântero-medial, póstero-medial, ântero-posterior e póstero-anterior), relacional (posturas ântero-lateral e póstero-lateral) ou misto, considerando membros superiores e inferiores. Como resultados, as mulheres, entre 19 e 41 anos de idade, apresentaram índice de massa corporal entre 21,4 e 43,8 kg/m 2 . A pontuação na EPDS variou de 10 a 26 pontos. 52% das mulheres relataram sentir dor, porém a pontuação na escala de dor foi similar nos três grupos de padrão postural (p=0,77) e não houve correlação com a pontuação na EPDS (p=0,88). Os padrões posturais apresentados foram: misto (45%), relacional (38%) e axial (17%). A pontuação da EPDS foi maior para o grupo de padrão postural relacional, em comparação com o axial (20,45±1,63 vs 15,00±3,24; p=0,01). Como conclusão, o padrão postural misto foi o mais frequente entre as mulheres. O grupo com padrão postural relacional (posturas ântero-lateral e póstero-lateral) apresentou maior pontuação na EPDS que o axial. Não houve associação entre o padrão postural e a pontuação na escala de dor ou entre a dor e a depressão.

ABSTRACT

ABSTRACT Objective: To evaluate smartphone addiction and postural alterations in the cervical region in adolescents. Methods: A cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages. In the first, they answered four self-administered questionnaires: sociodemographic questionnaire, health conditions and smartphone use, Nordic Musculoskeletal Symptom Questionnaire (NMQ), Self-Report Questionnaire (SRQ-20) and the Smartphone Addiction Inventory (SPAI-BR). In the second stage, they were submitted to photogrammetry using the Postural Assessment Software (SAPO) and anthropometric assessment (weight and height). The software SPSS Statistics version 23.0 was used for data analysis. Results: Of the total number of adolescents, 63.3% (n=178) showed smartphone addiction, using it for 5.8 hours (±3.5) during the week and 8.7 (±4.0) hours on the weekend. When analyzing postural alignment in the anterior view, a significant reduction in the lateral head tilt was observed when typing on the smartphone (p=0.002) compared to the anatomical position (baseline). In the lateral view, an increase in head anteriorization was observed during smartphone use (p<0.05). There was an association between smartphone addiction and head anteriorization (p<0.05). Conclusions: The use of the smartphone in the typing position causes postural alterations in the cervical region, especially in adolescents with smartphone addiction. Therefore, health promotion measures that alert adolescents to the adverse effects caused by prolonged smartphone use are necessary.


RESUMO Objetivo: Avaliar a dependência do smartphone e a alteração postural da região cervical em adolescentes. Métodos: Estudo transversal, com 281 adolescentes (15 a 19 anos), que frequentavam da 1ᵃ à 3ᵃ série do ensino médio, realizado entre setembro e outubro de 2019 na cidade de Fortaleza, Ceará, Brasil. A coleta dos dados ocorreu em duas etapas. Na primeira, eles responderam a quatro questionários autoaplicáveis: questionário sociodemográfico, condições de saúde e uso do smartphon e, Questionário Nórdico de Sintomas Musculoesqueléticos (NMQ), Self-Report Questi onnaire (SRQ-20) e o Smartphone A ddiction Inventory (SPAI-BR). Na segunda etapa, foram submetidos a fotogrametria pelo Software de Avaliação Postural (SAPO) e avaliação antropométrica (peso e altura). Para a análise dos dados, foi utilizado o SPSS Statistics versão 23.0. Resultados: Do total, 63,3% (n=178) dos adolescentes apresentaram dependência do smartphone, com o uso de 5,8 horas (±3,5) durante a semana e 8,7 (±4,0) no fim de semana. Ao analisar o alinhamento postural na visão anterior, observou-se redução significativa da inclinação lateral de cabeça ao digitar no smartphon e (p=0,002) comparado à posição anatômica (baseline). Na visão lateral foi constatado aumento da anteriorização de cabeça durante o uso do smartphon e (p<0,05). Houve associação da dependência do smartphone com a anteriorização de cabeça (p<0,05). Conclusões: O uso do smartphone na posição de digitação causa alteração postural na região cervical, destacadamente naqueles que apresentam dependência do dispositivo. Dessa forma, são necessárias medidas de promoção de saúde que alertem os adolescentes sobre os efeitos adversos causados pelo uso prolongado do smartphone.

ABSTRACT

ABSTRACT Objective: Evaluate and correlate the sagittal balance parameters with the postural of the pelvis and lumbar spine. Methods: 80 individuals of both sexes, aged between 20 and 35 years, were evaluated. Biophotogrammetry was done with the SAPO software program. Measurements of the sagittal balance parameters were obtained by analyzing a lateral view panoramic radiography of the vertebral column, in which the anatomical points of reference were digitally marked. The calculation of the angles was done automatically by the Keops program. Results: In Keops assessment, 17.5% of the sample had high pelvic incidence angles (> 60°), 31.5% had low pelvic incidence angles (< 45°), and 51.2% had medium pelvic incidence angles (between 46° and 59°). SAPO showed 12,5% lordosis, 40% retroversion, and 47,5% normal curvature. In the right lateral view, pelvic incidence angle had a moderate and positive correlation with vertical alignment of the trunk and with vertical alignment of the body, and a negative and moderate correlation with horizontal alignment of the pelvis. Conclusion: Differences were found between vertical alignment measurements from the postural evaluation system (SAPO). A positive correlation was found between PI from Keops and pelvic anteversion from SAPO. Level of Evidence II; Prospective Study.

ABSTRACT

La postura corporal es el resultado de la compleja interacción del sistema músculo-esquelético y nervioso que permite al cuerpo mantenerse en una posición adecuada, con un balance ergonómico y un gasto de energía mínimo. Las exigencias técnicas y el perfil morfofuncional del polista se complementan como factores internos predisponentes a lesiones por sobreuso. El objetivo del estudio consistió en analizar el perfil postural en jugadores élite de polo acuático. Se diseñó un estudio descriptivo, prospectivo y transversal. Los métodos científicos seleccionados estuvieron en el nivel teórico, empírico y estadístico-matemático. Se evaluaron 18 polistas masculinos, de élite, de 18 a 33 años de edad. En el plano frontal, el perfil predominante fue cabeza centrada (13; 72,2 %), con hombro izquierdo más alto (14; 77,8 %), espina iliaca anterosuperior homolateral más alta (10; 55,6 %), triángulo torácico derecho más grande que el izquierdo (10; 55,6%) y ambas rodillas con correcta alineación frontal (10; 55,6 %). En el plano sagital la cabeza se observó adelantada (18; 100 %), pelvis neutra (14; 77,78 %), ambas rodillas en recurvatum (10; 55,6 %) e inclinación corporal anterior (18; 100 %) con un rango de angulación de 2-6 grados. En el plano frontal posterior la cabeza se encontró neutra (14; 77,78 %) con inclinación corporal izquierda (12; 66,67 %). La evaluación del perfil de postura en polistas es útil para diagnosticar desalineaciones en los segmentos corporales, al generar una herramienta en el control biomédico del entrenamiento deportivo.


A postura corporal é resultado da complexa interação do sistema musculoesquelético e nervoso que permite ao corpo permanecer em uma posição adequada, com equilíbrio ergonômico e mínimo gasto energético. As exigências técnicas e o perfil morfofuncional do jogador de pólo complementam-se como fatores internos predisponentes a lesões por uso excessivo. O objetivo do estudo foi analisar o perfil postural em jogadores de elite de pólo aquático. Foi desenhado um estudo descritivo, prospectivo e transversal. Os métodos científicos selecionados foram de nível teórico, empírico e estatístico-matemático. Foram avaliados 18 jogadores de pólo de elite do sexo masculino, com idades entre 18 e 33 anos. No plano frontal, o perfil predominante foi cabeça centrada (13; 72,2%), com ombro esquerdo mais alto (14; 77,8%), espinha ilíaca ântero-superior ipsilateral mais alta (10; 55,6%), triângulo torácico direito maior que o esquerdo ( 10; 55,6%) e ambos os joelhos com alinhamento frontal correto (10; 55,6%). No plano sagital observou-se cabeça para frente (18; 100%), pelve neutra (14; 77,78%), ambos os joelhos em recurvatum (10; 55,6%) e inclinação anterior do corpo (18; 100%) com amplitude de angulação de 2-6 graus. No plano frontal posterior a cabeça estava neutra (14; 77,78 %) com inclinação do corpo para a esquerda (12; 66,67 %). A avaliação do perfil postural em jogadores de pólo é útil para diagnosticar desalinhamentos em segmentos corporais, gerando uma ferramenta no controle biomédico do treinamento esportivo.


Body posture is the result of the complex interaction of the musculoskeletal and nervous system that allows the body to remain in an adequate position, with ergonomic balance and minimal energy expenditure. The technical demands and the morphofunctional profile of the polo player complement each other as internal factors predisposing to injuries due to overuse. The objective of the study was to analyze the postural profile in elite water polo players. A descriptive, prospective and cross-sectional study was designed. The selected scientific methods were at the theoretical, empirical and statistical-mathematical level. 18 elite male polo players, aged 18 to 33, were evaluated. In the frontal plane, the predominant profile was centered head (13; 72.2 %), with higher left shoulder (14; 77.8 %), higher ipsilateral anterior superior iliac spine (10; 55.6 %), triangle right thoracic larger than the left (10; 55.6 %) and both knees with correct frontal alignment (10; 55.6 %). In the sagittal plane, the head was observed forward (18; 100 %), neutral pelvis (14; 77.78 %), both knees in recurvatum (10; 55.6 %) and anterior body inclination (18; 100 %) with an angulation range of 2-6 degrees. In the posterior frontal plane, the head was neutral (14; 77.78 %) with left body inclination (12; 66.67 %). The evaluation of the posture profile in polo players is useful to diagnose misalignments in body segments, generating a tool in the biomedical control of sports training.

ABSTRACT

Introduction:The talus is a tarsal bone articulated with the tibia, fibula, navicular, and calcaneus bones to form supratalar, pretalar, and subtalar joints, respectively. A squatting facet is a kind of anomaly that forms on the surfaces where the tibia and talus articulate. The squatting facet states the daily activities and living style of society. Squatting is described as the hyperflexion of the hip and the knee and the movement of hyperdorsiflexion between the leg and the ankle. Materials and Methods: In the present cross‑sectional study, 600 dry adult human tali were taken from the osteology laboratory in the Department of Anatomy, King George’s Medical University, UP, Lucknow. Each talus was examined for the presence of various patterns of articular facets on the neck of the talus and extensions of its trochlear surface. Ethical clearance was obtained from the Institutional Ethics Committee, King George’s Medical University, Lucknow, as reference code: 121 ECMIIA/P3. Results: In our study, we observed that the lateral, medial, and combined squatting faces are 282 (47.64%), 49 (8.28%), and 22 (3.72%), respectively. Lateral, medial, and continuous trochlear extensions are 126 (21.12%), 120 (20.58%), and 31 (5.36%), respectively, in the Indian population. Conclusion: Modifications of the neck of the talus (squatting facets and trochlear extensions) are the result of prolonged squatting positions, which is a common habit of the Indian population, and incidences of these variations can be used as an anthropological marker for racial and regional differentiation of unidentified bones.

ABSTRACT

Introduction: Institutionalized young people may exhibit impaired development due to lack of support, correct guidance regarding their physiological changes, and knowledge about postural changes. Methods: This is a longitudinal observational case series study. Adolescents residing in shelters who could understand the entire protocol were invited to participate in the study. Ten meetings were held, once a week, with 8 theoretical-practical interventions and 2 pre and post-PEP evaluations. The evaluations were: static posture, dynamic balance, handgrip strength, self-esteem, quality of life, and a theoretical questionnaire on general knowledge. Results: From 18 adolescents, 11 (7 boys and 4 girls), with an average age of 14.8 (±1.3) years concluded the study. After the PEP intervention, a significant improvement was found in the knee angles (3.56º vs. 2.28º) and hip (-12.03º vs. -4.18º) in its plane lateral. The scores of the theoretical questionnaire were 4.75 vs. 11.63 and the handgrip strength was 22.91 vs. 28.54 kgf and 21.55 vs. 26.82 kgf for the right and left limbs. In the quality of life and self-esteem questionnaires, no statistically significant differences were obtained. Conclusion: PEP imparts benefits to socially vulnerable adolescents for postural angles, handgrip strength and theoretical knowledge. Self-esteem and quality of life did not change, probably due to their high vulnerability.


Introdução: Jovens institucionalizados podem apresentar comprometimento do desenvolvimento por falta de apoio, orientação correta quanto às suas alterações fisiológicas e conhecimento sobre alterações posturais. Métodos: Trata-se de um estudo observacional longitudinal de série de casos. Foram convidados a participar do estudo adolescentes residentes em abrigos que conseguissem compreender todo o protocolo. Foram realizados dez encontros, uma vez por semana, com 8 intervenções teórico-práticas e 2 avaliações pré e pós-PEP. (programa de educação postural). As avaliações foram: postura estática, equilíbrio dinâmico, força de preensão manual, autoestima, qualidade de vida e questionário teórico de conhecimentos gerais. Resultados: Dos 18 adolescentes, 11 (7 meninos e 4 meninas), com idade média de 14,8 (±1,3) anos, concluíram o estudo. Após a intervenção PEP, foi encontrada melhora significativa nos ângulos do joelho (3,56º vs. 2,28º) e quadril (-12,03º vs. -4,18º) no seu plano lateral. As pontuações do questionário teórico foram 4,75 vs. 11,63 e a força de preensão manual foi 22,91 vs. 28,54 kgf e 21,55 vs. 26,82 kgf para os membros direito e esquerdo. Nos questionários de qualidade de vida e autoestima não foram obtidas diferenças estatisticamente significativas. Conclusão: A PEP traz benefícios aos adolescentes em situação de vulnerabilidade social quanto aos ângulos posturais, força de preensão manual e conhecimento teórico. A autoestima e a qualidade de vida não se alteraram, provavelmente devido à sua elevada vulnerabilidade.

ABSTRACT

SUMMARY: The objective of this study was to evaluate the changes of head and cervical spine posture of skeletal class malocclusion in adolescent with maxillary protraction. Thirty cases of skeletal class malocclusion were randomly selected from the Stomatological Hospital of Shanxi Medical University. High-quality lateral cephalograms were collected including pre- and posttreatment to compare the changes of head and cervical spine posture. Data were processed using SPSS 26.0 statistical software. The paired-t test was used to compare pre- and posttreatment mean angular measurements.A significant difference in the SNA(p<0.001), SNB(p<0.01), and ANB(p<0.001) between T1 and T2 showed an improvement in the sagittal relationships. A significant change was observed in middle cervical spine posture, while upper cervical spine posture variables showed no significant difference after treatment. Skeletal class with maxillary protraction appliance not only led to the improvement of sagittal relationship, but also changed the middle cervical spine posture.


El objetivo de este estudio fue evaluar los cambios en la postura de la cabeza y la columna cervical debido a la maloclusión clase esquelética en adolescentes con protracción maxilar. Treinta casos de maloclusión de clase esquelética fueron seleccionados al azar del Hospital Estomatológico de la Universidad Médica de Shanxi. Se recogieron cefalogramas laterales de alta calidad, incluidos el tratamiento previo y posterior, para comparar los cambios en la postura de la cabeza y la columna cervical. Los datos se procesaron con el software estadístico SPSS 26.0. Se utilizó la prueba t pareada para comparar las medidas angulares medias antes y después del tratamiento. Una diferencia significativa en SNA (p <0,001), SNB (p <0,01) y ANB (p <0,001) entre T1 y T2 mostró una mejora en las relaciones sagitales. Se observó un cambio significativo en la postura de la columna cervical media, mientras que las variables de postura de la columna cervical superior no mostraron diferencias significativas después del tratamiento. La clase esquelética con aparato de protracción maxilar no solo condujo a la mejora de la relación sagital, sino que también cambió la postura de la columna cervical media.

ABSTRACT

Introducción: Un apoyo plantar incorrecto puede considerarse un factor etiológico de asimetrías faciales y cráneo-mandibulares pues modifica, de forma instantánea, la relación entre el maxilar y la mandíbula. Por tanto, resulta vital identificar la etiología de estas asimetrías para establecer diagnósticos y tratamientos certeros. Objetivo: Determinar la influencia del apoyo plantar en la postura corporal, la simetría facial y cráneo-mandibular en adolescentes. Métodos: Se realizó un estudio descriptivo y transversal de enero a septiembre de 2019 con 180 adolescentes que asistieron al servicio de Ortodoncia de la Clínica Docente de Especialidades «Victoria de Santa Clara», los cuales cumplían con criterios de selección de la investigación. Se analizaron variables faciales, posturales y cefalométricas. Se determinó: la simetría facial mediante el análisis de líneas faciales, el apoyo plantar al calcular el índice cavitario, la postura corporal, según la prueba de Di Rocca, y la simetría mandibular con el método modificado de Kurt y Uysal. Se siguieron las normas éticas y fueron aplicadas la prueba de Fisher, la de McNemar, y la técnica de conglomerado. Resultados: Predominaron los adolescentes con apoyo plantar asimétrico y los pies varo. Del total de casos con asimetría facial, 72,53 % presentó apoyo plantar asimétrico, y 39,44 % planos biilíaco y biclavicular desequilibrados y divergentes. La asimetría mandibular se observó en el 56,11%, la mayoría con apoyo plantar asimétrico. Conclusiones: Se pudo constatar la influencia del apoyo plantar en la postura corporal, la simetría facial y cráneo-mandibular, pues se observó un alto grado de relación entre las variables estudiadas.


Introduction: an incorrect plantar support can be considered an etiological factor of facial, mandibular and cranial asymmetries since it instantly modifies the relationship between the maxilla and mandible. Therefore, it is vital to identify the etiology of these asymmetries to establish accurate diagnoses and treatments. Objective: to determine the influence of plantar support on body posture and on facial, mandibular and cranial symmetries in adolescents. Methods: a descriptive and cross-sectional study was carried out from January to September 2019 with 180 adolescents who were seen in the Orthodontics service at "Victoria de Santa Clara" Specialty Teaching Dental Clinic, who met the research selection criteria. Facial, postural and cephalometric variables were analyzed. Facial symmetry was determined through the analysis of facial lines, plantar support by means of cavity index, body posture according to the Di Rocca test, and mandibular symmetry with the modified method of Kurt and Uysal. Ethical standards were followed and Fisher's and McNemar's tests as well as clustering technique were applied. Results: adolescents with asymmetric plantar support and varus feet predominated. The 72.53% had asymmetric plantar support from the total cases with facial asymmetry, and 39.44% had unbalanced and divergent biiliac and biclavicular planes. Mandibular asymmetry was observed in 56.11%, mostly with asymmetric plantar support. Conclusions: the influence of plantar support on body posture and on facial, mandibular and cranial symmetries was posible to verify since a high degree of relationship was observed among the variables studied.

ABSTRACT

@#Introduction: Work-related Musculoskeletal disorders (WMSDs) becomes the one of most-occupational problem and highly related to the individual and work factors. Eighty percent (80%) workers in the woven bamboo industry in Mojorejo Village dominated by middle aged workers (>40 years) that most of their producing activities are manually handled, without using machine or modern technology. Incompatibility work station, long working hours and repeated movement aggravated the WMSDs risk. This study aims to describe the WMSDs risk and determine its factors based on individual characteristics. Methods: There are 58 workers as respondents in this cross-sectional study. Data were collected and analyzed using quantitative method. Posture Exposure (PE) were measured using the QEC instrument. While the WMSDs risk were measured using PLIBEL. Individual factors (PE, Age, Working Period) related to WMSDs were analyzed using Multinomial Logistic Regression (95% CI). The Chi-square test were also used to compare PE rates among WMSDs risk levels. Results: Most respondents (48.3%) with 51-70% PE rate have a high level of WMSDs risk. While 27 % respondents with PE rate >70% have a very high level. The neck is the region most exposed to the WMSDs (score 15.5/very high level risk). PE rate is the only factor that significantly related to WMSDs risk (sig. = 0.043; Rsquare = 0.529; r =0.703). While the age and working period has no significant correlation (Sig = 0.859 and 0.851 respectively). Conclusion: Based on the result, immediate improvement required to be implemented. It is suggested to redesigned work stations adjusted to the workers posture and position.

ABSTRACT

Objective:To observe the clinical effectiveness of manual therapy based on posture decoding for patients with lower crossed syndrome (LCS).Methods:Thirty-six LCS patients were randomly divided into an observation group and a control group, each of 18. The observation group received manual therapy based on posture decoding, while the control group was treated with proprioceptive neuromuscular facilitation (PNF), both in 20min sessions, once a week for 4 weeks. Before the experiment, after one, two and four weeks of treatment and followed-up 4 and 8 weeks later, both groups were evaluated using a visual analogue scale (VAS), the Oswestry Disability Index (ODI) and finger-floor distance (FFD). Anterior pelvic tilt angles (ASIS-PSISs), sacral slopes (SS), lumbar curve index (LCI) and surface EMG flexion-relaxation ratios (FRRs) were also recorded from both groups before and after the treatment.Results:After one and four weeks of the treatment, the average VAS, ODI, and FFD had decreased significantly in both groups, with all significantly lower in the observation group, on average. At the final follow-up, the average VAS and ODI scores of both groups were significantly lower than before the treatment, with those of the observation group significantly lower than the control group′s averages. After 4 weeks of treatment significant differences were observed also in the group′s average ASIS-PSISs, SSs and LCIs compared with before the treatment. And right after the treatment the left and right surface electromyography FRRs of the observation group were significantly higher than those of the control group.Conclusion:Manual therapy based on posture decoding can significantly improve the pelvis forward angle and lumbar motion of LCS patients, relieving back pain and relaxing back muscles.

ABSTRACT

Objective:To observe any dependence of anticipatory postural adjustment (APA) on the difficulty of fine upper limb tasks and to document any effect of reticulospinal tract (RST) facilitation on APAs during such tasks.Methods:The study′s bivariate mixed design involved 4 different tasks and 3 different priming states. Thirteen healthy, male, right-handed subjects were recruited. They were asked to complete the 4 tasks of reaching, grasping a cup, pinching a card using the thumb or using the little finger, respectively for 10 times 1 in response to two different starting cues delivered through an earphone. Half of the trials with each task were initiated with 114dB white noise to startle and activate the reticulospinal tract (RST), while the others were activated with 80dB beeps as a control. Electromyographic signals were recorded from the bilateral sternocleidomastoid (SCM), lower trapezius (LT), latissimus dorsi (LD), lumbar erector spinae and right anterior deltoid muscles and also from the right flexor and extensor carpi radialis muscles (ECR/FCR). In the subsequent processing the electromyographic time domain and frequency domain indicators were converted into a pre-motor reaction time, a time to muscle peak contraction, an activation latency, and APA or compensatory postural adjustment (CPA) amplitude of the tested muscles. These were compared among the different tasks and stimuli. In addition, the 114dB test tasks were classified as two different priming status as SCM + and SCM - according to whether the sternocleidomastoid muscle (SCM) was activated in advance. Results:After RST activation the pre-motor reaction time and the time to peak contraction of all of the muscles were significantly shortened in all of the tasks. The deltoid muscle reaction times in the SCM + , SCM - and control states were (106.89±43.78)ms, (136.78±48.74)ms and (168.60±73.17)ms, respectively, and those differences are significant. The APA amplitudes of the contralateral LT and ipsilateral LD were significantly greater than normal, but the timing of muscle activation onset and the APA/CPA amplitudes of the ECR/FCR were not affected. The latency in the anticipatory muscle activation of the ECR in the little finger grip task was significantly shorter than that in reaching. Conclusions:The extensor carpi radialis show task-specific early activation in fine tasks of the upper limbs with different difficulties. RST activation can lead to early starting of expected actions, accelerate muscle contraction and increase APA amplitude of some trunk muscles, but it has no significant effect on APA/CPA amplitudes in the forearm muscles.

ABSTRACT

Objective:To explore the clinical effects of a series of posture intervention strategies on correcting abnormal fetal position, so as to provide a basis for Clinical position management and promotion of natural delivery.Methods:This study was a randomized controlled trial. The convenience sampling method was used to select 196 full-term primiparas women with abnormal fetal orientation confirmed by ultrasound as single fetal head position in the Women′s Hospital, School of Medicine, Zhejiang University from March to October 2022 as the research objects. They were divided into control group 106 cases and research group 90 cases by random number table method. The control group received normal nursing and chose comfortable position by themselves during labor. The research group received a series of ultrasound-guided postural intervention strategies for postural management in the first and second stages of labor on the basis of normal nursing. The angle of progression and the midline angle, the fetal orientation, fetal orientation during complete uterine orifice and delivery outcome were compared between the two groups.Results:Finally, 190 cases were included, 105 cases in the control group and 85 cases in the research group. There were 76 vaginal deliveries in the research group and 95 in the control group. The rate of anterior occipital position and the angle of fetal head rotation in the research group were 73.68% (56/76) and 64.55 (37.90, 85.55)°, which were higher than 45.26% (43/95) and 33.00 (14.00, 60.00)° in the control group;the midline angle of the research group was 57.10(38.50, 75.80)°, which was lower than 80.00 (52.50, 90.30)° of the control group. There was significant difference between the two groups ( χ2 = 14.14, Z = 4.17, - 3.74, all P<0.01). The first stage of labor was 522.50 (413.00, 695.00) minutes and the total stage of labor was 611.00 (488.00, 812.00) minutes in the research group, which was lower than 620.00 (450.00, 795.00) and 700.00 (539.00, 904.00) minutes in the control group ( Z = - 2.34, - 2.03, both P<0.05). Conclusions:The application of the serial position intervention strategy under the ultrasound guidance during the labor process can improve the abnormal fetal position, shorten the first stage of labor time effectively and safely, while it does not have any significant effect on the improvement of the delivery outcome.

ABSTRACT

In view of the high incidence of malignant diseases such as malignant arrhythmias in the elderly population, accidental injuries such as falls, and the problem of no witnesses when danger occurs, the study developed a human vital signs and body posture monitoring and positioning alarm system. Through the collection and analysis of electrocardiogram (ECG), respiration (RESP) and acceleration (ACC) signals, the system monitors human vital signs and body posture in real time, automatically judges critical states such as malignant arrhythmias and accidental falls on the local device side, and then issues alarm information, opens the positioning function, and uploads physiological information and patient location information through 4G communication. Experiments have shown that the system can accurately determine the occurrence of ventricular fibrillation and falls, and issue position and alarm information.

ABSTRACT

Recently, poor posture (hyperkyphosis) has become a problem among children. This study investigated the effectiveness of an intervention (a spine mat) by measuring spinal alignment before and after the intervention in elementary school students. The study included 83 elementary school students. For the intervention, each participant was placed in a supine position on a bed and a spine mat was inserted ensuring that it adhered to the thoracic spine. The primary outcome variables included the thoracic kyphosis angle (TKA), upper thoracic angle, lower thoracic angle, lumbar lordosis angle (LLA), and sacral anteversion angle (SAA) measured in the standing and sitting positions using Spinal Mouse® before and after the intervention. Based on this evaluation, we assigned the participants to two groups: hyperkyphosis (n=25) and non-hyperkyphosis (n=58). Significant differences were observed between the pre-test and post-test TKA in the hyperkyphosis group in the standing position (pre-test: 45.3±4.5° and post-test: 40.8±9.0°, P<0.05). In the non-hyperkyphosis group, significant differences were observed between the pre-test and post-test LLA and SAA in the standing position. However, no significant difference was observed between the pre-test and post-test spinal alignment in the sitting position in both groups. The results of this study indicated that using a spine mat in elementary school children resulted in decreased TKA in the standing position only in the hyperkyphosis group, which exhibited a TKA of 40° or more after the intervention.

ABSTRACT

Background Prolonged awkward postures during occupational activities can lead to excessive musculoskeletal load on the wrist of workers and symptoms such as wrist pain or discomfort. Objective To survey the prevalence of wrist pain among workers in 10 key industries and analyze its correlation with wrist working postures. Methods By using stratified cluster sampling method, workers from 10 key industries, such as footwear manufacturing industry, shipbuilding manufacturing industry, and automobile manufacturing industry, were selected from seven regions in North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China. The demographic information, wrist working postures, pain in wrist of the workers were collected through a cross-sectional survey. Pearson χ2 test was used to compare prevalence by selected factors, trend χ2 test for between group comparison, and unconditional logistic regression models for the association of wrist working postures with wrist pain. Results There were 64052 workers enrolled in this survey, and 56286 provided valid questionnaires (the effective rate was 87.8%). According to the survey, the prevalence of wrist pain was 23.3% (13112/56286), and the industries with higher prevalences were footwear manufacturing (27.1%, 1927/7106), automobile manufacturing (24.9%, 5378/21560), and shipbuilding and related equipment manufacturing (24.4%, 850/3488) industries. Finger pinching (OR=2.09, 95%CI: 1.95-2.24), frequent wrist bending (OR=2.03, 95%CI: 1.92-2.15), fixed wrist bending (OR=1.77, 95%CI: 1.69-1.85), wrist on hard edge (OR=1.34, 95%CI: 1.28-1.40), and arms over shoulders (OR=1.11, 95%CI: 1.05-1.17) increased the risk of reporting wrist pain. Conclusion Awkward postures are related to wrist pain among workers in selected 10 key industries. The related factors are wrist on hard edge, frequent wrist bending, finger pinching, fixed wrist bending, and arms over shoulders.

ABSTRACT

Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.

ABSTRACT

Background Furniture manufacturing is one of the typical labor-intensive industries, and workers in this industry face a high risk of work-related musculoskeletal disorders (WMSDs), which seriously affect the physical and mental health of workers. Objective To explore the prevalence and potential risk factors of WMSDs among workers in a large-scale furniture manufacturing factory. Methods A cross-sectional study of 3431 workers in a furniture factory in Guangdong Province was conducted from September to December 2019. Information including reported WMSDs in various body parts in the past year, demographic characteristics, work organization factors, job characteristics, and work postures was collected by an electronic version of Musculoskeletal Disorders Questionnaire. Pearson χ2 test and binary logistic regression were used to analyze the risk factors leading to WMSDs. Results The overall prevalence rate of WMSDs was 32.12% (1102/3431). The most common WMSDs symptoms occurred in the neck (16.85%), followed by the feet (15.27%), shoulders (14.81%), and hands (14.25%). The prevalence rates of WMSDs in the neck, shoulders, elbows, hands, legs, and feet were significantly different among different types of work (P<0.05). The results of multiple logistic regression analysis showed that individual factors, work organization factors, job characteristics, and awkward work postures were associated with the frequency of reporting WMSDs in specific parts of workers. Comparatively poor physical health (including moderate, poor, and very poor) was positively correlated with neck, shoulder, hand, and foot WMSDs (OR=1.479-4.077); working with an uncomfortable posture (OR=1.983) and doing the same task almost every day (OR=1.783) were positively correlated with neck pain; doing the same task almost every day (OR=2.408) and neck twisting for a long time (OR=1.830) were positively correlated with shoulder pain; bending wrists up and down frequently (OR=1.948) and bending wrists for a long time (OR=2.081) were positively correlated with hand pain; prolonged standing (OR=1.953) and often working overtime (OR=1.627) were positively correlated with feet pain; sufficient rest time was negatively correlated with WMSDs in the neck, shoulders, hands, and foot (OR=0.544-0.717). Conclusion The prevalence rate of WMSDs in furniture manufacturing workers is relatively high, and neck, feet, shoulders, and hands are the most involved body parts. The frequency of reporting WMSDs is related to individual factors, work organization factors, job characteristics, and awkward work postures.
