Clinical Trial Summary

The purpose of the study is to test the technical functionality, safety, and feasibility of a bimanual robotic exoskeletal platform and associated serious games in order to offer information on technological and functional advances that will be included in the device's finalization.

In addition, a secondary goal will be to assess the therapeutic effects of a rehabilitation therapy based on the bimanual configuration, comparing it to a unimanual treatment delivered on the same platform (using the specific configuration).

Intervention

Device:
• Robotic rehabilitation using the Arm Light Exoskeleton Rehab Station (ALEx RS) and bimanual serious games
Patients will undergo a bimanual 30-session robotic rehabilitation, using the robot ALEx RS with the bimanual configuration and the related serious games. Each session will last 45 minute. Daily sessions will be provided, five days a week.
• Robotic rehabilitation using the Arm Light Exoskeleton Rehab Station (ALEx RS) and unimanual serious games
Patients will undergo a unimanual 30-session robotic rehabilitation, using the robot ALEx RS with the unimanual configuration and the related serious games.Daily sessions will be provided, five days a week.
