Effects of Motor Imagery on Motor Learning and Motor Retention in Octogenarian.

Study Overview
=================
Brief Summary
-----------------
Aging is associated with impairments in cognitive function, particularly motor learning and memorizing, impacting functional capacities. Older adults are still able to learn new skills but at a slower rate, and they forget quickly the new-learned skill because of an alteration in motor memory. Motor imagery, which is a mental simulation of an action without actual execution, has been demonstrated to improve performance in young adults and stabilize performance after a short break in older adults. However, in very old adults (>80 years old) for whom the decline in motor and cognitive functions is greater, it is unknown whether motor imagery training during a short break is still efficient. Previous studies on old adults were performed on upper limb muscles. Because aging differentially affects upper and lower limb muscles, the present study will aim to explore the effects of motor imagery on motor memorizing in both upper and lower limb muscles.

Detailed Description
-----------------
The primary purpose is to evaluate the effectiveness of motor imagery to improve the performance of very old people (> 80 years) through learning a task of the upper limbs.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Performance at the manual task (Nine Hole Peg Test (NHPT)) (s) | Comparison of performance at the manual task (Nine Hole Peg Test (NHPT)) results in post-test between experimental and control group. Measured in seconds when performing manual task. | Day: 0 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Performance at the motor task (s) | Comparison of performance at the motor task (hopscotch) results pre-test and post-test between experimental and control group. Measured in number of tests. | Day: 7 | 
| Learning capacity of manual task (Nine Hole Peg Test (NHPT)) | Comparison of manual task (Nine Hole Peg Test (NHPT)) results between pre-test and post-test. Measured in seconds. | Day: 0 | 
| Learning capacity of motor task (hopscotch) | Comparison of motor task (hopscotch) results between pre-test and post-test. Measured in number of tests. | Day: 7 | 
| Test of 6 minutes walking (m) | Comparison of test of 6 minutes walking results between experimental and control group. Measured in meters. | Day: 0 | 
| Test of Get-up-and-Go (s) | Comparison of test of Get-up-and-Go results between experimental and control group. For test of Get-up-and-Go, participants will be asked to stand from a seated position, walk 3 meters at their usual pace, turn around, walk back to the chair, and sit down. Measured in seconds when performing test. | Day: 0 |
