Objective: To observe possible changes in frailty phenotype classification over time. Method: 40 individuals of both genders aged over 65 years, living in the metropolitan region of Belo Horizonte, Minas Gerais and identified in a base line Rede FIBRA assessment as frail, who could walk independently or with the aid of devices and who had no illnesses that would prevent tests being carried out, , were considered. A standardized survey previously established by Rede FIBRA was administered. Results: The initial sample was composed of 40 individuals with a mean age of 78.03 (±6.46) years. After 24 months, a follow up of the 22 individuals from the initial sample that could be found was performed. The frailty phenotype classification scores of the same 22 subjects from the two samples were compared. After comparing the groups, it was found that 16 individuals had a lower number of frailty phenotype positive items in the follow up, three had higher positive scores and there was no change in the score of three individuals between assessments ( p=0.004). Conclusion: This study found that a large majority of individuals showed improvement in their frailty phenotype classification.

The findings demonstrated that both the GT3XActiGraph accelerometer and the Google Fit smartphone application do not provide valid measures of energy expenditure in chronic stroke individuals during fast overground walking.
