Evaluation of the Use of the Atalante System in Patients Presenting a Non-traumatic Hemiplegia in Acute-subacute Phase (15 Days to 6 Months).

Evaluation of the Use of the Atalante System in Patients Presenting a Non-traumatic Hemiplegia in Acute-subacute Phase (15 Days to 6 Months).

The SPIRIT study is interventional, national, prospective, open, multicentric each patient being his/her own control.

It is conducted to assess the safety and performance of the Atalante exoskeleton system in patients presenting a non-traumatic acute-subacute hemiplegia. The primary endpoint is defined by the patient's ability to perform the 10 MWT with the Atalante system.

The study will include at least 12 patients and takes place in three french rehabilitation centers.

Inclusion Criteria:

• Patient with non-traumatic vascular hemiplegia in acute subacute phase (15 days to 6 months) hospitalized in rehabilitation center,

• Patients presenting a FAC score of 0, 1 or 2,

• Patient with ischemic or hemorrhagic stroke of which etiological evaluation is complete,

• Adult patient ≥18 years old,

• Patient able to verticalize on a daily basis and having a stabilized blood pressure,

• Patient with stable medical condition at the time of inclusion in the study (absence of infectious and cardiorespiratory events),

• Patient's height is at least 1m55,

• Lengths of patient's lower limb are in the following intervals:

  • Thigh (distance gluteus maximus - patella): 56.8 and 64.8 cm,

  • Distance between the ground and the joint space of the knee (to be measured while wearing the shoes the patient intends to wear with Atalante):

    • 45.7-60.7 cm for patient with an ankle dorsiflexion ≥ 16°
    • 45.7-57.7 cm for patient with an ankle dorsiflexion > 13° et < 16°
    • 45.7-56.7 cm for patient with an ankle dorsiflexion > 10° et ≤ 13°
    • 45.7-55.7 cm for patient with an ankle dorsiflexion ≥ 0° et ≤ 10°

  • Intertrochanteric distance lower or equal to 46.0 cm when seated,
