Table 4.
Comparison of Similarity Index (SI) and Magnitude values for SCI group members whose American Spinal Injury Association Impairment Scale (AIS) Grade, in 3 subjects, or neurological injury level improved in 6 subjects (n = number of sides). Note that AIS improvement was associated with significant increases in SI and Magnitude values primarily for upper-limb tasks for this group in whom impairment was initially most pronounced in the upper limbs.
