FIG. 3.

Reduced EMG amplitudes of motor maps after SCI. (A) Comparisons among all groups of average peak amplitudes of responsive spots along medial-lateral axes of the mapping areas. (B) Comparisons among all groups of average peak amplitudes of responsive spots along anterior-posterior axes of the mapping areas. In both directions, there were great decreases in amplitudes on day 1 post-SCI and gradual recovery in 2, 4, and 6 weeks post-SCI in all injured groups, with the mild SCI > moderate SCI > severe SCI group in recovery. (C) Mean amplitudes of responsive spots of individual maps at baseline, 1 day, and 2, 4, and 6 weeks after SCI. *p < 0.05; **p < 0.01; ***p < 0.001, one-way ANOVA. ANOVA, analysis of variance; EMG, electromyogram; SCI, spinal cord injury. Color image is available online at www.liebertpub.com/neu
