Body Weight Support Overground Treadmill Training (BWSOTT)


 As the patients have difficulty withstanding the load from their own body weight while walking, our Body Weight Support Overground Treadmill Training (BWSOTT) system reduces patients’ burden. Our system supports the weight through cable driven force control. Our research in BWSOTT aims to provide more natural walking conditions based on in-depth insight of the human walking process.                                                                                        

 

 

 

Ankle soft exoskeleton


 Soft exoskeleton can greatly enhance the limitations of previous ankle exoskeleton (heavy weight, unnatural movement) by reducing extra weight burden on wearer with a garment-type suit and power transmission based on Bowden cable. We aim to enable patients to achieve more natural ankle movements and provide personalized assistance according to their condition.

 

Predictive gait simluation


 Through ML-based simulations, it is possible to learn a patient's walking strategy and provide them with optimized walking assistance based on it. This not only significantly reduces the time required for Human in the Loop Simulation (HILS) but also greatly aids in understanding the distinct walking strategies of patients, distinguishing them from the healthy population.

 

 

Machine learning based gait clustering 


 The walking patterns of stroke patients can vary significantly based on factors such as the location of the lesion and the extent of recovery. It is essential to divide patients into similar groups to provide them with optimized training and assistance. To achieve this, research is being conducted to cluster patients based on their characteristics using ML-based unsupervised learning methods.
