About

The goal of the study is to show the concordance between the dual-task test achieved usually on an electronic treadmill and the dual-task test achieved with a cyclo-ergometer.

Full description

Usually, dual task tests are only achieved on electronic treadmills. Patients who are coming to perform these tests are mainly subjects with various levels of cognitive disorders and with a high risk of fall because of potential motor and cognitive disorders.

The investigator will select patients referred for double task walking tests. After the walking test, investigator will perform dual-task tests with a new bicycle device "Cycléo BRAU" which allows the patients to achieve mental tasks while cycling. The aim of using a bicycle is to limit the risk of falls compared to the treadmill or walking task. The "Cycléo BRAU" device is equiped with a video projector which projects an environment of virtual reality. It allows cycling without resistence and thus is not based on any incremental worload. The mental tasks on bicycle will be of increasing difficulty and parameters such as cycling speed will be recorded. Loss of speed regularity will be considered as an abnormal response. The task for which cycling is stopped will be recorded and compared to the results of the usual walking test.

Practice dual-task tests

Experimental group

Description:

The study consists to practice these dual-task tests with a new device which name is "Cycléo BRAU" that allows to the patients to achieve carefully an attentional task: cycle. Results will be compared tothe results obsvered during the routine GAITRITE analysis ( a validated tool for elderly patients and gait analysis).

Device: GAITRITE®

Device: Cycléo BRAU
