Key result
Motor imagery of isometric thenar muscle activity at 50% and 100% maximum voluntary contraction significantly increased spinal motor neuron excitability (F-wave persistence 92.9% vs 52.6% at rest) and cardiac sympathetic nerve activity.
Why the study?
Does motor imagery of isometric thenar muscle activity at different contraction strengths increase spinal motor neuron excitability and cardiac sympathetic nerve activity in healthy subjects?
Does motor imagery of isometric thenar muscle activity at different contraction strengths increase spinal motor neuron excitability and cardiac sympathetic nerve activity in healthy subjects?
Motor imagery of isometric muscle contraction increases both spinal motor neuron excitability and cardiac sympathetic nerve activity, independent of the imagined contraction strength.
Hypothesis-generating for motor imagery effects on sympathetic activity; leaves open clinical translation and patient outcomes.

Bunno et al. (2016) studied Healthy subjects (n=10). Motor imagery of isometric thenar muscle activity vs. Rest was evaluated on F-wave persistence during 50% MVC motor imagery (p=<0.01). Motor imagery of isometric thenar muscle activity at 50% and 100% maximum voluntary contraction significantly increased spinal motor neuron excitability (F-wave persistence 92.9% vs 52.6% at rest) and cardiac sympathetic nerve activity.
