 Our research suggests that children are less able to generate consistent EMG signals compared to adults which could limit their ability to control artificial limbs with multiple degrees of freedom. Additionally, children's performance improved with practice but at a slower rate than adults. This indicates that children may need more time to develop the same level of proficiency as adults when it comes to controlling prosthetic devices.
