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

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Exo group | Experimental | During the 6-week intervention period, the Exo group will complete 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. During sessions with the exoskeleton, the patient will perform ambulatory exercises with the device, with a gradual increase of intensity through the sessions. Conventional therapy corresponds to physiotherapy as part of post stroke standard of care of the center (tasks such as lower and upper limb practice, walking in parallel bars, etc., but this list is not exhaustive and depends on the practice of the therapists/centers). |
|
| Control group | No Intervention | During the 6-week intervention period, the Control group will complete 5 sessions per week of conventional therapy (i.e., 30 one-hour sessions). |

| Use of the Atalante exoskeleton | Device | Six weeks of exoskeleton sessions replacing conventional therapy sessions three times a week |

| Walking recovery expressed by the proportion of patients reaching a Functional Ambulation Category (FAC) score of 4 or higher at the end of the intervention period, assessed without the exoskeleton. | The FAC is a 6-item ordinal scale that classifies the level of support needed to walk safely, irrespective of the use of a lower extremity orthosis or walking aid, ranging from 0 (unable to walk without the assistance of two people) to 5 (independent walking on uneven surfaces and on stairs). | End of the intervention period (week 6) |
| Measure | Description | Time Frame |
|---|---|---|
| Walking recovery expressed by the proportion of patients reaching a FAC score of 4 or higher at six months post stroke, assessed without the exoskeleton. | 6 months post stroke | |
| Time to reach FAC score of 4 or higher | Day 1 (± 3 days), week 2 (± 3 days) and week 4 (± 3 days) after the beginning of the intervention period, end of the intervention period (Week 6 ± 3 days), discharge from hospital and 6 months post stroke (± 6 days). |

| Change in walking speed measured with the 10 Meter Walk Test (10MWT) | The 10MWT is used to assess gait speed in meters/second over a short distance. Two tests are successively administered, barefoot, at comfortable then at maximal walking speed without walking aids. If a patient is unable to ambulate at all, a score of 0 m/s is documented. | Day 1 (± 3 days), end of the intervention period (Week 6 ± 3 days), discharge and 6 months post stroke (± 6 days) |
| Changes in static and dynamic balance measured by the Berg Balance Scale (BBS) | The BBS is a subjective, ordinal scale that assesses the ability to safely balance and avoid falls, during a series of functional tasks. It is thus also a measure of the amount of assistance needed to perform these tasks safely. In most items, the subject must maintain a given position for a specified time or complete moving tasks of varying difficulty. Subject receives a score from 0-4 at each of the 14 items on the ability to meet these balance dimensions. | Day 1 (± 3 days), end of the intervention period (Week 6 ± 3 days), discharge and 6 months post stroke (± 6 days) |
| Change in transfer time from wheelchair to toilet and back to wheelchair | The purpose is to record the time needed by the patient to do the transfer wheelchair /toilet seat/ wheelchair. Reduction of this time could mean an improvement of independence in daily life for stroke patients for whom transferring to the toilet is a common difficulty. | Day 1 (± 3 days), end of the intervention period (Week 6 ± 3 days), discharge and 6 months post stroke (± 6 days) |
| Changes in maximal clinical muscle extensibility XV1 and maximal range of active motion XA against the resistance of the key lower limb muscles using the Five Step Assessment | Measurements of XV1 and XA for soleus, gastrocnemius, gluteus maximus, hamstrings, vastus and rectus femoris muscles, using to the Five Step Assessment
| Day 1 (± 3 days), end of the intervention period (Week 6 ± 3 days), discharge and 6 months post stroke (± 6 days) |
| Changes in anxiety and depression scores using the Hospital and Depression scale (HAD) | The HAD is a two-dimension self-administered questionnaire developed to identify depression and anxiety among physically ill patients. Identifying these disorders and the context in which they develop is interesting as motivation of the patient seems to have an important impact on his progression. It consists of 14 items rated with a score from 0-4, divided into 7 items for anxiety and 7 items for depression based on the concept of anhedonia. | Day 1 (± 3 days), end of the intervention period (Week 6 ± 3 days), discharge and 6 months post stroke (± 6 days) |
| Changes in perceived quality of life assessed by the Short Form-36 (SF-36) | The SF-36 is a self-administered questionnaire that provides an evaluation of the generic Quality of Life. The version used is the RAND-36 Item Health Survey. There are 36 items (or questions) divided into eight domains: Physical component:
| Day 1 (± 3 days) and 6 months post stroke (± 6 days) |
| Subject and Therapist satisfaction and willingness to continue training sessions | The subject is asked to answer two questions regarding his satisfaction and willingness to continue training sessions. The therapist answers one question on his satisfaction. The score of each question is evaluated with a 5-level Likert scale. | End of Week 1 (± 3 days), end of Week 3 (± 3 days) and end of the intervention period (Week 6 ± 3 days) |
| Perceived workload by the therapists conducting sessions assessed with the NASA Task Load Index | The NASA Task Load Index is a multidimensional, subjective scale that rates perceived workload in order to assess a task.There are six items, answered by the therapists after the therapy session:
| End of Week 1 (± 3 days) and end of the intervention period (Week 6 ± 3 days) |
