About

Neurodevelopmental disorders frequently result in abnormal development of the Central Nervous System (CNS), often leading to motor impairments such as difficulty in standing and walking. EXPLORER is a robotic exoskeleton for gait rehabilitation, specifically designed for adults aged 18 to 85 with motor disabilities.The aim of this study is to evaluate the safety and usability of the EXPLORER for adults with motor disability.

Full description

Neurodevelopmental disorders frequently result in abnormal development of the Central Nervous System (CNS), often leading to motor impairments such as difficulty in standing and walking. EXPLORER is a robotic exoskeleton for gait rehabilitation, specifically designed for adults aged 18 to 85 with motor disabilities. The aim of this study is to evaluate the safety and usability of the EXPLORER for adults with motor disability.

This study will involve testing the gait-assistance exoskeleton in healthy patients during the first phase, and in patients with stroke (ACV), acquired brain injury (DCA), multiple sclerosis (EM), and muscular dystrophy (LM) during the second phase. The study will consist of two phases:

Phase 1: One visit with the device in healthy patients to assess the initial safety and comfort of the device.

Phase 2: A screening visit (S0) followed by two treatment visits with the device (V1-V2) in patients with ACV, DCA, EM, and LM to determine the effectiveness of the device in treating motor impairments caused by these conditions.

The goal of the study is to evaluate the safety and usability of the device in patients with ACV, DCA, EM, and LM, in order to identify potential benefits in improving gait, muscle strength, and overall functionality in this patient group.
