Figure 4. VNS-dependent recovery generalizes to similar, but untrained, forelimb tasks.
(A) SCI reduces the total number of forepaw contacts on the cylinder task. VNS paired with rehabilitative training on the isometric pull task significantly increases spontaneous forelimb use during exploration compared to rehabilitative training without VNS, indicative of a generalization of forelimb recovery to a similar task. (B) Pairing VNS with training on the isometric pull task significantly increases grip strength compared to rehabilitative training without VNS. Unpaired t-tests across groups at each time point; ** denotes p < 0.01, *** p < 0.001. Error bars indicate mean ± SEM.
