In 2019, approximately 2.4 billion people worldwide required rehabilitation for various health pathologies, a 63% increase since 1990. It has been suggested that current rehabilitation frameworks (inpatient, outpatient, and community-based) are insufficient to meet local population needs due to issues like long waiting times, lack of facilities, prioritization, funding, and accessibility.Patients with lower limb weaknesses, resulting from various conditions (for example stroke, traumatic brain injury, spinal cord injury and others) require long-term management and motivation for engagement, which are crucial for functional outcomes. This highlights the need for sustainable gait and balance rehabilitation.
New technologies like exoskeletons have shown promising results in short-term inpatient programs, improving gait, balance, and quality of life, however, long-term follow-up data are still needed.
The present clinical investigation is a national, prospective, open-label interventional trial, proposing a 12-month outpatient rehabilitation program with the Atalante X exoskeleton to treat lower limb weakness and/or impairments in 100 participants. The rehabilitation program consists of at least one exoskeleton rehabilitation session per week. At the end of the first-year experimental phase, participants can continue for an additional year in the voluntary phase. The program aims to explore the potential long-term effects of supervised robotic rehabilitation on motor, cognitive, bowel, bladder functions, quality of life, and well-being. Assessments are conducted at baseline, after 4 and 12 months of exoskeleton rehabilitation, and at 16 and 24 months for participants in the voluntary phase.

| Modified Clinical Test of Sensory Integration in Balance | Modified Clinical Test of Sensory Integration in Balance test evaluates how different sensory inputs contribute to balance control by assessing balance tasks performed under different sensory conditions: eyes open, firm surface; eyes closed, firm surface; eyes open, foam surface; and eyes closed, foam surface. Scores are based on the time the participant can maintain balance (0-30 seconds for each task, with the maximum score being 120 seconds for all tasks, higher scores reflecting good sensory integration and balance control). |
