Overview
Moonwalker is the Khymeia system combining an immersive virtual reality environment with a 360° omnidirectional platform controlled by the patient’s central nervous system. It integrates cognitive, motor, postural and cardiorespiratory rehabilitation to leverage neuroplasticity and functional reserve, enabling rehabilitation approaches previously impractical.

Key features & concept
The system positions the patient on a secured omnidirectional platform with gravitational support providing adjustable body-weight relief up to 100%. Moonwalker delivers immersive VR scenarios with synchronized multisensory stimuli (e.g., scents, wind). Patients can walk freely in any direction (360°); the platform tracks movement in real time to provide natural gait paths and spontaneous motor activation.

Clinical applications

• Neurological rehabilitation (motor and cognitive domains)
• Orthopedic rehabilitation
• Cardiorespiratory rehabilitation and monitoring
• Pediatric applications: Moonwalker Kids — adapted solutions for developmental ages

Modular solution set (modules & brief descriptions)

• Motor Skills: treatment and training for all body segments and joints, including trunk, head and cervical regions. Extensive sensor dataset supports depth and full-body motion; compatible with EMG and Cognitive modules.
• Neuromotor Skills: assessment tests and rehabilitation scenarios for a range of pathologies, from basic tasks to complex ecological reconstructions.
• Omnidirectional walking: supports natural 360° gait (forward, lateral, backward, diagonal) while keeping the subject centered, harnessed and optionally body-weight relieved.
• Fall prevention: evaluations based on international scales (e.g., Berg Balance Scale, Brief BEST Test). Sensorized subject and OAK system produce objective, reportable results.
• Immersive VR: pathology- and activity-oriented VR modules integrated with the VRRS engine for motor, cognitive and ADL simulation and rehabilitation.
• Postural: balance exercises, posturographic tests, weight-shifting, reaching, balancing and strengthening exercises using associated devices.
• Cognitive: domain-specific exercises — memory, praxia, spatial orientation, attention, executive functions and calculation.
• Respiratory: integrated monitoring devices for respiratory rate, heart rate, ECG, pulse oximetry, spirometry and inhalation/exhalation phase control.

Operational & installation advantages
The electric lifting platform for wheelchair access rises from the system base to the working surface and retracts after patient positioning, minimizing footprint and adapting to gyms and compact rooms.

Use cases & patient groups
Designed for orthopedic, neurological and cardiological patients across acute and developmental ages, including individuals requiring weight relief and multisensory stimulation to elicit natural motor patterns and functional reserves.
