Hand Solo is a real video game — fly through asteroid fields, dodge debris with finger gestures alone. Every motion of your hand teaches us how the human brain learns. Anyone can play. The data feeds a neuroscience lab.

// WHY WE UNDERTAKE THIS PROJECT
// 01 / THE PROBLEM
Stroke in Argentina and the World
Stroke is one of the leading causes of acquired disability in adults. In Argentina, it is estimated that there are more than 120,000 new cases per year. While some motor recovery occurs spontaneously during the first few months, approximately 50% of survivors progress to a chronic phase (>6 months) with persistent motor impairments.
// 02 / THE GAP
Effective Treatments, Limited Access
In recent years, rehabilitation has incorporated movement relearning approaches based on neuroplasticity principles, which have been shown to induce motor improvements even in chronic patients. However, these approaches require intensive protocols with close professional supervision. Despite their effectiveness, these interventions are unlikely to significantly impact the population burden of chronic stroke.
// 03 / OUR RESPONSE — HAND SOLO
Scalable, Home-Based Motor Relearning
It is necessary to develop rehabilitation solutions that translate the principles of effective motor relearning into scalable, low-cost, outpatient formats that can be implemented in the patient's home.
The proposed development consists of an outpatient solution based on the integration of an immersive virtual reality (VR) video game and a surface electromyography (sEMG) module linked to an artificial intelligence algorithm.
The video game involves controlling the movement of a spaceship traveling through space using specific hand gestures to avoid colliding with asteroids — opposition of the thumb to the index and middle fingers, opening and closing the pincer grasp, and moving the hand to the right or left.
