Comparisons were made between SCI first assessment values and neurologically intact group values (*p < 0.05, **p < 0.01). SI: similarity index, Mag: magnitude, BShAb: bilateral shoulder abduction, BShAd: bilateral shoulder adduction, EF: elbow flexion, EE: elbow extension, WFu: wrist flexion with palm up, WEu: wrist extension with palm up, WEd: wrist extension with palm down and WFd: wrist flexion with palm down.
