Interlimb neural coupling allows upper limb (UL) activity to influence lower limb (LL) spinal excitability, yet the direction and magnitude of this modulation can vary across individuals. While rhythmic, locomotor-like UL tasks typically suppress soleus H-reflex amplitude, the effects of discrete voluntary UL movements remain unclear. The objective of this study was to determine whether rhythmic UL movements modulate soleus H-...

Hemiparetic gait due to stroke is characterized by an asymmetric gait due to weakness in the paretic lower limb. These inter-limb asymmetries increase the biomechanical demand and reduce walking speed, leading to reduced community mobility and quality of life. With recent progress in the field of wearable technologies, powered exoskeletons have shown great promise as a potential solution for improving gait post-stroke. While p...
