Study Summary

The present clinical investigation - EarlyExo, is an interventional, international, multicentric, prospective, single-blinded randomized controlled trial.

This clinical investigation is designed to test the hypothesis that early and intense introduction of walking sessions assisted by the Atalante exoskeleton, in a sample of hemiparetic patients with still non or poor ambulatory capacities (FAC 0 or 1) between one- and four-months post stroke, would result in a better recovery of functional walking compared to a control group only receiving conventional therapy. Improved recovery will be measured through the proportion of patients reaching a FAC score of 4 or higher at the end of the intervention period. The tested hypothesis is that this proportion will be higher in the Exo group.

The duration of the intervention period in both groups is 6 weeks.

  • For the Exo group: 3 sessions per week (i.e., 18 one-hour sessions) with the Atalante device and 2 sessions per week (i.e., 12 one-hour sessions) of conventional therapy.

  • For the Control group: 5 sessions per week of conventional therapy (i.e., 30 one-hour sessions).

The study will include 66 patients (33 in each arm) and takes place in two French centers, two German centers and one Spanish center.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • >18 years old

  • First clinically significant disability due to stroke

  • Hemiparesis in acute-subacute phase (1 to 4 months since lesion) due to a stroke

  • Functional Ambulation Category score (FAC) <2

  • Patient with health insurance

  • Informed and willing to sign an informed consent form approved by the EthicsCommittee. For clarity, if a motor impairment prevents the subject from signing byhimself, he/she can still be included if the signature can be done by an impartialwitness.

Exclusion

Exclusion Criteria:

  • Muscle overactivity in hip adductors, hamstrings, quadriceps and plantar flexors,which interferes with exoskeleton use, based on clinician investigator's opinion

  • Recent fracture (< 3 months) or any therapy inducing secondary osteoporosis

  • Excessive joint mechanical pain in the lower limbs based on clinician investigator'sopinion

  • Pressure sore grade I or more over contact zones with Atalante system, according tothe International Pressure Ulcer Classification System NPUAP - EPUA

  • Medical contra-indication to medium intensity physical strain

  • Orthostatic hypotension (loss of > 20 mmHg systolic BP after 3 minutes in standingposition)

  • Uncontrolled seizures

  • Morphological contra-indications to the use of Atalante (as per user's manual)

  • Pregnant woman

  • Adults who lack the capacity to provide informed consent, and all those personsdeprived of their liberty in prisons or other places of detention

  • Concurrent participation in another interventional trial
