Design outcomes
Primary
| Measure | Time frame |
|---|---|
| An increase in global cognitive function scores is expected, as verified by the Montreal Cognitive Assessment (MoCA), with a difference of at least 5% expected between pre- and post-intervention scores. ;Improvements in executive function are expected, verified by a reduction of at least 60 seconds in the time taken to complete the Trail Making Test (TMT) before and after the intervention. ;An improvement in balance is expected, verified by an increase of at least 5% in the Mini-BESTest score compared to the pre-intervention assessment. ;An increase in gait speed is expected, verified by a reduction of at least 0.05 m/s in patient performance during the 10-meter Walk Test. | — |
Secondary
| Measure | Time frame |
|---|---|
| Some improvement is expected in the performance of the respective assessment instruments (Montreal Cognitive Assessment (MoCA); Trail Making Test (TMT); Mini-BESTest and 10m walk test) during the reassessment that will be carried out four weeks after the last session. | — |
