Summary

This trial tests whether a 3-week rehabilitation program using an exoskeleton can help people who have had a stroke correct a condition called lateropulsion, where the body leans to one side due to a distorted sense of vertical. Participants will receive 15 sessions combining exoskeleton-assisted balance exercises with physiotherapy focused on upright orientation. The study measures changes in how accurately participants perceive verticality, which is key to balance and walking.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: A 3-week rehabilitation program combining exoskeleton-assisted balance and gait exercises with physiotherapy focused on vertical body orientation.
What this could lead to: If it works, this could point toward a more effective rehab approach to help stroke survivors with lateropulsion regain balance and upright posture.
What could go wrong: This is a very small pilot study with only 3 participants, so results may not apply broadly. The program is intensive and may not be feasible for all stroke patients.

Inclusion Criteria: * Right hemispheric first and unique ischemic stroke between 2 weeks and 6 months old (subacute phase) ; * Presence of lateropulsion, assessed by the Scale for Contraversive Pushing (2 ≤ SCP \< 5) * Presence of contralesional VV bias (VV \> 4°) * Right handedness defined by a Edinburgh score ≥0,39 * Being hospitalized in a Physical Medicine and Neurological Rehabilitation (PMR) facility. * Have given a written and informed consent Exclusion Criteria: * Medical instability making evaluation impossible, * Comprehension or cognitive or behavioral disorders, or depressive symptoms that compromise participation in the program * Postural disorders or body geometry disorders that interfere with balance for a reason that is independant of the stroke * Morphological contraindications to the use of the Atalante® robot (segment length or joint ranges; height \<155cm; weight \>100kg), * Severe spasticity (\>3 on the modified Ashworth scale) in the adductors, quadriceps, hamstrings and triceps surae * Presence of a pressure sore at the areas of contact with the Atalante® robot, * History of osteoporotic fractures. * Pregnancy and breastfeeding
