Aerospace technology is showing potential in helping people with ataxia, a movement disorder that affects balance. Researchers led by Bram Sterke from multiple Dutch universities found that a robotic backpack device allows individuals with ataxia to stand and walk more steadily, reducing the need for mobility aids like walkers.
The backpack, called Gyropack, uses gyroscopic technology similar to that found in space stations and large satellites to help maintain orientation. Designed for medical use, it contains rotating wheels that resist trunk movements, improving posture and stability.
Understanding Ataxia and Its Challenges
Ataxia occurs when the cerebellum does not function properly, leading to coordination and balance difficulties and a higher risk of falling. Professor Jorik Nonnekes of Radboud University noted that many patients—often young—depend on walkers, which can be heavy, awkward, and stigmatizing.
The preliminary study included fourteen patients with moderate to severe ataxia. Each participant completed balance and walking tasks in three scenarios: without the backpack, with the backpack fully activated, and with the gyroscopes spinning but providing no stabilizing effect. This final setup served as a control, as it produced the same sound and vibrations as the active mode.
The greatest improvements occurred when the gyroscopes were fully engaged. According to Nonnekes, patients were clearly more stable and could, for instance, walk in a straight line much more effectively.
Even when the gyroscopes were inactive, the backpack still offered benefits, likely because its roughly six-kilogram weight helped steady the upper body.
Future Improvements and Potential Impact on Daily Life
The researchers plan to further refine the device by improving usability and reducing its weight and noise. While the backpack is not yet practical for everyday use, Nonnekes believes it could eventually allow people with ataxia to move more independently in daily life—such as attending social gatherings—without relying on walkers, which are often seen as heavy and inconvenient, ultimately enhancing mobility and quality of life.
