Fisioter Mov. 2013 jul/set;26(3): 587-94 Melo J Filho, Menossi BRS, Preis C, Bertassoni L Neto, Stabelini A Neto 588 jovens da Universidade Estadual do Norte do Paraná (UENP), Centro de Ciências da Saúde, Jacarezinho (PR). Resultados: A amostra do trabalho foi composta de 108 indivíduos, 17 do gênero masculino e 91 do gênero feminino, apresentando médias e desvios padrão respectivamente de: idade 19,44 ± 1,73 anos, estatura 167 ± 8 cm, peso 60,48 ± 11 kg e índice de massa corpórea (IMC) 21,70 ± 2,80 kg/m². Dos participantes, 20% apresentaram dor lombar. Na comparação entre grupos de indivíduos com dor lombar e sem dor mediante testes de estabilidade lombopélvica, não se observou diferenças significativas, p > 0,05 para todos os testes, mesmo com divisão por gênero, onde o percentual dos indivíduos com dor foi de 18,68% no grupo feminino e de 29,41% no masculino. Conclusão: Constatou-se que os adultos jovens com dor lombar não se apresentaram com a musculatura estabilizadora lombopélvica significativamente diferente quando comparados com os sem dor.[P]Palavras-chave: Estabilização.

Background: Postmenopausal women typically present loss of bone mineral density (BMD), muscular strength, and postural balance. However, there is no consensus in the literature on the correlation between these variables. Objectives: Our objective was to verify the correlation between BMD, isokinetic peak torque of knee extensors and flexors, and static postural balance in postmenopausal women. Methods: Fifty-one postmenopausal women underwent BMD evaluation through dual-energy X-ray absorptiometry (DXA) for four bone regions (lumbar spine, femoral neck, total hip, and trochanter). Muscular strength of knee extensors and flexors was evaluated in an isokinetic dynamometer at 60 and 180 degrees per second in the dominant lower limb. Static postural balance was evaluated on a force platform during five different tasks (bipodal eyes open, bipodal eyes closed, semi-tandem eyes open, semi-tandem eyes closed, and unipodal). Statistical analysis involved Spearman's correlation coefficient (rho). Results: There was no significant correlation between BMD and isokinetic peak torque of knee extensors and flexors. Approximately half (27 of 60) of the postural balance variables presented significant inverse correlations (p < 0.05) with BMD and of these, the majority (22 of 27) presented moderate correlation (rho between -0.49 and -0.30). Most correlations were for bipodal support tasks with eyes open and eyes closed. Conclusion: Greater postural oscillation in different balance tasks was correlated with lower BMD in postmenopausal women. Therefore, it is suggested that intervention protocols for women with impaired BMD, especially osteoporotic, consider balance training as part of rehabilitation.
Introduction Rupture of the anterior cruciate ligament (ACL) is one of the frequent traumatic injuries of the knee joint complex, and the isokinetic dynamometer is essential to assess and measure its joint function. Objective To analyze the volume of physical therapy treatment using the same protocol with different duration in patients undergoing ACL reconstruction. Methods This is a prospective observational cohort study. The sample consisted of 13 adult male individuals who underwent ACL reconstruction surgery. Participants were divided into two groups: accelerated treatment (AC) and non-accelerated treatment (NAC). Participants underwent a standardized protocol of post-reconstruction physio-therapy, starting in the immediate postoperative period. The AC group performed the treatment three times a week, with a duration of 4 hours each session for 6 months, while the NAC performed twice a week with duration of two hours each session for eight months. Results The groups showed the same behavior during the post-reconstruction treatment periods, showing that regardless of time, the results were beneficial at the end of the treatment. However, in the accelerated protocol, the injured limb showed a significant difference for extender peak torque (PTEXT) in the preoperative and 4-month postoperative period (230.5 vs 182.6), 4-month postoperative period and final (182.6 vs 242.1) in the AC group, while in the NAC group there was no significant difference between times in this same limb. Conclusion Greater volumes of weekly training characterized better results, showing that rehabilitation time is not a predictor of discharge, but rehabilitation time obtains good results for the variables.

Background: The prevalence of low back pain in adolescents is close to that found in the adult population. In view of the relationship between low back pain and the resistance of the spine stabilizing muscles, studies have sought to identify the ability of specific motor tests to predict this condition. Objectives: Our objective was to verify the predictive ability of three motor tests related to musculoskeletal fitness to identify adolescents with low back pain. Methods: The sample consisted of 150 adolescents, of both sexes, aged between 15 and 19 years. The Nordic questionnaire validated for Brazilian adolescents was applied to identify those with low back pain. Subsequently, three motor tests (one-minute sit-up test, Sorensen test and lateral plank test) were applied. Statistical analysis involved the ROC curve, to identify the Area Under the Curve (AUC), assuming a 95% confidence interval. Results: It was observed in males that all the tests had a low AUC (between 0.56 and 0.57), without statistical significance (p > 0.05). For females, AUC ranged from 0.62 to 0.66, with statistical significance (p < 0.05) for the cut-off points identified in the one-minute sit-up test (≤ 24 repetitions) and Sorensen test (≤ 28 seconds), however, without significance (p > 0.05) for the lateral plank test. Conclusion: Motor tests of abdominal and paravertebral muscle resistance were not predictors of low back pain in male adolescents. Despite the low accuracy, the cut-off points identified in the one-minute sit-up test and Sorensen test, can be used with some caution to predict low back pain in female adolescents.
Introduction: Physically active individuals constantly seek resources that can improve their muscle performance, avoid the appearance of lesions and even relapses. Kinesio Taping has been used for both treatment/prevention of injury and to improve functional performance. The isokinetic dynamometer enables rapid quantitative analysis of many parameters of muscle function, being the peak torque the most representative in research and clinical practice. Objective: To compare the concentric peak torque isokinetic in active individuals with and without the application of kinesio taping. Method: 10 male volunteers were evaluated and submitted to the IPAQ questionnaire, where they were considered actives. Then, were realized isokinetic evaluations into steps: Phase Control (without application of elastic taping) and Phase Bandage (with application of placebo and original bandage). The same protocol isokinetic repetitions of 5 to 60 ° / s knee flexion and extension was adopted in all the stages for the reliability and reproducibility of the data. Results: The application of taping in physically active individuals in isokinetic evaluation did not increase the concentric peak torque at 60 °/s. Conclusion: Was observed reliability and reproducibility of the results, however, no significant differences were observed in concentric peak torque isokinetic of the quadriceps of active individuals with and without the application of the original kinesio taping and placebo.
