Evaluation of Safety and Performance of the Atalante System With Patients With Lower Limb Paralysis
The study is a prospective, open, bicentric and observational study. It is conducted to assess the safety and performance of the Atalante exoskeleton system with patients with lower limb paralysis.
The principal objective is to assess the performance of the Atalante system in performing ambulatory functions with motor complete SCI patients characterized by the success rate in performing a 10mWT at the last session of training with the Atalante system.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The primary endpoint of the clinical investigation is defined by the success or failure at the 10 Meter Walk Test (10mWT) at the latest session.
Time Frame: At study completion, up to 3 weeks
|
The 10mWT is used to assess walking speed in meters/second (m/s) over a short distance. A clear pathway of at least 10-meter length is drawn. The start and the end point of a 10-m walkway is marked by lines. The patient starts a few steps prior the starting line; during the few steps needed to reach the starting line, the physiotherapist should stabilize the exoskeleton in the frontal plane. When the patient's first foot crosses the starting line, the test begins, and the stopwatch is started. The stopwatch is stopped at the end of the 10 meters in case of success, that is to say when the patient crosses the end line. The total time taken to ambulate is recorded. The distance covered is then divided by the total time (in seconds) taken to ambulate and recorded in meters per seconds. In case of failure, the distance walked by the patient is measured and recorded, and the speed to walk this distance is calculated as described above. |
At study completion, up to 3 weeks

Average scores on Borg CR-10 simple perception scale for the perceived exertion at the 6th and 12th sessions.
Time Frame: At study mid-term, 10 days in average and at study completion, up to 3 weeks
|
Rating of perceived exertion (RPE) is a widely used and reliable indicator to monitor and guide exercise intensity. The scale allows individuals to subjectively rate their level of exertion during exercise or exercise testing. Developed by Gunnar Borg, it is often also referred to as the Borg Scale. Despite being a subjective measure of exercise intensity, RPE scales provide valuable information when used correctly. The revised category-ratio scale (0 to 10 scale) is used:

Average scores of safety perceived by the patient on a 7-point Likert scale 7 levels at the 6th and 12th sessions.
Time Frame: At study mid-term, 10 days in average and at study completion, up to 3 weeks
|
A Likert scale is a psychometric scale commonly involved in research based on survey questionnaires. Here, the respondents specify their level of agreement or disagreement using a symmetric agree-disagree scale for a series of statements while responding to a particular Likert questionnaire item. The range of Likert scale captures the intensity of their feelings for a given item. The Likert scale ratings are:
The perceived safety is evaluated with the 7-point Likert scale on the following statement: "I felt safe during the test" |

Comparison of the NBD score before the 1st session and after the 12th session.
Time Frame: At study start, day 1 and at study completion, up to 3 weeks
|
The neurogenic bowel dysfunction score is a questionnaire including questions about background parameters, faecal incontinence, constipation, obstructed defecation, and impact on quality of life.
The NBD score is constructed from items with acceptable reproducibility and validity that were significantly associated with impact on quality of life.
The type of the stool depends on the time it spends in the colon.

|
Definition of the voiding mode at the 1st and 12th sessions.

|
The management of neurogenic bladder dysfunction is crucial in the management of paraplegic patients as it affects the morbidity of these patients.
The voiding mode is described.
The self-survey is the standard treatment when the subject has an overactive bladder.
The mictionnel mode will be informed before the first session, and at the end of the last session with the exoskeleton using an ISCOS questionnaire (International Spinal Cord Society questionnaire).

Comparison of the Visual Analogue Pain Scale at the 1st and 12th sessions.
Time Frame: At study start, day 1 and at study completion, up to 3 weeks
|
The Numeric Pain Rating Scale measures the subjective intensity of pain. The NPRS is an 11-points scale from 0 to 10: "0" = no pain; "10" = the most intense pain imaginable. The subject is asked to make pain rating corresponding to the current pain experienced. |
At study start, day 1 and at study completion, up to 3 weeks
|
Comparison of the NPSI scores at the 1st and 12th sessions.
Time Frame: At study start, day 1 and at study completion, up to 3 weeks
|
NPSI (Neuropathic Pain Sumptom Inventory) renders it suitable for the evaluation of the different dimensions of neuropathic pain syndromes. The reliability of the different descriptors appears to be sufficient. It allows to quantify the various pain symptoms that can be grouped into five dimensions (burn, deep pain, paroxysmal pain, pain caused, paresthesia / dysesthesia) |
At study start, day 1 and at study completion, up to 3 weeks
|
Patient Global Impression of Improvement (PGI-I) at the 12th session.

|
The Patient Global Impression of Improvement (PGI-I) is a global index that may be used to rate the response of the use of Atalante on the bowel function. The subject should check the number that best describes how the twelfth session condition is, compared with how it has been at the first session for the bowel function:

|
At the end of the twelfth session, the patient evaluates the interfaces and the ergonomics of Atalante (shape of the remote, mode, symbol) and the perceived safety and the level of assistance during transfer from the wheelchair to Atalante with a Likert scale. The Likert scale is a questionnaire where the subject chooses among seven-point scales:
