Background:

Pattern recognition-based myoelectric control systems are extensively researched but rarely used clinically.
Classification accuracy is the primary metric, but its relation to system usability is under-explored.

Purpose of the Study:

To assess the usability of pattern recognition-based myoelectric control systems using a virtual clothespin task.
To investigate the relationship between classification accuracy and real-world system performance.

Main Methods:

Development and implementation of a virtual clothespin usability test.
Evaluation of pattern recognition myoelectric control systems with varying classification accuracies.
Comparison of standard classifier training with a clinically-supported approach including transient contraction signals.

Main Results:

Users can complete virtual tasks efficiently with systems demonstrating high classification accuracy.
A clinically-supported training approach, incorporating transient contraction signals, may decrease classification accuracy.
The inclusion of transient contraction signals in training can enhance real-time performance.

Conclusions:

Usability of myoelectric control systems is linked to classification accuracy.
Classifier training strategies impact the trade-off between accuracy and real-time usability.
Further research is needed to optimize myoelectric control systems for clinical application.
