Methods: Postural evaluation of 32 older adults was performed using Postural Assessment Software (SAPO). Two raters performed the procedure independently, and one of the raters repeated the process 7 to 10 days later. Reliability was assessed through the intraclass correlation coefficient (ICC) and paired and independent t-tests. SEM and MDC95 values were calculated, and Bland-Altman plots were generated. Results: The inter-rater analysis showed that the raters were not different in any of the angles. Most angles achieved good to excellent inter-rater reliability (ICC = 0.34 – 0.81) and intrarater reliability (ICC = 0.33 – 0.88) and were not different between days. The SEM was lower than 10º in most angles. The MDC95 ranged from 2.88º to 18.49º. Bland-Altman analysis indicated that most angles were within the limits of agreement. Overall, angles generated in lateral view had better reliability properties. Conclusion: Postural Assessment Software (SAPO) showed angles with distinct reliability properties in older adults. Angles that reached good to excellent intra- and inter-reliability and exhibited lower variability could be considered for assessing postural changes in older adults. MDC95 values could be used as a reference for indicating changes greater than the variability of the measurement. 2022 artículo científico 2447-2115 https://www.redalyc.org/articulo.oa?id=739780783010 en http://www.redalyc.org/revista.oa?id=7397 Geriatrics, Gerontology and Aging application/pdf Sociedade Brasileira de Geriatria e Gerontologia Geriatrics, Gerontology and Aging (Brasil) Num.1 Vol.16 |
