Spatial analysis of muscular activations in stroke survivors

I don't see how this helps us get to 100% recovery.

Abstract: Study investigated the spatial patterns of electrical activity in stroke-affected muscles using the high density surface electromyogram (sEMG) grids. sEMG signals were acquired from the impaired as well as contralateral biceps brachii muscles of stroke survivors and from healthy participants at various force levels from 20 to 60 percent of maximum voluntary contraction in an isometric non-fatiguing recording protocol. The spatial sEMG pattern was found to be consistent across force levels in healthy and stroke subjects. However, once compared across sides (left vs right in healthy and impaired vs. contralateral in stroke), the stroke-affected sides were found to be significantly different in distribution pattern of sEMG from the contralateral side. The sEMG activity areas were significantly shrunk on the affected sides indicating muscle atrophy due to stroke.
