| Measure | Time frame |
|---|---|
| In comparing the values of joint angles obtained in sitting posture in two furnitures and the data obtained in the spirometric evaluation, based on the parameters evaluated, was used paired samples analysis by comparing values in orthostatic position with values in each of the furniture assessed, the values obtained from the two furnitures between itself and the values of each of the two subgroups found in conventional furniture. It was examined whether the data obtained in pulmonary assessment for each furniture. Since this analysis did not provide statistically significant difference for none of the 15 participants, we worked with the average of the individual values for each variable in each furniture. | — |

|---|---|
| In relation to the sitting posture, this study evaluated by means of photogrammetry, joint angles relating to anteriorização of the head, trunk flexion in relation to the vertical, flexion of the shoulder, elbow flexion and knee flexion, featuring the most frequent attitude of each subject for each of the furnitures, according to the group's average posture. The analysis of images, itself, was performed, using the program AutoCAD 2010 for the measurement of angles relating to anatomical points previously demarcated. These tariff estimating angles were their simple average and standard deviation and by establishing the attitude of individuals in each average furniture. In relation to respiratory function were evaluated variables: forced vital capacity, forced expiratory volume in first second, Fev1/FVC ratio, forced expiratory flow between 25% and 75% of maximum expiratory flow and CVF. | — |
