Objective : Sustained bed rest impairs many bodily functions. Verticalization restores gravitational challenge and the use of several organs. The Atalante™ exoskeleton (Wandercraft) is the only self-balanced exoskeleton, which allows walking without canes. We assessed multi-tissular effects of mobile reverticalization using Atalante™ in neurological bed- or wheelchair-bound patients.

Material / Patients and Methods : Observational cohort study. Inclusion criteria: bed- or wheelchair-bound for >2 weeks and <1 hour per day of stance, due to a central neurological disorder. Sessions with exoskeleton were 3/week, integrated in routine care. Data collected at baseline and after eight weeks (W8) included: cardiovascular (echocardiography, EKG, blood pressure lying and standing), pulmonary (spirometry), bone (densitometry, biochemical markers), bowels (daily stool frequency, Bristol Stool Scale), urinary (urinary flow, postvoid residual volume, urinary symptom profile questionnaire, USP), cognitive (trail making test, TMT-B), anxiety and depression (HAD), and quality of life (SF12).

Results : Five patients with central nervous system injury (4 women; age (46.5[41.7-53], median [IQR]; 2 hemiparesis, 1 tetraparesis, 1 paraparesis, 1 parkinsonism) were recruited. There was no fall and the sessions were well tolerated. Intermediate W8 results in two patients show a decrease in bone tissue resorption markers, and improvements in TMT-B test (time and number of errors), USP questionnaire and HAD scores.

Discussion - Conclusion : Using the self-balanced Atalante™ exoskeleton is feasible in a neurorehabilitation service and well tolerated. It may reduce bone resorption, and improve urinary function and some cognitive and psychological parameters. The remainder of the data is currently being collected and will be presented at the SOFMER 2021.
