Robotic Rehabilitation of the Upper Limb in Subacute Stroke

This multicenter international randomized controlled trial (RCT) evaluates the effectiveness of the Gloreha Sinfonia® robotic exoskeleton for upper limb rehabilitation in individuals with subacute post-stroke paresis. The study aims to determine whether robotic-assisted therapy improves voluntary motor control and coordination more effectively than conventional rehabilitation, as measured by the Fugl-Meyer Assessment (FMA) for the upper limb (motor component).

Participants will be randomly assigned to one of two groups:

* Experimental Group (EG): Robotic-assisted upper limb rehabilitation combined with conventional therapy. * Control Group (CG): Conventional therapy alone including upper limb rehabilitation.

Clinical assessments will be conducted at baseline (T1), post-treatment (T2), and at a 3-month follow-up (T3) using remotely administered scales.

Secondary objectives include evaluating improvements in muscle strength, range of motion, eye-hand coordination, manual dexterity, and functional independence. The study will also assess prognostic factors influencing response to robotic therapy, patient satisfaction, and potential adverse events.
