Scatter plots showing the effects of lengthening velocity and DCS on maximal force, firing rate, and threshold force in mice with SCI. At baseline (left panels, black trace), both maximal force and firing rate were velocity dependent; however, threshold force was velocity independent. During spinal-to-sciatic (Sp-Sc) DCS (middle panels, red trace), both maximal force and firing rate were velocity independent; however, threshold force was velocity dependent. During sciatic-to-spinal (Sc-Sp) DCS (right panels, green trace), maximal force, firing rate, and threshold force were velocity independent.
