Primary Outcome Measures
NameTimeMethod
Cadence of walking (in cycles.min-1)60 days

The kinematics of the initiation of walking and walking will be appreciated thanks to the variables calculated at the level of the joints of the lower limbs as well as the spatio-temporal parameters without and with management of obstacles (taking a step, balloon)

Range of motion in the lower limbs in degrees60 days

The kinematics of the initiation of walking and walking will be appreciated thanks to the variables calculated at the level of the joints of the lower limbs as well as the spatio-temporal parameters without and with management of obstacles (taking a step, balloon)

Step length (in m)60 days

The kinematics of the initiation of walking and walking will be appreciated thanks to the variables calculated at the level of the joints of the lower limbs as well as the spatio-temporal parameters without and with management of obstacles (taking a step, balloon)

Walking speed (in m.s-1)60 days

The kinematics of the initiation of walking and walking will be appreciated thanks to the variables calculated at the level of the joints of the lower limbs as well as the spatio-temporal parameters without and with management of obstacles (taking a step, balloon)

Secondary Outcome Measures
NameTimeMethod
Muscle contractions determined by the electromyogram (EMG) (mV)60 days

The motor patterns (organizations of muscle contractions determined by measuring the EMG of muscles representative of walking) (mV) of the femoral, semi-tendinous, anterior tibial and soleus rectus muscles will be measured using surface EMG , for the two locomotor tasks (walking and initiation to walking), during walking at spontaneous speed (without double task, without crossing an obstacle).

Ocular fixation time (measured in ms)60 days

Visual exploration will be appreciated by the Ocular fixation time (measured in ms), when initiating walking, walking at spontaneous speed and when passing obstacles with or without a cognitive task. Visual exploration will also be measured after emotional priming when initiating walking and walking. This emotional priming will consist of the transfer of images from the International Affective Picture System (IAPS). This measurement will be carried out using eyetracking glasses worn by patients.

Displacements (in mm) during walking60 days

The displacements (in mm) of the center of the body mass and of the center of pressure on the anteroposterior and mediolateral axes will be derived from the force platforms during the initiation of walking in different conditions (without and with emotional priming).

Acceleration (in mm.s-2) during walking60 days

The acceleration (in mm.s-2) of the center of the body mass and of the center of pressure on the anteroposterior and mediolateral axes will be derived from the force platforms during the initiation of walking in different conditions (without and with emotional priming).

Joint angles60 days

The articular moments and torques (Nm) at the joints of the lower limbs during the initiation to walking will be calculated from kinematic data from the motion analysis laboratory and dynamics of force platforms (without and with priming emotional).
