The gyroscopic backpack improves balance in ataxia patients

An innovative backpack, containing aviation technology, is promising as a help for patients with a motor disorder. Research conducted by the Radboud University Medical Center, in cooperation with Delft University of Technology (TU DELFT) and Erasmus MC, reveal that the backpack helps people with ataxia in the state and walk more gradually, reducing their relief to help mobility, such as Walkers.

Ataxia is a neurological state in which the cerebellum, part of the brain responsible for coordination, works improperly. This leads to problems with balance and coordination, increasing the risk of falls.

Some people with ataxia, often young people, depend on the walker. These devices can be heavy and bulky, and many patients consider them stigmatizing. “

Space age technology

The backpack, known as Gyropack, uses gyroscopic technology similar to the one used at space stations or large satellites to maintain orientation in space. The backpack is developed in the Vallery group in Tu Delft and Erasmus MC for over a decade. “When I found out about it, I immediately saw his potential to help people with ataxia,” says Nonekes. Carefully working with the TU Delft team, the backpack was optimized for medical use. It contains rotating wheels that generate resistance to the rotating torso, which causes better attitude and balance.

Balance exercises

Fourteen patients with moderate to advanced ataxia took part in the study. Participants performed balance and walking exercises in three conditions: without a backpack, with a fully functioning backpack, and the gyroscopes turned, but without generating any useful effect. The last state was a stirred condition, which was indistinguishable in sound and vibrations from active support. Even without active gyroscopes, the backpack brought noticeable benefits, which due to the current mass of about six kilos, which helps stabilize the upper body. However, the most important improvements were observed when gyroscopes were active. “Patients were clearly stable and could, for example, walk on a straight line much more,” notes Nonkes.

Looking to the future

The research team aims to further develop a backpack, focusing on user friendliness. Ideally, the device will become lighter and quieter. “It is not yet suitable for everyday use,” says Nonkes, “but in the future it can help people with ataxia in participating in everyday life, such as participation in social events without the need for a walker, which many consider to be abundant and uncomfortable. This can significantly increase their mobility and overall quality of life.
