RESUMO
INTRODUCTION: The Toe Walking Tool (TWT) is a clinical screening instrument which helps in the differentiation of children with normal development, idiopathic toe-walking or toe-walking due to a medical cause. AIM: To carry out the translation and cross-cultural adaptation of the TWT for the Spanish pediatric population and to evaluate its content validity. SUBJECTS AND METHODS: This paper was carried out following an inverted method of translation and back-translation. Once the pre-final Spanish version was obtained, its analysis was conducted through the Delphi method by a panel of experts. The content validity of the tool explores its clarity, viability, applicability and usefulness. RESULTS: An expert panel composed by 15 professionals determine the content validity of the Spanish version of the TWT. The questionnaire translated and adapted transculturally into Spanish presented an excellent global content validity index (0.94) and the expert committee considered that the scale was easily understandable, viable, simple to apply and useful in the pediatric setting. CONCLUSIONS: The Spanish version of the TWT presents an excellent content validity and is an understandable, viable, simple and useful assessment tool. It is necessary to carry out future studies to analyze its psychometric properties with a Spanish pediatric population.
TITLE: Traduccion y adaptacion transcultural de la Toe Walking Tool: herramienta para el cribado de la marcha de puntillas.Introduccion. La Toe Walking Tool (TWT) es una herramienta clinica de cribado que permite discriminar a los niños con desarrollo normal de los que presentan marcha de puntillas idiopatica o marcha de puntillas de origen medico. Objetivo. Realizar la traduccion y adaptacion transcultural de la TWT para la poblacion infantil española y evaluar su validez de contenido. Sujetos y metodos. El proceso se realizo segun el metodo invertido de traduccion-retrotraduccion. Una vez obtenida la version prefinal en castellano, se llevo a cabo su analisis mediante el metodo Delphi por parte de un panel de expertos para analizar su validez de contenido, asi como la comprension, viabilidad, aplicabilidad y utilidad de la herramienta. Resultados. Se constituyo un panel de expertos compuesto por 15 profesionales que determinaron la validez de contenido de la version española de la TWT. El cuestionario traducido y adaptado transculturalmente al castellano presento un indice de validez de contenido global excelente (0,94). A traves del metodo Delphi se determino que la escala era comprensible, viable, de aplicacion sencilla y util en el ambito pediatrico. Conclusiones. La version en castellano de la TWT presenta una excelente validez de contenido y se considera un instrumento comprensible, viable, sencillo y util con aplicacion en la poblacion pediatrica española. En futuros estudios resulta necesario analizar sus caracteristicas psicometricas en niños con marcha de puntillas.

OBJECTIVES: To investigate the activity of the thoracic erector spinae muscles and perceived pain intensity immediately after central postero-anterior (PA) mobilisation of the thoracic spine. DESIGN: Randomised, placebo-controlled, experimental design. PARTICIPANTS AND INTERVENTIONS: Thirty-four participants with non-specific thoracic pain were randomised to the experimental group [grade III central PA mobilisation performed for 3minutes at the level of the seventh thoracic vertebra (T7)] or the placebo group (less than grade I central PA mobilisation performed for 3minutes at T7). MAIN OUTCOME MEASURES: Before and immediately after PA mobilisation, surface electromyography (EMG) was recorded from the thoracic erector spinae muscles as the participants performed 10° spine extension from a prone position for 10seconds. Each participant rated their pain intensity as an investigator performed grade III central PA over the most symptomatic thoracic segment, and the pressure pain threshold (PPT) was evaluated bilaterally over the erector spinae muscles. RESULTS: The EMG amplitude of thoracic erector spinae activity was reduced significantly after the intervention in the experimental group (P<0.05), but not in the placebo group. The difference between the groups was significant {pre-post change: placebo -14 [standard deviation (SD) 50]mV, experimental 28 (SD 48)mV; mean difference -42mV; 95% confidence interval of the difference -76 to 7; P<0.05} albeit small (Grissom=0.44). However, both groups showed a significant reduction in pain immediately after the intervention, and both groups showed a similar pre-post change in PPT. CONCLUSION: These preliminary findings indicate that grade III central mobilisation over the most symptomatic thoracic segment reduces thoracic erector spinae activity during extension of the trunk in people with non-specific thoracic spine pain. CLINICAL TRIAL REGISTRATION NUMBER: ISRCTN47601528.

The objective of this study is to analyze the effectiveness of low power laser irradiation in the bone consolidation of tibial fractures in rats. An experimental, comparative, prospective study with control group was designed. Twenty Wistar rats were grouped into control (n = 10) and experimental groups (n = 10). A tibial fracture, with a mechanical drill, was inflicted in all rats. The experimental group received ten days of low power arsenide-gallium laser irradiation of 850 nm (KLD, Sao Paulo, Brasil)-100 mW, 8 J/cm(2), 64 s. Before and after the laser treatment, a radiologic analysis was carried out in both groups, in which the rats were graded from 0 to IV according the Montoya scale of bone consolidation. Also, we histopathologically analyzed the bone to estimate the proliferation of fibroblasts, bone matrix, and angiogénesis with a microscopy, which were graded as I (thin layer of fibroblasts and osteoid matrix), II (thick layer of fibroblasts and osteoid matrix), or III (thick layer of fibroblasts and osteoid matrix and new blood vessels). Radiologic data showed that the experimental group had a higher bone consolidation of Montoya scale after ten days of laser irradiation compared to control group (P < 0.004). Histopathologic data showed more fibroblasts and angiogenesis presence in the group receiving laser irradiation, compared to control group (P < .002). The low power laser radiation therapy may expedite the bone repair after tibial fractures in rats, according to radiologic and histopathologic analysis.

Spinal manipulation (SM) is a manual therapy technique frequently applied to treat musculoskeletal disorders because of its analgesic effects. It is defined by a manual procedure involving a directed impulse to move a joint past its physiologic range of movement (ROM). In this sense, to exceed the physiologic ROM of a joint could trigger tissue damage, which might represent an adverse effect associated with spinal manipulation. The present work tries to explore the presence of tissue damage associated with SM through the damage markers analysis. Thirty healthy subjects recruited at the University of Jaén were submitted to a placebo SM (control group; n = 10), a single lower cervical manipulation (cervical group; n = 10), and a thoracic manipulation (n = 10). Before the intervention, blood samples were extracted and centrifuged to obtain plasma and serum. The procedure was repeated right after the intervention and two hours after the intervention. Tissue damage markers creatine phosphokinase (CPK), lactate dehydrogenase (LDH), C-reactive protein (CRP), troponin-I, myoglobin, neuron-specific enolase (NSE), and aldolase were determined in samples. Statistical analysis was performed through a 3 × 3 mixed-model ANOVA. Neither cervical manipulation nor thoracic manipulation did produce significant changes in the CPK, LDH, CRP, troponin-I, myoglobin, NSE, or aldolase blood levels. Our data suggest that the mechanical strain produced by SM seems to be innocuous to the joints and surrounding tissues in healthy subjects.
