Robotic Strategies to Characterize and Promote Postural Responses in Standing, Squatting and Sit-to-StandLuna, Tatiana D. January 2022 (has links)
In people with neuromotor deficits of trunk and lower extremities, maintaining and regaining balance is a difficult task. Many undergo rehabilitation to improve their movement capabilities, health, and overall interactions with their environment. Rehabilitation consists of a set of interventions designed to improve the individual’s mobility and independence. These strategies can be passive, active or task-specific and are dependent on the type of injury, how the individual progresses, and the intensity of the activity.
Some of the common rehabilitation interventions to strengthen muscles and improve coordination are accomplished either by the manual assistance of a physical therapist, bodyweight suspension systems or through robotic-assisted training. There are several types of rehabilitation robotic systems and robotic control strategies.However, there are few robotic studies that compare their robotic device’s control strategy to common rehabilitation interventions. This dissertation introduces robotic strategies centered around rehabilitation ones and characterizes human motion in response to the robotic forces.
Two cable-driven robotic systems are utilized to implement the robotic controllers for different tasks.
Further details of the two cable-driven systems are discussed in Chapter 1. The validation and evaluation of these robotic strategies for standing rehabilitation is discussed in Chapter 2. A case study of a robotic training paradigm for individuals with spinal cord injury is presented in Chapter 3. Chapter 4 introduces a method to redistribute individuals’ weight using pelvic lateral forces. Chapter 5 and 6 characterizes how young and older groups respond to external perturbations during their sit-to-stand motion.
This dissertation presents robotic strategies that can be implemented as rehabilitation interventions. It also presents how individuals’ biomechanics and muscle responses may change depending on the force control paradigm.These robotic strategies can be utilized by training individuals to improve their reactive and active balance control and thus reduce their risk of falling.

The effect of bra size correction on selected postural parameterMthabela, Nosipho Pearl January 2015 (has links)
Submitted in partial compliance with the requirements for the Master's Degree in Technology : Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Introduction: Symptoms associated with large breasts result from bra strap chafing, poor body posture, headaches, neck, shoulder, thoracic and lower back pain. There is a paucity of literature quantifying objective data regarding the effect of breast size on posture. Therefore correct bra sizing may improve posture, however this is undetermined. This study aimed to investigate the effect of bra correction on selected postural parameters in order to determine its relevance in a clinical setting.
Methodology: Sixty five females who met the inclusion criteria had the following parameters recorded: age, height, weight, body mass index, occupation, and underbust and overbust bra size. An anterior-posterior, right and left lateral digital photographs were taken before and after bra correction. These were then processed using the Posture Pro software. The data was analysed using the latest version of SPSS. The results were presented by means of standard deviations and ranges and differences between pre and post measures were performed with an ANOVA.
Results: It was found that there was no correlation between changes in any of the four parameters from pre to post correction, which changed significantly with postural correction (4/43 post correction significant readings) and the demographic variables. Most participants changed to a larger cup sizes after correction which is in line with Greenbaum, (2003) who found that participants tend to buy a smaller bra size. In this study 3% of the study population changed to a bigger cup size and 97% wore bras that were too tight. Similar to the findings of Wood eta/., (2008) who found that 70% of the study population wore bras that are too small and 10% wore bras that were too big.
Conclusion: In the study on effect of incorrect bra size on selected postural parameters it was found the there were four parameters that changed significantly with p<O, 05 [ANOVA]. Further investigation needs to be done on a larger sample size, age group range, BMI and different demographic. / PDF copy unavailable. please refer to hard copy for full text information / M

Factores pronósticos en el latigazo cervicalPleguezuelos Cobo, Eulogio 12 December 2011 (has links)
Múltiples revisiones científicas han intentado determinar los factores
pronósticos en la evolución del latigazo cervical sin llegar a un consenso.
Nuestros resultados se han obtenido tras 8 años de estudio en pacientes
controlados desde la primera visita en el servicio de Medicina Física y
Rehabilitación del Hospital de Mataró. Se han utilizado escalas de valoración
fáciles de cumplimentar y cuantificar para poder obtener los resultados en el
mismo momento de la consulta. Este hecho es importante, ya que la mayoría
de las escalas que se identifican en los artículos publicados son poco prácticas
en la consulta diaria por la dificultad que conllevan en su cumplimentación y
valoración. Los factores pronósticos que hemos identificado en nuestra
muestran han sido: la edad, la presencia de “vértigos”, la intensidad del dolor
cervical inicial valorada mediante la escala analógica visual y el grado de
funcionalidad cervical inicial valorado mediante el Northwick Park Hospital Neck
Pain Questionnaire.

Combined and additive effects of assembly tasks and constrained body posturesSkelton, Sarah Anne January 2007 (has links)
Despite extensive research into musculoskeletal disorders (MSDs) they continue to plague workers. Manual materials handling (MMH), in particular the concurrence of load manipulation and awkward body posture, has been identified as a key factor in the onset of MSDs. Only a few studies have looked at the interaction between manipulation tasks and working posture during assembly tasks and as a result their relationship has not been widely explored. Assessing the stresses resulting from individual task factors and body posture in isolation and adding them together may be too simplified to estimate an overall risk profile, since this does not take into account that there may be a non-linear interaction in strain responses when manipulation task and body posture interact. Therefore, the present study investigated biophysical, physiological and psychophysical responses to combined tasks, rather than individual tasks of body posture and manipulative tasks. The objective of the research was to establish the interactive effects of constrained body postures and manipulative tasks and to identify whether a cumulative or compensatory reaction occurs during this interaction. Nine conditions were assessed in a laboratory setting, which included combinations of three working postures (standing, sitting and stooping) and three assembly tasks (torque wrenching, precision and no task). Thirty-six subjects were required to complete all nine conditions, with each condition lasting ninety seconds. Muscle activity was recorded for seven muscles from the upper extremity, trunk and lower extremity regions and was complemented by physiological (heart rate, tidal volume, minute ventilation, oxygen consumption, energy expenditure and breathing frequency) and psychophysical (body discomfort) data. At the completion of all nine conditions subjects completed a retrospective psychophysical rating questionnaire pertaining to discomfort felt during the conditions. Responses obtained for the different task and posture combinations revealed compensatory reactions (additive > combined) for most of the conditions assessed for the biomechanical and physiological responses. In the majority of cases for muscle activity, no significant differences were found between the combined and the additive effects (p < 0.05), while for the physiological responses there were mostly significant differences observed. Psychophysical responses indicated that there was a significant difference overall between the additive and combined effects. The results of this study demonstrate that in order to identify risk areas, manipulation tasks and constrained working postures may be considered either in isolation and added together (additive) or as a combined task, since there were very few significant differences observed between these two effects. Further studies are required, however, to provide conclusive evidence.

Программа физической реабилитации нарушений осанки у детей младшего школьного возраста с использованием йоги в гамаках : магистерская диссертация / Program of physical rehabilitation of posture disorders in children of primary school age with the use of yoga in hammocksФранц, Д. А., Franz, D. A. January 2022 (has links)
Осанка – привычное положение туловища в пространстве, поза, обусловленная конституционными, наследственными факторами, зависящая от тонуса мышц, состояния связочного аппарата, выраженности физиологических изгибов позвоночника. По данным мировой статистики 34-50% детей имеют разную степень нарушений осанки, а по данным ВОЗ – 80% детей и подростков имеют низкий уровень физической активности. Целью данной работы было разработать и оценить влияния программы физической реабилитации, с использованием йоги в гамаках, на степень выраженности нарушений осанки у детей младшего школьного возраста. В исследовании приняло участие 20 детей с такими нарушениями осанки как: плоская спина, плоско-вогнутая спина, сутулость, круглая спина. В качестве методов исследования степени выраженности нарушений осанки использовались: визуальный осмотр – асимметрия треугольников талии, высоты плеч и лопаток, измерение глубины шейного и поясничного лордозов, и вычисление плечевого индекса; функциональные тесты – силовая выносливость мышц спины и пресса, тест на определение подвижности позвоночника; динамометрия и координационный тест. Согласно полученным результатам, предложенная программа позволила снизить степень выраженности нарушений осанки и улучшить физическую подготовленность детей с нарушениями осанки. Так же результаты позволили подтвердить, что нарушения осанки у детей младшего дошкольного возраста поддаются физической реабилитации с использованием йоги в гамаках и могут успешно корректироваться данным методом. / Posture is the habitual position of the body in space, a posture determined by constitutional, hereditary factors, depending on muscle tone, the state of the ligamentous apparatus, and the severity of the physiological curves of the spine. According to world statistics, 34-50% of children have varying degrees of posture disorders, and according to WHO, 80% of children and adolescents have a low level of physical activity. The purpose of this work was to develop and evaluate the effects of a physical rehabilitation program using yoga in hammocks on the severity of posture disorders in children of primary school age. The study involved 20 children with such posture disorders as: flat back, flat-concave back, stoop, round back. As methods for studying the severity of postural disorders, the following were used: visual examination - asymmetry of the triangles of the waist, the height of the shoulders and shoulder blades, measuring the depth of the cervical and lumbar lordosis, and calculating the shoulder index; functional tests - strength endurance of the muscles of the back and press, a test to determine the mobility of the spine; dynamometry and coordination test. According to the results obtained, the proposed program allowed to reduce the severity of posture disorders and improve the physical fitness of children with posture disorders. The results also confirmed that posture disorders in children of primary preschool age are amenable to physical rehabilitation using yoga in hammocks and can be successfully corrected by this method.

The relationship between postural stability sway, balance, and injury in adolescent female soccer players in the eThekwini district of KwaZulu-NatalKoenig, Jean-Pierre 24 July 2014 (has links)
Submitted in partial compliance with the requirements for the Master of Technology: Chiropractic, Durban University of Technology, 2014. / Background: Poor balance is a risk factor for injury in adolescent sport including soccer. Despite the rapid growth in female adolescent soccer especially in South Africa, the association between balance and injury in this population has not been fully explored. This study aimed to determine the relationship between injury and balance. Static and dynamic balance was monitored as sway index (SI) and limits of stability direction control (LOSDC).
Objectives: The objectives of this study were to determine the body mass index of adolescent female soccer players; to determine the prevalence of injury in adolescent female soccer players; to determine static balance as revealed by the sway index (SI); to determine dynamic stability as revealed by limits of stability direction control (LOSDC) and to correlate body mass index (BMI) to sway index and limits of stability.
Method: Eighty adolescent female soccer players, between the ages of fourteen and eighteen, were recruited through convenience sampling from schools in the eThekwini district of KwaZulu-Natal. After obtaining informed consent and assent, participants completed questionnaires and were scheduled for the balance and BMI assessments. The objective data for each participant consisted of height, weight, Sway Index (SI) and Limits of Stability Direction Control (LOSDC) readings, measured using a stadiometer, electronic scale and Biodex Biosway Balance System (Biodex Medical Systems Inc., Shirley, New York) respectively. The subjective and objective data were analyzed using SPSS version 21.0 (SPSS Inc. Chicago, Ill, USA). Statistical tests included descriptive statistics using frequency and cross-tabulation. Inferential statistics using t-tests and Pearson’s correlations at a significance level of 0.05 was also incorporated. The testing of hypotheses was performed using Fisher’s Exact tests for nominal data and ordinal data. A p value of < 0.05 was considered as statistically significant. The statistical analysis also included Odds Ratio calculations.
Results: The mean body mass index of the injured participants was 23.54±3.56 kg/m2 and the mean body mass index of the uninjured participants was 23.00±4.63. Only 27.5% of the participants sustained an injury. Injured participants performed poorly on average in the SI assessment involving their eyes open when standing on a soft surface. The results were similar for the LOSDC in the overall, right, left, backward-right and backward-left directions. However, there were no significant correlations calculated. Significant relationships existed between BMI and the SI assessments in the injured participants which involved standing on a firm surface with their eyes open (p = 0.05), their eyes closed when also standing on a firm surface (p = 0.05), their eyes open when standing on a soft surface (p = 0.02), and their eyes closed when standing on a soft surface (p = 0.04). A significant relationship also existed between BMI and LOS right direction control (p = 0.02).
Conclusion: This research paper revealed that the body mass index as investigated in this study is similar to other studies involving female adolescents; soccer injury as investigated in this study is similar to other studies involving female adolescents; poor static and dynamic balance is not associated with injury in adolescent female soccer players and lastly, body mass index is linked to the balance of an individual.

The prevalence of postural deformities among children age 11 to 13 years in some Western Cape schoolsStroebel, Suzanne 12 1900 (has links)
Thesis (MScSportSc)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Postural deformities are a commonly encountered problem among children. Most of the aches
and pains of adults are the result, not of injuries, but of the long-term effects of distortions in
posture or alignment that have their origins in childhood or adolescence. Television, video
entertainment, motorized transportation, fast food and lack of regular physical activity
contribute to the poor physical condition of children. School screening for scoliosis is
mandated in schools in 26 states of the United States (US) for children between 10 and 16
years of age. Previous studies conducted in the US found that 160 out of 1000 people suffer
from scoliosis. This means that scoliosis is as prevalent as hypertension or diabetes mellitus
(Boachie-Adjei & Lonner, 1996). Identification of postural deformities at an early stage makes
early treatment possible, which may, in future, prevent serious postural abnormalities. The
American Academy of Orthopedic Surgeons approved the implementation of screening
programs in schools in 1974 (Lonstein, 1988).
Few studies have included the entire musculoskeletal system. The purpose of this study was
to determine the prevalence of postural deformities among children aged 11 to 13 years in
selected primary schools in the Western Cape. The study also proposes to investigate
factors that may influence the prevalence rate of postural deformities. These factors included
age, gender, school district, weight, height, BMI (Body Mass Index), fat%, waist-hip ratio, and
physical activity.
Letters were sent to 15 primary schools within a 30km radius of Stellenbosch. This region
included Stellenbosch, Strand, and Kuilsrivier. Four schools replied, giving permission to
conduct the study at their schools. The sample (N=288, mean age=12.36, SD=0.92)
consisted of 78 scholars from grade five; 104 scholars form grade six; and 106 scholars from
grade seven. Of the total number of scholars examined (288), 154 were boys, and 134 were
girls. Only children with parental consent were allowed to participate in the study.
Anthropometric measures included stature, mass, skinfoids (two-site skinfoid), waist- and hip
circumferences and trochanterion leg length. Level of physical activity and family history of
deformities were obtained by means of a questionnaire. The New York Posture Test was used for postural evaluation (Bloomfield et aI., 1994:320; Reedeo Inc., 2001. This Posture
Test was designed for the screening of 13 categories of deformities. Using a "see-through"
posture grid, lateral and posterior examinations were performed. The "Adam's position"
(forward bending) was used for further scoliosis evaluation.
Quantitative data was analyzed, using Statistica (Statsoft, 2001) and classification tree
methodology (Breiman et aI., 1993). The anthropometric results indicated that the subjects
had a mean stature of 1.54m, mass of 47.48kg, BMI of 19.75, waist-hip ratio of 0.79 and fat%
(Lohman, 1987) of 21.35%. The prevalence of postural deformities was as follows: Lordosis,
70%; Kyphosis, 57%; Uneven shoulders, 55%; Inclined trunk, 43%; Winged scapulae, 42%;
Pronated feet, 30%; Flat feet, 30%; Flat chest, 29%; Forward head, 28%; Protruding
abdomen, 28%; Uneven hips, 11%; Scoliosis, 10%; and Twisted head, 1%. Uneven hips,
scoliosis and twisted head were not considered for statistical purposes, because of their low
incidence compared to the other deformities. The factors that influenced the prevalence rate
of deformities the most were BMI and fat%. A higher BMI and fat% resulted in a higher
prevalence rate in most deformities.
The prevalence rate of postural deformities in this study was considerably high. Sedentary
lifestyles of children (watching television, computer games, junk food and physical inactivity)
were a contributing factor in the high prevalence rate of postural deformities. It is known that
overweight and sedentary behavior of children is increasing and this could pose an alarming
concern to the health of a child. Also, if a significant correlation does exist between the
prevalence of postural deformities and conditions such as back pain, the high prevalence rate
reported in this study is a matter of concern. / AFRIKAANSE OPSOMMING: Postuurafwykings is "n algemene probleem wat dikwels onder kinders voorkom. Baie van die
skete en pyne by volwassenes spruit nie uit beserings nie, maar vanuit langtermyn gevolge
van swak postuur wat huloorsprong uit die kinderjare het. Televisie, videospeletjies, vervoer
per motor, kitskos en gebrek aan fisieke aktiwiteit dra by tot die swak fisieke kondisie van
kinders. Evalueringsprogramme in skole word in 26 state in die Verenigde State van Amerika
(VSA) toegepas vir kinders tussen die ouderdomme van 10 en 16 jaar. Vorige studies in die
VSA het getoon dat 160 uit 1000 mense skoliose het (Boachie-Adjei & Lonner, 1996). Dit
beteken dat skoliose net so veel voorkom soos hipertensie of diabetes mellitus. Identifikasie
van postuurafwykings op "n vroeë stadium maak vroeë behandeling moontlik, wat in die
toekoms ernstige postuurafwykings kan voorkom. Die "American Academy of Orthopedie
Surgeons" het reeds in 1974 die implementering van assesseringsprogramme goedgekeur
(Lonstein, 1988).
Volgens navorsing het slegs "n beperkte aantal studies die hele spierskeletale stelsel
geëvalueer. Die doel van hierdie studie was om die voorkoms van postuurafwykings by
kinders tussen die ouderdomme van 11 en 13 jaar in geselekteerde Wes-Kaapse skole te
bepaal. Die studie het ook faktore wat "n invloed op die voorkoms van postuurafwykings kan
hê, ingesluit. Hierdie faktore het onder andere ouderdom, geslag, skool, gewig, lengte, LMI
(Liggaamsmassa-indeks), vet%, middel-heup-ratio en fisieke aktiwiteit ingesluit.
Uitnodigingsbriewe is na 15 laerskole binne "n 30km radius vanaf Stellenbosch gestuur. Dit
het ingesluit Stellenbosch, Strand, en Kuilsrivier. Vier skole het toestemming verleen om die
studie by die betrokke skole te loods. Die steekproef (N=288, gemiddelde ouderdom = 12.36,
SD=0.92) het bestaan uit 78 leerlinge uit graad vyf; 104 leerlinge uit graad ses en 106
leerlinge uit graad sewe. Uit die totale aantal leerlinge wat geëvalueer is, was daar 154
seuns en 134 dogters. Antropometriese metings het die volgende ingesluit: lengte, gewig,
velvoue (twee-velvou meting), middel- en heupomtrekke en trochanterion beenlengte.
Fisieke aktiwiteitsvlak en familiegeskiedenis van postuurafwykings is bepaal met behulp van
"n vraelys. Die "New York Posture Tesf' is gebruik vir postuurevaluasie (Bloomfield et al., 1994:320; Reedco Inc., 2001). Hierdie toets is ontwerp vir die evaluering van 13 deformiteite.
Die kinders is vanuit 'n posterior en anterior aansig ge-evalueer met behulp van 'n
"deurskynende" postuurruitnet (grid). Die "Adam's-" toets (vooroorbuig-toets) is gebruik vir
verdere evaluering van skoliose.
Statistica (StatSoft, 2001) en klassifikasieboom-metodologie (Breiman et al., 1993) is gebruik
vir statistiese ontleding. Die proefpersone het 'n gemiddelde lengte van 1.54m, gewig van
47.48kg, LMI van 19.75, middel-heup-ratio van 0.79 en vet% (Lohman, 1987) van 21.35%
gehad. Die voorkoms van die onderskeie postuurafwykings was as volg: Lordose,70%;
Kifose, 57%; Ongelyke skouers, 55%; Romp na posterior gebuig, 43%; Gevleuelde skapulas,
42%; Voetpronasie, 30%; Plat voete, 30%; Plat bors, 29%; Protraksie: skedel, 28%; Uitstaan
buik, 28%; Ongelyke heupe, 11%; Skoliose, 10%; en Gekantelde hoof, 1%. Ongelyke heupe,
skoliose en gekantelde hoof het minder voorgekom in vergelyking met die ander deformiteite,
daarom is die deformiteite nie vir statistiese analise in aammerking gebring nie. LMI en vet%
was die faktore wat die voorkoms van postuurafwykings die meeste beïnvloed het. 'n Hoër
LMI en vet% het 'n toenemende voorkoms in meeste deformiteite veroorsaak.
Die voorkoms van postuurafwyking in hierdie studie was hoog. Sedentêre leefwyses van
kinders (TV, rekenaarspeletjies, gemorskos, en fisieke onaktiwiteit) het bygedra tot die hoë
voorkoms. Die voorkoms van oorgewig en sedentêre leefwyses is besig om te verhoog by
kinders en kan ernstige gevolge vir die gesondheid van die kind inhou. Indien daar 'n
betekenisvolle korrelasie tussen die voorkoms van postuurafwykings en kondisies soos
rugpyn is, dan blyk die hoë voorkoms, wat in hierdie studie gevind is, 'n bron van
bekommernis te wees. Postuurevalueringsprogramme is 'n effektiewe metode vir die vroeë
identifikasie van postuurafwykings, aangesien dit vroeë identifikasie en konserwatiewe
behandeling moontlik maak.

The relevance of the Goldsmith Index of Body Symmetry to functional seated postureCrawford, Emily Anne January 2006 (has links)
Whilst literature exists describing prevalence and theories about mechanisms of development of deformity, there is a distinct lack of research that examines how deformity can be measured despite it being an area of identified need. This study established the inter- and intra-rater reliability of the Goldsmith Index of Body Symmetry and examined the relevance of the information it provides within the context of a comprehensive postural assessment for individuals with cerebral palsy in conjunction with a commonly used clinical assessment ... Results demonstrated that high index levels were not exclusively associated with people with windswept deformity. Postural patterns of windsweeping, frog leg (abducting) and scissor (adducting) postures and hip extension were found to occur in all categories, suggesting that asymmetry is not confined to one particular postural pattern. Clinically observable changes were identified through comparison of the supine evaluation and index scores. The flexibility of postural components (or the ability to correct asymmetry) in a supine position for the SD categories demonstrated wide variation. However, subjects in the 3+SD groupings had fixed scoliosis and the majority (83%) also had fixed pelvic obliquity and rotation. All other subjects up to the 3SD category had flexible pelvic obliquity and rotation. No definitive differences in postural components between groups were identified in sitting positions, which was attributed to the influence of gravity on the body in an upright posture. Examination of sitting ability and index level did not demonstrate any relationship, suggesting that greater independence in sitting is not necessarily associated with a lower Goldsmith Index. The study highlighted that assessment of posture is complex, and that no single tool provides the answers required to manage a person’s posture. It demonstrates the need for clinicians to be aware that subjective clinical assessment may not be sufficient to adequately assess and detect changes in posture, and that the Goldsmith Index of Body Symmetry provides objective data that can be used as a powerful adjunct in interpreting clinical assessment and supporting the evaluation of clinical interventions.

Capacidade de carga, sintomas musculoesqueléticos e classificações posturais na atividade de costureiras / Capacity of charge, musculoskeletal symptoms and postural ratings on seamstresses activityPizyblski, Elisandra Montes 29 September 2015 (has links)
Capes / O objetivo deste estudo foi encontrar correlação entre as posturas adotadas e os respectivos riscos posturais, a dor e/ou sintomas musculoesqueléticos e a capacidade de carga em costureiras de indústrias de confecção de vestuário da cidade de Ponta Grossa, Paraná. A amostra foi composta por costureiras do gênero feminino. O problema que se avista para a presente pesquisa centra-se: De que maneira, as posturas e a força de preensão manual aplicadas e utilizadas no trabalho, afetam a sintomatologia da dor e os sintomas musculoesqueléticos, em trabalhadoras de indústrias de confecção? O referencial teórico pautou-se em: indústria têxtil, características da indústria de confecção de vestuário, ergonomia, postura, efeitos causados ao trabalhador na postura sentada, coluna vertebral e a postura sentada, avaliação ergonômica, métodos de avaliação de análise postural, avaliação dos sintomas musculoesqueléticos e sua localização e avaliação da capacidade de carga. Quanto à abordagem metodológica, a pesquisa classifica-se como quali-quantitativa, descritiva e de levantamento. A pesquisa foi desenvolvida em cinco empresas do ramo de confecção do vestuário, totalizando 57 costureiras. Os instrumentos utilizados para a coleta de dados foram questionários, entrevistas, o método REBA (Rapid Entire Body Assessment) para avaliação das posturas, o Diagrama de Corlett e Manenica para a localização da dor nos segmentos corporais e intensidade e dinamômetro para medir a força de preensão manual. A pontuação média no método REBA da amostra foi de 4,75 (± 0,46). A maioria das costureiras (80,70%) respondeu que possui dor em algum segmento corporal, ou em membros superiores ou inferiores, e apenas 19,30% da amostra disse não sentir desconforto. Os segmentos corporais que as costureiras da amostra não apresentaram dor foram: a bacia, o braço esquerdo, o antebraço direito e o punho direito. Com relação aos membros superiores, o que apresentou maior relato de dor foi a região lombar, com 40,35%. A segunda região de maior dor é a cervical, com 36,84%, seguido da região da costa média com 24,56%. A quarta região foi o pescoço, com 22,80% e a quinta foi a costa superior, com 17,54%. Com relação aos membros inferiores, a maior queixa de dores foi nas pernas, com 56,14%, contra apenas 5,26% nas coxas. A média da capacidade de carga das costureiras, medida através da força de preensão manual foi de 24,7 quilos (± 5,81). Os resultados das correlações entre as três variáveis: postura, dor e capacidade de carga apresentaram correlação fraca ou ausente, pois a correlação entre postura e dor foi ausente, e as correlações entre postura e dor e entre dor e capacidade de carga foram de r: 0.017. Acompanhando o trabalho das costureiras, foi possível identificar que as principais posturas adotadas ao longo da jornada laboral podem contribuir para o desenvolvimento de lesões musculoesqueléticas. / The aim of this study was to find correlation between the positions taken and their risk posture, pain and / or musculoskeletal symptoms and the load capacity of seamstresses on the industry of clothing in the city of Ponta Grossa, Paraná. The sample consisted of seamstresses female. The problem that can be seen to this research focuses: How postures and grip strength applied and used at work, affect the symptoms of pain and musculoskeletal symptoms in workers in clothing industries? The theoretical framework was based on: textile industry, the clothing industry characteristics, ergonomics, posture, the effects caused in seated posture, spine and sitting posture, ergonomic evaluation, postural analysis of assessment methods, evaluation of musculoskeletal symptoms and assessing their location and load capacity. Regarding the methodological approach, the research is classified as qualitative and quantitative, descriptive and lifting. The research was conducted in five companies in the garment manufacturing industry, totaling 57 seamstresses. The instruments used for data collection were questionnaires, interviews, the REBA (Rapid Entire Body Assessment) method for assessment of attitudes, the Diagram Corlett and Manenica to the location of pain in the body segments and intensity and dynamometer to measure the force handgrip. The average score in REBA sample method was 4.75 (0.46). Most seamstresses (80.70%) replied that he has pain in a body part, or upper limbs or lower, and only 19.30% of the sample said no discomfort. The body segments that seamstresses sample did not experience pain were: the basin, the left arm, right forearm and right wrist. Regarding the upper limbs, which showed greater account of pain was a lumbar region, with 40.35%. The second area of greatest pain is the cervical, with 36.84%, followed by the middle coast region with 24.56%. The fourth area was the neck, with 22,80% and the fifth was the upper coast, with 17.54%. Regarding the lower limbs, the biggest complaint was pain in the legs, with 56.14%, compared to 5.26% in the thighs. The average load capacity of seamstresses, measured by grip strength was 24.7 kilograms (5.81). The results of the correlations between the three variables: posture, pain and load capacity had weak or no correlation because the correlation between posture and pain was absent, and the correlations between posture and pain and between pain and cargo capacity were r: 0017. Following the work of seamstresses, it observed that the main stances adopted during the working day can contribute to the development of musculoskeletal injuries.
