Benign Effect of Extremely Low-Frequency Electromagnetic Field on Brain Plasticity Assessed by Nitric Oxide Metabolism during Poststroke Rehabilitation

Table 2

Clinical parameters: ADL, MMSE, and GDS measured in the ELF-EMF and non-ELF-EMF groups. Data presented as the delta of a clinimetric scale before and after the standard series of treatments (ΔADL = the increase of ADL; ΔMMSE = the increase of MMSE; and ΔGDS = the decrease of GDS).
