Vieillissement: Analysis of Motor Skills in the Elderly: the Role of Cognitive Abilities for Imagining and Planning Movement.
Study Details
Study Description
Brief Summary
Falling is an event that is more frequent and severe in older age. It can lead to a loss of autonomy and a decrease in quality of life. It is therefore important to understand this phenomenon in order to better prevent it. Among the multiple risk factors associated with falling, recent research has shown a link between the decline in cognitive abilities (i.e., the mental processes that form our knowledge, such as memory) and the risk of falling. However, the impact of this cognitive decline on motor skills is still poorly understood. The purpose of this research is to study how the changes induced by aging affect motor skills. This would make it possible to take a new look at the phenomenon of falls occurring in the elderly and, in the long term, to improve the prevention and rehabilitation.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| young neurotypical subjects people from 18 to 40 years old |
Other: Sequence 1
perform arm movements towards a target
Other: Sequence 2
judge the verticality of an object
Other: Sequence 3
In standing position, point as quickly as possible with the right arm at the diode that will light up in front of the participant.
Other: Sequence 4
Composed of 5 sessions of about 15 minutes each (5 consecutive days), it will be required to perform a walking test (10 meters) in 3 different conditions and a manual dexterity test. Participants will be asked to imagine carrying out these tests during the training sessions.
Other: Sequence 5
Composed of 5 sessions of about 20 minutes each (5 consecutive days), it will be asked to perform pointing movements of the arm. It will be asked to imagine these movements during training sessions.
