Figure 6. Limb asymmetric muscle response during TSS above and below the lesion in participants with cervical spinal cord injury.

Figure 6

The limb amplitude differences between the limbs for all tested UL muscles during stimulation above (C3–4 vertebrae) and below (C7-T1 vertebrae) the lesion for all participants. The intensity of stimulation was adjusted based on the maximum tolerated intensity of the participant, which ranged from 10 to 150 mA. The line plots shifted to the left indicate that the left limb had a greater amplitude than the right limb, whereas the line plots shifted to the right indicate that the right limb had a greater amplitude than the left limb. TSS: transcutaneous spinal stimulation, BIC: biceps brachii, TRIC: triceps brachii, FCR: flexor carpi radialis, ECR: extensor carpi radialis, FDI: first dorsal interosseous, APB: abductor pollicis brevis muscles.
