Abstract
People with movement disabilities face difficulties in independent mobility. The main objective of this study was to develop and evaluate a real-time electro-myography (EMG) based wheelchair control framework with upper arm or neck muscles and to investigate feasibility for assistive mobility applications.
A feature optimisation framework was employed to extract the most significant features for movement recognition. The proposed model was trained and tested in both offline and real-time control. Feasibility was assessed through classification accuracy, repeatability measures, response latency and preliminary validation involving two individuals with disabilities.
With subject-independent methodology, wheelchair activation with upper arm muscles achieved an accuracy of 95% in real time, whereas for neck muscles, it was 98.6% in able-bodied participants. For neck muscles, two participants with disabilities, namely a transhumeral amputee and a mobility-impaired participant because of poliomyelitis were evaluated and achieved an accuracy of 100%. The average system response latency for upper arm movements was found to be 430 ms for able-bodied participants, whereas for neck muscles, it was 360 ms for able-bodied participants and 400 ms for participants with disabilities.
The proposed framework demonstrated the feasibility of real-time EMG-based wheelchair control in a controlled environment. However, further studies involving larger and more diverse participant cohorts are needed to evaluate its generalisability and broader clinical applicability.
