After stroke, a lot of patients present an hemiparesis and gait disorders. They need walking aids like quadripod cane or rolling cane.

The quadripod cane confers a great stability but implies a walk in 3 times, thus consume more energy. The pause time necessary for the displacement (uplift) of the cane disappear with the Wheeleo.

The investigators will study many spatio-temporal parameters to determine which one allows to decrease the walking speed.

Hemiparesis affects 65% of stroke patients and cause gait disorders. During rehabilitation, patients often need technical aids to the the return to walk.

For example, they can use the quadripod cane and the rolling cane, called Wheeleo. Regarding the first one, as its name indicate, there are 4 feet while the other model has 4 wheels.

Deltombe and al. proved that the walking speed is higher with a rolling cane. The investigators will recruited stroke patients and study many spatio-temporal parameters with a gait analysis system, when participants are walking with the two walking aids.

Participants will achieve 6 minutes walking test and a 10 meters walking test, with a wearable inertial systems on their shoes.

The investigators wish to reveal which spatio-temporal parameters most influence walking speed.
