A new definition of poststroke spasticity and the interference of spasticity with motor recovery from acute to chronic stages
The relationship of poststroke spasticity and motor recovery can be confusing.“True” motor
recovery refers to return of motor behaviors to prestroke state with the same end-effectors …

The strength of the corticospinal tract not the reticulospinal tract determines upper-limb impairment level and capacity for skill-acquisition in the sub-acute post-stroke …
U Hammerbeck, SF Tyson, P Samraj… - … and neural repair, 2021 - journals.sagepub.com
Background. Upper-limb impairment in patients with chronic stroke appears to be partly
attributable to an upregulated reticulospinal tract (RST). Here, we assessed whether the …

Distinct corticospinal and reticulospinal contributions to voluntary control of elbow flexor and extensor muscles in humans with tetraplegia
Humans with cervical spinal cord injury (SCI) often recover voluntary control of elbow flexors
and, to a much lesser extent, elbow extensor muscles. The neural mechanisms underlying …
