Voluntary co-contraction of ankle muscles alters motor unit discharge characteristics and reduces estimates of persistent inward currents

M. M. Gomes, S. T. Jenz, J. A. Beauchamp, F. Negro, C. J. Heckman, G. E. P. Pearcey

This study examines how voluntary co-contraction of ankle muscles affects motor unit discharge and reduces persistent inward currents (PICs) in motoneurons.

Intrinsic properties of spinal motoneurons degrade ankle torque control in humans

J. A. Beauchamp, G. E. P. Pearcey, O. U. Khurram, F. Negro, J. P. A. Dewald, C. Heckman

This study shows that intrinsic properties of spinal motoneurons, specifically persistent inward currents, degrade ankle torque control in humans during motor tasks.

Antagonist tendon vibration dampens estimates of persistent inward currents in motor units of the human lower limb

G. E. Pearcey, O. U. Khurram, J. A. Beauchamp, F. Negro, C. J. Heckman

This study shows that antagonist tendon vibration reduces estimates of persistent inward currents in human motor units during isometric contractions.

Estimates of persistent inward currents are reduced in upper limb motor units of older adults

A. S. Hassan, M. E. Fajardo, M. Cummings, L. M. McPherson, F. Negro, J. P. Dewald, C. Heckman, G. E. Pearcey

This study finds reduced persistent inward currents in older adults' motor units, linked to age-related decline in monoaminergic input and potential mechanisms for reduced firing rates and weakness.

Modulations in motor unit discharge are related to changes in fascicle length during isometric contractions

E. Martinez-Valdes, F. Negro, A. Botter, P. A. Pincheira, G. L. Cerone, D. Falla, G. A. Lichtwark, A. G. Cresswell

This study shows that changes in tibialis anterior fascicle length are closely related to motor unit firing rate and dorsiflexion torque during isometric contractions.
