Abstract(s)
With ageing, physiological curves of the spine and the musculoskeletal system may change over the years influenced, among other factors, by lifestyle and adoption of bad postures. These postures are based on a sedentary lifestyle, but can be improved by diferente types od feedback (visual, tactile and verbal), expressive and used in physiotherapy clinical practice.
To analyze the relation between sigittal spinal curves during vertical self-stretching and age with diferente types of feedback, in the sitting position.
This cross-sectional study consisted of 86 physically active volunteer participants, aged between 21 and 84 years old (male = 34 and female = 52). The craniovertebral angle (CVA) was assessed using the Postural Assessment Software (SAPO). The thoracic (TA), lumbar (LA) and scral hip (SHA) angles were assessed by the Spinal Mouse®. The angles of the spine were measured in four sitting positions: relaxed position and vertical self-stretching with visual, tactile and verbal feedback. Descriptive statistics were usedto characterize the sample and Parametric Tests (Pearson´s correlation coeficiente test) and nonparametric tests (Spearman´s correlation coeficiente test). The level of significance for the tests was set at p=0.05(95% confidence interval).
In the relaxed sitting position, it was found that with the evolution of age, theCVA decreased (r=0.40, p˂0.001) and the TA (r=0.60, p˂0.001), respectively, greater cervical anteriozation and greater thoracic kyphosis; LA decreased (r=-0.50, p˂0.001) and SHA increasd (r=0.32, p=0.003), respectively, greaer lumbar lordosis and greater pelvic tilt in the anterior direction. With the use of visual, tactile and verbal feedbacks, a high negative association was observed between CVA and age (respectively, r=-0.50, p˂0.001; r=-0.50, p˂0.001; r=-0.60 p˂0.001), a strong positive association between TA and age, respectively r=0.70, p˂=0.001; r=0.70, p˂0.001; r=0.70, p˂0.001. There was a week negative association between LA and age during the self-stretching with diferente feedbaks, respectively, r=-0.10, p=0.299; r=-0.10, p=0.371; r=-0.20, p˂0.054; and alow association between SHA and age, respectively, r=-0.14, p=0.188; r=-0.14, p=0.184; r=-0.044, p=0.733.
With ageing, participants pesented na increase of the forward head position and the thoracic kyphosis. Moreover with ageing, lumbar curve and sacral hip angle increased, with a marked lack of lumbar lordosis ant anterior pelvic tilt in younger individuals. However, with the use of the three feedbacks during self-stretching, there was na improvement in the sagial curves of the spine at all ages. Verbal feedback seemed to be the one that ledto importante changes. The implementation of feedbacks in clinical practice is extremely importante to corretthe posture at any age.
