A team from Far Eastern Federal University (FEFU) has developed an adaptive motion control algorithm aimed at preventing shaking in rehabilitation robots used for stroke patients. This algorithm actively monitors changes in patient resistance during therapy sessions, allowing the robot to adjust its force output in real-time, thus reducing the risk of spasms that can occur due to sudden movements.
The significance of this development lies in addressing a critical issue in rehabilitation medicine: the risk of spasms, which affect 19% to 38% of stroke survivors in the first year. Traditional rehabilitation devices use fixed parameter PID control, which can lead to mismatches between commands and actual patient resistance, resulting in harmful shaking. FEFU's algorithm continuously updates control parameters based on real-time measurements, ensuring that the robot's movements remain within safe limits for the patient.
Looking ahead, the FEFU team plans to test their prototype within a medical complex on campus, with an estimated timeline of three years for this phase. Following testing, regulatory approval will be necessary for deployment, with local use in Russia not expected before 2029. This innovation highlights the importance of adaptive control in rehabilitation robotics, emphasizing the need for systems that can respond intelligently to patient conditions.
