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.

A geometric approach to quantifying the neuromodulatory effects of persistent inward currents on single motor unit discharge patterns

J. A. Beauchamp, G. E. P. Pearcey, O. U. Khurram, M. Chardon, C. Wang, R. K. Powers, J. P. A. Dewald, C. Heckman

This paper introduces a geometric method to quantify neuromodulatory and inhibitory effects on motor unit discharge patterns using metrics like brace height and slopes, validated on simulated and human data.

Variability of in vivo sarcomere length measures in the upper limb obtained with second harmonic generation microendoscopy

A. N. Adkins, R. Fong, J. P. A. Dewald, W. M. Murray

This paper quantifies variability in in vivo sarcomere length measurements using second harmonic generation microendoscopy in upper limb muscles and estimates measurement uncertainty.

Serial sarcomere number is substantially decreased within the paretic biceps brachii in individuals with chronic hemiparetic stroke

A. N. Adkins, J. P. A. Dewald, L. Garmirian, C. M. Nelson, W. M. Murray

This study finds that chronic hemiparetic stroke reduces serial sarcomere number in the paretic biceps brachii, leading to shorter fascicles and increased passive resistance to elbow extension.

Reduction in voluntary activation of elbow and wrist muscles in individuals with chronic hemiparetic stroke

L. R. P. Garmirian, J. P. A. Dewald, A. M. Acosta

This study quantifies voluntary activation differences in elbow and wrist muscles of stroke patients compared to controls, finding reduced activation in paretic limbs and greater interlimb differences at the wrist.

Volume and intramuscular fat content of upper extremity muscles in individuals with chronic hemiparetic stroke

L. R. P. Garmirian, A. M. Acosta, R. Schmid, J. P. A. Dewald

This study quantifies muscle volume and intramuscular fat in stroke survivors, finding reduced muscle volume but no significant increase in intramuscular fat in the paretic limb.
