Multicomponent Exercise in the Functionality of the Elderly in the Community

Primary outcomes

1. Functional mobility change

   Time frame: Baseline, 8 weeks, 16 weeks

   Timed Up and Go Test is a validated test that consists on a timed 3 meter defined circuit after getting up from a chair and sitting in it. The categories of achievement are three: less than 10 seconds "without compromise", corresponding to normal performance; between 10.01 and 20 seconds it is considered "slight impairment or normal time for frail elderly"; more than 20.01 seconds corresponds to a degree of "functional impairment" that requires a more detailed assessment.

2. Balance change

   Time frame: Baseline, 8 weeks, 16 weeks

   Berg scale is a validated instrument to assess balance and the risk of falling associated with its loss. From 56 to 54 points, each point less is associated with a 3 to 4% increase in the risk of falling, from 54 to 46 a change in one point is associated with a 6 to 8% increase in the risk of falling, and below 36 points the risk of falling is very close to 100%, which allows the results to be divided into 4 balance categories: "Total balance problem" (≤36 points); "Serious balance problem" (37-45 points); "Moderate balance problem" (46-53 points) and "normal balance" (≥54 points).

3. Cognitive status change

   Time frame: Baseline, 8 weeks, 16 weeks

   Mini mental exam scale is a validate instrument to assess the cognitive function and the detection of potential dementia. Individuals are classified into three categories: a score equal to or less than 18 points corresponds to "severe cognitive impairment"; from 19 to 23 points "moderate cognitive impairment" and 24 or more points "normal cognitive state. The literature states that for the diagnosis of dementia, the scale results must be cross-checked with schooling, however when the objective is not to diagnose dementia, but only to characterize and assess changes in cognitive status, the crossing of the scale results with schooling does not justified.
