Perfil da dor lombar em trabalhadores dos restaurantes de uma universidade pública do sul do Brasil / Lower back pain profile in restaurant workers at a public university in southern Brazil

A realização das tarefas dos trabalhadores em restaurantes universitários (RUs) envolve movimentos repetitivos de coluna, levantamento de pesos excessivos e permanência na postura em pé por períodos prolongados de tempo, sendo indicada avaliação da região lombar desses trabalhadores. Assim, o objetivo deste estudo foi traçar o perfil da dor lombar em trabalhadores dos RUs de uma Universidade Pública do Sul do Brasil. Trata-se de estudo quantitativo observacional de corte transversal, no qual foram selecionados participantes de 18 a 59 anos, de ambos os sexos, que exerciam alguma função dentro dos restaurantes de uma universidade do sul do Brasil e que relataram presença dor lombar. Os participantes foram avaliados, por: questionário sociodemográfico, escala visual numérica da dor (EVN), amplitude de movimento (ADM) da coluna lombar e questionário Start Back Screening Tool Brasil (SBST). Os resultados são apresentados em frequência absoluta e relativa, correlação de Spearman, e as variáveis numéricas em média e desvio padrão ou mediana, mínimo, máximo. Foram incluídos no estudo 28 participantes sendo 71,4% mulheres, que possuíam média de idade de 36,3 (±10,8) anos. O relato de dor acima de 4 na EVN foi de 71,4% dos participantes e todos possuíam diminuição da ADM em todos os movimentos avaliados na coluna lombar. A maioria (71,4%) apresentou baixo risco para fatores psicossociais pelo SBST. O perfil dos trabalhadores de restaurantes da universidade avaliada é caracterizado por ser prioritariamente realizado por mulheres, sendo que estas trabalhadoras apresentaram quadro álgico intenso e limitação dos movimentos articulares na região lombar.

The tasks that workers in university restaurants (URs) perform involves repetitive movements of the back, lifting excessive weight, remaining in a standing posture for prolonged periods of time, and, thus, an evaluation of the lumbar region of these workers is indicated. Therefore, the objective of this study was to outline the profile of lower back pain in workers from the URs of a Public University in the South of Brazil. This is a cross-sectional, observational, quantitative study, in which participants aged 18 to 59 years, of both sexes, who performed some function within the restaurants of a university in southern Brazil and who reported the presence of lower back pain were selected. Participants were evaluated by a sociodemographic questionnaire, a visual analogue scale (VAS) for pain, a range of motion (ROM) of the lumbar spine evaluation, and the Brazilian Start Back Screening Tool (SBST) questionnaire. Results are presented as absolute and relative frequencies, with a Spearman correlation, and numerical variables as mean and standard deviation or median, minimum, and maximum. Twenty-eight participants were included in the study, 71.4% of whom were women, with a mean age of 36.3 (±10.8) years old. The report of pain above 4 in the VAS was 71.4% of the participants and all had a decrease in ROM in all movements evaluated in the lumbar spine. Most (71.4%) had low risk for psychosocial factors by SBST. The profile of restaurant workers at the evaluated university is characterized by being primarily performed by women, and these workers presented severe pain and limited joint movements in their lumbar region.

Structural and physical-functional deficits in lower limbs with fractures and treated surgically / Déficits estruturais e físico-funcionais do membro inferior com fratura e tratado cirurgicamente / Déficits estructurales y físico-funcionales del miembro inferior con fractura tratado quirúrgicamente

Abstract 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.

Variations in gait features in elderly adults during walking considering their balance

The aim of this study was to evaluate the influence of balance on the spatiotemporal features, lower-limb kinematics, and center of mass (COM) of the non-faller elderly during walking. In this study, 20 healthy elderly women (age, 76.2 ± 5.6 years; height, 150.1 ± 3.2 cm; weight, 55.8 ± 9.0 kg) were enrolled. Based on the Berg balance scale (BBS), the elderly were classified into two groups: poor balance (PB; BBS scores 0.05). The ROM of the mediolateral COM was greater in PB than in GB. Hip transversal movements in the two groups were different. The impairment of the lateral balance function might contribute to an increase in the incidence of fall events in the elderly with poor balance.

Congenital dislocation of the patella - clinical case / Luxação congênita da patela - Caso clínico

Congenital patellar dislocation is a rare condition in which the patella is permanently dislocated and cannot be reduced manually. The patella develops normally as a sesamoid bone of the femur. This congenital dislocation results from failure of the internal rotation of the myotome that forms the femur, quadriceps muscle and extensor apparatus. It usually manifests immediately after birth, although in some rare cases, the diagnosis may be delayed until adolescence or adulthood. Early diagnosis is important, thereby allowing surgical correction and avoiding late sequelae, including early degenerative changes in the knee. A case of permanent dislocation of the patella is presented here, in a female child aged seven years.

A luxação congênita da patela é uma patologia rara, em que a patela se encontra permanentemente luxada e manualmente irredutível. A patela desenvolve-se normalmente como um osso sesamoide do fêmur. A luxação congênita da patela resulta da falência da rotação interna do miótomo que forma o fêmur, músculo quadricípite e o aparelho extensor. Usualmente manifesta-se imediatamente após o nascimento, embora em alguns casos raros o diagnóstico possa ser adiado até a adolescência/idade adulta. O diagnóstico precoce é importante, permite a correção cirúrgica, evita as sequelas tardias, notadamente alterações degenerativas precoces do joelho. É apresentado um caso de luxação permanente da patela, numa criança de sexo feminino, com sete anos.

Stationary cycle training for improving lower limb muscle tension and motor function in children with spastic cerebral palsy / 中华物理医学与康复杂志

Objective To observe the effects of stationary cycle training on lower limb muscle tension and motor function in children with spastic cerebral palsy.Methods Sixty-seven children with spastic cerebral palsy were divided into a treatment group (n =34) and a control group (n =33).Both were treated with routine rehabilitation therapy,including neurodevelopment treatment,massage and physical agent therapy.The treatment group additionally cycled on a stationary bicycle for 20 min a day,five days a week for 3 months.Muscle tension in the children's adductor,hamstring and gastrocnemius muscles was evaluated using the modified Ashworth scale (MAS),while the adductor angle,popliteal fossa angle and foot dorsiflexion angle were measured using a joint protractor.Moreover,the 88-item version of the Gross Motor Function Measure (GMFM-88) was used to evaluate gross motor function.Results After treatment the average muscle tension of both groups was significantly lower than before treatment.The average muscle tension scores of the adductors,hamstrings and calf muscles of the treatment group [(1.79±0.54),(1.00±0.60),(2.29 ±1.77)] were significantly lower than those of the controls [(1.82 ± 0.53),(1.15 ± 0.44),(2.52 ± 1.89)].The adductor angles,popliteal fossa angles and foot dorsiflexion angles of both groups were significantly larger than before treatment,and the angles in the treatment group [(97.06 ± 19.03) °,(53.38 ± 12.54) ° and (8.38 ± 9.11) ° respectively] were significantly larger on average than those in the control [(98.94 ± 21.42) °,(56.52 ± 12.90) ° and (5.30 ± 14.30) ° respectively].After treatment the total GMFM scores of both groups were better than before treatment,but the treatment group's average score(138.18 ± 54.86) was significantly better than that of the control group(112.21 ± 62.44).Conclusion Three months of stationary cycle training can effectively reduce the muscle tension of children with spastic cerebral palsy and improve their motor function.

Effects of Plyometric Training on Ankle Joint Motion and Jump Performance / 대한스포츠의학회지

The purpose of this study was to quantify the effect of plyometric training (PT) in changes of jump abilities and ankle joint motions on repeated-rebound-jumps exercise without buffer function of lower limb joints. Seven female collegiate runners executed 10-repeated rebound jumps training (10 RJ) on a switch mat with maximum effort. Each subject executed the training program twice a week for 5 consecutive weeks. Parameters of repeated-rebound jumps training involved jump height (m), the contact time (s), flight time (s), and rebound jumps index (=RJ-index). Three-dimensional ankle joint kinematics of each subject were captured using ten motion capture systems (250 Hz). As a result, RJ-index, jump height, and flight time were increased significantly between pre-and post-test (p<0.001). But, the contact time decreased significantly. The relationships between rebound jumps index and jump height and between rebound jumps index and the durations of contact phase were highly correlated (r=0.858, r=-0.739; p<0.001). In addition, the time (%) between start and finish phase in the dorsiflexion angle of ankle joint was reduced significantly between pre-and post-test (p<0.001). The repeated-rebound-jumps exercise was shown to have an effect on improvement in stretch-shortening cycle (SSC) performance of lower limb joints in distance runners. The RJ-index and the time between start and finish phase in the dorsiflexion angle of ankle joint was shown to be a valid evaluation index of SSC performance. Therefore, repeated-rebound-jumps exercise is a significant training protocol where ankle behavior improves and where the performance of stretch-shortening cycle is enhanced.

A influência da ocupação profissional na flexibilidade global e nas amplitudes angulares dos membros inferiores e da lombar / The influence of occupation on overall flexibility and lower limb and lumbar range of motion

O desenvolvimento tecnológico no ambiente de trabalho gerou um aumentono tempo em que os indivíduos permanecem sentados enquanto trabalhamem escritórios. Isto pode estar influenciando negativamente capacidades físicas inatas como a flexibilidade da cadeia posterior do corpo, porém poucos são os estudos que avaliaram a influência do trabalho nesta capacidade física. Esta avaliação pode contribuir para intervenção precoce e paralela à atividade ocupacional, prevenindo disfunções musculoesqueléticas. O objetivo foi verificar se a atividade profissionaldetermina alguma modificação na flexibilidade global da cadeia posterior na postura de flexão do tronco e analisar os segmentos corporais contribuidores desta modificação. Participaram do estudo 24 mulheres saudáveis e sedentárias, entre 18 e 55 anos, que trabalhavam em manutenção (n=13) e em escritório (n=11). Foram avaliados o teste do terceiro dedo ao solo (fita métrica) e os ângulos articulares tíbio-társico, do joelho, do quadril, da lombar e a técnica de Chaffin Modificadapor meio da fotogrametria (software SAPo) na postura de flexão do tronco. Os grupos foram comparados por meio de teste t (?=5%). Mulheres que trabalham em escritório mostraram maiores distâncias do terceiro dedo ao solo (p=0,0518) e técnica de Chaffin Modificada significativamente menor . (p=0,0134), enquanto os ângulos tíbio- tarsico e do quadril mostraram valores marginalmente maiores nestas mulheres (p=0,0609 e p= 0,0713, respectivamente). Mulheres que trabalhampredominantemente na posição sentada apresentam menor flexibilidade global da cadeia posterior quando comparadas com as que realizam um trabalho que exige flexão cíclica do tronco. Sugere-se que os ângulos tíbio-tarsico e quadril, em conjunto, são os segmentos corporais que contribuem para esta menor flexibilidade.

The technological development in the working environment has prolongedsitting time for office employees. This prolonged sitting time may negatively influence innate physical capacities such as flexibility of the posterior chain; however, few studies have evaluated the influence of occupation on this physical capacity. This assessment might contribute to establish an early intervention approach, in parallel to the occupational activity, in order to prevent musculoskeletal dysfunctions. The aim of this study wasto determine whether occupational activity influences posterior chain muscle flexibility during trunk-flexed posture and to analyze the body segments that are responsible for any flexibility changes. Twenty-four healthy women aged 18 to 55 years, who worked in cleaning and maintenance (n=13) and in offices (n=11), participated in the study.The following measurements were obtained to evaluate trunk flexion: fingertip-to-floor distance test (measuring tape), tibiotarsal angle, knee extension/flexion angle, hip angle, lumbar angle, and modified Chaffin technique (digital photogrammetry using the SAPo software). The groups were compared using the independent t-test. Women working inoffices presented the worst fingertip-to-floor test result (p=0.0518) and a lower modified Chaffin technique value (p=0.0134), whereas their tibiotarsal and hip angles were marginally greater (p=0.0609 and p=0.0713, respectively). Women who mainly work seatedpresented lower overall flexibility of the posterior chain muscles than women who perform occupations that require cyclic flexion of the trunk. The tibiotarsal and hip angles seem to be the body segments responsible for this reduction in flexibility.

OBJETIVOS: Analisar os resultados do tratamento cirúrgico de pacientes com lesão isolada do tendão do músculo subescapular. PACIENTES E MÉTODOS: Foram avaliados 12 pacientes com lesão isolada do tendão do músculo subescapular submetidos a tratamento cirúrgico entre junho de 1987 a abril de 2005. Em 10 pacientes a lesão era de origem traumática. Oito eram do sexo masculino e quatro do feminino. O tempo de dor no período pré-operatório variou de três dias até 72 meses. Sete pacientes foram submetidos a tratamento artroscópico e cinco por cirurgia aberta. Sete possuíam lesão completa do tendão e cinco lesões parciais. RESULTADOS: A mobilidade no período pós-operatório dos pacientes passou de elevação média de 135º para 150º, a rotação lateral média de 60º para 50º e a rotação medial passou de média de T12 para T9. Os seis pacientes que praticavam esportes, retornaram ao nível de atividade prévio. Pelo método da UCLA, 11 pacientes tiveram resultados excelentes e bons. Houve associação de 33,3 por cento de lesão do tendão da cabeça longa do bíceps braquial. CONCLUSÃO: O tratamento cirúrgico da lesão isolada do tendão subescapular propicia bons resultados e satisfação na parte dos pacientes.

OBJECTIVES: To evaluate the results of surgically treated patients with isolated subscapularis tendon injuries. PATIENTS E METHODS: Twelve patients with isolated tears of the subscapularis muscle tendon surgically treated between June 1987 and April 2005 were evaluated. Ten patients had traumatic injuries. Eight patients were males and four females. The duration of preoperative pain ranged from three days to 72 months. Seven patients were submitted to arthroscopic procedures and five to open surgical ones. Seven had complete tendon ears while five showed partial injuries. RESULTS: The mean range of motion of the patients has improved from pre-operative to final evaluation from 135º to 150º of forward lifting, from 60º to 50º of lateral rotation, and from T12 to T9 for medial rotation. Six patients returned to their pre-injury level of sports activity. Using the UCLA score, 11 patients showed excellent or good results. 33.3 percent of the cases were associated to injuries of the long head of the brachial biceps. CONCLUSION: Isolated tears of the subscapularis tendon addressed with surgery lead to good outcomes and patient satisfaction.

Limited Joint Motion in Type II Diabetic Patients; Association with Diabetic Complications and Related Disease

OBJECTIVE: This research aimed to evaluate the relationship of limited joint motion (LJM) and shoulder adhesive capsulitis with diabetic complications and related diseases in type II diabetic patients. METHOD: A cross sectional study in 155 type II diabetic patients was done. The presence of LJM and shoulder adhesive capsulitis was sought. The diseases closely related to diabetes were recorded. The patients were assessed for retinopathy, nephropathy, and neuropathy. RESULTS: The prevalence of LJM and shoulder adhesive capsulitis in type II diabetic patients was 32.3% and 29.7%, respectively. Development of LJM and shoulder adhesive capsulitis was correlated with age and duration of diabetes. Higher blood HbA1c level was noticed in mild and moderate degree of LJM. The prevalence of shoulder adhesive capsulitis was shown association with LJM. The prevalence of LJM was associated with a history of myocardial infarction and chronic diabetic complications. The prevalence of shoulder adhesive capsulitis was associated with retinopathy, carpal tunnel syndrome, and autonomic neuropathy. CONCLUSION: According to the results, around 30% of type II DM patients could have hand LJM and should adhesive capsulitis, which suggested more attention and effort to prevent the LJM and shoulder adhesive capsulitis were needed.

Methods of Treatment for Improving Joint Motion After Synovectomy in Tb. Knee / 대한정형외과학회잡지

In the treatment of Tb.knee, the preservation of mobility is an important issue, there are many difficulties due to pain and swelling in the trial of early ROM exercise, and various problems such as the recurrence of Tb. lesions, delayed wound healing and draining sinus formation. We analysed 30 cases of Tb. knee treated with synovectomy during 10 years since March, 1979. In Group I (25 cases), early ROM exercise were started about 4 weeks after synovectomy. And in Group II (5 csses), arthroscopic adhesiolysis was performed after minimum 6 month immobilization and chemotherapy following synovectomy. We compared the two Groups and the results were as followings: 1. Male was 15 patients and female was 15 patients, the average age was 28.1 years. 2. The average follow-up period was 18.3 months. 3. In Group I, the ROM exercise was performed before 4 weeks in 9 cases and after 4 weeks in 16 cases postoperatively. The average final ROM was 68.9° 4. Draining sinus formation was in 4 cases in Group I. 5. In Group II, arthroscopic adhesiolysis was performed in 5 cases after synovectomy and chemotherapy for average 8.8 months ranging from 6 to 14 months. 6. The average final ROM at follow-up was 111° in Group II. 7. In a case with the severe involvement of bone and cartilage in Tb. lesion at the synovectomy, ROM was reduced gradually to 50° after arthroscopic adhesiolysis. We could gain ROM of 120° by TKR. 8. Draining sinus formation was not found in Group II.
