Secondary Outcome Measures
- Evaluate the patient's ambulatory ability without the Atalante exoskeleton with the Functional Ambulation Classification. [At baseline, day 0 and at study completion, up to 10 days]
Evaluation of the walk performance with the FAC classification. 0: Nonfunctional ambulation Ambulator-Dependent for Physical Assistance Level II Ambulator-Dependent for Physical Assistance Level I Ambulator-Dependent for Supervision Ambulator-Independent Level Surfaces only Ambulator-Independent
- Evaluate the settings of the walking parameters of the exoskeleton deemed most efficient by the patient (step length, cadence) [At study start, day 2 until study mid term, day 5]
During sessions 2 to 5, the physiotherapist will vary the step length and cadence of the exoskeleton's walk. Each parameter will be tested over a distance of 10 meters. Perceived exertion and perceived safety will be assessed by the patient using a Likert Scale. Physiotherapist satisfaction (evaluated on a Likert Scale) will be assessed at the end of the test. Likert scale : "strongly disagree" "disagree" "neither agree or disagree", "agree", "strongly agree",
- Evaluate the assistive control settings [At study start, day 2]
The test is performed in EXERCISE mode. Atalante accompanies the movements of the upper body while stabilizing the entire system. As a result of this transfer, a quasi-static step is triggered. This step is more or less assisted: the effort provided by the patient is modulated by the physiotherapist (100% of assistance equals 0% effort of the patient, Atalante performs the movement instead of the patient). The patient takes a step forward and at the end of the step, Atalante returns to the EXERCISE mode and is ready to connect a second quasi-static step by soliciting the opposite leg. The patient has to transfer his/her weight for 2 seconds on the opposite leg to trigger the step. Values of tested assistance levels assessed will be collected as perceived exertion, perceived safety and physiotherapist satisfaction (evaluated on a Likert Scale). Likert scale : "strongly disagree" "disagree" "neither agree or disagree", "agree", "strongly agree",
- Evaluate the assistive control settings [Study mid term, day 4]
The test of dynamic assistance is performed in WALK mode. The patient starts by leaning the right side (or left side). Then, as soon as the user presses WALK button, a first step is triggered by the exoskeleton. Next steps are more or less assisted depending on the level of assistance chosen by the physiotherapist (100% of assistance equals 0% effort of the patient, Atalante performs the movement instead of the patient). The patient must initiate each step by pushing on the opposite leg and making a pelvic rotation towards the forward foot. Values of tested assistance levels assessed will be collected as perceived exertion, perceived safety and physiotherapist satisfaction (evaluated on a Likert Scale). Likert scale : "strongly disagree" "disagree" "neither agree or disagree", "agree", "strongly agree",
- Evaluate the patient's ability to perform weight transfer on the hemiplegic side or the healthy side [At study start, day 2 until study mid term, day 4]
Success/ Failure to the exercise: transfer of weight to the right or left side until the sound signal is triggered
- Evaluate the patient's ability to perform a semi-squat [At study start, day 3 until study mid term, day 5]
Success/ Failure to the exercise: perform a semi-squat
- Evaluate the patient's ability to perform functional tests with the Atalante exoskeleton with a Time Up and Go test [At study mid-term, day 7 until study completion, day 9]
Success/ Failure to the TUG test (Time Up and Go test)
- Evaluate the level of assistance needed by the patient from the healthcare staff to perform tests [Throughout study completion, an average of 10 days]
The therapist will record the level(s) of assistance needed to perform each test and detail the moment on which assistance was needed during the test. The level of assistance will be determined with the number of times the therapist will have helped the patient during the tests, as well as the type of assistance he/she will have provided. The physiotherapist will select on a scale the level of assistance he/she provided during the test:. None (0% of assistance) - Minimal (0-25% assistance) - Moderate (25-50% assistance) - High (50-75% assistance) - Maximum (75-100% assistance).
- Evaluate the time needed for the patient to don and doff [At study completion, day 10]
Collection of data regarding the time needed for patient to donning and doff
- Evaluate the patient's physical and cognitive conditions using the Berg Balance Scale [At baseline, day 0 and at study completion, up to 10 days]
The Berg Balance Scale (BBS) is a 14-item objective measure that assesses static balance and risk of fall in adult. In this 14-item scale, patient must maintain positions and complete moving tasks of varying difficulty. In most items, patient must maintain a given position for a specified time. Patient receives a score from 0-4 on his/her ability to meet these balance dimensions: 0-20 on the BBS represents balance impairment; 21-40 on the BBS represents acceptable balance; 41-56 on the BBS represents good balance. This measure will be performed during sessions 0 and 10 in order to assess a potential variation.
- Evaluate the patient's physical and cognitive conditions [At baseline, day 0]
Evaluation of the level of aphasia by the aphasia severity rating scale from the Boston Diagnostic Aphasia Examination. The degree of aphasia will be evaluated using the aphasia severity rating scale from the Boston Diagnostic Aphasia Examination (BDAE). BDAE is designed to diagnose aphasia and related disorders. This test evaluates the various conceptual modalities (auditory, visual and gestural), the processing functions (comprehension, analysis, problem solving) and the response modalities (writing, articulation and manipulation). The aphasia severity rating scale from the BDAE will be done at baseline in order to describe the population participating in the study.
- Evaluate the safety of the exoskeleton by collecting the incidence of points of contact, induced pain, edema, and other potential adverse events [Throughout study completion, an average of 10 days]
Collection of medical events relating to cutaneous, algological and infectious morbidity
- Evaluate the level of effort perceived during each test by using the Borg scale [Throughout study completion, an average of 10 days]
Rating of perceived exertion (RPE) will be used to assess the effort perceived by patient at each session. 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. The revised category-ratio scale (0 to 10 scale) is used: 0 Null 1 Very easy 2 Somewhat easy- 3 Moderate 4 Somewhat hard 5 Hard 6 7 Very hard 8 9 10 Very, very hard
- Evaluate the level of security perceived during each test by using a 5-level Likert scale [Throughout study completion, an average of 10 days]
Perceived safety during tests will be assessed by each patient using a 5-point Likert scale format ranging from 5)"strongly agree", 4)"agree", 3)"neither agree or disagree", 2)"disagree" and 1)"strongly disagree". The range of Likert scale captures the intensity of his/her feeling for a given item
- Evaluate the level of anxiety of patient related to the use of the exoskeleton [At study start, day 1 and at study completion, up to 10 days]
Collection of the patient's level of anxiety assessed by a 5-level Likert scale: "strongly disagree" "disagree" "neither agree or disagree", "agree", "strongly agree",
- Evaluate the emergence of musculoskeletal disorders in the therapist [At baseline, day 0 and at study completion, up to 10 days]
Evaluation of musculoskeletal disorders developed by healthcare professionals in the use of exoskeleton with a Nordic style questionnaire. The Nordic Musculoskeletal Questionnaire (NMQ) is a 2-section questionnaire. The aim was to develop and test a standardized questionnaire methodology allowing comparison of low back, neck, shoulder and general complaints. The NMQ can be used as a questionnaire or as a structured interview.
