Effects of spinal cord transcutaneous stimulation priming on single-leg balance control

Figure 2 Exemplary time course of center of pressure displacement and electromyographic activity. A: Time course of the center of pressure displacements in the anterior-posterior and medio-lateral directions, as well as electromyographic activity of tibialis anterior and medial gastrocnemius, during a representative single-leg stance performed before and after the priming protocol with spinal cord transcutaneous stimulation or sham stimulation with eyes open; B: Time course of the center of pressure displacements in the anterior-posterior and medio-lateral directions, as well as electromyographic activity of tibialis anterior and medial gastrocnemius, during a representative single-leg stance performed before and after the priming protocol with spinal cord transcutaneous stimulation or sham stimulation with eyes closed. scTS: Spinal cord transcutaneous stimulation; Sham: Sham stimulation; EMG: Electromyographic; AP: Anterior-posterior; ML: Medio-lateral; TA: Tibialis anterior; MG: Medial gastrocnemius; P: Posterior; A: Anterior; L: Left; R: Right.
