Influence of posture and stimulus parameters on post-activation depression of the soleus H-reflex in individuals with chronic spinal cord injury

EC Field-Fote, KM Brown, SD Lindley - Neuroscience letters, 2006 - Elsevier

Modulation of flexion reflex induced by hip angle changes in human spinal cord injury

M Knikou, E Kay, WZ Rymer - Experimental brain research, 2006 - Springer
The flexion reflex can be elicited via stimulation of skin, muscle, and high-threshold afferents
inducing a generalized flexion of the limb. In spinalized animal models this reflex is quite …
