Feasibility of using combined EMG and kinematic signals for prosthesis control: A simulation study using a virtual reality environment.

Blana D, Kyriacou T, Lambrecht JM, Chadwick EK - J Electromyogr Kinesiol (2015)

Bottom Line: Transhumeral amputation has a significant effect on a person's independence and quality of life.The offline training had a target of 4° for flexion/extension and 8° for pronation/supination, which it easily exceeded (2.7° and 5.5° respectively).During online testing, all subjects completed the target-reaching task with path efficiency of 78% and minimal overshoot (1.5%).

f0020: The distribution of the values of the Index of Difficulty, for the targets used during the IMU-control phase (IMU) and the ANN-control phase (ANN).

Mentions: Fig. 4 shows the distribution of the values of the Index of Difficulty used in the experiment. The target size was fixed, so this depended entirely on the distance to target. The workspace used in the IMU-control phase was slightly larger than the workspace used in the ANN-control phase (so that the ANN did not have to extrapolate during use), thus the histogram for targets seen during training (black bars) includes slightly higher values than the targets seen during testing (median for IMU: 2.76 bits, interquartile range: 2.50–2.94 bits, median for ANN: 2.55 bits, interquartile range: 2.26–2.76 bits).
