Abstract
BackgroundOne of the reasons that make scoliosis a disease that scares so much the parents is its specific characteristic of being difficult to detect on its onset.The aim of this paper is to check the possible usefulness of a simple tool (the torsion bottle) that has been developed with the aim to offer an instrument for home use by parents but also for screening purposes in the low-income countries.MethodsStudy design: retrospective analysis to evaluate intra-operator reliability of the tools and inter-operator repeatability using the torsion bottle.For the first and the second part of the study, 35 subjects were measured.The goal of the first experiment was to evaluate the reliability of the torsion bottle to identify all individuals who experienced a thoracic or lumbar prominence equal or greater than 7°.The secondary aim was to verify the reliability of blinded inter-operator assessments, performed with the torsion bottle by two physiotherapists on the same patients.ResultsThe reliability of the assessments of the torsion bottle has been performed with the Kappa statistic to evaluate the measurement agreement.The results have shown that the intra-operator reliability of the tool is very high between the measurements collected with the scoliometer® and those collected with the torsion bottle (kappa = 0.9278; standard error = 0.7094).The data of the second part of the study show that the inter-operator reliability is good (kappa = 0.7988; standard error 0.1368).ConclusionThe collected data showed that the torsion bottle revealed itself as an efficient tool to execute a basic screening to identify the presence of a prominence in a significant group of adolescents.

One of the reasons that make scoliosis a disease that scares so much the parents is its specific characteristic of being difficult to detect on its onset
The main aim was to compare the measurements collected with the torsion bottle and the same measurements collected with the scoliometer® in a population of patients accessing our clinic for the rehabilitation treatment, measured according to our standard evaluation protocol
The following table shows the detail of the measurements taken for the first part of the study (Table 2): Column 1: gender of the subject Column 2: the result of the measurement performed with the torsion bottle and the positive or negative hypothesis of the presence of a prominence equal to or greater than 7° Column 3: the measurement of the angle trunk rotation performed with the scoliometer®
Summary
One of the reasons that make scoliosis a disease that scares so much the parents is its specific characteristic of being difficult to detect on its onset. It is possible to recognize the appearance of the spinal curves when the disease is already severe. A frequent monitoring of the clinical signs of scoliosis is the simplest solution [1,2,3]. One of the most important clinical signs of this disease is the prominence [4]. The presence of the prominence is internationally recognized as an indisputable element of the pathology [5,6,7]
