Control of a Robotic Wheelchair Using Recurrent Networks

Luciano Boquete, Rafael Barea, Ricardo García, Manuel Mazo, M. Angel Sotelo
2005 Autonomous Robots  
This paper describes an adaptive neural control system for governing the movements of a robotic wheelchair.  ...  This model is used in two different control architectures to command the movements of a robotic wheelchair. The training equations and the stability conditions of the control system are obtained.  ...  Acknowledgments The authors would like to express their grateful thanks of the work carried out by the members of the SIAMO project; without their help the practical wheelchair tests could not have been  ...

Myoelectrically Controlled FES to Enhance Tenodesis Grip in People With Cervical Spinal Cord Lesion: A Usability Study

Rune Thorsen, Davide Dalla Costa, Ettore Beghi, Maurizio Ferrarin
2020 Frontiers in Neuroscience  
It compares to the impact that a mobility device like a wheelchair has on daily living. Fourteen subjects found the system useful, expressing the need for such a neuroprosthesis.  ...  Examples of acquiring new abilities while using the device, indicate that the method could have a therapeutic use as well.  ...  FreeHand system (Neurocontrol Corp., United States) was a good example of this kind of device which has been commercially available for a period, but it was eventually dismissed.  ...

Functional electrical stimulation after spinal cord injury: current use, therapeutic effects and future directions

K T Ragnarsson
2007 Spinal Cord  
In the absence of a cure, raising the level of achievable function in mobility and selfcare will first and foremost depend on creative use of the rapidly advancing technology that has been so widely applied  ...  This review presents an overview of the progress made, describes the current challenges and suggests ways to improve further FES systems and make these more widely available.  ...  Acknowledgements The preparation of this paper was supported in part by the National Institute on Disability and Rehabilitation Research US Department of Education (grant #133N060027).  ...

Abstracts of the 4th World Congress for NeuroRehabilitation

2006 Neurorehabilitation and Neural Repair  
Results: Our model was developed in early 1960s and our system had been originally adopted from the Western culture because of political reasons, as Hong Kong was a British colony.  ...  Conclusion: With the expanding Western influence in mainland China recently, we hope this integrated model can be implemented in other parts of China.  ...  Our aim is to verify the feasibility of a new method to deliver infiltrative therapy (5 mL of 1% of ropivacaina plus 1 mL of long-release glucocorticoids) by means of neurophysiologic guidance to the site  ...
