Impact of the Atlas 2030 Pediatric Exoskeleton on Gait Functionality and Quality of Life in Children With Cerebral Palsy or Related Conditions

Plain-language summary

Title of the Study IMPACT OF THE ATLAS 2030 PEDIATRIC EXOSKELETON ON GAIT FUNCTIONALITY AND QUALITY OF LIFE IN CHILDREN WITH CEREBRAL PALSY OR RELATED CONDITIONS Justification Cerebral palsy and gait rehabilitation It is estimated that around 93 million children worldwide have some form of moderate or severe disability. Cerebral palsy (CP) is the most common motor disability in children, with a prevalence of 1.8 per 1,000 live births in Europe. CP causes severe motor dysfunction, sometimes resulting in the inability to stand or walk. This is due to damage in areas of the central nervous system (CNS) that control movement and posture. CP causes a series of signs and symptoms such as spasticity, muscle contractures, incoordination, loss of selective motor control, or weakness, which interfere with motor function and daily living activities in these children. As part of physical therapy, there are different types of pediatric robotic devices that assist with gait. These include: Lokomat, a stationary treadmill-based device; the G-EO System, which is also stationary and has a stair-climbing function; Innowalk, which enables standing; and other similar devices like NX-A3, Robogait, and Walkbot-K. Also notable is Prodrobot, which differs from the above as it performs suspended walking. Walking has been shown to have physiological and functional benefits, including the prevention of muscle contractures, maintenance of bone density, and improvement of cardiovascular function. Booth et al., in their meta-analysis, suggest that gait therapy produces more beneficial effects in children with CP than conventional therapy. Moreover, effective and functional mobility-whether independent or aided by support systems-enhances children's abilities to interact with and explore their surroundings. In the treatment of neuromuscular diseases (NMDs), low-impact exercise and supported ambulation are highly beneficial. Robot-assisted gait rehabilitation involves integrating these electromechanical systems into treatment programs. Calderón et al. argue that robotic devices enable early gait retraining and that their benefits lie in increasing training volume while reducing fatigue for both the patient and therapists. This allows for more repetitions, consistency, and quality of treatments in a safe manner. Medical Device Description The ATLAS 2030 exoskeleton is a robotic active orthosis with 8 degrees of freedom, classified as a THKAFO-type device. It aims to improve the user's motor level, with the goal of not only increasing life expectancy but also reducing or delaying complications associated with disease progression or prolonged sitting. It is attached to the human body in a non-invasive manner without direct skin contact, using a physical interface based primarily on straps and braces. Its chassis is adjustable in length and width for children between 100 cm and 130 cm in height. It performs human walking with active mobility in a three-dimensional space, providing controlled movement in the sagittal and frontal planes. In addition to walking forward and backward, it replicates sit-to-stand and stand-to-sit movements. The ATLAS exoskeleton is optimized for children with neuromuscular diseases (spinal muscular atrophy, muscular dystrophies, myopathies, etc.) and cerebral palsy. The device also self-adjusts to the patient's strength and mobility needs thanks to ARES technology, which absorbs joint disturbances and ensures safe control of the exoskeleton. ATLAS 2030 evolves intelligently with rehabilitation progress. It is easily adjustable to the child's growth and can be put on in just 5 minutes. Main Objective To evaluate improvements in motor functions related to gait with the use of the ATLAS 2030 pediatric exoskeleton. Specifically, the following will be assessed: * Gross motor function * Range of motion in the lower limbs * Strength in various muscle groups of the neck, trunk, and limbs * Spasticity in the limbs * Increase in gait capacity Study Design Observational study under routine clinical practice with pre-, post-, and follow-up measurements Target Disease or Disorder Inability or severe difficulty with independent walking in children aged 2 to 14 years with disabilities due to cerebral palsy or related conditions Primary Outcome Measures * Gross Motor Function Measure (GMFM-66): Assesses gross motor function, defined as the number of motor activities the child can perform * 6-Minute Walk Test (6MWT): Measures the maximum distance the child can walk in six minutes, evaluated while using the exoskeleton Study Population and Total Number of Patients 20 children between the ages of 2 and 14, with Gross Motor Function Classification System levels III, IV, or V Treatment Duration 6 weeks of treatment and an additional 6 weeks of follow-up
