Objective: From the functional perspective of human movement, we analyzed transitions made by older adults (OA) when going from prone decubitus to standing position and the time taken to perform this action, due to the inability, in a high percentage of this population, to independently incorporate after suffering a fall. Design and sample: Cross-sectional observational studies, in which 119 functionally independent OA were evaluated, being 3 of them finally excluded. Each of the 116 participants (mean age: 72.5 ± 6.48) were video recorded standing 3 times from the floor. In the visual analysis of each performance we used a graphical battery of 10 positions classified by letters, which allowed us to establish sequences of positions in the transitions from prone to standing. The incorporations were timed. Results: The sample had 11 different bipedal incorporation strategies, with a higher concentration of transitions in sequences of 3 positions, highlighting as principals: RIJ (upright trunk four supports Bear Walk), RIB (upright trunk four supportssquatting) and RIK (upright trunk four supports squatted kneeling or half kneeling). Regarding the average time of incorporation, the subjects under 70 required less than 4 seconds, the group between 70 and 79 had times under 5 seconds and the OA over 80 required more than 5 seconds (p <0.05), which indicates that as the OA get older they would require more time to stand up from the floor and with the analysis of mean differences we corroborated (p <0.05) that there is a significant difference. Conclusions: Based on the OA group studied, results show that acquiring the standing position from the most prone sequences using 3 motor positions, highlighting the RIJ strategy, had a good applicability (see appendix 1). As for the time of incorporation, it was shown that OA would require more time to incorporate themselves from the floor to standing position. With all, is important recollected more research to implement future preventive therapies for important syndrome in OA such as falls and its aftermath.
