Interaction of poststroke voluntary effort and functional neuromuscular electrical stimulation

Nathaniel Makowski, et al.

Figure 5. Averaged stimulation response and standard deviation across participants.

Functional electrical stimulation from a neuroprosthesis in concert with voluntary effort may improve arm and hand movement after stroke. In order for this technique to be useful, we must know how the forces from voluntary effort and stimulation add together. In other words, does the stimulation response change if the user is relaxed or pushing hard? Our results indicate that if the user pushes harder, he or she receives a smaller increase in force as a result of the stimulation. This indicates that it may be advantageous to moderate effort when using a poststroke neuroprosthesis, allowing the stimulation to have a greater effect.
