- Centre Hospitalier Universitaire de Nice
- Brief Summary
The dual task (walking and cognitive task at the same time) is increasingly used in geriatrics in protocols for detecting people who are falling and/or for highlighting cognitive disorders. However, frail elderly people tend to get tired quickly and a lack of awareness of the effects of fatigue on dual-task performance could alter the diagnosis.
There are two types of fatigue: mental fatigue and peripheral muscle fatigue. Each participant will do both types of fatigue over 2 appointments spaced by 7 days so that the subject can recover from induced fatigue. The sequence of fatigue tasks will be randomized.
At the first appointment (day 0):
1. Pre-fatigue assessment :
* The subject must walk on 10m with round trip for 1min.
* the subject must do the arithmetic count of 3 in 3
* Then comes the evaluation in double task (walking and counting at once for 1min). The subject must walk on 10m with round trip for 1min by doing the arithmetic count of 3 in 3 at the same time.
2. mental fatigue task or muscle fatigue task (randomized)
3. post-fatigue assessment (the same as pre-fatigue assessment)
7 resting days
Second appointment (day 7)
1. Pre-fatigue assessment :
* The subject must walk on 10m with round trip for 1min.
* the subject must do the arithmetic count of 3 in 3
* Then comes the evaluation in double task (walking and counting at once for 1min). The subject must walk on 10m with round trip for 1min by doing the arithmetic count of 3 in 3 at the same time.
2. mental fatigue task or muscle fatigue task (randomized)
3. post-fatigue assessment (the same as pre-fatigue assessment)

- Primary Outcome Measures
Name Time Method Dual task performance after muscular fatigue at inclusion (day 0) Dual task performance (DTEspeed motor performance; DTEcog cognitive performance) will be compared before and after a protocol of peripheral mental and muscular fatigue.
For Dual Task Performance, the cognitive task performance (maximum count count - error count) performed alone (single ST task) and performed while walking (double ST task) will be compared.Dual task performance after cognitive fatigue at day 7 Dual task performance (DTEspeed motor performance; DTEcog cognitive performance) will be compared before and after a protocol of peripheral mental and muscular fatigue.
For Dual Task Performance, the cognitive task performance (maximum count count - error count) performed alone (single ST task) and performed while walking (double ST task) will be compared.
