From: Improving internal model strength and performance of prosthetic hands using augmented feedback
Task | Description |
---|---|
Control Practice | Control the prosthetic hand for two minutes – a combination of close/open the prosthetic hand and abduct/adduct the thumb. |
Training and Familiarization | 25 trials of grasp-and-lift of the iVE with the breaking feedback and 15 grasp-and-lift trials without the breaking feedback. Each trial lasted for seven seconds. |
Adaptation rate test | A total of 40 grasp-and-lift trials. Each trial lasted for five seconds. |
Perception threshold test | Grasp-and-lift the iVE in less than four seconds and identify the trial with the added stimulus in a set of two trials, repeat this task until convergence of an adaptive staircase. |
Performance test | Transfer the iVE from one side of a barrier to the other 20 times in less than 10Â s per transfer. |
