Evaluation of a Portable EMG-Controlled Hand Exoskeleton With Independent Digit Actuation
Summary
The novel Bidirectionally Actuated Cable (BAC)-Glove shows promise for improving hand function in individuals with motor deficits. This assistive device demonstrated robust capabilities and viable electromyography (EMG) control for object manipulation tasks.
Area of Science:
- Biomedical Engineering
- Rehabilitation Technology
- Neuroscience
Background:
- Chronic motor deficits, especially in hand function, are common post-stroke.
- Hand exoskeletons offer potential for functional improvement but require task flexibility.
- The Bidirectionally Actuated Cable (BAC)-Glove is a novel device designed for independent digit actuation.
Purpose of the Study:
- To assess the robustness and utility of the BAC-Glove.
- To evaluate the device's digit movement and fingertip force capabilities.
- To examine the viability of electromyography (EMG) control for the BAC-Glove.
Main Methods:
- Assessed digit movement and fingertip force in 5 neurotypical participants using motion tracking and load cells.
- Trained 10 neurotypical participants on EMG control over four sessions.
- Evaluated user performance with the BAC-Glove before and after training.
Main Results:
- The BAC-Glove achieved coordinated flexion/extension of finger joints and produced peak forces of 15.1 N (flexion) and 9.6 N (extension).
- Participants demonstrated significant improvement in object manipulation tasks (e.g., Box and Block test) with EMG control over training sessions (p < 0.05).
Conclusions:
- The BAC-Glove is a robust device with potential for assisting activities of daily living.
- The EMG control scheme is viable and warrants further investigation in clinical populations for hand function rehabilitation.
