Percentage changes in group mean from pre to post of superimposed twitch (SIT), Voluntary activation (VA) with peripheral nerve (electrical) stimulation (N = 11) and cortical (TMS stimulation (N = 18) and MVC in the spinal manipulation (intervention) and passive movements (control) sessions across all participants. * represents p < 0.05.
