The impact of recovery of visuo-spatial neglect on motor recovery of the upper paretic limb after stroke.

The aim of the current study was to investigate the longitudinal relationship between improvements of synergism and strength of the upper paretic limb and severity of visuo-spatial neglect during the first 52 weeks post-stroke. The longitudinal association between severity of VSN and motor impairmen...
