Russian Scientists Develop Safer Pneumatic Exoskeleton for Arm Rehabilitation

Scientists at Tambov State Technical University (TSTU) have created a new hybrid control system for a pneumatic exoskeleton designed to rehabilitate arms and shoulders. The technology aims to prevent injuries during therapy by using advanced modelling and simulation. It builds on the university’s earlier work with the NeuroStep rehabilitation system. The team faced a key challenge: active exoskeletons can cause collisions between mechanical parts, risking harm to patients. To solve this, researchers analysed over 758 million spatial positions of the device. This data helped generate a safe matrix of operational states, ensuring smooth and secure movement.

The exoskeleton’s pneumatic actuator works like a natural damper, absorbing sudden muscle spasms without causing injury. TSTU engineers combined mathematical modelling with high-performance 3D simulations to refine the system. All software for the device was developed internally by the university’s engineers and student programmers. The university stressed the importance of technological independence, allowing hospitals to quickly adapt the equipment to their needs. This latest development focuses specifically on upper-limb recovery, expanding the capabilities of their rehabilitation tools.

The new algorithm removes the risk of patient injury during exoskeleton use. With its safe, adaptive design, the system is now ready for practical application in medical settings. Hospitals can integrate the technology into their rehabilitation programmes without relying on external software.
