Table 3.

Non-injured and SCI group mean ASIA Impairment Scale (AIS) values and RMS amplitude values for the prime-mover muscles and functional EMG (fEMG) parameters, Similarity Index (SI) and Magnitude (Mag), for each motor task. Comparisons were made between SCI Initial values and non-injured group values and between SCI group initial and final values. Note that the SCI group changes were mostly in upper-limb muscles and their control.
