RESUMO
The posture undergoes changes during aging and may serve as a marker for the evaluation of the thoracic spine. This study aimed to correlate the variables for the evaluation of thoracic spine mobility and propose predictive equation models from the measurements of the thoracic Schober test and the digital inclinometer in older adults. The mobility of thoracic flexion and extension by levels (T1, T8 and T12) of 41 older adult subjects (66 ± 7 years) was quantified with a digital inclinometer (degrees) and Schober's test (cm). There was a moderate positive correlation between the digital inclinometer and the Schober test at T1 (r = .69), T12 (r = .60), and total flexion levels T1 to T12 (r = .74). Simple linear regression equations showed that thoracic Schober predicts thoracic mobility measures for these same levels. Moderate to strong correlations were observed between the inclinometer and the Schober Test measurements. The development of predictive equation models based on the thoracic Schober test could potentially enhance the ability to predict spinal mobility in physically independent older adults.
