The Barthel index: italian translation, adaptation and validation

The Barthel Index (BI) is widely used to measure disability also in Italy, although a validated and culturally adapted Italian version of BI has not been produced yet. This article describes the translation and cultural adaptation into Italian of the original 10-item version of BI, and reports the procedures for testing its validity and reliability. The cultural adaptation and validation process was based on data from a cohort of disabled patients from two different Rehabilitation Centers in Rome, Italy. Forward and backward translation method was adopted by qualified linguist and independent native English official translators. The scale obtained was reviewed by 20 experts in psychometric sciences. The Italian adapted version of the BI was then produced and validated. A total number of 180 patients were submitted to the adapted scale for testing its acceptability and internal consistency. The total time of compilation was 5 ± 2,6 minutes (range 3-10). Validation of the scale was performed by 7 trained professional therapists that submitted both the translated and the adapted versions to a group of 62 clinically stable patients (T-test=-2.051 p=0.05). The internal consistency by Cronbach’s alpha resulted equal to 0.96. Test – retest intra – rater reliability was evaluated on 35 cases; at test-retest was ICC=0.983 (95%IC: 0.967-0.992). This is the first study that reports translation, adaptation and validation of the BI in Italian language. It provides a new tool for professionals to measure functional disability when appraising Italian speaking disable patients in health and social care settings along the continuum of care

Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector

This paper presents the measurement of fducial and diferential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity diference. The measured fducial cross sections for electroweak and inclusive W±W±jj production are 2.92 ± 0.22 (stat.) ± 0.19 (syst.)fb and 3.38±0.22 (stat.)±0.19 (syst.)fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95% confdence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons H±± that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an H±± mass near 450 GeV, with a global signifcance of 2.5 standard deviations

Search for dark photons in rare Z boson decays with the ATLAS detector

A search for events with a dark photon produced in association with a dark Higgs boson via rare decays of the standard model Z boson is presented, using 139     fb − 1 of √ s = 13     TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider. The dark boson decays into a pair of dark photons, and at least two of the three dark photons must each decay into a pair of electrons or muons, resulting in at least two same-flavor opposite-charge lepton pairs in the final state. The data are found to be consistent with the background prediction, and upper limits are set on the dark photon’s coupling to the dark Higgs boson times the kinetic mixing between the standard model photon and the dark photon, α D ϵ 2 , in the dark photon mass range of [5, 40] GeV except for the Υ mass window [8.8, 11.1] GeV. This search explores new parameter space not previously excluded by other experiments

Early versus delayed rehabilitation treatment in hemiplegic patients with ischemic stroke: proprioceptive or cognitive approach?

BACKGROUND: Early/intensive mobilization may improve functional recovery after stroke but it's not clear which kind of "mobilization" is more effective. Proprioceptive Neuromuscular Facilitation (PNF) and Cognitive Therapeutic Exercise (CTE) are widespread applied in post-stroke rehabilitation but their efficacy and safety have not been systematically investigated. AIM: To compare PNF and CTE methods in a two different time setting (early versus standard approach) in order to evaluate different role of time and techniques in functional recovery after acute ischemic stroke. DESIGN: We designed a prospectical multicenter blinded interventional study of early versus standard approach with two different methods by means of both PNF and CTE. SETTING: A discrete stroke-dedicated area for out-of-thrombolysis patients, connected with two different comprehensive stroke centres in two different catchment area. POPULATION: 340 stroke consecutive patient with first ever sub-cortical ischemic stroke in the mean cerebral artery (MCA) territory and contralateral hemiplegia admitted within 6 and 24 hours from symptoms onset. METHODS: All patients were randomly assigned by means of a computer generated randomization sequence in blocks of 4 to one to the 4 interventional groups: early versus delayed rehabilitation programs with Kabat's schemes or Perfetti's technique. Patients in both delayed group underwent to a standard protocol in the acute phase. PRIMARY OUTCOME: disability at 3-12 months. Disability measures: modified Rankin Score and Barthel index. Safety outcome: immobility-related Adverse Events. SECONDARY OUTCOME MEASURES: Six Minutes Walking Test, Motricity Index, Mini-Mental State Examination, Beck Depression Inventory. RESULTS: Disability was not different between groups at 3 months but Barthel Index significantly changed between early versus delayed groups at 12 months (p .01). Six Minutes Walking Test (p .01) and Motricity Index in both upper (p .01) and lower limbs (p .001) increased in early versus delayed groups regardless rehabilitation schedule. CONCLUSIONS: A time-dependent effect of rehabilitation on post stroke motor recovery was observed, particularly in lower limb improvement. According to our results, rehabilitation technique seems not to affect long term motor recovery. CLINICAL REHABILITATION IMPACT: these results show a significant effect of time but not of technique that may impact the decision making in the acute phase of care

Evaluation of the disciplinary competences of the students of the bachelor’s degree in physiotherapy at “Sapienza” University of Rome through the TECO. A cross-sectional study

The objective of the study is to evaluate whether the TECO-D is a useful tool for measuring the skills acquired by students during three years of the physiotherapy bachelor’s degree course at the “Sapienza” University of Rome. The sample was recruited between October and December 2017. To be included in the study, the participants had to be enrolled in the bachelor’s degree course in physiotherapy at the “Sapienza” University of Rome and had to be on track with the course’s prescribed completion timeframe. The distribution of the scores for the TECO-D shows an increasing average (Standard Deviation) from 147.1 ± 34.5 in the first year up to 227.1 ± 17.8 for graduating students. Progress testing is a form of assessment in which groups of learners of different seniority (i.e., different classes in a curriculum) are given the same written test. The test is comprehensive by sampling all relevant disciplines in a curriculum, usually determined by a fixed blueprint. The total score of the TECO-D exponentially increased between the first and second years of the course. In fact, the score, at the first year of the course, was averaged at 147 ± 34.5 and increased up to 204 ± 23.2 in the second year. Regarding the third year of the course and the undergraduates, there was an increase, but the latter was less significant. Because of this, we can say that the TECO-D is a great tool for measuring student’s knowledge in order to evaluate study programs
